【摘要】 3年研究资料表明，小麦地膜覆盖，发挥了以节水效应为主导的增温效应、光能效应和促根效应，因而植株表现为生理功能增强，生育进程加快，灌浆速度提高，粒重增加，穗粒数增多，根系扩大，根际土壤微生物增多。采用覆膜穴播的方式，在旱地，较对照增产小麦856．5kg／hm2，增产率为21．1％，小麦耗水量0．926mm／kg，较对照减少16．7％；在水地，较传统对照增产小麦342－417kg／hm2，增产率为7．7％－11．1％。更多还原

【Abstract】 In this paper,we studied film mulch technique of winter wheat in Yuncheng regions. 3 years -data indicated that film-mulching wheat could play the role of its saving water effect, temperature increasing effect, light and energy effect and root growth enhancing effect. Therefore, the plant showed its physiological function enhancing, growth process quickening, the speed of filling raising, grain weight and grains/ear increasing. The roots were extended, microorganisms around the roots were increased. Compared with the control, for film-mulching hilldrop in dryland, the yield of wheat grain was increased by 856. 5 kg/ha and the increasing rate was 21.1%; wheat grains per kilogram consumped water 0.926mm and compared with the control, water consumption was decreased by16.7%. In irrgated fields, compared with the traditional control, grain yield was increased by 342~417kg/ha and the increasing rate was 7. 7%~11.1%.更多还原
