Which type of flush fertilizer is good for greenhouse planting? Please explain
Greenhouses should pay attention to choosing microbial flush fertilizers or fertilizers such as humic acid and fully water-soluble fertilizers, which both alleviate soil salinization and help raise ground temperature.
Choose biological fertilizers. Biological fertilizers can release the nitrogen, phosphorus and potassium fixed in the soil and promote the improvement of soil fertility. The effect of using biological fertilizers in old greenhouses is more significant. To ensure that vegetables absorb enough nutrients, it is recommended that vegetable growers use biological fertilizers and compound fertilizers in rotation.
Choose humic acid fertilizers. Because the soil in old greenhouses has relatively high levels of nutrients such as nitrogen, phosphorus and potassium, humic acid fertilizers can improve the utilization rate of phosphorus, potassium and certain trace elements in the soil. Humic acid fertilizers have a synergistic effect on phosphorus and potassium. On the basis of increasing the application of humic acid fertilizers, the amount of chemical fertilizers can be appropriately reduced, generally by about 1/3. Commonly used humic acid fertilizers in vegetable production include nitrohumic acid, ammonium humate, sodium humate, potassium humate, potassium nitrohumate, diammonium humate, humic phosphatic fertilizer, etc., which vegetable grower friends can choose to apply.
Choose fully water-soluble fertilizers. Fully water-soluble fertilizers are used in small amounts; only 10 to 15 jin is needed for one mu of greenhouse, while the utilization rate is as high as more than 85%. They can supplement the nutrients needed by crops. Used in rotation with biological bacterial fertilizer in winter, this is a flushing fertilization method worth promoting.
