评价了十个种类牧草和一组混播牧草在三个不同生长期的产量及适口性。俄罗斯野麦草的适口性最好,但产量最低;中间冰草产量最高,但适口性差;雀麦是产量高适口性也好的品种。豆科植物中,鸟足三叶草的适口性最好,产量也相当高;苜蓿产量高,适口性也好。试验证明,从牧草产量和适口性两方面来看,混播牧草都优于单一草种的草场。在牧草生长的一定时期中,其含水量、粗蛋白质、消化半和粗纤维均对适口性有影响。
The yield and palatability of ten species of pasture and a group of mixed-forage grasses in three different growing stages were evaluated. Russian wheat straw palatability best, but the lowest yield; middle ice grass production highest, but palatability is poor; broccoli is yield high palatability Ye Hao varieties. Leguminous plants, bird foot clover palatability best, the yield is quite high; alfalfa yield, palatability is good. Experiments show that, from the forage yield and palatability of two aspects, mixed-flowering grass is better than single grassland pasture. In a certain period of pasture growth, the water content, crude protein, digestion half and crude fiber all have an impact on palatability.
