摘要
集旱作农业耕作栽培技术的优良传统,通过建造丰产沟,配方施肥,地膜覆盖等,进一步提高耕地的蓄水保墒能力,提高地温,改良土壤,可取得显著的减灾增产效果。每毫米降水平均产粮1.114～1.767kg。试验比对照田亩增产粮食402.4kg。
The fine tradition of cultivation technique of intensive dryland farmingcan further improve the ability of farmland to store and conserve moisture,raise farmland temperature and improve soil fertility by constructing bumperharvest gullies,formula fertilizer application and plastic sheet multching incultivation whereby to reduce disasters and obtain yield increase.Rainfall waterper mm can produce 1.114-1.767 kg of grain on an average.The yield in-crease in the trial field per mu is 402.4 kg higher than that in the control.
