生产紫花苜蓿叶粉适宜刈割期为现蕾至10%开花。
The distribution of flowering phase of plant in grassland community was studied by localized observation on phenological phase of species.通过草地群落物种物候期定位观测,研究了植物种的花期分布规律。
Their correlation coefficients with the days from picking off leaves to full flowering phase were-(0.62) and(-0.45), respectively(P<0.05).它们与摘叶期至盛花期天数的相关系数分别为-0.62和-0.45,经检验,差异达到显著水平。
