Embodiment 1

[0014] A method for preparing a drying agent containing a surface active agent includes preparation of plant powder, plant extract preparation, and preparation of a drying agent. The specific steps are:

[0015] 1) Preparation of plant powder: take 5 parts by weight of Ginkgo biloba exocarp, 50 parts by weight of marigold, 10 parts by weight of neem, 20 parts by weight of Datura, 10 parts by weight of Artemisia annua, dry, coarsely crush to 60 mesh, and then Add a grinding aid to the plant powder at a weight ratio of 1000:0.001 and superfinely pulverize to obtain plant powder for use. The above-mentioned grinding aid is a mixture of glycerol and N,N-dimethylethanolamine with a weight ratio of 1:0.38 , The grinding aid can reduce the electrostatic adsorption and balling phenomenon formed during the ultrafine grinding process by adjusting the fluidity properties of the coarse powder and the surface electrical properties of the particles, and can reduce the recurrence of ultrafine pa...

[0019] A method for preparing a drying agent containing a surface active agent includes preparation of plant powder, plant extract preparation, and preparation of a drying agent. The specific steps are:

[0020] 1) Preparation of plant powder: Take 20 parts by weight of Ginkgo biloba exocarp, 20 parts by weight of marigold, 20 parts by weight of neem, 10 parts by weight of Datura, 20 parts by weight of Artemisia annua, dry, and coarsely crush to 40 mesh, then Add a grinding aid to the plant powder at a weight ratio of 1000:0.02 and superfinely pulverize to obtain the plant powder for use. The above-mentioned grinding aid is a mixture of glycerol and N,N-dimethylethanolamine with a weight ratio of 1:0.33 ;

[0021] 2) Preparation of plant extracts: add water to the plant powder at a material-to-liquid ratio of 1:12 (g / mL), ultrasonically extract for 30 minutes under the conditions of an ultrasonic temperature of 40°C and a power of 500W, and then at a temperature of 5°C, Centrifuge...

Embodiment 3

[0024] A method for preparing a drying agent containing a surface active agent includes preparation of plant powder, plant extract preparation, and preparation of a drying agent. The specific steps are:

[0025] 1) Preparation of plant powder: take 15 parts by weight of Ginkgo biloba exocarp, 35 parts by weight of marigold, 15 parts by weight of neem, 12 parts by weight of Datura, 13 parts by weight of Artemisia annua, dry, and coarsely crush to 50 mesh, then Add a grinding aid to the plant powder at a weight ratio of 1000:0.01 and superfinely pulverize to obtain plant powder for use. The above grinding aid is a mixture of glycerol and N,N-dimethylethanolamine with a weight ratio of 1:0.35 ;

[0026] 2) Preparation of plant extracts: add water to the plant powder at a material-to-liquid ratio of 1:10 (g / mL), and ultrasonically extract for 40 minutes under the conditions of an ultrasonic temperature of 45°C and a power of 480W, and then at a temperature of 4°C, Centrifuge for 20 mi...

Abstract

The invention discloses a method for preparing a tree trunk injection formulation with a surfactant. The method specifically comprises the following steps: drying gingko episperm, marigold, melia azedarach fruits, mandala and sweet wormwood, roughly crushing, adding a grinding aid, and performing superfine grinding so as to obtain plant powder; putting water into the plant powder, performing ultrasonic extraction, centrifuging, collecting an extract, putting water, cellulase, pectinase and fosfomycin into precipitate, performing enzymolysis, centrifuging after enzymolysis is completed, uniformly mixing collected enzymatic hydrolysate with the extract, and concentrating so as to obtain a plant extract; uniformly mixing the plant extract, emamectin benzoate, an emulsifier and water, therebyobtaining the tree trunk injection formulation. The method has the beneficial effects that the method for preparing the tree trunk injection formulation is low in cost and easy in industrial production, the prepared tree trunk injection formulation has relatively rich nutrient components such as insecticide active components, growth promotion active substances and minerals, is good in insecticideeffect and is capable of promoting healthy growth of trees.

Description

Technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a method for preparing a dry injection agent containing a surfactant. Background technique [0002] Pine Wilt Disease (Pine Wilt Disease), also known as Pine Wilt Disease or Pine Wilt Disease, is caused by Pine Wilt Disease Bursaphelenchus xylophilus (Pine Wood Nematode) is a devastating pine disease with strong pathogenicity and a long incubation period. Pine trees can wither and die within a few months after being infected. It is known as the "cancer" of pine trees. The disease host includes dozens of species of pines such as black pine, red pine and masson pine, and it also harms a few non-pinus coniferous trees. In my country, pine wood nematodes mainly harm masson pine and black pine. After the tree is susceptible, after the incubation period, the needles of the pine tree turn from green to reddish brown, especially in healthy pine forests. Pine wood nematode disease ...
