该项目从株型特征、生育表现、群体动态、营养平衡、地力建设、品种区试以及气候适应性等7个方面作7一系列的研究实践，形成7完整配套的吨粮田综合技术，在近年的生产实践中具有进步性和重演性。在栽培技术方面王要体现为“均衡增产、稀植、早促、淡水灌溉、提前晒田和控氮、安 The project has made a series of 7 research and studies in 7 aspects such as plant type characteristics, reproductive performance, population dynamics, nutrition balance, geotechnical construction, variety regional test and climate adaptability, forming 7 complete and complete sets of integrated technologies for the grain and grain fields. In recent years, the production practice is progressive and repetitive. Wang in cultivation techniques should be reflected as "balanced production, thin planting, early promotion, fresh water irrigation, in advance Shatian and nitrogen, security
