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。
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.
