盘固草(A24及A254)主要于3—10月份生长是多年生的夏季牧草。克育草较适于低温环境,10～4月份草量占全年的78.4％,其中以3、4月份时生长最佳、年产草量为每公顷80吨是多年生的冬季牧草。两草混植后、由于克育草的旺盛生长,抑制了盘固草生长、使得盘固草产量有所下降。混植区全年产草量 Paniculata (A24 and A254) is a perennial summer foraminifera mainly grown from March to October. K grass is more suitable for low temperature environment grass, 10 to April accounted for 78.4% of the annual amount of grass, of which the best growth in March and April, the annual output of 80 tons per hectare is perennial winter pasture. After the two grasses were planted, due to the vigorous growth of the grass, the growth of the reed grass was inhibited and the yield of the reed grass decreased. The planting area produces grass all year round
