A bogey at random to change the light angle of the greenhouse: The angle of the solar greenhouse planted with cucumber is a long-term scientific demonstration. Its north-south span, height and angle of the back slope should not be arbitrarily changed.
Second, avoid concentration of fertilization when planting: a variety of chemical fertilizers, especially nitrogen fertilizer, in the high temperature and humidity, it will produce a large number of harmful gases, such as concentrated application in the planting ditch, will lead to cucumber roots die.
Three avoid bogey too deep: Now the melon farmers are using grafted seedlings for production, cucumber grafting is to resist disease, if the colonization is too deep, cucumber will give birth to reproductive roots, loss of grafting effect, can not reach the purpose of grafting disease prevention.
The four bogey rainy days do not reveal the grass: people often think that overcast, rain, snow, uncovering the grass, greenhouse temperature will drop, so do not exposing the grasshopper. In fact, the temperature will not only gradually decline, but also due to the long-term lack of sunlight in the cucumber, causing physiological disorders, severe cases will die.
Five avoid bogey nitrogen fertilizer in the winter: due to nitrogen fertilizer in the decomposition process, the water temperature will be greatly reduced, to promote the lower temperature, affecting the normal growth of cucumber pods.
6. Avoid using unripe organic fertilizers: Organic fertilizers will ferment very quickly in the presence of high temperatures. During the fermentation process, a large amount of ammonia will be produced. Lighter persons will decompose nitrogen fertilizers in the greenhouse, and most of them will poison all cucumber seedlings in the greenhouse.
Seven bogey noon, evening spray: at noon spray greenhouse temperature is too high, leaf water transpiration fast, the drug has not absorbed, it dried, especially manganese zinc drugs, 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 overslept: When the one-time fall and dwarf will cause the leaves to reduce light, affecting the normal growth of melons.
Nine bogey cucumbers and tomatoes in the same greenhouse cultivation: crops in the growth and development process, plants and roots will produce some secretions, which is a 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. Cucumbers and tomatoes are very susceptible to locust damage, once one party is harmed by locusts.
