Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to solve the problems in the process of preparation and use of traditional seed coating agents, using pesticides as the active ingredients of seed coating agents, which is not conducive to ecological and environmental protection, and limits its popularization and application in agriculture. A method for preparing a green non-toxic double-effect seed coating agent is disclosed. In the present invention, the leaves of Zanthoxylum bungeanum and Cinnamomum camphora are first crushed and then boiled, and the effective insect-repelling components are extracted with ultrasonic waves. Collect the bud tip after treatment, grind and centrifuge to obtain the supernatant, then use tung oil and peach gum to heat and mix it as a film-forming agent, and mix it with the concentrated solution and the supernatant to obtain a green non-toxic double-effect seed coating agent

example 1

[0017] Weigh 80g of Zanthoxylum bungeanum and 400g of camphor leaves in turn, wash them with deionized water for 3 times, evenly spread them in the sun, expose them to the sun for 5 days, collect the exposed Zanthoxylum bungeanum and camphor leaves, and pour them into a universal grinder. After crushing, pass through an 80-mesh sieve to obtain mixed powder; pour the above-obtained mixed powder into a beaker containing 1500 mL of deionized water, then transfer the beaker to a steamer, cook for 45 minutes at a temperature of 90 ° C, and then take advantage of the Heat the beaker into an ultrasonic oscillator, under the condition of 120W power, ultrasonically treat for 20min, suction filtration, remove the filter cake, collect the filtrate, and transfer the obtained filtrate into a rotary evaporator, under the condition of a temperature of 80 ℃, rotary evaporation Concentrate to 1 / 5 of the original volume to obtain a concentrated solution for use; weigh 400g of potatoes, put them ...

Abstract

The invention discloses a preparation method of a green and toxin-free double-effect seed coating agent and belongs to the field of preparation of seed coating agents. The preparation method comprises: firstly, crushing Chinese prickly ash and camphor tree leaves and cooking; extracting effective insect-prevention components with the help of ultrasound; carrying out extraction filtration and concentrating to obtain a concentrated solution; after carrying out germination treatment on potatoes, collecting shoot tips; grinding and centrifuging to obtain supernatant; heating and mixing tung oil and peach gum to form a film forming agent; mixing the film forming agent with the concentrated solution, the supernatant and the like, so as to obtain the green and toxin-free double-effect seed coating agent. By utilizing the effective components in the Chinese prickly ash and camphor trees and an extract in the shoot tips of the potatoes as disease-resisting and insect-prevention effective components, traditional pesticides are replaced, and the prevention and treatment effect is good; the ecological protection is facilitated, and the preparation method can be popularized and applied in agricultural production.

Description

technical field [0001] The invention discloses a preparation method of a green nontoxic double-effect seed coating agent, and belongs to the field of seed coating agent preparation. Background technique [0002] Seed coating technology is an advanced seed treatment technology, which has been vigorously promoted and widely used in agricultural production, and has achieved significant social, economic and ecological benefits. At present, there are few studies on the application and promotion of forestry seed coating, and the cultivation of forest tree seedlings is faced with the same seedling growth problems as agriculture, and the growth period of forest trees is longer and the sowing environment is more complex. It can improve the germination environment of seeds, improve the germination rate of seeds, prevent and control diseases and insect pests in the seedling stage, and promote the healthy growth and development of seedlings. It has broad application prospects in forest ...
