Planting method for improving yield and quality of continuously cropped red-rooted salvia

Abstract

The invention provides a planting method for improving yield and quality of continuously croppedred-rooted salvia. The planting method comprises the following steps: land selection, soil preparation, seedling transplantation, field management, harvesting and soil preparation after harvesting, wherein the field management specifically comprises intertillage and earthing up, topdressing, watering and later growth stage management, the later growth stage management refers to: in the period from the end of September to the middle of October, ditching is performed between lines for application of special fertilizer every five days, the special fertilizer comprises 20 parts of wheat seeds, 50 parts of humus soil and 50 parts of sandy soil, and 400kg of potassium hydroxide and 1600kg of clear liquid dung are applied per mu; the soil preparation after harvesting specifically refers to: the overgroud part of red-rooted salvia is cleared, then plowing is directly performed to directly turn wheat seedlings which already emerge into underground, the plowing depth is 40-60cm, and finally land is rolled by a stone roller and kept to be rolled till the winter is over. The method has the advantages of simple steps, easiness and convenience in operation, implementation of continuous planting of the red-rooted salvia on the same land, and improvements in the yield and the quality of the continuously cropped red-rooted salvia.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine cultivation, in particular to a planting method for improving the yield and quality of continuous cropping salvia miltiorrhiza. Background technique [0002] The traditional Chinese medicine Salvia miltiorrhiza (also known as blood ginseng, purple salvia miltiorrhiza, red salvia miltiorrhiza, etc.) is the dry root and rhizome of the perennial herb Salvia milti-orrhiza Bge. of the family Lamiaceae.

Modern medical research shows that Salvia miltiorrhiza has excellent curative effects on diseases such as coronary heart disease, hyperlipidemia, hypertension, myocardial infarction, cerebral infarction, and vasculitis. Tanshinone IIA and salvianolic acid B are the main active components of Danshen, with high cont...

AI Technical Summary

Problems solved by technology

[0003] In the current conventional cultivation method of salvia miltiorrhiza, it is impossible to plant salvia miltiorrhiza for two consecutive years in the same plot, so the planting area of ​​salvia miltiorrhiza is decreasing year by year

Moreover, the diseases of continuous cropping Danshen are serious, especially the occurrence of apical nematode disease, which affects the yield and quality of Danshen, and the content of tanshinone IIA and salvianolic acid B is greatly reduced.
