谷子不同覆膜栽培方式效益对比

Comparative Study on Millet Output under Different Films

田间试验结果表明,相对于露地条播种植方式,全膜双垄侧播栽培可使旱地谷子增产52.7%,纯收入增加2 392元/hm^2,水分生产效率提高40.4%;全膜覆土穴播栽培可使旱地谷子增产16.7%,纯收入增加178元/hm^2,水分生产效率提高25.5%;全膜双垄沟播栽培因播后遇雨发生板结,且板结不易破除,严重影响出苗,群体密度较低,导致减产5.6%~8.3%。建议在宁夏南部旱作农业区谷子生产上应加快推广全膜双垄侧播栽培模式,在土地平坦、水肥条件较好的情况下则应重点推广全膜覆土穴播栽培模式。

Field test results show that compared to the outdoor seeding, full film double ridge sowing can make dryland millet production increase 52.7%, increase the net income of 2 392 yuan/hm^2, enhance water production efficiency 40.4%; Membrane covering all dibbling can make dryland millet production increase 16.7%, increase the net income of 178 yuan/hm^2,enhance the production efficiency of water 25.5%; It was suggested in this paper that the rainfed agricultural area in southern Ningxia millet production mainly should speed up the promotion of whole side double ridge cultivation mode, in the case of flat land, the effects good should focus on promoting the whole film dibbling turns the soil cultivation mode.
