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。 Since 2009, the rice transplanter in Tianjin has witnessed a rapid development. In 2012, the machine insertion rate exceeded 50%. However, due to the extreme climate such as high temperature, low temperature and strong wind during the seedling season, the seedlings are poorly seedling and transplanting seedling under the influence of the primitive way of machine-transplanting seedling, scattered seedling, low management level and high salinity of water. Proposed to promote the use of factory-focused nursery, improve seedling technology, improve water quality and other measures to protect rice transplanting rice production.
