单季晚稻“秀水04”作直播栽培已有多年历史,但其稳产高产的栽培技术未得到普及。因此,探索直播条件下“秀水04”高产、稳产的栽培技术和管理措施,是提高直播稻经济效益并得以推广的关键。下面就“秀水04”直播栽培时的播种、施肥、除草等项技术的探讨作一阐述。一、“秀水04”直播栽培时合理的产量结构及群体演变构成水稻产量的亩有效穗数、每穗实粒数、千粒重是植株各生育阶段个体发育与群体演变的最终结果。86年水稻收获期间对罗店解放村450亩直播稻中的播期相近,其余栽培因子相仿的“秀水04”直播稻
Single-cropping late rice “Silk 04” for direct seeding cultivation has many years of history, but its stable and high yielding cultivation techniques have not been popularized. Therefore, exploring the cultivation techniques and management measures of “Xiushui 04” with high yield and stable yield under the condition of direct seeding is the key to improve the economic benefit of direct seeding rice and promote it. The following on the “Xiushui 04” direct seeding cultivation of sowing, fertilization, weeding and other items of technology to make an elaboration. I. Reasonable Yield Structure and Population Evolvement of “Xiushui 04” During Direct Seeding Cultivation The number of effective panicles per panicle, grain number per panicle, and 1000-grain weight are the final results of individual development and population evolution in all growth stages of the plant. During the harvest of 86 years of rice, the sowing dates of 450 mu of direct seeding rice in Luodian Jiefang Village were similar to those of “Xiushui 04” with the same cultivation factors
