红三叶是我省草山建设中重点发展的优质豆科牧草。据有关部门统计,自“六五”期间以来,我省从国内外调进红三叶草种达20万公斤。为了发展我省草种生产,改变依赖进口的局面,1988年,我们对蜂类为红三叶授粉及提高红三叶种籽结实率、产量的途径,进行了深入研究,现将结果报道于后。试验概况我所位于贵阳市南郊,海拔1100米,无霜期259天。年均温15.6℃,大于10℃以上的积温4658.2℃。年均日照时数1412.6小时,年均降雨量1162.5毫米。试验地设在我所牧草园内。土质粘重,黄棕壤,肥力中等,PH 值5.4。
Red clover is our province grass mountain construction focus on the development of high quality leguminous forage. According to statistics from relevant departments, since the “6th Five-Year Plan” period, our province has transferred 200,000 kilograms of red clover from home and abroad. In order to develop grass production in our province and change the situation of dependence on imports, in 1988, we conducted a thorough study on the way that bees pollinated red clover and the seed setting rate and yield of red clover. The results are reported in Rear. Test Profile I am located in the southern suburbs of Guiyang City, 1100 meters above sea level, frost-free period of 259 days. The average annual temperature of 15.6 ℃, greater than 10 ℃ above the temperature 4658.2 ℃. Average annual sunshine hours 1412.6 hours, with an average annual rainfall of 1162.5 mm. Experimentally located in our pasture garden. Soil sticky, yellow brown, medium fertility, PH value of 5.4.
