| 摘 要： | 旱地冬小麦渗水地膜全覆盖穴播试验表明，渗水地膜覆盖的土壤含水量明显高于常规地膜覆盖的含水量；渗水地膜在显著提高地温的同时可以降低午时的极端高温；渗水地膜覆盖的冬小麦比常规地膜覆盖的冬小麦平均增产15．7％，比不覆盖小麦增产102．2％。

A Test of the Winter Wheat Bunch Sowing with Water-osmosis Plastic Membrane Covering in Semi-arid Land |
| |
| Abstract: | Water-osmosis plastic membrane is a kind of new explioted product based on validating small raiofall(≤10mm). The test of the winter wheat covered with water-osmosis plastic membrane showed that it had 15.7% increase in yield compared to conventional membrane and 102.2% increase compared to no-cover. It can improve rainfall penetration into soil vertically, modify maximum soil temperature, and ventilate soil, while it also can increase soil temperature and block evaporation as the conventional membrane does. |
