There are nine bogey in cucumber cultivation in winter greenhouse
A bogey at random changes the light receiving angle of the booth. The angle of the greenhouse in which cucumbers are grown is a long-term scientific demonstration. Its north-south span, height, and angle of the rear slope should not be arbitrarily changed. Second bogey concentrated fertilization when planting. All kinds of chemical fertilizers, especially nitrogen fertilizers, produce a large amount of harmful gases when they are hot and humid. If they are concentrated in planting furrows, they will cause the roots of cucumbers to die. Three bogey too deep. Now the melon farmers use grafted seedlings for production. The grafting of cucumbers is to resist disease. If the colonization is too deep, the cucumbers will give birth to regenerated roots and the graft will lose its function, which will not achieve the purpose of grafting and preventing disease. Four bogey rainy days do not reveal the grass. The vegetable growers often think that the temperature in the greenhouse will drop due to the rain, snow, and snow, and therefore the grass will not be uncovered. In fact, the temperature will not only gradually decline, but cucumber will also cause physical disorder due to long-term absence of sunlight, and in severe cases, dead seedlings will appear. Five avoid bogey nitrogen fertilizer in winter. Due to the decomposition of nitrogen fertilizer in the water, the water temperature will be greatly reduced, and the ground temperature will be reduced, affecting the normal growth of cucumber seedlings. Six bogey uses unripe organic fertilizer. Organic fertilizers will ferment quickly when exposed to high temperatures. During the fermentation process, a large amount of ammonia will be generated, and nitrogen fertilizers will be decomposed in the greenhouse, while the poisoning of all cucumber seedlings in the greenhouse will be caused. Seven avoid spraying at noon and evening. Noon in the spray greenhouse temperature is too high, leaf water transpiration faster, the drug has not absorbed, it dried, especially manganese zinc pesticides, but also cause phytotoxicity. Spraying in the evening is just the opposite of noon, because after the spraying, it is not completely absorbed by the cucumber leaves, and it will decompose and fail due to dampness, failing to achieve the purpose of treatment, but aggravating the occurrence of diseases. Eight bogey is too low. One-time fall and dwarf will make the leaves reduce light, affect the normal growth of melons. Nine bogey cucumbers and tomatoes in the same greenhouse cultivation. During the growth and development of crops, both plants and roots produce some secretions, which is a kind of plant instinct. The secretions secreted by cucumbers and tomatoes inhibit each other's growth and development. If they are cultivated in the same greenhouse, their growth and development will be severely inhibited, and the yield, quality and cultivation benefit of both parties will be reduced. It is specially used to draw this kind of ordinary insulin. The scale on the syringe is more accurate, because it needs to draw insulin according to 0.1ml or a finer scale, so its scale is relatively small.
