Second, the use of chemical fertilizers, directed improvement of the soil: vegetable gardens are not the same as acid and alkali, the chemical fertilizers used should also be different, otherwise the soil will acidify or alkalinize. Acidic soil should be modified with lime (30-40 kg per mu) or grass ash (40-50 kg per mu). It can also be modified with alkaline fertilizers such as ammonium bicarbonate, fluorine water, calcium magnesium phosphate and phosphate rock. If the soil is alkaline, it should be improved by using acidic fertilizers such as ammonium sulfate, ammonium nitrate, ammonium chloride, superphosphate, potassium dihydrogen phosphate, potassium chloride and potassium sulfate.
Third, rotation for intercropping, intercropping: tomatoes, peppers, eggplant, potatoes and other vegetables, such as continuous cropping, not only low yield, poor quality, and pests and diseases will become more and more serious, so the vegetable garden should be rotated to improve soil At the same time, it can also reduce the occurrence of pests and diseases and the accumulation of certain harmful substances in the soil. In addition, the practice of interplanting high and low plant intercropping in the vegetable garden is also a good way to improve the multiple cropping index, unit yield and overall benefit. In the process of land preparation, fertilization and field management, the vegetable garden has been matured and improved.
4. Protected cultivation: Vegetables are covered with film, which can not only produce high quality and high yield, but also mature and market early, which can effectively prevent rain erosion and soil erosion. In the vegetable gardens of hills, mountains and sloping fields, this can also make full use of the local light and temperature conditions to obtain higher yield and economic benefits.
