摘要: 为探究深松耕作下内蒙古西部平原的灌水制度,设置了深松条件下的4个灌水次数处理,分别为灌水1次、灌水2次、灌水3次和灌水4次。结果表明:深松耕作下,灌水有促进耕层土壤容重降低的作用,并显著降低25~40 cm土层土壤的紧实度;灌水次数越多,土壤含水量、水分利用效率及叶片水分利用效率越高,随着灌水次数的增加,春玉米的千粒质量显著增加并增产。

Abstract: To explore the irrigation system under subsoiling tillage for western plains of Inner Mongolia,four irrigation times treatments were set under subsoiling which were 1 time,2 times,3 times and 4 times irrigation. The results showed that:irrigation had the effect of promoting the reducing of soil bulk density of plough layer under subsoiling and subsoiling can significantly reduce soil compaction in the range of 25 ~40 cm. The more irrigation times were, the higher soil moisture,water use efficiency and leaf water use efficiency were.With the increase of irrigation times, spring maize grain weight was increased significantly and then the yield was increased.
