为了给糜子杂交育种和丰产栽培提供资料依据,我们从1978年开始,连续两年对糜子的开花习性进行了观察。观察在伊盟东胜特拉壕公社本所试验农场进行。场址北纬39°50′,东经109°59′,海拔1460.4米,糜子生育期间(5～9月)平均气温15.88℃,总日照1287.1时,总降雨量399.7毫米,糜子田为砂质壤土。观察品种选用当地黄糜子、73—2糜子(新育成功,正在推广)、内糜2号等三个品种。每个品种选择具有代表性的植株4株,观察主穗,从7月10日起,
In order to provide the basis for crossbreeding and high yield cultivation of millet, we started to observe the flowering habits of millet for two consecutive years since 1978. The observation was conducted at the pilot farm of this Institute in Dongsheng Tela moat, Yi Meng League. The site is 39 ° 50 ’north latitude, 109 ° 59’ east longitude and 1460.4 meters above sea level. The mean temperature of the millet during the growth period (May-September) is 15.88 ℃ and the total rainfall is 1287.1 at 399.7 mm. The millet field is sandy loam. Selected varieties of local selection of yellow broomcorn, 73-2 broomcorn (successful breeding is being promoted), Mi Mi 2, and other three varieties. For each variety, 4 representative plants were selected to observe the main ear. From July 10,
