| 摘 要： | 针对宁南山区主要作物马铃薯、地膜玉米在播种季节相对干旱的现实问题,开展不同土壤含水率出苗试验,探索适宜播种的土壤含水率。地膜玉米播种时适宜的土壤含水率在15%,马铃薯播种时适宜的土壤含水率在11%～12%,低于此标准时,需进行补灌种植,灌溉水量一般为0.5kg/穴,出苗率可达到75%～90%。 |

| Abstract: | The emergence tests of different soil moisture was carried out,and the suitable soil moisture of sowing was studied as to the practical problem of relatively arid for main crops such as potatoes and mulched maizes when sowing in mountain area of Southern Ningxia.The results showed that the suitable soil moisture for the mulched maizes when sowing was at 15%,and the potatoes was at 11%~12%.While it was lower than this standard,supplementary irrigation was required.When irrigation quantity was generally 0.15k... |
