为解决本市奶牛青饲料紧缺和鱼塘青饵料不足,亟需研究提出若干套全年亩产鲜草不低于100公担,具有一定经济效益的周年供青高产栽培方案。为验证以禾本科高产饲料黑麦草、杂交狼尾草为主,适当搭配豆科饲料,使其复合群体充分利用光能与地力,实现青饲高产、周年供青的可行性。于1986年秋至1988年秋,在上海农学院实验农场开展了二年试验研究,同时第二年度还在芦潮港农场进行了生产示范。现将研究结果报告如下: 一、研究经过概况试验安排在本院实验农场,面积1亩以上。畦
In order to solve the shortage of green feed for dairy cows in the city and the shortage of feed for fish ponds, it is urgently necessary to study and propose several sets of anniversary annual high yielding cultivation programs with no less than 100 kgs of fresh grass per mu per year and with certain economic benefits. In order to verify the high-yielding grass ryegrass, hybrid Pennisetum, with the appropriate legume feed, make its compound population make full use of light and ground force to achieve the high yield of green feed, the annual availability of green. From autumn 1986 to autumn 1988, a two-year experimental study was carried out at Shanghai Agricultural College Experimental Farm, and the second year, a production demonstration was carried out at Luchaogang Farm. Now the research results are reported as follows: First, the study was arranged in an experimental farm in our hospital with an area of more than 1 mu. plot
