摘要
通过野外大田试验,研究了不同覆盖措施对春小麦生长及产量的影响。结果显示:覆盖处理春小麦的株高、叶面积指数、地上生物量均大于无覆盖对照(CK)的,而秸秆覆盖处理的地下生物量低于CK的;与CK相比,地膜覆盖处理春小麦的籽粒产量增加了2.2%~10.9%,石子覆盖处理增加了0.86%~3.50%,秸秆覆盖处理增加了-6.9%^-9.4%;在各覆盖处理间春小麦的千粒重、穗数和每穗小穗个数均无显著性差异。因此,地膜覆盖处理最有利于提高春小麦的籽粒产量。
The effect of spring wheat growth and yield were studied by the different mulching treatments at field trails. The results were as follows： the plant height,leaf area index and the aboveground biomass of mulching treatments were larger than the un-mulching treatments. But the underground biomass of mulching treatments was smaller than the un-mulching treatments. Compared with the CK treatment,the grain yield of plastic film mulching treatment was increased by 2. 2% ~ 10. 9%. And the grain yield of stone mulching treatment was increased by 0.86% ~ 0.35%. The grain yield of straw mulching treatment was increased by- 6.9% ^- 9.4%. There were no significant differences of 1000- seed weight,the number of spikes and the number of spikelets per spike among the mulching treatments. Plastic film mulching treatment compared with other treatments was better to improve crop yields,which was the best planting method in the oasis area.
