Herbicidal fertilizer for rice field

Abstract

The invention relates to the field of agricultural chemistry, in particular to herbicidal fertilizer for a rice field. The herbicidal fertilizer is prepared from, in percentage by weight, 0.015%-0.5%of a herbicide, 0.1%-0.6% of an aid and carrier fertilizer, wherein the aid is prepared from an emulsifier, a dispersant, a viscosity regulator and an organic solvent; the herbicide is prepared from afirst effective ingredient and a second effective ingredient, the first effective ingredient is penoxsulam; the second effective ingredient is any two of bispyribac-sodium, fenoxaprop-p-ethyl and clomazone. The effective herbicidal ingredients in the herbicide fertilizer adopt a combination manner of three different herbicides and have complementary advantages, the herbicide controlling spectrumis enlarged, and double effects of fertilizer and the herbicide are realized. The herbicidal fertilizer integrates the herbicide and the fertilizer, has double functions of weeding and fertilizer effects by combining the herbicide and a fertilizer carrier and is labor-saving, time-saving, effort-saving and cost-saving. With the combination of the aid, the herbicidal fertilizer has excellent thermal stability, high yield and good herbicidal effects.

Description

technical field [0001] The invention relates to the field of agrochemicals, in particular to a herbicide fertilizer for paddy fields. Background technique [0002] Rice is an annual grass plant, which is produced on all continents except Antarctica. Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Herbicides are widely used in rice fields to prevent rice production from being reduced due to weeds. Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, but also grasses, broad-leaved and sedges, etc. When the herbicide varieties are used alone, they all show certain defects and limitations. Reasonable compounding of herbicides is an effective method to improve the ...

Problems solved by technology

[0007] In traditional agricultural production, the application of pesticides and fertilizers in the crop cultivation mode are mostly operated separately, which is time-consuming and labor-intensive, and is not compatible with the development of modern high-efficiency agriculture. The development of "medicine fertilizer" products integrating medicine and fertilizer , complete two processes at the same time with one application, saving labor and time, which is the need of modern agricultural development

However, the quality stability and efficacy of existing medicinal fertilizer products need to be improved, so how to improve the efficacy and quality stability of medicinal fertilizer products has become a research hotspot
