The present invention provides an amicarbazone-containing pesticide composition which is composed of active ingredients, additives, a solvent or a carrier. The active ingredients comprise two components, the first one is amicarbazone, the second one is one of glyphosate, MCPA sodium, ametryn, atrazine, diuron, and 2,4 D-butylate or a combination thereof; the active ingredients may also include any one of acetochlor, metolachlor or nicosulfuron. According to the invention, the combination of above pesticide ingredients not only can complement each other, but also expands an herbicide spectrum, and achieves significant synergies, improving herbicide effect. The pesticide composition of the invention has good safety on sugar cane, corn, and afterreap crops, has significant herbicide effects on evil weeds such as tribulus terrestris, brachiaria plantaginea, bermuda grass and cyperus rotundus, and has no the proneness of making weeds resistant to pesticide, and has broad prospects for agricultural promotion.

The invention provides a preparation method of a macroporous adsorbent resin for toxin substance adsorption, which comprises the following steps: preparing a lower-crosslinking-degree macroporous styrene-divinylbenzene resin, crosslinking the lower-crosslinking-degree macroporous styrene-divinylbenzene resin by a Friedel-Crafts process to obtain an ultrahigh-crosslinked-structure macroporous adsorbent resin, and introducing acylation reaction and grafting reaction in the ultrahigh-crosslinked-structure macroporous adsorbent resin preparation process to successfully prepare the carboxylic-acid-group-containing polyvinylpyrrolidone-grafted ultrahigh-crosslinking-degree macroporous adsorbent resin for toxin substance adsorption. The resin has the advantages of huge specific area and abundant pore structure, contains part of carboxylic acid ion groups, and is grafted by the polyvinylpyrrolidone on the resin surface. Therefore, the adsorption capacity for paraquat, acetochlor and other toxin substances containing cations or basic groups can be enhanced by utilizing the potential energy effect caused by hydrophobicity and huge specific area of the particular polystyrene skeleton of the ultrahigh-crosslinking-degree adsorbent resin, the pore screening action of the abundant pore structure and the charge action of the carboxylic acid groups. Besides, the polyvinylpyrrolidone is grafted on the resin surface to enhance the compatibility of the resin with blood.

The invention provides a maize machine direct sowing method under the condition of smashed wheat straw incorporation in the Shajiang black soil area. The method comprises the steps that wheat straw is harvested; the obtained wheat straw is smashed by means of a straw smashing device and then uniformly scattered, and covers the ground surface; base fertilizers with the nitrogenous fertilizer as a main is applied on the soil with the smashed wheat straw; maize sowing is conducted; after sowing or around stem pushing, ditching is conducted in an interlacing mode; 40% of Acetochlor Atrazine or 48% of ametryn and 50% of acetochlor and other or other weed killers are mixed with water for closed weeding; from the stem pushing period to the small horn mouth period of maize, nitrogenous fertilizer topdressing is conducted, and secondary nitrogenous fertilizer topdressing is conducted in the big horn mouth period. The inventor continually verifies and improves the method through field trials on different test field in nearly ten years, the results show that by means of the method, it can be ensured that the yield of maize is not affected in the wheat straw incorporation process, and even the yield is improved, and the greatest concern of farmers about reduction of the yield in the early incorporation stage is solved.

Aqueous herbicidal capsule suspensions of acetochlor, containing microcapsules of defined size, shell wall composition and thickness which contain acetochlor and reduced levels of herbicide safener are provided. The aqueous herbicidal capsule suspensions of acetochlor provide commercially acceptable weed control and selectivity in cereal.

The invention discloses a bacterium capable of degrading herbicide acetochlor and an application of the bacterium. The bacterium is mycobacterium sp. YCA11 and the preservation number of the bacterium is CGMCC (China General Microbiological Culture Collection Center) No. 7771. The mycobacterium sp. YCA11 with the preservation of CGMCC No.7771, disclosed by the invention, has the advantage that the degradation rate of the bacterium to 45mg / L acetochlor is up to 51.86% in 7 days in an inorganic salt culture medium, which indicates that the bacterium is capable of efficiently degrading the acetochlor and has a broad application prospect in the remediation of soil polluted by the acetochlor.

The invention discloses a chloroacetamide herbicide degrading strain, a bacterium produced thereby and application thereof. The chloroacetamide herbicide degrading strain, rhodococcus sp. AC-1, is preserved in China General Microbiological Culture Collection Center under CGMCC No.10778 on 30th April, 2015. The chloroacetamide herbicide degrading strain AC-1 is suitable for use in degrading chloroacetamide herbicides, preferably in degrading chloroacetamide herbicides in soil; by directly applying a degrading strain product, residue of the chloroacetamide herbicides (specifically alachlor, acetochlor and butachlor) in the soil can be decreased by above 85%, the problem that the residue of the alachlor, acetochlor and butachlor in agricultural production is out of limits is solved, and chemical damage caused by herbicide residue to crops is prevented.
