1.一年生的牧草禾本科。冬牧-70黑麦、八倍体小黑麦、高抗寒的意大利黑麦草、十字花科的牛皮菜等。这些牧草生长的时间自秋季的9-10月份到来年的5月底、6月初刈割利用完毕。在这期间虽然因品种不同可刈割的次数和收获的草的产量会有差异,但总体上看,可有效地解决冬春两季畜禽缺青、青饲料供给不足的问题。 1. annual grasses. Winter animal husbandry -70 rye, octagonal triturates, high cold Italian ryegrass, cruciferous cabbage and other vegetables. The growth of these grasses has been completed since September and October in the fall and the end of May and the beginning of June in the coming year. Although there may be differences in the number of crops that can be cut due to different varieties and the yield of grass harvested during this period, on the whole, the problem of shortage of green fodder and insufficient supply of green fodder can be effectively solved in winter and spring.
