Salviae miltiorrhizae planting method

Abstract

The invention discloses a salviae miltiorrhizae planting method. The method comprises the steps of field selection and preparation, seedling transplantation, field management and pest and disease prevention. Field management further comprises defloration management and water and fertilizer management. During defloration management, inflorescences of salviae miltiorrhizae are sheared off in the morning, at noon and in the evening in the squaring stage, initial flowering stage and full-bloom stage. During water and fertilizer management, base fertilizer is applied during field preparation, wherein the base fertilizer comprises organic fertilizer 3000-5000 t / hm<2>; 50-80 kg / hm<2> potash fertilizer is applied in the 15-20 leaf stage; 40-60 kg / hm<2> potash fertilizer and 25-35 kg / hm<2> phosphate fertilizer are applied every 30 days in the flowering stage and fruiting stage from June to September. By the adoption of the method, vegetative growth and reproductive growth are strictly controlled in the salviae miltiorrhizae growing process, the probability of root splitting is reduced, growth of the phloem of salviae miltiorrhizae is promoted, accumulation of effective constituents of the roots of salviae miltiorrhizae is improved, and then the rhizome quality of salviae miltiorrhizae is improved.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine planting, and more particularly relates to a high-yield planting method of salvia miltiorrhiza for preventing and treating root-knot nematode disease of salvia miltiorrhiza with high efficiency and environmental protection. Background technique [0002] Salviamiltiorrhiza Bunge is a perennial herb of the Lamiaceae genus Salvia. Its dried roots and rhizomes are used as medicine. It is a traditional bulk medicinal material in my country. Since the 1970s, Salvia miltiorrhiza has become the first choice for clinical treatment of coronary heart disease, angina pectoris, myocardial infarction and other cardiovascular diseases. At present, the demand for raw materials of salvia miltiorrhiza in the pharmaceutical market has increased sharply, and the wild resources of salvia miltiorrhiza have been severely damaged, which has exacerbated the contradiction between supply and demand of salvia milt...

Problems solved by technology

At present, the commonly used propagation methods of Salvia miltiorrhiza in production include root division propagation, cutting propagation and reed head propagation, etc. However, due to long-term asexual reproduction, the content of active ingredients in the planted Salvia miltiorrhiza is extremely unstable, and the phenomenon of infection with viral diseases leads to a decline in quality and yield. Seriously affected the development of clinical application and pharmaceutical industry

At the same time, in the process of artificial planting of Danshen, Yaonong pursued the yield of Danshen unilaterally and applied a large amount of nitrogen fertilizer, which caused the rhizome of Danshen to crack and affected the quality of Danshen
