秸秆与氮肥配施对小麦产量及氮素吸收利用的影响
Effect of Combined Use of Straw and Nitrogen Fertilizer on Wheat Yield and Nitrogen Utilization
摘要
Abstract
The effect of combined use of straw and nitrogen fertilizer on wheat yield , thousand-kernel weight, nitrogen use rate and nitrogen benefit were studied by field experiments .The results indicated that the thousand-kernel weight was the highest as 39 .4 g when treated with nitrogen at the ratio of basal to dressing as 6∶4.The yield was the highest when treated by nitrogen at the ratio of basal to dressing as 7∶3, and then the one at the ratio of 6∶4 , but there were no significant differences between them .The nitrogen use rate and nitrogen benefit were the highest when treated by nitrogen at the ratio of basal to dressing as 6∶4 .So under the test conditions , the best treatment was nitrogen at the ratio of basal to dressing as 6∶4 combined with full corn straw returning , followed by the treatment with nitrogen at the ratio of 7∶3 .Under the condition of straw retur-ning, optimally increasing nitrogen amount at earlier stage could promote wheat growth and improve nitrogen u -tilization.关键词
