杂交中籼水稻机插秧普遍存在秧龄弹性小、秧苗素质差、机械栽插植伤重、缓苗期长等不利因素,造成了机插水稻群体生育不平衡,严重限制了杂交中籼水稻产量潜力发挥和机插技术的推广。通过对江淮杂交中籼水稻机械化育栽技术连续8年的技术攻关,总结制定了杂交中籼水稻机插平衡栽培技术规程。该规程介绍了平衡栽培的定义,规定了长江中下游杂交中籼水稻机插的品种选用、育秧、整地、机插等技术指标、产量及其结构指标和不同目标产量施肥量,提出了平衡栽培的育秧技术、整地和机插技术和大田管理技术。
Transplanting medium indica rice transplanting generally has the advantages of small elasticity of seedling age, poor quality of seedling, heavy weight of mechanical planting and planting, long seedling period and other unfavorable factors, resulting in unbalanced growth of population of inserted rice and severely limited the yield potential of indica hybrid rice Play and machine inserted technology promotion. Through technical research on mechanized breeding of mid-season indica rice in Jianghuai for eight years in a row, the technical regulation of balanced cultivation of mid-indica rice in rice was concluded. The regulation introduces the definition of balanced cultivation, and provides the technical indexes, yield, structural indexes and fertilization amount of different target yield for selection, seedling selection, seedling raising, site preparation and machine insertion of medium indica rice in the middle and lower reaches of the Yangtze River. Seedling raising technology, site preparation and machine insertion technology and field management technology.
