Summer and autumn vegetable fertilizer management essentials
Loose soil cultivating tillage soil combined with the application of active organic fertilizer can increase soil fertility and permeability, reduce plant growth potential, promote root down-barreling, reduce rot roots, and reduce surface salt damage caused by long-term fertilization of fertilization materials. Solanaceous vegetables often die from diseases such as root stem rot, wilt disease, verticillium wilt, and bacterial wilt. The application of organic humic acid liquid fertilizer can degrade the root salt damage and inhibit the disease. In addition, cultivating soil is conducive to the growth of the stem and prolong the result period.
Ginseng leaf nutrient sprayed with amino acid and humic acid foliar fertilizer can directly supply leaf nutrient, increase the accumulation of photosynthetic nutrients, and increase yield. Some farmers use high-nitrogen, high-potassium compound fertilizers, whether they are top-dressing or rush-fertilizer. In fact, the old sheds cultivated for many years have accumulated a large amount of inorganic salt, and only biological fertilizers (such as phosphorus lysis bacteria, potassium killing bacteria, actinomycetes, etc.) can decompose salt damage. Due to the high temperature and high humidity in the summer, the soil will have the phenomenon of rising salinity and returning to alkali. Therefore, bioorganic fertilizers must be applied topically or flushed.
