Technical Field
The invention relates to the field of pesticides and fertilizers, in particular to a pesticide-fertilizer mixture applied to acid soil and a preparation method thereof.
Background
In agricultural production, fertilization and pesticide application are separated, the fertilizer and pesticide effects have no synergistic effect, and the pesticide-fertilizer mixture combines the fertilization and the pesticide application, so that the crop nutrition is improved, the crop growth function and the plant disease and insect pest capability are enhanced, the quality of agricultural products is improved, and the pesticide residue is reduced. In agricultural production, the labor intensity is reduced, the labor repetition is reduced, the rural labor force is saved, and the economic benefit is good.
In the structure of the papermaking raw materials in China, the grass raw materials account for about half, the wheat straws account for about 60 percent of the grass raw materials, the wheat straw pulping specific gravity is the largest, and the wheat straw pulping black liquor is always the main pollution source of the papermaking industry. The effective way for treating and comprehensively utilizing the black liquor of alkaline wheat straw pulp in the paper industry is alkali recovery, and because the straw pulp is short, thin and soft in fiber and is easy to compact, the pulp layer is dense, and the washing liquid is not easy to penetrate through the pulp layer for replacement during countercurrent replacement washing. Meanwhile, the black liquor has high silicon content, high viscosity, slow liquor drainage and low heat productivity, so that the alkali recovery treatment technology is difficult, and especially, the extraction of the wheat straw pulp black liquor has certain difficulty. Most of black pulping liquor in wheat straw factories is directly discharged into a receiving water body without being treated, so that the environment is seriously polluted, and the pollution treatment is urgent.
The wheat straw pulping black liquor, boric acid, magnesium sulfate and water-soluble potassium are reasonably compatible and combined to develop a pesticide-fertilizer mixture, most importantly, the black liquor is changed into valuables from waste, the environment is not polluted, nutrients can be provided for crops, the double effects of plant protection can be achieved, and the effects of two agricultural chemicals are exerted to the maximum extent; in addition, the product is convenient to apply, the labor intensity is reduced, and the labor and the time are saved. However, in the prior art, an effective mixing and using technology between the wheat straw pulping black liquor and boric acid, magnesium sulfate and water-soluble potassium fertilizer is not obtained, the problems of non-uniform dissolution, precipitation and stirring of the mixed liquid water-soluble fertilizer and the wheat straw pulping black liquor are not solved, and the mixing effect of the wheat straw pulping black liquor, the boric acid, the magnesium sulfate and the water-soluble potassium fertilizer is not known.
In patent CN108530220A, an eco-friendly pesticide-fertilizer mixture is disclosed, and its preparation method, wherein the pesticide-fertilizer mixture is obtained by using tung oil cake and sugar refinery waste liquid as raw materials, using sugar refinery waste liquid as binder, adding other additives for mixing, mixing uniformly, and granulating. The pesticide-fertilizer mixture has the advantages of simple preparation, good effects of inhibiting bacteria, killing pests and increasing fertilizer and wide market application prospect. The pesticide-fertilizer mixture has the effects of killing pests, inhibiting bacteria and supplying fertilizer, and has the characteristics of quick acting and long acting.
In patent CN107183085B, a preparation method of a rosin mixture biological medicinal fertilizer is disclosed, wherein rosin mixture biological pesticide is added into the fertilizer according to a certain mass ratio, and the rosin mixture biological medicinal fertilizer is obtained. The invention combines the fertilizer and the biological pesticide, so that the fertilizer has the effect of preventing and treating plant diseases and insect pests, and saves manpower.
In patent CN104529663B, a fertilizer-drug mixture special for litchi and a preparation method and application thereof are disclosed. The fertilizer-pesticide mixture special for litchi comprises the following components in percentage by weight: 0.05-0.2% of sodium octaborate tetrahydrate, 0.01-0.02% of ammonium molybdate, 0-0.02% of zinc sulfate, 0-0.02% of manganese sulfate, 0-0.5% of complexing agent, 0.008-0.01% of imidazole fresh, 0.128-0.16% of ethanol and the balance of water. The medium and micro fertilizer components in the fertilizer and pesticide mixture special for litchi have similar performance to those in an independent test solution and are not obviously affected by pesticides; the stability of prochloraz is improved. The special litchi fertilizer-pesticide mixture has good suitability under the condition of spraying immediately after mixing and good suitability under the condition of keeping away from light and heat for less than 3 days after mixing and storage, so the special litchi fertilizer-pesticide mixture can improve the fertilizer-pesticide spraying efficiency and save water resources and manpower resources, namely time cost.
Said invention lies in that it is a special-purpose pesticide-fertilizer mixture for non-acid soil, and is not applicable to most of acid soil. In addition, the huge amount of papermaking waste liquid is not effectively utilized, so that the waste is changed into valuables.
Through literature and patent search, the pesticide-fertilizer mixture prepared from cellulose, hemicellulose, acetic acid, uronic acid, lignin, silicon dioxide, alkali, boric acid, magnesium sulfate, water-soluble potassium and ethanol and the preparation method thereof are not reported in the literature at present, and related products are not seen in the market.
