Embodiment 1

[0027] A plant-derived preparation capable of preventing and treating white and rust diseases, comprising the following raw materials: Phellodendron cortex and purified water, and the specific preparation method is as follows:

[0028] S1, drying: put the cortex in the dustpan, spread it out evenly, and dry it;

[0029] S2, cutting: cut the cork after drying into small pieces with a thickness of 5 millimeters, a width of 1 centimeter and a length of 1 centimeter;

[0030] S3. Mixing: Weigh 50 grams of small pieces of cork cork, place them in a beaker, then accurately weigh 1 liter of pure water with a measuring cylinder, pour them into the beaker, and obtain a mixed solution of cortex cortex and water with a concentration of ≥ 50 g / L:

[0031] S4, soaking: the concentration is 50g / L the cortex cortex and the water mixture solution standstill 1.5 hours, the cortex cortex is fully soaked;

[0032] S5, ultrasonic extraction: place the beaker with Phellodendron Phellodendri and w...

Abstract

The invention discloses a plant-source preparation for preventing and treating white and rust diseases and a preparation method thereof. The rust prevention and control agent uses the Chinese medicinal material Phellodendron Phellodendri as a raw material, and pure water as a solvent. The preparation process is to dry ≥ 50 grams again and make the same size Phellodendron cortex is placed in ≥ 1 liter of water, soaked and ultrasonically assisted in a water bath, then boiled on high heat and then fried on low heat, left to room temperature and filtered to obtain filtrate of Phellodendron cortex extract of ≥ 50g / L, which is the basis The invention provides a plant-derived preparation capable of preventing and controlling white and rust diseases. The invention has the characteristics of easy acquisition of raw materials, simple preparation process, short preparation time and the like. The anti-rust agent of the present invention is easy to be adsorbed on the surface of bletilla leaves, has good absorption effect, strong drug efficacy stability, green, no pollution, no residue, and no ecotoxicity, and the control effect on bletilla rust is as high as 92.15%. The incidence rate and disease index are only 17.68% and 3.99, which can effectively inhibit the incidence of white and rust, and play a good role in the prevention and control of white and rust.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of bletilla rust, and in particular relates to a plant source preparation capable of preventing and curing blight rust and a preparation method thereof. Background technique [0002] Bletilla striata (Thunb.) Reichb.f. is a perennial herb of the family Orchidaceae, and its dried tubers are used as medicine. Baiji is slightly cold in nature, bitter, sweet, and astringent in taste, and has the effects of stopping bleeding, reducing swelling, and promoting granulation. In addition, Baiji is also widely used in food, chemical and other industries, and it also has excellent ornamental value. With the further expansion of the development and utilization of Baihe in the market, it is difficult for the wild resources of Baiji to meet the increasing demand. Therefore, artificial cultivation of Baiji has been developed in a large area. [0003] With the continuous expansion of the planting ...
