Problems solved by technology

[0004] Comparing the above studies comprehensively, the shortcomings are: (1) The herbicide screening tests were all carried out at the seedling stage (pre-emergence to 5-leaf stage), and there was a lack of research on the entire growth period, especially the pre-emergence, post-emergence to ridge sealing stage , The herbicide research from the ridge sealing period to the pod setting period is not involved; (2) The relevant experiments only stay in the screening stage of the existing herbicides, and the research and development of special herbicides for alfalfa and field greens has not been reported; (3) The experimental treatment They are all single-sprayed, and no compound research has been carried out. In particular, the article "Test of Fourteen Chemical Herbicides on Weeds in Alfalfa Fields in Cangzhou Area" pointed out that "Gramina herbicides or broad-leaved grasses alone in the seedling stage of alfalfa sown in Cangzhou area Herbicides are not working well," but no solution is given
The shortcomings of current related research and application are: (1) When the two are used alone, the drug effect period is prolonged. Cyclohexenone herbicides generally kill weeds in about 10 days, and imidazolinone herbicides generally kill weeds in about 20 days. (2) The research on the mixed use of the two has not been reported or made public; (3) The dosage form of cyclohexenone herbicides is mainly emulsifiable concentrate, which causes serious environmental pollution; (4) The dosage form of imidazolinone herbicides is water Cyclohexenone herbicides are mainly herbicides, and the solubility of cyclohexenone herbicides is poor, and there is no research and development of mixed formulations
[0010] Comprehensively comparing the above studies, the shortcomings of the current research and development of biochemical fulvic acid are: (1) Although the fermentation process is relatively simple, there are fermentation microorganisms that are easily affected by the external environment, unstable activity, long fermentation time, low efficiency, and harmful Bacterial growth and other issues
(2) Although the currently disclosed oxidation method shortens fermentation 60d-90d to oxidation 18d-36d, there are still shortcomings such as complex equipment, cumbersome process, high energy consumption, high cost, and low efficiency.
(3) Although the fulvic acid prepared by the sulfuric acid acetone method has high purity, the preparation process is too complicated, and there are problems such as strong acid and strong alkali pollution and high equipment requirements
In addition, water-soluble carbohydrates, amino acids, proteins, sugar and acid substances, etc. are discarded, and the biological activity of the product is not as good as that of fermentation and oxidation.
(4) The finished fulvic acid is generally used in the currently disclosed herbicides, and the cost is high, and the application of biochemical fulvic acid in herbicides has not been reported or disclosed

Embodiment 1

[0045] The compound herbicide is composed of raw materials: 4wt% of biochemical fulvic acid, 4wt% of imazamox, 1wt% of clethodim, and 91wt% of auxiliary agent. Its preparation method is as follows:

[0046] (1) Naturally dry the edible mushroom residue or wood residue to a water content below 15%, and crush it to a particle diameter of 0.1-0.3mm; add 15wt% peroxide in 5 equal amounts according to the ratio of 1:3 (w / v) Hydrogen, and after adding hydrogen peroxide for the first time, add catalyst manganese dioxide according to the ratio of 20:1 (v / w), fully stir for 6-8h until the foam disappears; fully stand for more than 24h, and spray dry the liquid after solid-liquid separation , that is biochemical fulvic acid.

[0047] (2) Dissolve clethodim 1wt%, xylene 1wt%, Termul 2002wt%, Termul 12833wt%, butanol 1wt% into a homogeneous oil phase, add in the reactor with high-shear emulsifier; Tobacco 4wt%, biochemical fulvic acid 4wt%, polyvinyl alcohol 2wt%, ethylene glycol 5wt%, ...

Embodiment 2

[0059] A compound herbicide, the raw material composition is: biochemical fulvic acid 8wt%, imazamox 4wt%, clethodim 3wt%, adjuvant 85wt%. Its preparation method is as follows:

[0060] (1) Naturally dry furfural residue or xylose residue until the water content is less than 15%, and crush until the particle diameter is 0.1-0.3mm. According to the ratio of 1:2 (w / v), add 15wt% hydrogen peroxide in 4 equal amounts, and after adding hydrogen peroxide for the first time, add the catalyst manganese dioxide according to the ratio of 30:1 (v / w), stir well 6h-8h until the foam disappears. Fully stand for more than 24 hours, and after solid-liquid separation, the liquid is spray-dried to obtain biochemical fulvic acid.

[0061] (2) Add 3wt% of clethodim, 3wt% of xylene, 10wt% of PE 6400, and 5wt% of ethanol into a reaction kettle with stirring function, dissolve and mix to obtain a transparent oil phase; add 4wt% of imazamox, biochemical yellow Dissolve humic acid 8wt%, ethylene gl...

Embodiment 3

[0074] The compound herbicide is composed of raw materials: biochemical fulvic acid 5wt%, imazethapyr 4wt%, clethodim 5wt%, adjuvant 86wt%. The auxiliary agent is composed of: xylene 5wt%, Termul 2002wt%, Termul 12833wt%, butanol 1wt%, polyvinyl alcohol 2wt%, ethylene glycol 5wt%, organosilicone 0.05wt%, water balance. The preparation method is the same as in Example 1.

Description

technical field [0001] The invention relates to the field of herbicide preparation, in particular to the production of a compound herbicide suitable for planting turmeric and alfalfa in the Huanghuaihai region by using biochemical fulvic acid, cyclohexenone herbicides, imidazolinone herbicides and the like. Background technique [0002] Sinnabi and alfalfa are the main green manure feed crops planted in the Huang-Huai-Hai region at present. In recent years, driven by the adjustment of agricultural structure, the development of deep processing industry, the conversion of farmland to grassland and grassland crop rotation projects, the planting area has expanded year by year. However, affected by the layout and policies of the traditional planting industry, the production bases of alfalfa and alfalfa in the Huang-Huai-Hai region are mostly distributed in low-to-medium yield fields, coastal areas or areas along the Yellow Beach, where the soil is barren and weeds are serious. H...
