Description
Technical Field
The invention relates to the technical field of special fertilizers for coptis chinensis, and particularly relates to a special fertilizer for coptis chinensis and a production method thereof.
Background
Coptis (Coptis chinensis Franch.) is a perennial herb of Coptis of Ranunculaceae, and its dried rhizome is a large precious Chinese medicinal material widely used for resisting bacteria and diminishing inflammation, and is widely used as a main raw material of Chinese patent medicines such as berberine, rhizoma coptidis tablet, Coptis chinensis Shuangqing pill, Coptis chinensis Shangqing pill, etc. The coptis chinensis prefers cold and humid environments, is forbidden to high temperature and direct strong light, has poor environmental adaptability, is mostly distributed in cold and high-altitude areas, and becomes a main economic crop for farmers in alpine mountain areas. Coptis root used as main Chinese patent medicine with broad-spectrum antibacterial and anti-inflammatory effectsThe traditional Chinese medicine composition has the advantages that the raw materials are needed, the market demand is high, the wild resources are exhausted due to long-term mining, and the market supply of the traditional Chinese medicine composition completely depends on artificial cultivation. As the coptis plants grow slowly, the formed commercial medicinal materials need to be planted continuously for more than 6 years, and in order to pursue high yield and economic benefit, coptis planting farmers often apply a large amount of chemical fertilizers as the main production management measures in the coptis planting process. The 'customary fertilization' method in the main production area of coptis is 'base fertilizer + top dressing': (1) base fertilizer, mu (667 m)2) Applying ammonium carbonate 50 kg/year and calcium superphosphate 75-100 kg/year; (2) and (3) topdressing, wherein the dosage of each mu of topdressing is 40-50 kg of ammonium bicarbonate, or 25kg of urea, or 40-50 kg of compound fertilizer (N-P-K is 15-15-15 is most common). The reason why ammonium bicarbonate and calcium superphosphate are used in large quantities is that the ammonium bicarbonate and calcium superphosphate are cheap and the fertilizer investment cost is low, and due to the reasons of cost and the defects of knowledge on formula fertilization and soil testing fertilization, farmyard manure or commercial organic fertilizer is rarely used, potassium fertilizer is basically not applied, and the fertilizer is used in a high-nitrogen high-phosphorus and potassium-free or low-potassium mode for a long time, so that the nutrient imbalance of soil is caused, the normal growth of coptis plants is not facilitated, the quality and the yield of coptis medicinal materials are difficult to guarantee, and meanwhile, the absorption and utilization rate of nutrients is low, so that the adverse effect is caused to the soil and the environment.
Because the growth cycle of the coptis chinensis is long, the coptis chinensis is mainly selected from low-cost ammonium bicarbonate or convenient urea during topdressing every year, in recent years, because of the popularization of compound fertilizers, the nitrogen-phosphorus-potassium ternary compound fertilizers are gradually increased as topdressings, and because the coptis chinensis plants are small, the planting density is as high as 9 thousands of plants/667 m2The stems and leaves of the coptis chinensis are dense after the coptis chinensis grows to the next year, the coptis chinensis can only be applied in a spreading mode during topdressing, the coptis chinensis is a negative plant and is particularly sensitive to burn caused by a chemical fertilizer, the coptis chinensis is easily damaged after directly contacting the chemical fertilizer, the stems and leaves are dead, and even the whole plant is dead due to fertilizer damage in severe cases, so that the production safety of the coptis chinensis is influenced. The topdressing of pesticide crops can be carried out only in sunny days when no surface moisture exists on the plants, fertilizer is spread and the fertilizer adhered to the leaves of the plants is knocked off to the ground in a 'stick knocking' mode, but the problem of fertilizer damage cannot be avoided, and the problem of fertilizer damage is asked when ammonium bicarbonate which is easy to absorb moisture is used for topdressingThe problem is more prominent, and the method becomes a practical production problem which puzzles the coptis chinensis planting farmers for a long time.
Therefore, a special fertilizer for coptis chinensis and a production method thereof are provided for solving the problems.
