摘要
试验为解决优质饲草品种匮乏的问题,对采集的野生秣食豆种质资源进行单株混合选育和株系混合选育,择优去劣选育出产量高、耐盐碱的‘龙牧茶’秣食豆新品种。结果显示,‘龙牧茶’秣食豆多年多点的平均干草产量高达14201.46 kg/hm^(2),与对照(松嫩)相比,4个不同试验点的干草产量分别提高了17.06%、15.16%、16.12%和16.45%;在pH值8.2的盐碱地生长良好。研究表明,‘龙牧茶’秣食豆粗蛋白含量高、适口性好、消化率高、耐盐碱,适宜在黑龙江省推广种植。
The experiment is to solve the problem of shortage of high quality forage varieties and to cultivate new forage varieties with high yield and salt tolerance,the single plant mixed breeding and line mixed breeding of wild forage legumes resources were carried out,a new variety'Longmucha'forage soybean with high yield and salt tolerance was selected.The results of the production test showed that the average hay yield of'Longmucha'on multiple years was 14201.46 kg/hm^(2),compared with the control(Songnen),the hay yield of four experimental sites increased by 17.06%,15.16%,16.12%,and 16.45%.It grew well in saline soil with a pH value of 8.2.The research shows that'Longmucha'forage soybean has high protein content,good palatability,high digestibility and salt-alkali resistance,it is suitable to be planted in Heilongjiang Province.
