During the growth of cucumber, the leaf size of cucumber is critical and cannot be underestimated! Because some cucumbers have different leaf sizes, they may be varieties, but some are pest and plant invasion and planting management problems, and the cucumber leaves must be adjusted to ensure high yield. The growers have to follow the small series to see the cucumber leaf adjustment technology and management. Measures!
As we all know, the leaves have a great influence on the yield of cucumber, because it is a factory for making organic nutrients. It can be said that there is no yield without leaves. In production, the purpose of pest control is to protect the roots and flowers and fruit, and most of the measures taken are carried out around the protection of the leaves. The leaves are not sick, not yellow, and aging. Although they are the basis of high yield, they may not be truly high quality and high yield. Cucumber leaves must be adjusted to ensure high yields. The specific principles and measures are as follows:
The leaves are too small to reach a certain leaf area coefficient, the organic nutrients produced are less, the melons are small and small, the yield is naturally not high, and it is easy to prematurely decay. This situation does not exist in high-yield areas of cucumber. . If the leaves are too large, it proves that the vegetative growth is too prosperous and becomes a long-length type. When the organic nutrients supply a large amount of stems and leaves, the nutrients flowing to the melons are bound to decrease, and the melons will be thin. Many vegetable farmers have reported that the cucumber leaves are large and green. How to produce melons is not as good as the leaves. This is the saying that “the prosperous vines do not bear the melonâ€. Excessive cucumber leaves are related to the variety, mainly caused by improper management. For example, if the water is too large, high temperature and high humidity, it is easy to form large leaves. Xiao Bian believes that if the yield per mu is about 20,000 kg, the diameter of the middle and lower leaves should not exceed 20 cm, the average length of the internodes should not exceed 12 cm, and the total vine length should be more than 8 m. How to achieve such a growth indicator, the following measures must be taken in management:
First, pay attention to the number of fertilization types.
   The application of base fertilizer should be sufficient. For example, about 10 yuan of chicken, duck and pig manure can be applied. High-nitride fertilizer can not be applied again. High-potassium compound fertilizer should be applied, 100-150 kg per mu. Before the root melon is harvested, it is not advisable to apply high-nitrogen water-soluble fertilizer. Afterwards, the high-potassium and high-calcium package fertilizer Jiamei dividend, internal potassium, ocean star and nuclear power are good, and each time it is about 15 kg per mu.
Second, the seedling control and long control leaf is the basis.
   The 3-4 leaflets of cucumber begin to differentiate into flower buds, which is a key period to increase the number of female flowers and control internode elongation and leaf expansion. On the basis of reducing the supply of fertilizer and water, refining is an important measure. Strong light can shorten the internodes, making the leaves smaller and thicker, reducing shading and maximizing the light. The daytime temperature is controlled at around 25 °C, and at night it is 12-15 °C. Moderate low temperature can make the blade smaller. Appropriate spraying of auxin or chlormequat or paclobutrazol should be halved according to the instructions, and can be used continuously for 2-3 times depending on the situation.
The third is to adjust the growth of cucumber in time.
   After entering the initial fruit period, plant adjustments should be made in time to increase plant growth. When the cucumber enters the initial fruiting stage, some male flowers and deformed melons will sprout at the leaf stalks of the lower part of the plant. Xiaobian finds that some vegetable farmers ignore this. It is recommended that the vegetable farmers should remove them in time. First, they can reduce nutrient consumption and prevent excessive humidity. This infects the disease. In addition, the whiskers on the stems of cucumbers should also be removed in time to avoid increasing the difficulty of falling vines.
The fourth is to take more measures in the medium term and control the big leaves.
The measures taken at the seedling stage can be used for medium-term management. The particularity lies in the mid-term depression of the field, and the deterioration of ventilation and lightness, which aggravates the degree of large and thin leaves. After the vines fall, a large number of leaves are laid on the ground, and it is impossible to carry out photosynthesis, compete for nutrients, spread diseases, form a vicious circle, and it is necessary to remove the big leaves and old leaves at the bottom in time. Fertilizer management should eat less meals, do not use too much fat, watering too much at one time, to apply organic activation nutrition package Jiamei dividend, Hailibao and phosphorus, potassium, calcium package nutrition potassium, sea star At the same time, the leaves are sprayed with Jiamei brain white gold and gold spots to prolong the growth period and prevent premature aging. Once the internode is long and the leaves are large, it is necessary to spray hormone drugs to control the leaves within a suitable range to achieve high quality and high yield.
Through the above cucumber leaf adjustment technology and management measures, I hope to help the farmers. Here, Hui Nongwang Xiaobian reminds you that during the planting process, don't ignore the small problems they produce, and deal with them in time, otherwise they will Cause serious damage!
Concentrated extraction powder is a plant as raw material, in accordance with the need for the use of the extracted end product, after physicochemical extraction and separation process, directed to obtain and concentrate one or more of the active ingredients in the plant, without changing the structure of its active ingredients and the formation of the product. According to the extraction of plant components, the formation of glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc.; according to the different traits, can be divided into plant oils, extracts, powders, crystals and so on.
