Cultivating method for preventing anthracnose of sealwort

Abstract

The invention relates to the field of crop planting, in particular to a cultivating method for preventing anthracnose of sealwort. The cultivating method includes (1) selection of planting land; (2) treatment of sealwort seedlings; (3) planting of sealwort seedlings. Oleic-acid-modified sodium silicate contains a large amount of hydrophobic groups. The sodium silicate is mixed with plant essentialoil and metal-salicylic acid complex and then sprayed to a plant, not only the disease resistance of the plant can be enhanced, but also bacillus anthraci can be killed.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a cultivation method for preventing Polygonatum anthracnose. Background technique [0002] Polygonatum is the general term for the rhizomes of various plants of the genus Polygonatum in the family Liliaceae. Polygonatum, Polygonatum yunnanensis and Polygonatum multiflora recorded in the Pharmacopoeia of the People's Republic of China (2005 Edition) are their primary drugs. According to traditional medicine, Rhizoma Polygonatum has the functions of invigorating kidney and essence, nourishing yin and moistening dryness, and has been used for long-term treatment of kidney deficiency, weakness of spleen and stomach, lung deficiency and dry cough, and body fatigue and fatigue. In recent years, with the continuous deepening of the research on Polygonatum, the application fields of Polygonatum continue to expand. At present, artificial cultivation of Rhizoma Polygonatum has become the main...

Problems solved by technology

But sealwort cultivation is often invaded by leaf spot, black spot, and anthracnose. Among them, anthracnose is particularly significant, which seriously affects the yield and quality of medicinal materials. At present, most of them adopt the method of spraying pesticides to deal with it, but due to the excessive amount of pesticides sprayed In the soil, it not only pollutes the soil, affects the environment, but also reduces the production of plants

[0003] The application number is 201711369545.X, which discloses a cultivation method to prevent pests and diseases from biting Polygonatum seedlings, by burying the sterilized Polygonatum root in the soil covered with compound soil and hay, and setting a net around the soil And the container containing the medicinal liquid, the container and the net are integrated, and are located under the net, characterized in that the composition of the composite soil is recorded in parts by weight as follows: volcanic ash 10-20 parts, apatite powder 15-20 parts, chlorinated Potassium 5-8 parts, loam soil 30-50 parts, garlic boiled liquid 10-20 parts, compound soil can further supply nutrients to Polygonatum seedlings, and compound soil also has the effect of repelling insects, making Polygonatum massive roots germinate in the early stage to Before they grow into seedlings, they are protected from insect bites and the survival rate of cultivation is improved. However, the cultivation method requires a large amount of compound soil and changes the substances in the soil, which further leads to an increase in the cost of cultivation.
