Abstract

The invention relates to a machine-transplanted rice long-acting weed-closing and adverse-resistant green returning fertilizer granule, which comprises a compound fertilizer, an adhesive, a rooting agent, fulvic acid and a weed-closing agent. In the compound fertilizer, nitrogen, phosphorus and potassium are in a weight part ratio of 15:15:15, 15:10:10, or 19:7:14; the adhesive is pregelatinized starch, xanthan gum, sesbania gum, konjac gum, polyacrylamide, hydroxypropyl methyl cellulose, or carboxymethylcellulose; the rooting agent can be indoleacetic acid, indolebutyric acid, indole-3-butyric acid potassium, naphthylacetic acid or sodium naphthalene acetate; and the weed-closing agent can be butachlor, oxadiazon, pendimethalin, oxyfluorfen and the like. According to the invention, high polymer adhesive particles are prepared into a glue solution with clear water, compounding materials are crushed and then mixed evenly, and then the mixture is subjected to granulation molding by a double-roll extruding granulator, and the processing process is simple. The materials are prepared into dry granules that are rich in nutrients and can promote regulation, energy, and planting injury repair and the like, the granule are sprayed into rice field and become loose after water absorption. The granules provided by the invention can completely replace the fertilizers and herbicides produced by the traditional method.

Description

technical field [0001] The invention relates to the technical field of anti-grass nutrition and anti-adversity technology for transplanting crop seedlings, in particular to a machine-transplanted rice long-acting weed-sealing anti-adversity turning green fertilizer granule. Background technique [0002] Machine-transplanted rice usually uses plastic trays for seedling cultivation. The size of the plastic trays is 60cm×30cm×3cm, and the seeding rate is 3,000-8,000 grains. The claws of the high-speed rice transplanter are made of hard stainless steel, which can directly tear the blanket seedlings when transplanting. The plant injury of machine-transplanted rice seedling, especially the root system injury is comparatively serious thus. Excessive plant injury has seriously affected the growth of seedlings after machine-transplanted, which is the so-called slow seedling stage in agronomy. The slow seedling period is long, the tillering of rice plants is delayed, and the closure...
