Seminal root treating method for effectively controlling diseases of Pseudostellaria heterophylla

Abstract

The invention discloses a seminal root treating method for effectively controlling diseases of Pseudostellaria heterophylla. The method comprises steps as follows: roots of Pseudostellaria heterophylla plants having high disease resistance are selected as Pseudostellaria heterophylla seeds, after seminal roots of Pseudostellaria heterophylla are dug out from October to November, the seminal roots are placed in a shady, cool and ventilated place to be aired for 15-20 days, and the seminal roots are planted after 30%-40% of the seminal roots are shrunk; field permeability is improved, water and fertilizer management is enhanced, and unobstructed irrigation and drainage are kept; a 800-time diluent of Baitai, a 1,500-time diluent of 30% metalaxyl-M*hymexazol and a 1,000-time diluent of organic root flourishing water-soluble fertilizer are mixed and evenly sprayed to bodies of the Pseudostellaria heterophylla and planting ridge surfaces, then soil covering is performed, and the soil covering thickness is 6-8 cm. With the adoption of the method, the diseases of the Pseudostellaria heterophylla can be effectively controlled, the control effect can reach 85%, and the method is simple to operate and lower in cost and has the economic benefit.

Description

technical field [0001] The invention relates to a seed root burying method for effectively preventing and controlling diseases of heterophylla, belonging to the technical fields of plant protection and traditional Chinese medicine cultivation. technical background [0002] Pseudostellaria heterophylla (Mip.) Pax is the dried root of Pseudostellaria heterophylla (Mip.) Pax, which has the effects of nourishing qi, invigorating the spleen, promoting body fluid and moistening the lungs. As the wild Pseudostellariae suffers from predatory excavation, resources are becoming increasingly depleted. Today, Pseudostellaria Pseudostellaria is used in the production of clinical formulas of traditional Chinese medicine, Chinese patent medicines, and health care medicines all come from cultivated resources. At present, Shandong, Anhui, Jiangsu, Fujian, and Guizhou are the relatively large production areas for Pseudostellariae Pseudostellaria in China. Among them, the resources produced in...

Problems solved by technology

The disease is serious under the conditions of heavy rainfall, extensive management, and poor plant growth. The plants grow slowly in the diseased plots, and the fleshy roots are thin and thin, with low yield and poor quality, which poses a serious threat to the production of heterophylla.
