Winter Cucumber "Six Changes" Promotes High Yield

The planting of thick seedlings was changed to reasonable and sparse planting. The winter temperature was low and the light was weak. The photosynthesis of vegetables was poor, and reasonable and sparse planting could produce high yields. Plants too dense will also win due to glory, resulting in reduced rate of sitting. Poor ventilation is easy to infect a variety of diseases, and the leaves are difficult to fight drugs. Once the disease spreads, it is difficult to completely cure.

The flat planting is changed to a ditch planting or a ridge planting ditch planting to dig the ditch on the flat land, and the seedlings planted on both sides of the ditch. Generally, the ditch depth is 30-35 cm. The ridges are planted in ridges and planted on both sides of the ridges, usually 20-25 cm high. In ridge or ditch planting, the smooth surface is large, which is conducive to the improvement of the ground temperature; the rhizosphere soil is good in air permeability, which is conducive to rooting, and can greatly enhance the plant's resistance to disease and stress, and the ability to continuously produce guarana; it is easy to control the fertilizer and water, so as to avoid water Injured roots, fat burning roots.

After easing the seedlings, irrigating the roots and preventing disease were used instead of applying pesticides and preventing diseases at the time of planting. In view of the serious situation of soil-borne diseases, many vegetable farmers used the method of irrigating the roots after planting the seedlings to prevent disease. Although this law has a certain effect, it is time-consuming and has short efficacy. Therefore, it can be changed to prevent disease by applying acupuncture at the time of colonization.

Cloudy colonization was changed to clear-sky colonization and cloudy planting. The light in the shed was weak and the humidity was high, which was not conducive to rooting. In the sunny days, although the seedlings were easy to wilt after planting, they were conducive to rooting and easing seedlings. In addition, the seedlings should be transplanted to the planting ditch or ridge by large, medium, and small grading. Judging from the entire shed, the big seedlings should be placed in the east and west of the shed and the front, and the saplings should be placed in the middle of the shed. Judging from one line, the big seedlings are in front, the seedlings are in the back, and the general seedlings are in the middle, which is conducive to the growth of the plants in the later period.

Fertilization is often changed to scientific fertilization. "Fertilizers are not in quantity, and they are sufficient for the road." The high yield of cucumber can not be separated from fertilization, but the more the fertilizer is applied, the higher the yield. The key is to apply what fat, how to use. The amount of fertilizer can not only be determined by the number of kilograms, but also depends on the composition and content of fertilizer. To apply scientific fertilization, it is not possible to apply fertilization blindly based on experience alone. Only in accordance with the characteristics of cucumber fertilizer and the specific conditions of fertilizer supply in each shed, scientific and rational selection of high-quality fertilizer, balanced and comprehensive fertilization can achieve high quality and high yield of cucumber.

Change the time to cover the plastic film In the past, people used to coat the cucumber after planting, or cover the plastic film immediately after planting. This is actually not conducive to the deep rooting of the grafted seedlings and reduces the ability of the plants to resist cold and bear low temperatures. Because the ground temperature during planting is still relatively high, it is not necessary to cover the membrane. After the planting, the deep rooting should be promoted as much as possible after planting, and then cover the mulch about 15 days after planting.
