在宁南旱作农业区用豌豆进行的田间试验表明 :采用微集水种植方式 ,豌豆耗水量增加 96.5%～1 1 4.9%,产量提高 4 8.4 %～ 90 .2 %,水分利用效率达 4 .55～ 8.63 kg/mm· hm2 ;处理中窄垄型增产效果优于宽垄型。集水种植技术是提高半干旱地区降水利用率的有效种植方式 Field experiments with peas in dry farming areas in southern Ningxia showed that the water consumption of pea increased by 96.5% -1 11.9%, the yield by 8.42% -90.2% and the water use efficiency by 4 .55 ~ 8.63 kg / mm · hm2. The treatment effect of narrow ridge type was better than wide ridge type. Catchment cultivation technology is an effective planting method to improve precipitation utilization in semi-arid areas
