摘要
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.
To explore a proper no-tillage cultivation technique for wheat, the L9 （3^4） orthogonal design with three factors and three levels was used to study the effects of planting pattern, coverage type and fertilizer rate on grain yield of the crop. The result showed that grain yield of wheat was highly significantly differ- ent among the treatments but was not significantly different between the treatments and the conventional tillage control. Grain yield was highly significantly different among planting patterns. The yield of the treatment in which 8 rows were planted in the obligate line was higher than that of the 2 treatments With 6 rows. Grain yield was significantly different among coverage types and was the highest in the farmyard ma- nure coverage treatment. Grain yield was not significantly different among treatments with different fertil- izer rates. The present study showed that compared with the conventional tillage, no-tillage cultivation did not significantly affect wheat grain yield. Therefore, it is concluded that suitable combination of planting pattern, coverage type and fertilizer rate can increase wheat grain yield.
