摘要
为了缓解干旱,减少环境污染,增加农民收入,2010—2011年在宁夏西吉县开展了旱地马铃薯全膜双垄覆盖"一膜两季"免耕栽培模式研究。结果表明":一膜两季"免耕栽培模式较露地栽培土壤含水量提高20.04%,马铃薯产量和商品薯分别提高11.0%和14.8%,经济效益增加27.6%;较其他栽培模式土壤水分含量、经济收入显著增加;节本增效作用较为明显,在推广应用中应根据实际情况给予重点考虑。
In order to alleviate the drought, reduce environmental pollution, increase farmer income, a study of no-tillage cultivation of "one film used for two seasons" of potato in Xiji county of Ningxia was carried out from year 2010 - 2011. The results showed that: soil moisture content of no-tillage cultivation has been increased by 20.04% than that of open field cultivation, the potato yield and commodity potato were increased by 11% and 14.8% respectively, the economic efficiency increased by 27.6%. Compared with other cultivation mode, the no-tillage cultivation of "one film used for two seasons" had increased soil moisture and economic benefit.
