| A trial of mulching with different materials for drought resistance in summer-sowed corn cultivation was carried out in Yanting County,a drought area of Mianyang,Sichuan.The result showed that mulching with plastic film could increase soil temperature and water content,while mulching with crop straws and shells could decrease soil temperature and increase water content,and the effects of mulching materials on raising corn yields were plastic film>wheat straw>rice straw>corn straw>wheat shell>rapeseed shell.If economic and ecological benefits are considered,wheat straw is the best mulching material for drought resistance in corn cultivation. |
