Winter shed room planting cucumber nine taboo
One should avoid changing the light receiving angle of the shed. The angle of the solar greenhouse in which cucumbers are grown is long-term scientific evidence. Its north-south span, height and back slope angle should not be changed at will.
Two bogey concentrated fertilization when planting. A variety of chemical fertilizers, especially nitrogen fertilizers, produce a large amount of harmful gases when exposed to high temperatures and humidity. For example, concentrated application in the planting ditch will result in the burning of cucumbers.
The three bogey are planted too deep. Nowadays, melon farmers use grafted seedlings for production. Cucumber grafting is to fight disease. If the planting is too deep, cucumber will produce regenerative roots and lose grafting effect, which will not achieve the purpose of grafting and disease prevention.
Four taboos, rain, snow and snow do not reveal grass. People often think that the clouds in the shade, rain and snow are falling, and the temperature in the greenhouse will drop. In fact, the temperature will not slowly drop, but the cucumber will not see the sun for a long time, causing physiological disorders. In severe cases, there will be dead seedlings.
Five bogey in the winter a large amount of nitrogen fertilizer. Due to the nitrogen fertilizer in the process of decomposition, the water temperature will drop greatly, which will lower the ground temperature and affect the normal growth of cucumber.
Six bogey apply unfertilized organic fertilizer. Organic fertilizers will ferment quickly after high temperature. During the fermentation process, a large amount of ammonia gas will be produced. The lighter will decompose the nitrogen fertilizer in the greenhouse, and the heavy ones can poison all cucumber seedlings in the greenhouse.
Seven bogey noon, spray in the evening. At noon, the temperature in the greenhouse is too high, the leaves are transpiration fast, and the drugs are not absorbed, so they are dried, especially manganese-zinc drugs, which can cause phytotoxicity. In the evening, the spray is just the opposite of noon. Because it is not completely absorbed by the cucumber leaves after spraying, it will be decomposed and broken due to moisture, which will not achieve the purpose of treatment, but will aggravate the disease.
Eight bogey are too short. A short drop in the dwarf will reduce the light exposure of the leaves and affect the normal growth of the melon.
Jiuji cucumber and tomato cultivation in the same shed. It is well known that during the growth and development of crops, plants and roots produce some secretions, which is an instinct of plants. The secretions secreted by cucumbers and tomatoes have the effect of inhibiting growth and development. If the two are cultivated in the same shed, their growth and development will be severely inhibited, which will reduce the yield, quality and cultivation efficiency of both sides. Cucumbers and tomatoes are highly prone to mites, and once one is exposed to mites, another convenience can be quickly transmitted, causing serious harm. The temperature conditions required for the growth and development of cucumber and tomato are different. The two are cultivated together with the shed. The temperature management of the vegetable farmers cannot be taken care of by each other, so that the yield, quality and economic benefits of the two are reduced.
