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 experiments showed that compared with the open-field sowing method, double-ridged sowing with full film could increase yield of dry-land millet by 52.7%, net income by 2 392 yuan / hm 2 and water production efficiency by 40.4% Can increase the yield of dry farmland millet by 16.7%, net income by 178 yuan / hm ~ 2 and water production efficiency by 25.5%. The double-ridge furrow sowing of the whole film occurred due to rain after the sowing and the compaction could not be easily broken, which seriously affected the emergence and population density Lower, resulting in 5.6% to 8.3% reduction. It is suggested that poplar and double-ridge side-sowing cultivation modes should be promoted in the dry farming area of southern Ningxia. When the land is flat and the conditions of water and fertilizer are good, the whole-shroud soil-seeded planting and training mode should be promoted.
