Embodiment Construction

[0015] 1. Production process:

[0016] 1. Preparation of 50% gramatan·Sclerotinia sclerotiorum water dispersible granules:

[0017] Weigh 35 kg of Sclerotinia sclerotium, 15 kg of grass-carb, 8 kg of NNO (dispersant), 1 kg of sodium dodecylbenzenesulfonate (wetting agent), 1 kg of starch (binder), ammonium sulfate ( disintegrant) 2 kg, light calcium carbonate (filler) 38 kg.

[0018] After mixing and stirring the above materials evenly, crushing and granulating to obtain 50% grass red · neat Sclerotinium water dispersible granules.

[0019] 2. Preparation of herbicide fertilizer:

[0020] Weigh 150 kg of urea, 100 kg of monoamine phosphate, 300 kg of potassium chloride, 0.04 kg of sodium selenate, 200 kg of 50% gramatan·Sclerotinia water dispersible granules and 150 kg of kaolin.

[0021] First, the above raw materials are crushed to less than 250 meshes, and then mixed evenly by a dust-proof mixer, and then the product is granulated to obtain the herbicide fertilizer.

Abstract

The invention discloses a weed-control medical fertilizer containing benthiocarb and sclerotium rolfsii, and relates to the field of fertilizers of the agricultural production technique. The weed-control medical fertilizer includes effective components and filler. The effective components are composed of urea, amine phosphate, potassium chloride, sodium selenate and 50% benthiocarb-sclerotium rolfsii water dispersible granules; the 50% benthiocarb-sclerotium rolfsii water dispersible granules include benthiocarb and sclerotium rolfsii, and the total mass of benthiocarb and sclerotium rolfsii is 50% of the total mass of the water dispersible granules. The weed-control medical fertilizer can solve the problems that weeds in a direct seeded rice field are difficult to prevent and kill off andlodging easily occurs. the yield of the direct seeded rice field can be improved, and the weed-control medical fertilizer can effectively improve the quality of rice.

Description

technical field [0001] The invention relates to the field of agricultural production technology fertilizers, in particular to the technical field of preparation of herbicide fertilizers. Background technique [0002] With the popularization and application of rice light cultivation technology, how to scientifically and accurately control weeds in rice fields and fertilize scientifically has become an important part of field management during rice growth. The annual economic loss caused by weed hazards in my country is more than 100 billion. The current means of controlling weeds mainly rely on the use of 100,000 tons of chemical herbicides because there are no biological herbicide products, and the area of ​​chemical herbicide use exceeds 1 billion mu. . As a result, a large number of chemical weeding has caused problems such as soil and water pollution, weed resistance, crop damage, and pesticide residues in agricultural products. Weed resistance alone leads to an annual i...
