"Northern jujube and southern species," the new technology of pendulous pruning high-yield, "Northern jujube and southern species," not only to cultivate new varieties adapted to the southern climate many fruiting, but also to explore a set of new techniques to adapt to multiple fruiting. In addition to cultivation mode, we used pruning pruning. Comparing the experimental bases in Sichuan, Yunnan, and Guangxi, they all reached three fruiting dates in the first year, and the output in the second year was as high as 2,500 kg. The technology was identified by the China Fruit and Vegetable Expert Committee. Tests have proved that this method has ten major features and are briefly introduced to you. First, to highlight the contradiction between high production, improved quality, and strong nutrient growth in the production process of red jujube. First, the biggest difference between sagging pruning technology and northern jujube tree pruning lies in the difference in the height of jujube tree drying, which is 1.2 meters in the south. The minimum is not less than 1m. The second is the treatment of Wang branches. In the northern jujube tree pruning, a large number of long branches are cut off. Although the control is prosperous, it also results in a large amount of nutritional waste of the jujube tree, while the pendulous pruning is a large number of papers with long lengths that will grow up to a certain length. The branches are twisted and fixed downwards, and then they are transformed from vegetative growth to reproductive growth by changing the growth direction, which greatly prevents the growth of jujube trees. This not only destroys the growth potential of jujube trees, but also adjusts the nutrient distribution of jujube trees. All the nutrients of the long branches were left, and the fruits were turned several times. This method must be carried out in conjunction with pull-drying and pull-branches to achieve fruiting three or four times a year. It not only has many fruit-bearing results, but also has many fruits, large fruit, and good fruit quality. Hainan Xinkehui Agricultural Development Co., Ltd. used this method very successfully. In March, the "Guitai No. 1" and "16 green" series of varieties were planted. As early as the end of June, the first crops matured. At the same time, secondary fruit appeared. In August, the second fruit has entered an expansion period, and the third fruit is in large quantities. Flowering, some fruit has been set. Second, suitable for dense planting, saving time and labor The technique uses the technique of pruning, without girdling, ring cutting, just constantly twisting branches, pulling branches, so that the branches are evenly distributed, the whole tree to achieve drooping, this model is suitable for close planting. Because the tree is small and the result surface is concentrated, it is easy to manage. It is through this method that we have planted 333 and 444 plants per acre in Meishan, Sichuan and Chuxiong, Yunnan. As we all know, the Aksu high-yield demonstration in Xinjiang is closely planted to 666 per acre with a yield of 3,416 kilograms, which is the highest in China's jujube output and awarded by the Chinese Red Jujube Association as a “Chinese Zaoyuanâ€. We use a plant spacing of 1m, a row spacing of 1.5m and dense planting of up to 444 per acre. In Hainan, it reached 500kg in the year, 2,500kg in the second year, and 3500kg in the third year. In addition, the use of row spacing 1.5m, spacing 50cm, up to 888 per acre, the first year output of 1,000 kg, the second year of 5000 kg, plans to create the best in China. Third, it is simple and easy to adapt. Many times we adapt to fruiting. We have investigated through 36 bases in six provinces (cities). This method can bear fruits in the first year, and can even be fruited twice. The first year Wugang Base in Shaoyang City, Hunan Province has a yield of 500 kilograms per mu. It not only bears more fruit, but also has a large fruit size and high yield. Yunnan Yuanmou County bases the gold silk “Guitai†series of fresh dates with a sugar content as high as 42.8%. The northern morning city is 45 days. In 2008, the fresh dates of Yunnan and Guangxi were the only fresh dates sent to the Olympics (China’s specialties newspaper reported). Fourth, suitable for dwarf close planting, yield greatly improved Guangxi Nanning Xixiangtang base The new Zao Park 2000 kilograms per mu in the second year, is the production of ordinary red dates doubled. In Yuanmou County of Yunnan Province, this method is used to transform the old trees to increase production at multiple times, and the yield per mu reaches 1,500 kg. The southern jujube used dwarf dense planting to reach 444 plants per acre, and the output could reach 2000 kg. After being able to promote it in Hainan, not only the high yield but also the morning market. Open cultivation can be listed on the May 1st. The Yayuan Township Haiyuan Company of Sanya City planted the "Guitai No. 1" variety in December