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
Film-mulched-hole sowing cultivation technology is an effective way for dryland wheat to achieve high quality, high and stable yield. The results showed that the yield of mulching wheat under plastic film mulching was closely related to soil moisture. When applying this technique in drylands, it depends on the amount of rainfall and the amount of soil moisture during summer. Precipitation more in summer and summer, good soil moisture at the end of the year can be used in this technology; less summer rainfall, the end of the poor yield increase will yield results
