临夏川塬灌区饲用玉米引种试验研究

Studies on Introduction Experiment of Silage Maize in Linxia Plain-Highland Irrigation Area

本文主要引进饲用玉米鲁单9066、金凯3号、先玉335、文玉3号、丰贮1号5个玉米品种在临夏川塬灌区试验种植,结果表明5个饲用玉米品种均适合临夏川塬灌区种植,其中丰贮1号在产草性状上均优于其他4个饲用玉米品种,其生育期为159d,株高达到312.12cm,叶片数达到14.53个,鲜草产量达到8 545.23kg/667.7m2,达到了显著差异(p<0.05)。

In this paper, five maize varieties were cultivated including Ludan 9066, Jinkai 3, Xianyu 335, Wenyu 3 and Fengzhu 1 in Linxia plain-highland irrigation area. The results showed that five maize varieties are suitable for planting in Linxia plain-highland irrigation area. In the herbage traits, Fengzhu 1 was significantly superior to that of the four silage maize varieties（P〈0.05）, and its growth period was 159 d, plant height reached to 312. 12 cm, and the number of leaves reached to 14.53,and the yield of fresh grass reached to 8 545.23 kg/667.7m2.
