Embodiment 1

[0076] Mix butachlor and bensulfuron-methyl (19.2:1) to form 0.101%+16% (16-0-0) compound fertilizer (where nitrogen fertilizer is composed of urea:ammonium chloride=1:2) 99%+ Auxiliary 0.899% (containing 0.2% solvent (water), 0.2% stabilizer (composition of dipotassium hydrogen phosphate and 2,6-di-tert-butyl p-cresol), 0.4% diffusing agent nonylphenol polyoxyethylene Ether (NPEO), the ratio of 0.099% safener (the mixture of allyl dichloride and chlorpyramid), according to the following steps, produce the rice transplanting field pesticide herbicide fertilizer mixture of 0.101% bensulfuron-methyl-butachlor:

[0077] 1) Using water as a solvent, prepare a pesticide suspension mixture from bensulfuron-methyl technical material, butachlor crude oil, stabilizer, diffusing agent, safener, etc. according to technological requirements;

[0078] 2) Preparation of nitrogen-containing fertilizer granules: Put urea and ammonium chloride into the mixer in a ratio of 1:2 and mix with calc...

Embodiment 2

[0082] Mix butachlor and bensulfuron-methyl (19.2:1) to form 0.101%+23% (16-5-2) compound fertilizer (where nitrogen fertilizer is composed of urea:ammonium chloride=1:2) 99%+ Auxiliary 0.899% (containing 0.2% solvent (water), 0.3% stabilizer (composition of dipotassium hydrogen phosphate and 2,6-di-tert-butyl p-cresol), 0.3% diffusing agent octylphenol polyoxyethylene The ratio of ether (OPEO), 0.099% safener (the mixture of allyl dichloride and 2,4-D), produces the rice transplanting field pesticide herbicide fertilizer mixture of 0.101% bensulfuron-methyl butachlor, ( Step is identical with embodiment 1).

[0083] How to use the product: apply 20-25kg / mu of chemical fertilizer before rice transplanting (transplanting), and then sprinkle 20-25kg / mu of chemical fertilizer 5-10 days after transplanting, the total application amount of chemical fertilizer is 40-50kg / mu .

Embodiment 3

[0085] Mix butachlor and bensulfuron-methyl (19.2:1) to form 0.101%+28% (16-2-10) compound fertilizer (where nitrogen fertilizer is composed of urea:ammonium chloride=1:2) 99%+ Auxiliary 0.899% (containing 0.15% solvent (water), 0.3% stabilizer (composition of dipotassium hydrogen phosphate and 2,6-di-tert-butyl p-cresol), 0.35% diffusing agent nonylphenol polyoxyethylene The ratio of ether (NPEO) and octylphenol polyoxyethylene ether (OPEO), 0.099% safener (dichloroallylamine), to produce 0.101% bensulfuron-butachlor mixed pesticide and herbicide fertilizer for rice transplanting field Agent, (step is identical with embodiment 1).

[0086] How to use the product: 5-10 days after rice transplanting (transplanting), it can be evenly spread in the field, and the dosage is 20-30kg / mu.

Abstract

The invention relates to pesticide-weeding pesticide-fertilizer mixed agents having herbicidal activities for agricultural production. The pesticide-weeding pesticide-fertilizer mixed agents are made of bensulfuron-methyl and butachlor pesticide herbicide having herbicidal activities and nitrogenous fertilizers, and the agent is prepared from the raw materials of, with a total weight of the pesticide-fertilizer accounting for 100%: 0.005%-0.10% of bensulfuron-methyl, 0.096%-0.5% of butachlor, 10%-35% of nitrogen of nitrogenous fertilizers, 0.1%-0.5% a water solvent, 0.1%-3% of a stabilizer, 0.1%-3% of a dispersing agent and 0.05%-3% of a safener and the balance materials. The prepared pesticide-fertilizer mixed agents are applicable to transplanted rice fields, assist in fertilizing rice, turning rice green, tillering and weeding and can achieve purposes of labor saving, time saving and effort saving.

Description

technical field [0001] The invention relates to a mixture of pesticides, herbicides and fertilizers for transplanting rice fields, a production method and application thereof. Background technique [0002] In traditional agricultural production, the application of pesticides and fertilizer application in the crop cultivation mode are mostly operated separately, which is time-consuming and laborious, and is not compatible with the development of modern high-efficiency agriculture. Especially with the rapid development of my country's economy, migrant workers The number of farmers has increased, and the pace of transfer of rural labor to the secondary and tertiary industries has accelerated. The shortage of agricultural labor in many places has emerged. To develop a "medicinal fertilizer" product that not only has the efficacy of fertilizers, but also has the efficacy of pesticides, one application can complete two at the same time. It is the need for the development of modern a...
