Choosing fertilizer to supplement organic matter

Organic fertilizer and chemical fertilizer are mixed and applied organic fertilizer, and chicken manure and pig manure can be selected. However, it must be noted that chicken manure or pig manure must be fully decomposed before use, so as to avoid problems such as burning roots or causing pests and diseases. However, organic fertilizer should not be applied continuously, and should be used in combination with chemical fertilizers. It can be mixed or applied by means of rotation.

Reduce the amount of chemical fertilizer, choose the full water-soluble quick-acting fertilizer to apply the full water-soluble quick-acting fertilizer, the nutrient is full, the content is high, the dosage is small, and the utilization rate is high. Under normal circumstances, the application of 4~5 kg per acre can be .

The application of biological fertilizers and biological fertilizers has the effect of relieving phosphorus and potassium. Although its nutrient content is small, it can release the fixed phosphorus and potassium in the soil for the absorption and utilization of vegetables, which can degrade salt damage and promote plant growth. The role. In order to ensure that vegetables absorb enough nutrients, it is recommended that vegetable farmers still use biofertilizers and compound fertilizers in rotation.

Choosing humic acid fertilizer humic acid fertilizer can increase the utilization rate of phosphorus and potassium and some trace elements in soil. Humic acid fertilizer has synergistic effect on phosphorus and potassium. On the basis of increasing the application of humic acid fertilizer, the amount of chemical fertilizer can be appropriately reduced, which can be reduced by about 1/3. The humic acid fertilizers commonly used in vegetable production include nitrohumic acid, ammonium humate, sodium humate, potassium humate, diammonium humate, and humic acid phosphate.
