Abstract: In order to explore the optimal water and fertilizer application rate for Echinochloa frumentacea ‘Haizi No.1’ in the semi-arid area of Ningxia， a split-plot experiment was carried out with three irrigation amounts and three fertilizer application rates， and a total of nine treatments were set， including W1F1 （irrigation amount 900 m3·hm-2， fertilizer amount 300 kg·hm-2）， W2F1（irrigation amount 1350 m3·hm-2， fertilizer amount 300 kg·hm-2）， W3F1（irrigation amount 1800 m3·hm-2， fertilizer amount 300 kg·hm-2）， W1F2（irrigation amount 900 m3·hm-2， fertilizer amount 600 kg·hm-2）， W2F2（irrigation amount 1350 m3·hm-2， fertilizer amount 600 kg·hm-2）， W3F2（irrigation amount 1800 m3·hm-2， fertilizer amount 600 kg·hm-2）， W1F3（irrigation amount 900 m3·hm-2， fertilizer amount 900 kg·hm-2）， W2F3（irrigation amount 1350 m3·hm-2， fertilizer amount 900 kg·hm-2）， and W3F3（irrigation amount 1800 m3·hm-2， fertilizer amount 900 kg·hm-2）. The results showed that the effects of different water and fertilizer treatments on plant height of Echinochloa frumentacea were significant （P<0.05）. The plant height increased with the growth periods， and reached the maximum at the dough stage， and the maximum plant height was 1.93 m under W2F1 treatment. Fresh weight and dry weight were significantly affected by water and fertilizer （P<0.05）， fresh weight increased first and then decreased， and dry weight continually increased. Under W3F2 treatment， the fresh weight reached the maximum at the heading stage， 93 385 of kg·hm-2， and the dry weight reached the maximum，24 500 kg·hm-2， at the dough stage. W1F3 at the jointing stage， W3F1 at the heading stage and W3F2 at the dough stage， the crude protein and relative feeding value reached a higher level， and the forage quality was better. The results of this study could be used as a reference for water and fertilizer application for Echinochloa frumentacea in Ningxia region.

摘要： 为探寻宁夏半干旱区湖南稷子（Echinochloa frumentacea）‘海子一号’的最佳水肥配施量，本研究采用裂区试验，设置3个灌水量和3个施肥量，共九个处理：W1F1（灌溉量900 m3·hm-2，施肥量300 kg·hm-2），W2F1（灌溉量1350 m3·hm-2，施肥量300 kg·hm-2），W3F1（灌溉量1800 m3·hm-2，施肥量300 kg·hm-2），W1F2（灌溉量900 m3·hm-2，施肥量600 kg·hm-2），W2F2（灌溉量1350 m3·hm-2，施肥量600 kg·hm-2），W3F2（灌溉量1800 m3·hm-2，施肥量600 kg·hm-2），W1F3（灌溉量900 m3·hm-2，施肥量900 kg·hm-2），W2F3（灌溉量1350 m3·hm-2，施肥量900 kg·hm-2），W3F3（灌溉量1800 m3·hm-2，施肥量900 kg·hm-2）。结果显示，不同水肥处理对湖南稷子株高影响显著（P<0.05），株高随生育期升高，蜡熟期达到最大，W2F1处理下最大株高可达1.93 m。鲜、干重受水肥影响显著（P<0.05），鲜重呈先升高后降低趋势，干重持续升高。W3F2处理下鲜重于抽穗期达到最大值93 385 kg·hm-2，干重于蜡熟期达到最大值24 500 kg·hm-2。在拔节期 W1F3、抽穗期 W3F1、蜡熟期 W3F2 处理下，粗蛋白和相对饲喂价值均达到较高水平，饲草质量较好，该研究结果可作宁夏地区湖南稷子水肥配施参考依据。
