Three fertilizers are indispensable for cucumber management in greenhouse

1. Apply more organic fertilizer. Organic fertilizer can not only provide various nutrients for the growth and development of cucumber, but also reduce soil bulk density, increase soil porosity and improve soil physical and chemical properties. Therefore, organic fertilizer plays an important role in the continuous high yield of cucumber, activating and improving soil. In production, 2500-3000 kg of pig manure or 5000 kg of soil manure should be applied per mu.

two。 Spray foliar fertilizer. The use of foliar fertilizer is generally spraying Zhuangguatiling in the peak period of melon, and the nutrients are sufficient in the early stage. After melon fruiting, the fertilizer needed is larger, and foliar spraying Zhuangguatiling can supplement the nutrients needed by the plant.

3. Application of biological fertilizer. Increasing the application of organic fertilizer and biological bacterial fertilizer and properly reducing chemical fertilizer is the inevitable choice for the production of pollution-free green food. 8 kg of high-quality organic biological fertilizer combined with new high-fat film is applied in the newly-built greenhouse to optimize the quality of water absorption, air permeability and light transmission of plants. Block disease and insect predation signals and weaken the transmission media, resist and defend against natural environmental disasters. Reduce pesticide toxins and improve the application effect of pesticides or fertilizers.
