Description

Rice humic acid foliar fertilizer containing alkaloid and preparation method thereof

technical field

The invention relates to the field of foliar fertilizers, in particular to a rice humic acid foliar fertilizer containing alkaloids and a preparation method thereof.

Background technique

Fertilizer is a direct or indirect supplier of nutrients needed for crop growth, and has the function of improving soil properties and improving crop yield and quality. However, the effective absorption of ordinary fertilizer crops is low, and the fertilizer effect is slow. Excessive application of chemical fertilizers not only causes low soil fertility utilization rate, nutrient imbalance, soil compaction, but also causes environmental pollution, nutrient enrichment and other environmental problems.

In field pest control, traditional chemical pesticides have the advantages of being fast, efficient, broad-spectrum and suitable for large-scale industrial production. However, as time goes by, the disadvantages of chemical pesticides are gradually exposed, especially the typical resistance of chemical pesticides. The "3R" problems of (resistance), resurgence and residue (residue) have prompted people to look for alternatives to chemical pesticides, transforming from traditional organic chemical pesticides to environmentally harmonious pesticides. Many plants contain a large number of active secondary metabolites. The botanical pesticides developed with these secondary metabolites are often environmentally friendly, generally low in toxicity, high in selectivity, difficult to cause pest resistance, unique mechanism of action, and development costs. Low-level advantages, showing obvious ecological benefits, economic benefits and social benefits, are the preferred pesticide varieties for the production of new green and pollution-free agricultural products. The research and development of botanical insecticides is currently attracting attention.

Humic acid foliar fertilizers currently on the market, although meeting the nutrient requirements of rice, cannot inhibit the infestation of diseases and insect pests during the growth of rice.

Alkaloids (C ₁₀ H ₁₄ N ₂ ) are widely used insecticides in the world. They act on nicotinic acetylcholine receptors, interfere with the stimulation conduction of the nervous system of insects, cause nerve pathway blockage, and then cause neurotransmitter substances - Accumulation of acetylcholine, which leads to paralysis and eventual death of the insect. It has good insecticidal effects on aphids, borers, stem borers and other crops such as fruit trees, cotton, vegetables, rice, rice, etc., is easy to degrade, and is non-polluting and non-toxic to the environment.

Paretin has the functions of repelling, antifeedant, stomach poisoning and contact killing. It mainly acts on the digestive system of insects. It can bind to specific receptors on the plasma membrane of midgut cells, thereby destroying the structure of the membrane, causing intestinal perforation, and killing a large number of insects. die by water. Paretin acts not only on nerve and muscle nodes but also on muscle cells. It has strong toxicity to insect flight muscles and body wall muscles, and obviously destroys the plasma membrane and inner membrane cells of muscle cells. The main mechanism of action is unique, and it is not easy to produce resistance Medicinal properties.

Surfactant-fatty alcohol polyoxyethylene ether can not only increase the contact wetness between nutrients and rice leaves, but related studies have also shown that it can promote the absorption of boron, manganese and humic acid by rice leaves.
