直播水稻就是指不经过育秧、移栽而直接将种子播于大田的栽培方式。相对于传统的育苗移栽,可节省大量劳力,减少秧田占地,在一些劳力不足地区,可缓解劳力季节性紧张。从理论上讲,直播稻具有生育期缩短、分蘖节位低而早、确保种植密度获较高产量等优势,但在一些地方的生产实际中表现却不是太好。一般认为,直播稻茬口要求严、技术要求较高,生产风险大。主要表 Direct broadcast of rice refers to the seedlings planted in the field without planting seedlings, transplanting and planting methods. Compared with the traditional seedling transplanting, it can save a lot of labor and reduce the area occupied by seedling. In some areas with insufficient labor, it can alleviate the seasonal tension of labor. In theory, direct-seeded rice has the advantages of shortened growth period, low and early tiller node, high yield of planting density, but not so good in some places. Generally believed that direct seeding stubble strict requirements, higher technical requirements, the risk of production. Main table
