| 摘 要： | 在旱作条件下,对免耕与耕作麦地土壤含水量变化的研究,在小麦整个生育期降雨量为128.17mm的情况下,只要在冬小麦关键的需水高峰期,有相应的有效降水,使土壤不出现干层,土壤含水量能够满足小麦生长的需要,是能够取得7000kg/hm2以上产量的.0-20cm的土壤含水量耕作的比免耕的低0.62%-0.87%,20-40cm、40-60cm、60-80cm的含水量耕作的比免耕的都高,并随着深度的增加而提高,分别高0.06%-0.92%、0.13%-0.96%、0.28%-1.05%.但差异不显著,小麦生物产量、经济产量耕作的比免耕的都高,但差异也不显著.因此,在旱作条件下,管理措施得当,免耕仍能取得与耕作相同的效果. |
| 关 键 词： | 旱作 免耕 耕作 土壤含水量 小麦产量 |

| Abstract: | In dry conditions,no-tillage cultivation of wheat on changes of soil water content in was studied under condition of 128.17cm annal rainfall throughout the growing period The result showed that if there are effeetive precipation in the high water period The soil water contents could meet the demend for growht and reached up 7000kg/hm2 yields soil water content in 0-20cm of tillage soil than the no-tillage farming vlowover,the soil water contents in 20-40 cm,40-60 cm 60-80 cm of tillaged,0.06%-0.92%-0.96% 0.... |
