Embodiment 1

[0013] Embodiment 1: the preparation of pollution-free fungicide herbicide

[0014] A matrine plant source nano sustained-release oil suspension, characterized in that it is prepared from the following raw materials in parts by weight: 5-10 parts of matrine, 10-20 parts of chrysanthemum, 10-20 parts of guayule , 10-20 parts of water hyacinth, 20-25 parts of nano slow-release carrier;

[0015] The preparation method of described nano sustained-release carrier is:

[0016] (1) Mix silicon hydroxyapatite, montmorillonite, and titanium dioxide according to the mass ratio of 35-45: 10-15: 10-15, add to 230 parts of dimethyl sulfoxide (DMSO) and 50 parts In the mixed solution of methanol, stir at 65°C for 60 hours, filter, and wash 3 times with hot ethanol at 60°C to remove excess dimethyl sulfoxide (DMSO), put it in a vacuum drying oven, and dry at 60°C for 24 hours, Grinding and sieving to obtain a modified compound;

[0017] (2) Mix 1 part of primary modified compound, 15 part...

Embodiment 2

[0020] Embodiment 2: the test area is located in the potato test area of ​​the farm, and the potatoes are made before, and the soil type is black soil, the soil organic matter content is 5.3%, and the pH value is 6.6; Spring fertilization; 175kg of phosphoric acid, 160kg of urea, and 125kg of potassium sulfate were applied per hectare.

[0021] There are 3 treatments in each test, 4 repetitions, each plot area is 10m2, and the test design is carried out according to a completely random design, wherein A: clear water blank control; B: compound carbendazim 800 times dilution positive control; C: this The 300-fold dilution of the botanical pesticide of the invention is used for seed dressing.

[0022] Survey content and data processing: 30 samples were randomly selected in each plot, investigated before the application of the drug and 30 days after sowing, recorded the number of diseased plants, and observed the emergence rate.

[0023] The test results show that the seedling em...

Embodiment 3

[0024] Embodiment 3: Fertilizer effect test effect

[0025]The field comparative test of the present invention has achieved obvious effects, and the main performances are as follows: rich in organic matter and humic acid, it can improve soil structure, mature soil, and promote soil to improve fertility. Compared with other fertilizers with the same nutrients, the crop yield can be increased by 20%. Formulate and coordinate the absorption of nutrients by crops, stimulate and regulate crop growth, reduce or reduce crop pests and diseases, and affect crop quality. Do not use or reduce the amount of chemical fertilizers, which is conducive to protecting the environment. Utilizing the porous structure of hydroxyapatite itself, the drug is adsorbed in the inner grid of the carrier to achieve the purpose of slow release. Hydroxyapatite is also biodegradable, and the resulting degradation products are phosphate ions and calcium ions. These elements can be reabsorbed by crops without...

Abstract

The invention relates to a matrine plant based nano slow-release oil suspending agent and a preparation method thereof. The suspending agent provided by the invention can be used for soil treatment after planting before seedling, and has the characteristics of farmland weed eradication and broad-spectrum sterilization. Compared with the prior art, the formulation provided by the invention has the characteristics of favorable weed eradication effect, high safety for environment and the like, and the weed can not easily generate drug resistance, thereby having wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of pollution-free fertilizers, and in particular relates to a matrine plant source nano slow-release oil suspension and a preparation method thereof. Background technique [0002] Plants will encounter various diseases and insect pests during their growth in nature, especially fungal diseases. There are many types and serious diseases. For example, gold disease, red gold disease, and black gold disease are common and difficult to control on many crops. Diseases have brought huge losses to agricultural production, and mainly occur in the tender seedlings, buds, shoots and other parts of crops. When severe, the leaves withered, curled, turned brown, and died. At present, a large number of chemical means are used for prevention and control. The main agents used for the prevention and treatment of powdery mildew in China are methyl. Harmful, and there are residues in a large amount, which are difficult to remov...
