Compared with open field cultivation, greenhouse vegetable has stricter requirements on the quality and quantity of fertilizer. If improper fertilization, it will cause obstacles such as salinization, acidification and imbalance of nutrient ratio. In response to soil barriers in vegetable greenhouses, the following measures should be taken in fertilization techniques: Linyi Fertilizer Network Co., Ltd.

Add organic fertilizer. In particular, the application of coarse fiber with more fiber provides comprehensive nutrition for vegetables, enhances the buffering capacity of soil nutrients, prevents salt accumulation, and delays the soil salinization process. Linyi Fertilizer Network Copyright

After the vegetables are harvested, the soil is deeply ploughed. The topsoil rich in salt is turned into the lower layer, and the lower layer of soil with less salt is turned to the upper layer to reduce salt damage. Linyi Fertilizer Network Copyright

The film is removed by changing the gap, and the surface layer of the soil is leached to the deep layer by sun exposure or flooding. Linyi Fertilizer Network Copyright

Promote formula fertilization. Rational nitrogen, phosphorus, potassium and trace element fertilizers are applied according to the soil nutrient content, vegetable yield level and fertilizer requirements. It can not only balance soil nutrient balance, but also slow soil salinization and acidification. Linyi Fertilizer Network Copyright

Deep application of base fertilizer, limited fertilizer. The base fertilizer can be applied to the topsoil by ploughing, so as not to increase the salt content of the soil, and try to "snack more meals" when the fertilizer is topdressed.
