1985年由新西兰引种的优良禾本科收草—黑麦草首次吞新疆博乐地区试种成功,5月1日播种,5月5日出苗,当年可收获3~5次,每茬生长高度平均50厘米,最高达70厘米,在试验地可亩产鲜草4000~5000公斤。这种牧草品种具有分蘖
The 1985 introduction of good grasses introduced by New Zealand grass - rye grass for the first time swallowing Xinjiang Bole region successful trial, May 1 sowing, May 5 emergence, the year can be harvested 3 to 5 times, the average growth height per crop 50 Cm, up to 70 cm, in the test can yield 4000 to 5000 kg of fresh grass. This forage species has tillers
