1. Site selection and construction The vegetable garden should choose plots with flat terrain, sufficient sunshine, good water supply and convenient transportation. For low-lying areas, the drainage ditch should be excavated to improve the irrigation and drainage conditions of the land.
2. Change the soil and increase the fertilizer according to the soil quality of the vegetable garden, and use the soil method to change the soil. For soils that are too heavy, appropriate sand, garbage, and river sands should be modified; for those sandy soils with poor fertilizer and poor water retention, clay should be used for improvement. After the garden is selected, it is necessary to apply farmyard manure containing a large amount of organic matter to improve the fertility of the plot. Generally, 5000-10000 kg is applied per mu per year. The method of fertilization is to spread evenly, then plow it and mix it thoroughly with the soil. In the early years of the construction of the park, it is best to interplant green manure to accelerate the fertilization of the plot.
The vegetable garden not only requires high fertility, but also requires deep soil layers. Generally, the cultivated soil layer is shallow, not more than 15 cm, and there is a very hard plow bottom layer, which does not meet the soil requirements for vegetable growth. After changing to a vegetable garden, it is necessary to use deep ploughing to deepen the ploughing layer and mature it. The soft layer of soil can reach 30-50 cm.
3. Fertilizer application of vegetables is much higher than that of Daejeon, and there are many types of fertilizers required. In addition to satisfying nitrogen, phosphorus and potassium, the demand for trace elements in calcium and magnesium is also large. When applying chemical fertilizers, avoid applying single or multiple nitrogen fertilizers. In the land lacking calcium and magnesium, it is necessary to apply calcium fertilizer and magnesium fertilizer, or apply fertilizer containing calcium and magnesium, such as calcium magnesium phosphate fertilizer, calcium superphosphate, potassium magnesium sulfate, boron magnesium fertilizer and the like.
4. The mouth of the mouth is arranged in the early stage of the construction of the garden. It is best to plant vegetables with low requirements for water and fertilizer, such as peas, onions and cabbage. After a few years of planting, the degree of soil ripening is improved, and the water, fertilizer, gas and heat conditions are fully improved. Tomatoes, cucumbers, Chinese cabbage and other vegetable varieties that require higher soil fertility are planted.
