粳稻麦茬直播与自然生态匹配的运用与思考

Application of Natural Ecology Matching to Direct Sowing of Japonica Rice Following Wheat and Reflection

针对响水近几年粳稻麦茬直接播种栽培形式扩展态势,通过气象资料分析和田间调查,研究直播稻生理发育、高产要求、品种选择与自然生态环境的匹配关系,提出了响水地区生态条件下安全齐穗的时间节点及其生产实践对理论安全齐穗期的效果检验。

Through meteorological data analysis and field investigation in accordance with the current situation of direct sowing of rice following wheat of recent years in Xiangshui County, the physiological development of direct sowing rice, high-yielding requirement, variety selection and the matching relationship with natural ecology environment were studied and the safe full heading time was pointed out and the verification of theoretical safe full heading stage through rice production practice was demonstrated.
