旱地不同施肥对冬油菜产量及土壤水分状况的影响OACSCDCSTPCD
Effects of different fertilization on winter rapeseed yield and soil water in dry land
研究了不同施肥处理下黄绵土区冬油菜产量、土壤水分状况及其水分利用效率的变化.结果表明:有机肥与化肥配施明显提高了冬油菜籽粒产量和水分利用效率,较不施有机肥平均提高了12.95％和10.74％;冬油菜产量以有机肥配施氮磷钾处理最高,为l 180.05 kg· hm-2,较对照(不施肥料)提高了369.32％,耗水量和水分利用效率也最高,分别为489.73 mm和2.41 kg·hm-2·mm-1,较对照分别提高了6.40％和338.18％;冬油菜收…查看全部>>
A study on the effects of different fertilization conditions on the yield of winter rapeseed,soil water and water use efficiency was carried out in dry land of Loess Plateau.The results showed that the yield of winter rapeseed and water use efficiency were extremely increased in manure combined with chemical fertilizer,it was increased by 12.95％ and 10.74％ respectively compared to that without manure.The highest yield and soil water consumption and water use…查看全部>>
