This product is mainly composed of microbial metabolites and bee venom (also known as queen bee embryo) as the core technology, high-activity humic substances as the carrier, and boron, zinc and photosynthetic carbon, which are the most scarce in China's soil.
Main problems to be solved in ten thousand mu continuous cropping agent;
1. Continuous cropping obstacle: When the same crop is 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. Malnutrition: Long-term continuous cropping and unreasonable use of fertilizers have caused imbalance and serious abundance and deficiency of major, medium and trace elements, which directly led to low crop yield and serious diseases.
3. Soil-borne diseases: diseases such as collapse, collapse, root rot, Fusarium wilt, verticillium wilt, bacterial wilt and soft rot caused by soil-borne bacteria. It has special effects on root rot of fruit trees, Fusarium wilt of melons and watermelons.
4. 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.
5. 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, destruction of soil aggregate structure, poor permeability, low fertilizer utilization rate and underdeveloped crop roots.
6. 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.
7. Salinization: The phenomenon that a large number of chemical fertilizers are used and the topsoil is too shallow causes serious accumulation of fertilizer and salt in the surface soil, resulting in underdeveloped roots, stiff leaves, short plants, low yield and many diseases.
8. Physiological diseases: lobules, yellow leaves and rolled leaves caused by crop malnutrition.
