旱地冬小麦覆盖黑色液膜生态效应研究

Ecological effects of black fluid-film mulched over in dry land winter wheat

摘要: 对旱地冬小麦覆盖黑色液膜的增产效应研究结果表明，枯水年型旱地冬小麦覆盖黑色液膜具有较好的生态效应，冬小麦产量达2188.5kg/hm²，较对照增产17.95%；水分利用效率达0.78kg/m³，较对照提高22.26%。

Abstract: The results from field experiment show that the application of black fluid-film has a good ecological effect in dry years, and the yield reaches 2188.5kg／hm², 17.95% increased compare with the control. The water use efficiency is 0.78kg／m³, 22.26% higher than that of the control.
