摘要
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。
The seedling of hybrid lndica rice mechanical transplanting existed some problems of small seeding age elasticity, low seedling quality, badly transplanting injuring, slow seedling survival, etc. Those problems had limited the yield potential of hybrid Indica rice and ex- tension of mechanical transplanting technology. The study of mechanical seedling and transplanting technology of hybrid Indica rice had con- ducted 8 years continuously and summarized the balance cultivation technology regulations of hybrid Indica rice mechanical transplanting. These regulations make the technical indexes of varieties selecting, seedling, soil preparing, mechanical transplanting, yield and its compo- nents, the amount of fertilizer with different target yield, etc. The technologies of seedling, soil preparation, mechanical transplanting and field management were established.