last year. It germinated and pumped branches in January and fruited heavily in March. It entered fruit-expansion period in April. When Secretary General of China Fruit and Vegetable Experts Committee, Secretary Zhen Zhongzhong visited in May, I am very surprised that the fruit is large and brittle, red and sweet, and it is considered a miracle. It has provided a demonstration for Hainan's massive development of the "Northern jujube and southern species." This year, the first fruits of Wenchang Base of Hainan Xinkehui Agricultural Development Co., Ltd. all matured in July. The second batch of fruit matured at the end of September. The third batch of fruit must mature in early November to welcome the upcoming Chinese Fruit and Vegetable Expert Committee. The 7th Expert Forum Annual Meeting was visited. 5. Adopting comprehensive measures to ensure that the high-quality pruning method of fresh jujube makes full use of the characteristics of the “Guitai†series and the “16 green†series of curved branches and branches, and that the branches are easily pressed. In the case of adopting comprehensive measures, the fresh jujube hanging can be used. A lot of fruit. Because of the short tree shape, the light inside and outside the tree has truly reached high quality and achieved “big, red, sweet, crispâ€. Nanning Xixiangtang base has a maximum fruit weight of 108 grams, 2/3 is red, sugar content is as high as 38%, and the fruit surface is bright, and it really achieves high yield and high quality. Fresh dates planted at the base of Meishan City, Sichuan Province, have been booked and sold for as much as RMB 40 per kilogram. Yunnan Yuanmou County "Gold Silk" series of sugar content not only reached more than 40%, the price is as high as 40 yuan per kilogram, the earliest to enter the Beijing supermarket. The so-called comprehensive measures are followed by fertilizers and water, “sea and air and airâ€, and extra-root fertilizer (foliar fertilizer). The foliar fertilizer is mainly Tianda 2116 nutrient solution. From germination to fruit ripening, spray 2116 800 times once every 10 days and root once every 15 days (day 2116 plus brown sugar plus Tianda silicone and urea). Above the leaf spray, ground fertilizer attack, root nutrient solution input. In addition, you can also use the method of hanging a needle and tree injection on the tree. It is this integrated management that guarantees a large number of fruiting. Sixth, the use of standardized management, but also interlocking pruning pruning makes the tree into an easy-to-manage state. Only about 1m between strains and strains, between the line and the line is also easy to manage. Trimming, watering, and spraying are extremely convenient. Especially when sprinkler irrigation is used, water conservation is also timely. It is truly “dry and pourable, and can be drained,†and the humidity during flowering is maintained. Continuous technical training for management personnel, and Hainan University students in batches internship at the base, to reach the colleges and universities, corporate relations, give full play to their advantages, base to produce results, promote the demonstration of results, demonstrations to promote farmers, nursery stock market, help farmers get rich, farmers It also creates benefits for companies and research institutes, all relying on standardized management and high-tech talent. The company not only has more than 10 professors and experts, but also has the backing of universities and research institutes to support the transformation of scientific research results. Seven, comprehensive use of biological control, prevention and treatment of pests Southern jujube tree cultivation often have a large number of pests and diseases, we use prevention and treatment methods, regular spray biological pesticides, install pest control pest control of the purple light, to really achieve prevention and treatment. As we all know, the main sparse-stratum and spindle-shaped trees need to be repeatedly sprayed on the front and back when spraying, but there are still dead spots. The use of pendulous pruning jujube trees, from top to bottom, branches arranged in an orderly vertical, spray spray regardless of whether the spray or oblique spray, leaves, fruits can be sprayed everywhere, the control effect is excellent. In addition to good spraying effect, the foliar fertilizer can also be easily sprayed, so that the leaves are large and thick, and the leaves are glittering, making the Tianda 2116 nutrient solution fully show its power. VIII. Hainan winds are large and large, dwarfing is extremely beneficial to wind prevention until September 2009, and there have been three or four gales. The base fresh dates have no major impact. First, we use a short wood bracket; the second is dwarfing, pulling branches, the branches are not easy to shake. As a result of drooping branches, three-dimensional fruiting inside and outside, but also reduce wind damage. Hainan development of jujube must pay