岗岭地牧草栽培与利用

为探讨开发利用岗岭低产土地资源的有效途径,从1984—1989年在踢球山种畜场进行牧草栽培,一年生草地每公顷产鲜草平均85815公斤,多年生草地平均每公顷产鲜草49275公斤。每天每头奶牛饲喂15公斤鲜草以代替部分干草,每月比精料加粗料常规饲喂方法增奶量为34.6%,每公顷鲜草饲喂增值效益达6000元以上。

THE CULTIVATION AND COMPREHENSIVE UTILIZATION OF FODDER GRASS IN MOUNTAIN RIDGE AREAS

In order to explore the possibility of cultivating mountain ridge areas for fodder grass growth,fodder grass was discriminated in Tiqiu Mountain Farm during the years from 1984 to 1989.The outcomes are, the average yield on annually cultivated grassland is 85815kg of pasturage per hectare;the average output on the perennially cultivated grassland 49275kg.One milking cow can have an increase of 34.6% of its milk monthly when fed on 15kg fresh grass every day instead of part of dry fodder.Then,it is estimated that through growing fodder grass,one hectare of mountain ridge land can produce a value of more than 6000yuan RMB annually.This shows that cultivating ridge areas in this way is economic and applicable.
