摘要
在旱作农业生产中,施用土壤保水剂,作物产量可比对照平均提高13.2％～31.3％,每亩可增产粮食24.5～66.2kg。其中蚕豆、春小麦每亩沟施500g,马铃薯每亩沟施1500g的处理最为显著,对应的增产率分别是29％,34.4％,30.9％。此项技术措施是旱作栽培中“高效栽培”的新途径。
In dryland farming production, applying soil moisture maintainer(mois-ture-preserving agent) increased crop yields by 13.2%～31.3% in comparison with thecontrol on an average, and crop yield per mu rose up by 24.5～66.2kg. Of which broadbeans and spring wheat treated with 500g per mu and potatoes with 1500g per mu byditch application had a remarkable yield increase in correspondance with the increasingpercentage of 29%, 34.4% and 30.9% respectively. This technical measure is a newway of highly effective cultivation in dryland farming cultivation.
