Due to the cultivation of vegetables for many years, the garden soil is aging, the soil strength is decreasing, the pests and diseases are serious year by year, and the economic benefits are reduced. The following measures should be taken to improve the old vegetable fields.
First, increase farm fertilizer, improve soil fertility Practice proved that the annual application of chemical fertilizers, not only high production costs, but also make the soil compaction, loss of fertilizer and fertilizer supply capacity. The base of vegetable gardens must be farmed with fertilizers. Soils should be improved to increase humus, so that factors such as water, fertilizer, gas, heat and bacteria in the tillage layer can be harmonized and unified. This creates an excellent environment with suitable temperature, humidity, and complete fertilizer for the growth of roots, stems and leaves of vegetables.
Second, the use of chemical fertilizers, directed to improve the vegetable garden due to acid and alkaline is not the same, the chemical fertilizers used should also be different, otherwise it will make it more acidic or alkaline. Test strips can be used to determine soil pH. If the test paper is pink or red in its soil solution, it is acidic; if it is blue or dark blue, it is alkaline. Alkaline soil should be improved with lime (30-40 kg per mu) or plant ash (40-50 kg per mu) to make it into a near-neutral soil.
Third, crop rotation, intercropping intercropping practice has proved that tomatoes, peppers, eggplant, potatoes, beans, peas, beans, melons, etc., such as year after year of continuous cropping, not only low yield, poor quality, but also more serious pests and diseases . Therefore, vegetable gardens need to implement different crop rotations to improve the soil and avoid the lack of an element in the soil (because the same kind of vegetables, the fertilizer elements are the same), but also can reduce a certain Severe occurrence of pests and diseases and accumulation of certain harmful (toxic) substances in the soil.
