| 摘 要： | 针对辽西风沙半干旱区降水少、干旱频发、土壤瘠薄,玉米秸秆资源丰富的现状,重点研究了秸秆与氮肥配施对玉米生长发育及水分利用效率的影响.试验设4个秸秆还田量水平,2个施氮量水平.结果表明,秸秆还田配施氮肥对玉米生长前期和中后期的影响差别较大,对玉米早期生长有一定的负面作用,中后期秸秆还田正效应逐渐得到体现,玉米生长及水分利...

| Abstract: | In view of the current situation of rainless,poor soil and a large amount of maize straw in semi-arid area of western Liaoning Province,4 levels of straw application rate plus 2 levels of nitrogen fertilizer were designed to study the effect of straw and nitrogen fertilizer on the growth,development and water use efficiency of maize.The results showed that the effect differenceof corn straw plus nitrogen fertilizer on the growth of maize between early stage and middle-and-late stages were great.At the early... |
