青贮玉米是发展奶牛业的当家饲料。目前,上海郊区麦/青贮玉米——稻粮饲结合种植制的面积已达数万亩之多,但对其中的青贮玉米栽培措施研究甚少,因而产量不高不稳。近年来,笔者在青贮玉米的高产栽培配套技术方面进行了试验研究,本文着重对品种试验评价作一初步探讨。一、材料和方法(一) 供试品种以金皇后作对照种与上海市农科院的沪单5号,江苏农学院的 M_5P,南京的土种疵粒深,辽宁农科院的辽原1号,广西玉米所的墨白1号进行对比试验。
Silage corn is the dominant feed for the dairy industry. At present, the area of wheat / silage maize - combination of grain and grain planting in Shanghai suburbs has reached tens of thousands of mu, but little research has been done on the cultivation of silage maize and the yield is not high and unstable. In recent years, the author carried out experimental research on high-yielding cultivation techniques of silage maize. This paper focuses on the preliminary evaluation of variety test evaluation. I. Materials and Methods (I) The varieties tested were golden queens and Shanghai Academy of Agricultural Sciences Shanghai No. 5, Jiangsu Agricultural College M_5P, Nanjing soil species defect deep, Liaoning Academy of Agricultural Sciences Liaoyuan No. 1, Guangxi Maizhong Mohs 1 comparative test.
