直播稻是指在水稻栽培过程中省去育秧和移栽作业,在本田里直接播上谷种培育水稻的技术。按播种茬口可分为早稻直播、单季稻直播和连作晚稻直播三类。根据近几年大面积试种示范结果,直播稻的产量水平与同茬口移栽稻基本持平,一般直播连作早、晚稻亩产400公斤左右,单季晚稻直播亩产在500公斤以上。直播稻具有缓和季节矛盾,减轻劳动强度,省工节本、高产高效等轻型栽培技术特点,深受广大农户特别是种粮大户的欢迎,已逐渐成为水稻生产的重要栽培方式。
Direct-seeding rice refers to eliminating the need for nursery and transplanting in the process of rice cultivation, and directing the technology of cultivating paddy rice in Honda. According to sowing stubble can be divided into live broadcast of early rice, live-alone rice and even for late-season live broadcast of three categories. According to the demonstration results of large-scale pilot planting in recent years, the direct-seeded rice production level is basically the same as that of the transplanted rice at the same crop. Generally, the direct seeding continues to produce about 400 kg per mu for early and late rice and 500 kg per mu for single-season late rice. Direct-broadcast rice has the characteristics of light-cultivation techniques such as alleviating seasonal contradictions, reducing labor intensity, saving labor cost, high production and high efficiency, being popular with farmers, especially big grain growers. It has gradually become an important cultivation method for rice production.
