天津市水稻机插秧现状、存在问题及改进措施

Status Quo,Problems and Improvement Measures of Rice Mechanized Transplanting in Tianjin City

2009年以来天津市水稻机插秧快速发展,2012年机插率超过50%。但受育秧期高温、低温、大风等极端气候多发,以及目前机插育秧方式简陋、育秧分散、管理水平低、水质含盐量高等因素影响,育苗坏秧、插秧死苗现象普遍。建议推广应用工厂化集中育秧、改进育秧技术、改善稻田水质等措施,保障机插秧水稻生产。

Rice mechanized transplanting developed rapidly since 2009,area of mechanized transplanting showed more than 50%.Because of extreme weather(like high temperature,low temperature,high wind,etc.),simple and crude mode of mechanized transplanting,disperse seedling place,low control level,high salinity in water,and so on,phenomenon like bad seedling and transplanting seedling death happened extensively.There are some suggestions which of promoting factory seedling,improving seedling technique,and improving rice field water quality for ensuring rice mechanized transplanting production.
