地膜覆盖穴播栽培技术是旱地小麦实现优质、高产稳产的有效途径。研究结果表明,地膜覆盖穴播小麦产量高低与土壤底墒关系密切。在旱地应用该技术时要因夏闲期降水多少和底墒状况而定。夏闲期降水多、底墒好的年份可采用该技术;夏闲期降水少、底墒差的年份会出现增产不增收的结果。

The technology of film-mulched and bunch-seeding cultivation is an effective way to accomplish top quality,high and stable yield of dryland wheat.The experiment results indicate that yield of film-mulched and bunc-seeding wheat is colsely related with soil moisture before sowing.Therefore,the application of this technology should be adjusted according to rainfall during summer fallow and soil moisture before sowing.It may be used in the years with rich rainfall during summer fallow and with good soil moisture condition,yet in the years with inadequte rainfall and poor moisture condition,it may cause increase in production but decrease in income.
