摘要
介绍了新品种饲料桑的生物、生态学特性,研究了在不同栽培密度条件下一年生饲料桑的产量变化规律,发现一年生饲料桑主枝地径、主枝条长呈现缓慢生长、快速生长、停止生长的规律,一年生饲料桑主枝条的长度的地径和叶数都比次枝条的生长速度快;2年生饲料桑不同刈割时期的产量及其枝叶营养成分变化的规律,饲料桑不同月份营养成分不同,饲料桑叶粗蛋白含量最高,枝含量次之。研究发现新品种饲料桑产量高,营养丰富,饲用价值大,是极具开发潜力的功能性饲料资源。同时对饲料桑的收获、加工利用方法技术也作了简要阐述。
Forage mulberry is a new cuhivar of forage with the characters of high yields, rich nutrition and great potential development. Its biological and ecological characters are introduced in this paper. Basing on different cultivated densities of forage mulberry, the law of yield variation in forage mulberry was studied. The growing law of base diameter, length and the number of leaves in main branches for one year forage mulberry were the process of slowly,rapidly and inactively,and they grew faster than those in secondary branches. Yield changing of branches and leaves for the two-year forage mulberry and their nutrition components in different mowing dates were concluded. As a result,nutrient components of forage mulberry were not the same in different months. Leaves of forage mulberry contain the most content of crude protein and branches afterwards. Meanwhile, techniques for harvesting, processing and utilization of forage mulberry are also expounded briefly in this paper.
