种草养畜事业的发展,优良品种起着重要作用。我们经过多年的研究努力,在饲草方面培育出了“重庆高”和“广益”牛鞭草新品种,现简介于后:一、重庆高牛鞭草1、品种来源,原种匍匐野生,1974年杜逸在重庆市郊采回种苗,按优质高产直立为目标,进行了株行圃无性系选育。经生长、发育、繁殖、农艺性状和12个地方野生种的比较试验,获得了株高直立,易于割草的品系。1979年后,在15个点的栽培和饲用评价,最高年产量,每公顷鲜草达183.7吨(干物质25.6吨)可割5—6次,草质好,不易老化,适口性佳,故命名为“重庆高”牛鞭草(Hemarthria altissima cvchonging Alta),简称“重高”。
Growing grass livestock business, good varieties play an important role. After years of research efforts, we have fostered a new breed of “Chongqing High” and “Guangyi” Verbena in forage grass. Now we are briefing on the following: First, the high verbena 1 in Chongqing, source of species, creeping wild In 1974 Du Yat seedlings back in the suburbs of Chongqing, according to the goal of high yield and quality upright, conducted a nursery line nursery breeding. By the growth, development, reproduction, agronomic traits and comparative experiments of 12 wild species, the plant height of the erect, easy to mow the line. After 1979, at the 15-point cultivation and feed evaluation, the maximum annual yield of fresh grass per hectare reached 183.7 tons (25.6 tons of dry matter) can be cut 5-6 times, good grass quality, not aging, good palatability, It is named “Chongqing high” Hemarthria altissima cvchonging Alta, referred to as “heavy.”
