冬牧-70黑麦(Secale carele L.wintegr-azer-70)是美国Pennigten种子公司于60年代在“1030黑麦”品种中选育出的优良禾本科牧草,并在亚拉巴马州、乔治亚州等地与14个黑麦品种进行比较试验,每公顷干物质产量比其它品种高17～21％,居第一位。 冬牧-70在美国东南部的几个州都有种植,是美国目前生产性能最好的冬季牧草之一,并认为是保证牛群有绿色冬牧场的最好饲草。该草于1979年由美国引入我国,几年来在北方、江浙和西南地区进行试验,表现较好。特别在南方可作为冬春青绿饲草栽培。 一、植物学特征与生物学特性 冬牧-70黑麦是禾本科黑麦属越年生草木植物,须根发达主要分布于15～20公分土层。分蘖20个左
Secale carele-70 rye (Secale carele L.wintegr-azer-70) is a Pennigten seed company in the United States in the 60’s in the “1030 rye” breed elite grasses, and in Alabama, Georgia State and other places with 14 rye varieties for comparative experiments, dry matter yield per hectare than other varieties 17 to 21%, ranking first. Wintergrass-70 is planted in several states in the southeastern United States and is one of the best-performing winter grasses in the United States and is considered to be the best fodder to ensure herds have green winter pastures. The grass was introduced into our country by the United States in 1979 and has performed well in recent years in northern China, Jiangsu, Zhejiang and southwestern China. Especially in the south can be used as winter green forage cultivation. First, the botanical characteristics and biological characteristics of winter grazing -70 rye is a perennial grassy rye plant grass, fibrous roots developed mainly distributed in 15 to 20 cm soil layer.
