Embodiment 1

[0013] Example 1: Preparation of pollution-free bactericidal herbicide

[0014] A kind of plant-derived nano-sustained-release oil suspension of Red Thistle, which is characterized in that it comprises the following parts by weight of raw materials: 10-20 parts of Eupatorium adenophorum, 10-20 parts of Tithonia, 10-20 parts of Red Thistle -20 parts, 20-25 parts of nano sustained-release carrier;

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

[0016] (1) Mix silicohydroxyapatite, calcite, and kaolin according to the mass ratio of 35-45: 15-18: 15-18, and add to the mixture of 230 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol The solution was stirred at 65°C for 60 hours, filtered, and washed with hot ethanol at 60°C for 3 times to remove excess dimethyl sulfoxide (DMSO), placed in a vacuum drying oven, dried at 60°C for 24 hours, ground and sieved , Get a modified compound;

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

Embodiment 2

[0020] Example 2: The test area is set in the potato test area of ​​the farm, the previous potato is grown, the soil type is black soil, the soil organic matter content is 5.3%, the pH value is 6.6; the test area is raked in autumn, harvested in spring, and ridged in spring, Fertilization in spring; 175kg of phosphoric acid, 160kg of urea and 125kg of potassium sulfate per hectare.

[0021] Each experiment has 3 treatments, 4 repetitions, and each plot area is 10m2. The experiment design is carried out according to a completely random design, where A: clean water blank control; B: compound carbendazim 800-fold dilution positive control; C: this The plant-derived pesticide of the invention is diluted with a 300-fold dilution and seed dressing.

[0022] Investigation content and data processing: Randomly select 30 samples from each plot, investigate before applying medicine and 30 days after sowing, record the number of diseased plants, and observe the emergence rate.

[0023] The tes...

Embodiment 3

[0024] Example 3: Fertilizer effect test effect

[0025] The field comparative test of the present invention has achieved obvious effects, and the main performance is as follows: it is rich in organic matter and humic acid, can improve the soil structure, mature the soil, and promote the improvement of soil fertility. Compared with other fertilizers with equivalent nutrients, crop yields increase by 20%. Formulate and coordinate crops to absorb nutrients, stimulate and regulate crop growth, reduce or reduce crop diseases and insect pests, and affect crop quality. Do not use or reduce the amount of chemical fertilizers, which will help protect the environment. Utilizing the porous structure of hydroxyapatite, the drug is absorbed in the internal grid of the carrier to achieve the purpose of slow release. Hydroxyapatite also has biodegradable properties. The resulting degradation products are phosphate ions and calcium ions. These elements can be re-absorbed by crops and will not...

Abstract

The invention relates to a tropic ageratum 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 plant-derived nano slow-release oil suspension of the red thistle and a preparation method thereof. Background technique [0002] Plants will encounter various pests and diseases during their growth in nature, especially fungal diseases. There are many types and serious diseases. For example, gold disease, red gold disease, black gold disease, etc. are common and difficult to control on many crops. Diseases have brought huge losses to agricultural production. They mainly occur in the tender seedlings, buds, shoots and other parts of crops. In severe cases, the leaves wither, curl, turn brown, and die. At present, a large number of chemical methods are used to prevent and control powdery mildew. The main domestic drugs used to prevent powdery mildew are methyl. However, the unity of medication and the particularity of chemicals for many years can easily...
