Problems solved by technology

[0004] However, compared with transplanted rice, direct-seeding rice has three major problems: hard seedlings, heavy weed damage, and easy lodging
However, the use of film is not easy to degrade and cannot prevent the growth of weeds

Abstract

The invention discloses an embedded degradable film direct-seeding system for crop direct-seeding and application, and relates to the technical field of agriculture. The system comprises a degradablebottom film layer and a degradable cover film layer; the degradable cover film layer covers the degradable bottom film layer; and a seed adhesive is arranged in a seed adhesive area on the upper surface of the degradable bottom film layer. By means of the system in the invention, the rice growth cycle is shortened; the use of herbicides is reduced; the growth of weeds is limited; therefore, rice grows uniformly; and the process is simple and easy for popularization.

Description

technical field [0001] The invention relates to the field of agricultural technology, and more specifically relates to an embedded degradable film direct seeding system and application for direct seeding of crops. Background technique [0002] Direct seeding of rice is a cultivation method that directly sows seeds in the field without raising seedlings and transplanting. Large-scale direct seeding of rice can save a lot of labor and alleviate the contradiction of labor seasonal tension. It is of great significance to realize light, professional and large-scale rice production, and has broad prospects for promotion. [0003] Rice live broadcast has the following advantages: First, it saves labor and effort. Live broadcasting eliminates traditional seedling raising and transplanting labor, and saves seedling fields, making rice production simple and easy. The second is high output. Because direct-directed rice is more conducive to low-node tillering, the panicle stem is opt...
