摘要:
通过品种筛选和覆膜方式试验，认为地膜双垄沟和宽膜覆盖种植是黄土高原旱地玉米抗逆减灾的新技术，与之配套的高产品种为豫玉22和金穗2001.以金穗2001为参试品种，地膜双垄沟种植和140cm宽膜种植产量最高，分别比普通地膜玉米增产1271.4kg/hm2和971.4kg/hm2，水分生产率达26.9kg/mm和25.2kg/mm，并且有效增加了穗粗、穗粒数、百粒重、穗粒重等经济性状，值得推广。
Abstract:
Through selecting varieties and mulching forms test, it is found that double mulch ridge and wide film mulching cultivation is a new technique to stress tolerance and reducing disasters in dryland on Loess Plateau.Matching with this new technology, Yuyu 22 and Jinsui 2001 were higher yield varieties.The yield of Jinsui 2001 in the double mulch ridge and in the 140 cm wide film mulching treatments were the highest, they were increased 1 271.4 kg/hm2 and 971.4 kg/hm2 more than normal film mulching.Soil moisture producing rate were 1.79 kg/mm and 1.68 kg/mm respectively, and the economic indexes of corn increased notably.Hence these mulching forms be recommended.
