This product is mainly produced with microbial metabolites, photosynthetic super carbon and bee venom (also known as queen bee embryo) as the core technology, and high-activity humic acid as the carrier, using high-concentration double chelating technology.
1, what is continuous cropping (or continuous cropping obstacle)?
When crops of the same family or variety are planted in the same plot for more than two years, the phenomena of rotten roots, dead trees, stiff seedlings, rootlessness, low crop yield and poor quality appear.
2. Three manifestations of continuous cropping: dead trees and rotten roots; Poor growth and development; The output is low.
3. Four reasons for continuous cropping: malnutrition; Large amount of bacteria; Soil poisoning; Unbalanced fertilization.
Wan Mukang solved the problem:
1. Malnutrition: Long-term continuous cropping, unreasonable use of chemical fertilizers, resulting in imbalance of macro, medium and trace elements, serious abundance and deficiency, directly leading to low crop yield and serious diseases.
2. Large amount of bacteria: that is, serious soil-borne diseases, such as collapse, collapse, root rot, wilt, verticillium wilt, bacterial wilt, soft rot and other diseases caused by soil-borne bacteria. It has special effects on root rot of fruit trees, Fusarium wilt of melons and watermelons.
3. Accumulation of soil poisons: A large number of residues caused by herbicides and pesticides and poisons secreted by plants themselves can cause soil fertility degradation and hardening, underdeveloped crop roots and serious premature aging.
4. Soil hardening: Long-term unscientific and large-scale application of chemical fertilizers has caused serious imbalance of water, fertilizer, gas, heat and soil microbial flora, serious solidification failure of phosphorus, potassium and trace elements, damaged soil aggregate structure, poor permeability, low fertilizer utilization rate and underdeveloped crop roots.
5. Soil acidification: Long-term unscientific use of chemical fertilizers (especially nitrogen fertilizers) has caused serious soil acidification, and caused the lack of elements such as calcium, magnesium and boron, and at the same time caused bacterial diseases such as root rot and bacterial wilt.
6. Salinization: The phenomenon that a large number of chemical fertilizers are used and the plough layer is too shallow makes the fertilizer and salt on the surface of the soil deposit seriously, resulting in underdeveloped roots, stiff leaves, short plants, low yield and many diseases.
7. Physiological diseases: physiological diseases such as lobules, yellow leaves, rolled leaves, mosaic, stiff seedlings, stiff fruits, weak branches, cracked fruits, umbilical rot, and poor root development caused by crop malnutrition.
