Correct fertilizer and water management methods for vegetable planting in Yinchuan greenhouse

The key of Yinchuan vegetable greenhouse is artificial fertilization and water control, and the open-air vegetables basically depend on the weather to eat. Today, the small series of Bohan Agriculture talks about how to manage the fertilizer and water of greenhouse vegetable planting, and looks forward to helping planting friends.

First, after transplanting, it is necessary to control the application of fertilizer and water in Yinchuan vegetable greenhouse to promote its rapid greening and improve the survival rate of crops. When choosing fertilizer water, avoid its high concentration value, which will burn seedlings.

Second, the application of base fertilizer should be well controlled before the crops bloom to prevent the expansion of greenhouse construction in Yinchuan and the frequent application of human and animal manure.

Third, customers should pay attention to topdressing after the crops bear fruit. In order to promote crops to blossom more, bear more fruits and extract fruits quickly, so as to realize benefits and win excellent seasonal utility.

Yinchuan greenhouse has high temperature, long vegetable growth period and high yield, and needs a lot of fertilizer and water, which is different from outdoor vegetable growing with fertilizer irrigation. Generally speaking, the amount of fertilizer applied in greenhouse vegetable cultivation is higher than that in the open field. However, because the natural environment in the greenhouse is relatively closed, the volatile components after fertilization endanger the growth and development of crops, and long-term fertilization will cause problems such as salt accumulation and salinization in the soil layer in the greenhouse. Fertilization of greenhouse vegetables should not only consider the regulations of vegetable crops on chemical fertilizers, but also prevent the harm caused by excessive chemical fertilizers. One is the base fertilizer, supplemented by topdressing. Many people understand the necessity of greenhouse fertilizer and water management methods, but there are still some inadequacies in the operation process. The amount of base fertilizer should be determined according to different vegetable types and yields, and sufficient fertilization should be applied before planting or transplanting vegetables.

First, the frequency and dosage of topdressing should be determined according to the type and growth period of vegetables.

The second is to apply more organic fertilizer. Applying more organic fertilizer can improve the physical properties of soil layer, supplement various nutrients, and improve the buffering capacity of soil organic matter and soil pH value.

Third, it is forbidden to topdressing easily decomposed base fertilizer. Fertilizers such as ammonium bicarbonate are easy to decompose and release dioxide under the high standard of greenhouse, which is easy to cause damage to vegetable crops when the greenhouse is closed.
