Zijiang people often use to pickle or make dish ingredients. Due to the large market demand, many growers planted it. Today, Xiaobian tells you about the cultivation technique of deep-grooving deep-growing of 20-mu.
Zijiang deep-plowing deep-groove cultivation technology is a new technology developed by experts of Guangxi Academy of Agricultural Sciences according to local climatic conditions and production levels. After long-term experiments by experts, deep ploughing and deep cultivation can increase yield by more than 20% per mu. Improve the economic benefits of farmers. So, what is the deep ditch, what are the specific standard requirements? What is the specific method of sub-Ginger deep-cultivation in deep ditch? Let's take a look.
Deep tillage refers to the depth of deep penetration reaching 50-60 cm, the benefits of this approach:
The first is to change the structure of the soil, to loosen the soil, prevent evaporation of water, and at the same time have good permeability. In general, it can play a role in draining and protecting the soil. Second, it can change the nutrient conditions of the soil and promote the decomposition of organic matter. To improve soil fertility; third, it can reduce the occurrence of pests and weeds.
Deep ditch refers to planting ginger in a planting ditch 25 to 30 cm deep, which can increase the ground temperature and achieve early harvesting of more than 15 days in advance. Advantages of deep ditch: Ginger has strict requirements on light. Deep ditch can create a relatively shady environment, avoid direct sunlight, meet the requirements of ginger for growing environment, and deepen the deep ditch to save labor and time.
Soil cultivation is the key to affecting the quality and yield of Zijiang. In the past, the soil used for soil cultivation was large. It was necessary to transport soil from the field and cultivate soil for 3 to 5 times, and the height of the soil was limited. Deep ploughing and deep gully cultivation is carried out only in three different stages of growth of ginger, and the soil is taken locally. The soil on both sides of the ditch can be directly piled up to make the ginger reach the desired length. very convenient.
Technical points for cultivation of deep ginger in deep gully:
Zijiang deep ploughing deep trench cultivation techniques, it is necessary to choose a relatively flat terrain, which is conducive to mechanical farming and suitable for the production of ginger. At the same time, ginger must be planted in a rotation mode of more than three years.
After the ginger deep ploughing the deep ditch, the soil should be sterilized by sun exposure for 3-5 days, and then apply 2000 kg of decomposed chicken manure per mu, 50 kg of ternary compound fertilizer with a ratio of NPK 15:15:15 and Bacillus. The effective viable cell count is greater than or equal to 100 kg of bio-organic fertilizer of 0.2 billion organic matter per gram or more of 50%, and then the palladium is evenly leveled.
In the selection of varieties, it is suitable for local varieties. Guangxi mostly chooses Guangxi big meat ginger, sparse round meat ginger, selects fat shape and flattened without pests and diseases, shiny ginger buds full of ginger, ginger in the sunny days 1-2 In the day, you need to turn the ginger block and avoid the direct sunlight in the noon. The ginger is cleaned with water and disinfected. It can be soaked in 40 times of formalin 100 times for 20-30 minutes. Each 50 kg of liquid can be used. Soak the ginger species 80 kg, put it out and stack it in a unified manner, and suffocate for 3-6 hours, which can effectively prevent the occurrence of ginger bacterial disease rot. After cleaning again, dry the water, cut the ginger into pieces, each piece has 1-2 buds on the ginger, the weight of the ginger is between 50-100 kg, and it is placed for 1-2 days. It can be planted.
Because Guangxi is dominated by soil, phosphorus is easily lost in the soil, and in the early growth stage of ginger, it needs to absorb a large amount of phosphorus to help it grow rapidly. Therefore, before the sowing, the effective ingredient per acre is 10% or more. Calcium phosphate 40 kg.
The sowing of deep ginger in deep gully cultivation is the same as the traditional method, but the amount of seed is relatively large, according to the plant spacing of 10-15 cm, the seed amount per acre is 750 g-850 g, and then the soil is 5-7 cm. Before the emergence of seedlings, the relative water content of the soil is about 50%. Because the ginger is planted earlier, in order to prevent freezing damage, it is necessary to keep the film moist and moisturizing. Until the end of February to the beginning of March, the ginger seedlings will drill the soil and grow rapidly. Once the temperature inside the planting ditch is higher than 30 degrees, it is easy to burn the ginger seedlings. At this time, we must breathe the film to cool down. Generally, there will be a cold spring before mid-April, in order to avoid the cold spring, the film can be completely opened after the middle and late April.
Field management: no deep mowing is used in deep ploughing cultivation. After the emergence of ginger, the soil should be kept moist, and the relative water content of the soil is about 70%. If it encounters high temperature and drought, the leaves should be watered in time, at 10 am or afternoon. After 4 o'clock, watch the rainy weather and pay attention to drainage and flood prevention.
Cultivating and cultivating soil: The soil is cultivated to prevent the roots of ginger from exposing the soil, or to expand to the sides, affecting the shape of the ginger. It is impossible to carry out the soil at one time, because if the soil is too thick, the growth of ginger will be more difficult. So we have to do the soil three times according to its different growth stages.
The first cultivation was carried out after the second ginger bud was unearthed, and the soil was also topdressed and fertilized. The ternary compound fertilizer and urea with a ratio of nitrogen, phosphorus and potassium applied in the gully before the soil were 15:15:15, 5 kg per acre, and the fertilizer was applied. After that, the soil on both sides of the ditch is covered in the ditch, and the depth of the soil is 5-7 cm.
The second cultivation was carried out 20 days after the first soiling, and the 3-4th buds were unearthed. This time, 10 kg of compound fertilizer was applied to each of the compound fertilizers with a ratio of urea and NPK 15:15:15. The second soil is 10 cm deep, and all the soil on the ridge is filled into the planting ditch, that is, the planting ditch is filled with soil. Pest control should be carried out after two soil cultivations. The main pests are beet armyworm, aphids, etc. The disease is mainly rot disease, following the principle of prevention and comprehensive prevention, avoiding the occurrence of pests and diseases from the root cause, and using physics as much as possible. For prevention and control, aphids can be controlled by yellow sticky insect boards, and insecticidal lamps can effectively kill adult beet armyworms. When using chemical methods to control pests and diseases, use biological preparations as much as possible, and use them under the guidance of technical personnel such as the local plant protection department. It is best not to spray any chemicals one month before harvesting.
The third soil was carried out 15 days after the second soiling. After the 4-6 buds were unearthed, 20 kg of compound fertilizer with a ratio of urea and NPK of 15:15:15 per mu was applied. Ditching and soiling between the planting rows, that is, turning the ditch into a ridge, the ridge becomes a ditch, and the height of the soil can reach 15 cm.
Harvest: Harvested on sunny or cloudy days from the end of May to the beginning of June, 15-20 days after the third cultivation.
The above is a small series of deep-ditch deep ditch planting techniques that can make the ginger grow high-yield. If you are interested, you can look at it.
