Embodiment 1

[0053]The content of mefenacet is 0.19%, the content of bensulfuron-methyl is 0.01%; the content of macroelements N in fertilizer ingredients is 10% (from urea), P content is 5% (from monoammonium phosphate), and K content is 5% (from potassium sulfate ), the content of trace element zinc in the fertilizer composition is 0.1% (from zinc sulfate monohydrate), the content of boron is 0.1% (from borax); the content of polyvinyl alcohol in the slow release agent is 0.1%, the content of safener chlorpyridin is 0.05%, and the dispersion aid The content of corn starch is 0.5%, and the balance is kaolin as filler. Sprinkle the transplanted rice seedlings 7 to 15 days after transplanting, use 10 to 15 kg per mu, and keep a 3 to 5 cm water layer for 5 to 7 days after application, which can effectively control annual weeds in rice fields, such as barnyard grass and duck tongue Grass, sedge, etc. At the same time topdressing rice.

Embodiment 2

[0055] The content of mefenacet is 0.38%, the content of bensulfuron-methyl is 0.02%; the content of macroelements N in fertilizer ingredients is 15% (from urea), P content is 10% (from monoammonium phosphate), and K content is 5% (from potassium sulfate ), the trace element zinc content in the fertilizer composition is 1% (from zinc sulfate monohydrate), the boron content is 1% (from borax); the content of the slow-release agent gum arabic is 0.3%, the content of the safener chlorpyridin is 0.1%, and the dispersion aid corn The starch content is 1%, and the balance is filler kaolin. Sprinkle the transplanted rice seedlings 7 to 15 days after transplanting, use 5 to 10 kg per mu, and keep a 3 to 5 cm water layer for 5 to 7 days after application, which can effectively control annual weeds in rice fields, such as barnyard grass and duck tongue Grass, sedge, stephenia, goosegrass, etc. At the same time topdressing rice.

Embodiment 3

[0057] The content of benzsulfenamide is 4.75%; the content of bensulfuron-methyl is 0.25%; the content of macroelements N in fertilizer ingredients is 20% (from urea), P content is 4.5% (from monoammonium phosphate), and K content is 7% (from potassium sulfate ), the trace element zinc content in the fertilizer composition is 2.45% (from zinc sulfate monohydrate), the boron content is 2.45% (from borax); The starch content is 2.25%, and the balance is filler kaolin. Sprinkle in 7-10 days after throwing seedlings in paddy fields, use 500-1000g per mu, keep 3-5cm water layer for 5-7 days after application, mainly used for controlling barnyard grass, Yujiuhua, Tianjing in rice fields , cress and other weeds. It also played the role of topdressing rice.

Abstract

The invention discloses a herbicide medicine fertilizer for farmlands, which consists of weeding ingredients, fertilizer ingredients, a retarder, a safener, dispersing auxiliaries and filling materials. The fertilizer is characterized in that: the weeding ingredients comprise mefenacet and bensulfuron methyl; the fertilizer ingredients comprise nitrogen, phosphor, kalium, zinc and boron elements. The invention also discloses a preparation method of the medicine fertilizer. The medicine fertilizer granular formulation of the invention are applied to rice and one time use of the medicine fertilizer can realize both fertilization and weeding, thus reducing the labor intensity and working times of peasants and solving the problem that herbicide and fertilizer are needed to be applied for twice or a plurality of times under the conditions of the prior art. The medicine fertilizer of the invention effectively guarantees the scientific release of pesticides and fertilizers, prolongs the effective period of products, ensures the double effects of weeding and fertilization, has important significance for effective, scientific and reasonable use of resources and protection of environment and has positive boost to the investment reduction of users in agriculture and production and income increase in agriculture.

Description

technical field [0001] The invention relates to a medicinal fertilizer technology used in farmland, in particular to a medicinal fertilizer granule containing a herbicide and a compound fertilizer, and a preparation method and application thereof. Background technique [0002] Mefenacet is a selective systemic herbicide. It is mainly absorbed through the bud sheaths and roots, and is transmitted to the young shoots and young leaves of weeds through the xylem and phloem, preventing the growth point cell division and elongation of weeds, and eventually causing plant death. Strong selectivity to rice and high safety. It is suitable for controlling annual weeds in paddy fields. [0003] Bensulfuron-methyl is a selective systemic herbicide. It can rapidly diffuse in water, be absorbed by the roots and leaves of weeds and transfer to all parts of weeds, hinder the biosynthesis of amino acids, lysine, and isoleucine, prevent cell division and growth, and hinder the growth of wee...
