First, rational use of chemical fertilizers. Fertilizers should be applied according to the fertility laws of vegetables, and the amount should be strictly controlled. At the same time, appropriate amount of water should be taken after fertilization to keep the soil moist and reduce the concentration of soil solution so as to avoid damage to vegetables caused by high concentrations.
Second, increase organic fertilizer. Organic fertilizers form organic colloids during the decomposed process, while organic colloids have strong adsorption capacity for cations. Since the cations are mostly colloidal, the cations present in the soil solution decrease accordingly, so that the concentration of the solution in the soil does not rise too high, which can effectively buffer the soil nutrient capacity and reduce the possibility of occurrence of fertilizer damage.
Third, take a layered application. Regardless of whether organic fertilizers or chemical fertilizers are used, it is recommended to adopt stratified application and full depth application. In order to achieve the full integration of soil fertilizer, evenly distributed in the cultivation layer.
In short, in order to avoid the damage of vegetables, scientific and reasonable fertilization methods are adopted to achieve the purpose of high yield, high quality and high efficiency of vegetables.
