机穴播能显著降低劳动强度,提高生产效率,节本增效,是水稻规模化和专业化生产发展的方向。为探索上海市浦东新区单季杂交稻在相同的肥水管理管理条件下,机穴播不同播种密度与产量之间的关系,以及与机插秧、人工撒播等不同栽培方式之间的比较。为合理确定单季杂交稻机穴播播种密度提供依据。
Machine-hole sowing can significantly reduce labor intensity, improve production efficiency, cost-effective, is the direction of large-scale and specialized production of rice. In order to explore the relationship between different sowing densities and yield of single cropping hybrid rice in Pudong New Area in Shanghai under the same management conditions of fertilizer and water management, as well as the comparison with different planting methods such as machine transplanting and manual sowing. In order to reasonably determine the single-season hybrid rice planting density seedbed provide the basis.
