秸秆还田后接种蚯蚓对夏玉米主要农艺性状及产量的影响
Effect of Inoculating Earthworm after Straw Returning to Field on Main Agronomic Characteristics and Yield of Summer Maize
摘要
Abstract
A field experiment was conducted in this research to study the effect of inoculating earthworm after wheat straw returning to field on agronomic characteristics and yield of summer maize on dryland of Northwest China. The results showed that inoculating earthworm after wheat straw returning to field accelerated the decay rate of wheat residue, and improved soil fertility. Significant increases in the plant height,the first and second base internode diameters,leaf area index and leaf area of three ear-leaves were observed, compared with the control and wheat straw returning. Grain numbers per ear and one hundred grain weight in the treatment of inoculating earthworm increased by 6. 1% and 7. 8% respectively, compared with the control,and the yield in the treatment of inoculating earthworm was 14. 5% and 5. 2% higher than the control and wheat straw returning, respectively. These results indicated that inoculating earthworm after wheat straw returning to field was an effective method to increase summer maize yield.关键词
