摘要
以2010-2012年光明米业有限公司下属的崇明跃进基地‘武运粳23号'百亩丰产方和大丰海丰基地‘武育粳3号'千亩丰产方为研究对象,分别设人工撒直播、机条播、机插秧和机条播、旱直播、机插秧等种植方式,分析了水稻产量结构、投入产出等指标。结果表明:水稻不同种植方式的最终产量无显著差异,而在产出绩效方面,跃进基地机条播比机插秧平均增加效益21.33%,海丰基地旱直播比机插秧平均增加效益14.62%,生产方式更为简便的机直播稻优势明显。
During 2010- 2012 both 6.67 hm2 high yield plot of rice cultivar ＇Wuyunjing 23＇ on the Chongming Yuejin Farm and 66.67 hm2 high yield plot of rice cultivar ＇Wuyujing 3＇ on the Dafeng Haifeng Farm were used as objects of study,and their yield components and input and output indices were compared and analyzed respectively under artificial direct seeding, mechanical row seeding and mechanical transplanting as well as mechanical row seeding, direct seeding on dry paddy field and mechanical transplanting. The results showed that there were no significant differences in rice yield among different cropping patterns,while in terms of profit,the mechanical row seeding on the Yuejin Farm was averagely 21.33% higher than the mechanical transplanting,and the direct seeding on dry paddy field on the Haifeng Farm was averagely 14.62% higher than the mechanical transplanting. No doubt direct seeding simpler in cropping pattern had obvious advantages.
