于 1998 - 2 0 0 0年选择 12个柱花草Stylosanthesguianensis新种质进行品种比较 ,结果表明 :Mineirao柱花草、GC15 81柱花草年干草产量分别为 116 5 0 0kg/hm2 和 114 2 0 0kg/hm2 ,高于热研 5号柱花草 (9831 1kg/hm2 ) 18 5 0 %和 16 16 % ;抗旱性强 ,在冬春低温干旱季节的干质量占年产量的 2 9 2 5 %和 2 9 15 % ;较抗柱花草炭疽病 ,试验期内平均病级分别为 1 6 7,1 74 ;植株越冬存活率分别为 30 83%和 4 1 6 8% ,耐寒性强 ;茎叶比为 1 0 3和 1 0 7,营养价值丰富 ,营养生长期粗蛋白含量分别为 15 36 2 %和 11 5 5 0 % ,是优良的柱花草新品种。
The comparison of 12 new varieties of Stylosanthes guianensis from 1998 to 2000 showed that the annual hay yields of Mineirao column flower and GC15 81 column flower were 116 500 kg / hm2 and 114 20 000 kg / hm2, respectively , Which was higher than 1850% and 1616% of Trichosanthes gramineus (9831 1kg / hm2). The drought resistance was strong, and the dry mass in the winter and spring low temperature and drought season accounted for 295% and 295% of the annual output %, Compared with the anti-Coltsfoot anthracnose, the average disease grade were respectively 1 6 7,1 74 during the test period; the survival rates of the plants overwinter were 30 83% and 41 86% respectively, with strong cold tolerance; 3 and 1 0 7, rich in nutritional value, the vegetative growth stage of crude protein content were 15 36 2% and 11 5 5 0%, is an excellent new column flower varieties.
