威宁县紫花苜蓿品种筛选试验报告

在威宁县选择土壤肥力中等以上,pH6.2,平整,不积水,长度与宽度达到试验要求的地块进行8个紫花苜蓿品种3次重复的比较试验,通过对物候期、生物产量、分枝数和植株高度进行对比分析,结果表明:WL525HQ、迪特两个品种分枝数较多,植株较高,生物产量较高,可以在该县范围内大力推广。

The plots with medium soil fertility,pH6.2,flat and no stagnant water,and the length and width of 8 alfalfa varieties were compared for 3 times in Weining County.Through the comparative analysis of phenological phase,biological yield,branch number and plant height,the results showed that WL525HQ and Ditte had more branches,higher plant and higher biological yield,so they could be popularized in the county.
