我县地处曲靖地区东南部,冬季阴雨多,夏季气温较高,降雨量和空气相对湿度大,日照短,光照较强。罗雄坝海拔1482.7米,年平均气温15.1℃,月平均最高气温21.1℃,极端最高气温35.7℃,全年日照时数1675小时,日照率38％,年降雨量1741毫米,空气相对湿度81％。 1981年,我县从曲靖引种细绿萍,开展试验、示范工作。为了摸清细绿萍在我县坝区不同季节的繁殖速度以及繁殖率与气象要素之间的相关性,我们从1981年元月开始进行细绿萍繁殖率的测定工作,现将测定结果初报如下。一、测定方法按地区农科所拟定的方法,以本地萍为
My county is located in the southeast of Qujing, rainy in winter and more in summer, higher temperatures, rainfall and air relative humidity, short sunshine, strong light. Luo Xiong dam elevation of 1482.7 meters, the annual average temperature of 15.1 ℃, the monthly average maximum temperature of 21.1 ℃, the extreme maximum temperature of 35.7 ℃, annual sunshine hours of 1675 hours, sunshine rate of 38%, annual rainfall of 1741 mm, air relative humidity of 81% . In 1981, my county introduced fine green Ping from Qujing to carry out experiments and demonstration work. In order to find out the fine lupin in my county dam season reproduction rate and reproduction and the correlation between meteorological factors, we started from January 1981 for the measurement of fine lupine reproductive rate, the determination of early Reported as follows. First, the determination method According to the method developed by the local agricultural science, with local Ping as
