Choosing fertilizers to supplement organic matter
In general, soil compaction and salinization are mainly due to large-scale application of chemical fertilizers and ignoring the application of organic fertilizers, which results in the decline of soil fertility and the resulting decrease in soil permeability. So you have to choose fertilizers cleverly:
Organic manure and chemical fertilizers are mixed and used for organic fertilizers. Chicken manure and pig manure can be selected. However, we must pay attention to chicken manure or pig manure must be fully cooked before use, so as not to cause burning root smoked seedlings or cause diseases and insect pests and other issues. However, organic fertilizers are not suitable for continuous application and should be used in combination with chemical fertilizers. They can be mixed and flushed, or alternately flushed.
Reduce the amount of chemical fertilizers, select all-water-soluble quick-acting fertilizers for flushing and applying water-soluble quick-acting fertilizers. The nutrients are full, high in content, low in usage, and high in utilization rate. Under normal circumstances, each flush can be applied for about 4 to 5 kg per acre. .
Bio-fertilizer bio-fertilizer has many functions of dissolving and dephosphorizing potassium. Although its nutrient content is small, it can release the fixed phosphorus and potassium in the soil for vegetable absorption and utilization, and it can degrade salt and promote plant growth. The role. In order to ensure that the vegetables absorb enough nutrients, it is recommended that the vegetable growers still use the biofertilizer and the compound fertilizer.
The selection of humic acid fertilizer humic acid fertilizer can increase the utilization of P and K and some trace elements in soil. Humic acid fertilizers have a synergistic effect on phosphorus and potassium. Based on the application of humic acid fertilizers, the amount of chemical fertilizers can be appropriately reduced, and generally it 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 humic acid, and phosphoric acid fulvic acid.
