【摘要】 2005年在江苏武进水稻超高产精确定量栽培攻关。试验实施前,针对武进试验点粳稻新品种武运粳7号生育规律、产量形成特性,根据当地的生态条件,运用精确定量栽培的技术原理,以产量800 kg/667 m~2为目标设计栽培方案,包括穗粒结构、播栽期、栽插基本苗数、氮肥用量与运筹比例等关键栽培技术进行了定量化设计,并在试验过程进行了严格的实施。结果表明,试验保证了武运粳7号超高产量潜力的表现,平均产量达803 kg/667 m~2。更多还原

【Abstract】 The field experiments for super-high yield precise quantity cultivation of japonica rice variety“Wuyunjing 7”were conducted at Wujin city,Jiangsu province in 2005.According to the local ecological condition,cultivation program with a yield goal of 800 kg/667 m~2,including spike-grain structure,date of planting and transplanting,seedling rate, nitrogen application rate and time,was designed based on the development law,yield formation characteristics of“Wuyunjing 7”.The program was implemented strictly throughout the experiments.Results showed that the potential of super-high yield of“Wuyunjing 7”were well presented and the ultimate average yield was as high as 803 kg/667 m~2.更多还原
