The leaves of plants with physiological diseases are small, thin and yellow, and the roots are mostly black and yellow, and root rot is serious. At the same time, unreasonable application of a large number of elements during fertilization causes antagonistic effects between nutrients, affecting the absorption of nutrients by the grapes, and also causing pollution to the soil. In addition, it will affect the absorption of nutrients by the root system, resulting in the deficiency of trace elements, and the symptoms of deficiency will be shown on the leaves. Rational fertilization. A large number of elements are combined with trace elements, inorganic fertilizers are combined with organic fertilizers, and chemical fertilizers are combined with microbial fertilizers to achieve full-nutrient fertilization. Spray surface fertilizer. Avoid the flowering period, regularly spray the foliar fertilizer on a regular basis, according to the “Agricultural Resources Taobao Guideâ€, introduce the application of high-energy electrons and plant electronic polarity sensing principle by using the plant's own photosynthesis. Cell division, molecular synthesis and nutrient-matched digestion levels accelerate the frequency of metabolism, activate plant nutrient-sparing systems to produce more than fertilizer effects, and increase tree potential. Adding soil conditioner promotes root growth, improves soil aeration and soil pH, and promotes rapid formation of soil aggregate structure.
