Efficient cultivation method with mechanized ridge-cultured rice direct seeding

Abstract

The invention belongs to the technical field of rice planting, and discloses an efficient cultivation method with mechanized ridge-cultured rice direct seeding. A mechanized ridge culture direct seeding technology is adopted, and has the advantages of being simple and easy to operate, saving fertilizer, pesticides and cost, and being efficient and easy to popularize compared with a traditional seeding raising transplanting method; the efficient management of water in the field is convenient, and the problems in traditional direct seeding of rice are effectively solved that the seedling emergence effect is poor and large-area promotion is difficult; the efficient management of the water in ridge culture effectively alleviates the contradiction of crop stubbles in a rice field-upland field rotation mode and prolongs the appropriate planting period of the crops; the mechanized ridge culture method is adopted to achieve full and efficient return of crop straw, thereby being conductive to increasing the soil organic matter content, improving the soil fertility and the soil sustainable utilization capacity, and improving the agricultural ecological environment; the mechanized ridge culture direct seeding method greatly improving the water storage and drought resistance abilities, wherein the rice can be planted on ridges, fish, ducks and the like can be raised in furrows, the cost oftraditional ditching and the like is greatly saved, and the planting benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a high-efficiency cultivation method for mechanized ridge-planting rice direct seeding. Background technique [0002] Rice is one of the most important food crops in the world. The sown area of ​​rice in my country ranks second in the world. The area of ​​rice in the south accounts for more than 60% of the cultivated land in all provinces. The farming systems mainly include single-cropping rice, double-cropping rice, paddy and dry crop rotation, etc. , of which, the paddy and dry rotations account for about 70% of the paddy field area. At present, large-scale rice planting is dominated by traditional planting methods such as seedling transplanting, manual transplanting, throwing and machine transplanting, and the technology is relatively mature. However, with the large transfer of rural land and the reduction of rural labor force, the production cost of seedling...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: although the traditional seedling raising and transplanting technology is mature, the planting efficiency is low, the cost input is high, and the contradiction between crop stubble and concentrated water demand is prominent, especially after the moderate scale operation of land intensification, the contradiction Increasingly; traditional direct-seeding rice has high requirements for paddy field preparation, difficult field water management, poor emergence effect, low emergence rate, serious lack of seedlings, low ear formation rate, easy lodging, low yield and benefit, and is not conducive to large-scale promotion application
