Second, the local cultivation of vegetables Newly converted vegetable fields, initially to plant vegetables with relatively low requirements for water and fertilizer, such as peas, mustard, onions and so on. After planting 1-2 è”¬èœ vegetables with relatively low water and fertilizer requirements, after the soil ripening degree is increased and the soil is melted, the vegetables with higher water and fertilizer requirements such as Chinese cabbage, tomato and cucumber are planted.
3. Reasonable rotation The correct rotation can not only make rational use of nutrients and water in the soil, but also give full play to the good effects of biological cultivation, fertilization and yield increase. At the same time, it can also reduce the occurrence of pests and diseases and promote high-quality and high-yield vegetables. In areas where conditions permit, it is possible to implement dishes, food, and crop rotation to improve the ecological conditions of the vegetable fields.
4. Formulated Fertilization In the process of applying chemical fertilizers in vegetable fields, it is necessary to pay attention to the reasonable combination of nitrogen, phosphorus and potassium fertilizers, avoiding the single application of nitrogen fertilizer, so as not to affect the good growth of vegetables and increase the harmful salts in vegetables.
V. Interplanting green manure In the conditioned areas, when planting vegetables in the vegetable fields, it can also be used as a short-term green manure. This will not only improve soil fertility, but also achieve organic combination of planting and land raising.
1. Adding fertilizer to soil and adding a large amount of fully decomposed organic fertilizer, supplemented by chemical fertilizer, can not only improve the agglomerate structure of the soil, but also allow the nitrogen in the organic fertilizer to be ammonium nitrogen, through the activity and decomposition of microorganisms. The nitrite nitrogen and nitrate nitrogen are sequentially decomposed, so that the microorganisms in the soil can absorb inorganic nitrogen and synthesize proteins. When the protein synthesized by the microorganism is decomposed, the produced nitrate nitrogen can be used as nutrients for the absorption and utilization of the vegetables.