attention to wind, otherwise it is difficult to succeed, to achieve high efficiency. Nine, tree balance, reaching multiple fruiting consecutive years We all know that the northern jujube is mostly traditional pruning methods, in principle, "go strong, stay in, raise weak branches", this method is to a certain extent, retrograde jujube As a result, the large amount of trees will be pruned in the coming year, and after trimming, the tree vigor will be greatly reduced. The use of dwarfing buds for pendulous pruning adopts the principle of “strongly pulling branches, raising middle branches, and clearing dense twigs†to adapt to the requirement of fresh jujube in the south, and to make the jujube tree nutrition be used rationally. Because the main branch directly branches to the resulting branch, there are many branches and branchlets, which greatly increases the result area. There are more than 180,000 branches per acre, and 90% for short branches. This not only stabilizes the tree vigor, but also lays a solid foundation for many fruit production and high yields. 10. The tree shape facilitates the use of a hedge to prune new trees and achieve dwarfing and dense planting of fruit for many times, which is conducive to sightseeing. Such an expansion of the model is a very good sightseeing park. The income from sightseeing and tourism is huge, and it also drives the development of the tertiary industry. With the construction of an aviation city, the number of tourists in Wenchang, Hainan, has increased dramatically. We plan to expand it into a sightseeing date garden. The following describes the establishment of garden management: (A) dwarf planting to achieve a reasonable density of pruning pruning, tree-shaped canopy medium volume, although the amount of large branches per acre, but most of the branches drooping, do not interfere with each other, very conducive to ventilation Translucent, so very suitable for high density. The minimum is 444 per mu and the maximum is 888 per mu. If you use a plastic greenhouse facility, you can grow up to 1,200 plants per mu. To develop the production potential of sagging pruning technology, we must build a park with high quality. In order to increase the permeability of the soil, it is beneficial to the rapid growth of the root system after the survival of the seedlings. The planting trench must be dug, and the width and depth must strive for 80cm, especially in the north-south direction. The bottom layer of rotten straw, apply circle fertilizer, 5000 kg per mu, compound fertilizer 40 kg. (B) Sapling shaping method should be properly established in the first year of planting planting seedlings should be selected, 1.2m after the second year old seedlings will be set to dry, cut under the 20cm for the plastic band, after budding to retain the plastic band within the bud, the key is to pull Bent trunks stimulate the sprouting of main trunks, cultivating a large number of fruiting branches, and ensuring the year of fruiting and fruiting in the current year. (c) In the spring of the second year, the main branch is pulled for germination. The distance between the buds is about 20cm. After the flattened main branch, a large number of prosperous shoots will be issued. For these upright new shoots, too dense can be removed. The rest is allowed to grow. The spacing between the shoots is appropriate from 20cm to 30cm. . These new shoots have grown to more than 80 cm and are lignified after falling to autumn. At this point the branches are twisted to the ground, and then the branches are twisted with a string or wire, but they cannot be twisted so that they form a drooping branch. (D) At the end of winter cut, the central trunk extending upwards will be cut short again at a distance of about 1.2 m from the main branch of the second layer, and the third main branch will be cultivated. In the third year, in spring and autumn, the main branch of the second floor was carved and pulled according to the management method of the first branch, and then the main branch of the third floor was cultivated according to the main branch of the first floor and the second floor. The four main branches are left in the layer and are distributed at 90 degrees, and they are staggered with the lower main branch. When the autumnal cut ends at the end of winter, the central trunk no longer remains. The overall tree is below 2m, and the maximum is also less than 2m. In the fourth year, according to the management methods of the main branches of the first and second floors, the main branch of the third floor was carved and pulled. At this time, the entire tree is completed. As long as the density reaches 444, the output can be stabilized at more than 3,000 kg. With 888 strains per mu, it can reach 5000 kg in the second and third years.

At this time, the entire tree is completed. As long as the density reaches 444, the output can be stabilized at more than 3,000 kg. With 888 strains per mu, it can reach 5000 kg in the second and third years.
