At present, in many vegetable-producing areas, soil deterioration such as soil compaction and aggravation of salt damage is increasingly evident. Many vegetable farmers do not know how to solve? In general, soil compaction and salinization are mainly due to large-scale application of chemical fertilizers, ignoring the application of organic fertilizers, which results in the decline of soil fertility and the scarcity of organic matter, which in turn causes a decrease in soil permeability. Therefore, in response to the problems raised by vegetable farmers, when leaching with water, organic matter should be added to improve the utilization of fertilizers and reduce nutrient loss is the key to change.
First, organic fertilizer and chemical fertilizer are mixed and applied. Crushing organic fertilizer can choose farmyard fertilizer. However, it must be noted that farmyard manure must be fully cooked before it can be used, so as to avoid causing burning of rooted seedlings or causing diseases and insect pests. Organic fertilizers are also not suitable for continuous flushing. They should be used in combination with chemical fertilizers. They can be mixed or flushed or alternately flushed.
Secondly, reduce the amount of fertilizers and select all water-soluble quick-release fertilizers for flushing. All-water-soluble fast-acting fertilizer, full of nutrients, high content, small amount, high utilization, under normal circumstances, each flushing per acre 4 kg to 5 kg can be.
Again, increase the biological bacterial fertilizer. Bio-fertilizer has the effect of lysing phosphorus and potassium, although its nutrient content is small, it can release the fixed phosphorus and potassium in the soil for vegetable absorption and utilization, which can play a role in degrading salt damage and promoting plant growth.
Of course, the lack of trace elements in the soil is an important manifestation of soil degradation in recent years due to the repeated planting. Therefore, in the adoption of the above measures, attention should also be paid to the selection of rooting agents that can activate the soil and promote root growth.
