Studies on yield and nutrition value of mixed pasture with cocksfoot and companion species under different mixture sowing ratios
Used cooksfoot,brome,white clover and alfalfa as experimental forages,we designed 4 monocul-ture treatment [1.cocksfoot;2.Brome (Bromus inermis );3.white clover (Trifolium repens );4.alfalfa (Medi-cago sativa )],15 combinations of cocksfoot mixed with brome,white clover and alfalfa under 5 mixtures ratios and the pasture without sown forage.The yield and nutrition value of all treatments were measured.The results indicated that (1)the yield of the mixture of cocksfoot and alfalfa was the highest ,which reached from 7 503 to 14 676 kg/hm2 .The yield of weeds was the lowest,which was 26~94 kg/hm2 ;(2)the dry matter of the treat-ment 30%CF+70%L was the highest,which was 14 676 kg/hm2 ;(3)Compared with the monoculture treat-ment,the mixture could increase the content of crude protein and fiber of cooksfoot,the crude protein content of cooksffot was the highest (1 9.44%)in the treatment 90%+10%L.The crude protein of brome and alfalfa were higher than that of on monoculture treatment;(4)the crude ash of cooksfoot was decreased in the mixture treat-ments,In contrast,the crude ash of cooksfoot in the monoculture treatment was higher,which reached 1 6.05%.
