【摘要】 通过对近几年机插秧生产实践进行调查总结,机插秧存在节省秧田、便于管理、省工节本、能有效解决杂草稻问题等优势,同时由于农民求简化、土地规模偏小不利于机插、机插育秧技术尚待完善提高、管理难以跟上等原因,机插秧推广缓慢;针对推广应用过程中存在床土培肥不高、播量不当、操作不规范、秧龄过长、机插秧缓苗期长、大田分蘖缺位多、栽插穴数普遍不足、肥水运筹不当、分蘖成穗率大幅下降等的技术问题,提出培肥床土、适量播种、精心培管、适时移栽、精细整地、科学灌溉、精确栽插、插好插足、科学肥水运筹等发展对策。更多还原

【Abstract】 The investigation of rice seedling transplanting by machine initiated that transplanting seedling by machine could save seedling nursery,be easy to handle,save cost and labor and control weedy rice.However,simplification in field management and small scale planting area are unfavorable to transplanting mechanization,which inhibits the extension of transplanting mechanization.Facing the problems such as low fertility of bed soil,incorrect sowing rate,abnormal operation,too-long leaf age,deficiency in tillers,inadequate hills,incorrect fertilizer and water management and large range decrease of productive tiller percentage,the relevant countermeasures are pointed out including increasing fertility of bed soil,sowing accurately,intensive management,transplanting in time and correctly and fertilizing and irrigating scientifically.更多还原
