为探讨小麦免耕栽培技术,采用三个因素三个水平正交设计L9(34),研究种植方式、覆盖物和施肥量对小麦产量的影响.结果表明:处理之间小麦产量差异极显著,但处理与对照产量的差异均不显著.种植方式之间产量差异极显著,预留行种植8行的产量极显著高于另外2种种植6行的产量;农家肥盖种的产量显著高于另外两种盖种的产量;施肥量之间产量没有显著差异.本研究说明免耕栽培不显著影响与小麦常规翻耕种植的产量,合理选择种植方式、覆盖物和施肥量可以增加小麦产量.
In order to explore the technology of no-tillage cultivation in wheat, three factors of three orthogonal design L9 (34) were used to study the effects of planting methods, covering and fertilization on the yield of wheat.The results showed that the yield of wheat was extremely significant, But there was no significant difference between the treatments and the control.The yield was significantly different among the planting methods, the yield of 8 rows of reserved lines was significantly higher than that of the other 2 kinds of planting 6 lines; The yield of the other two coverings did not differ significantly.This study showed that no-till cultivation did not significantly affect the yield of conventional tillage with wheat, and the reasonable selection of planting methods, cover and fertilizer could increase the yield of wheat.
