Embodiment 1

[0015] A method for interplanting no-tillage direct-seeding rice in a wheat field is characterized in that it comprises the following steps:

[0016] (1) In early and mid-June, 1-2 days before wheat harvest, sow rice seeds in the wheat field, and the amount of sowing per mu is 4-5kg;

[0017] (2) When harvesting wheat, the harvester is equipped with a straw crushing and throwing device, leaving wheat stubble and crushing the straw and randomly scattering it in the field to form a straw layer;

[0018] (3) After the wheat is harvested, flood it with water to make the soil saturated and the field water holding capacity is 0-20cm, drain the surface water in the field;

[0019] (4) Spray 160kg of NaOH solution of 3~6wt% concentration, 75kg of Jingzhongling aqueous solution of 2~5wt%, 35kg of sodium hypochlorite aqueous solution of 8~12wt% and 0.5~ 25kg of pretilachlor aqueous solution of 1.0wt% is uniformly covered and sprayed in the form of spray, and slaked lime powder is sprin...

Abstract

The invention discloses a wheat field interplanting no-tillage rice direct seeding method. The method is used for directly seeding rice after wheat is harvested. By adopting proper operation, a large amount of labor cost is reduced, the later use amount of fertilizer is reduced, the rice grows well, the yield is high, the organic matter content of soil is high, and meanwhile the occurrence of the phenomenon that wheat straw is incinerated after wheat is harvested is avoided.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for interplanting no-tillage direct-seeding rice in a wheat field. Background technique [0002] Rice is the main food that people like. Nearly half of the world's population feeds on rice. Due to the high and stable yield of rice, the perennial rice planting area in my country is about 450 million mu. Planting rice can relieve the population's pressure on the land and the demand for food. Planting methods are generally divided into transplanting, throwing and direct seeding. Transplanting is divided into manual transplanting and mechanical transplanting. Manual transplanting is labor-intensive and requires a lot of labor. With the increase in the proportion of rural labor going out to work, the cost of rice planting is getting higher and higher. Seedling transplanting can solve the labor problem in the transplanting process, but there are new problems such...
