Problems solved by technology

However, the new technology of no-tillage, seedling-free, and seedling-free has encountered the following insurmountable problems in the promotion process: one is that the wheat straw returned to the field is not easy to rot, and covers the surface of the soil, so that the germinated rice shoots cannot be touched. Second, wheat straw absorbs a large amount of available nitrogen in the field when it rots, causing a shortage of available nitrogen in the critical growth period of rice seedling and tillering, affecting the early growth and development of rice; The third is that compared with transplanted rice seedlings, rice seedlings are relatively weak when no-tillage intercropping is used, and they are at a disadvantage in competition with weeds, because under normal circumstances, weeds are better than crops in absorbing soil nutrients. For example, barnyardgrass absorbs about 45% more nitrogen than rice, and no-tillage facilitates the rapid occurrence and early damage of various weeds distributed in the plow layer or surface of the soil, causing serious damage to weeds in rice fields.
Therefore, it is difficult to popularize the new rice cultivation technology of straw returning to the field

Abstract

A herbiciding fertilizer able to speed up the erosion of wheat straw for rice field contains proportionally fertilizer component N+P2O5+K2O+Zn, bacterial component, and herbicide component.

Description

technical field [0001] The invention relates to a fast-rotten wheat straw weeding fertilizer for paddy fields which is used together with interplanting rice in wheat fields and can accelerate the decay of wheat straw. Background technique [0002] After the wheat harvest, the farmers are usually used to setting fire to the wheat straw scattered on the ground when the wheat is mechanically harvested, in order to grab the farming time, facilitate plowing and leveling the fields and other field operations and rice planting. Due to the relatively concentrated harvesting period of wheat, the scene of burning wheat stalks filled with flames and smog appeared everywhere in the vast rural areas. This practice not only wastes valuable agricultural natural resources, but also causes great pollution to the surrounding environment. At the same time, it also causes great hidden dangers to the normal traffic of adjacent airports, highways, railways and ports, which is not conducive to env...
