羊草(Leymus chinensis)是内蒙古天然草场上的主要优良牧草之一。提高羊草的单位面积产量,对增加饲草产量具有一定的实际意义。为探索羊草草场的增产途径,我们用新型植物激素——30烷醇进行了喷施试验,取得了平均增产13.2％的效果。一.试验地自然概况试验地设在内蒙古西苏旗朱日和以东约10里处。草群组成除优势种羊草外,还有针茅、糙隐子草等旱生丛生禾草。草群总盖度40％左右,种饱和度为1平方米9—15种。优势种羊草密度较大,据
Leymus chinensis is one of the finest forages in the natural pastures of Inner Mongolia. Raising the yield per unit area of Leymus chinensis has some practical significance for increasing forage yield. In order to explore the yield-increasing ways of Leymus chinensis pasture, we sprayed with a new plant hormone, 30-alkanol, and achieved an average yield increase of 13.2%. I. Nature of the Experimental Site The experimental site was located about 10 miles east of Zhuri and in the Xisu Banner of Inner Mongolia. In addition to dominant species of grass herd species of grass, as well as Stipa, rough cryptobrasia and other dry bunch Cong grass. Grass cover total coverage of about 40%, 9-15 species of 1 square meters of saturation. The dominant species of sheep density, according to
