本试验以新台糖22号(T22)为对照,对园林2号(Y2)、园林3号(Y3)、园林6号(Y6)三个引进甘蔗新品种春植蔗的农艺性状和经济性状进行了田间试验研究。结果表明:Y6的综合表现最优,优良性状较多,蔗茎产量达到T22水平,分别比Y2、Y3增产17.3%和15.8%,达到5%差异显著水平;Y2、Y3的蔗茎产量显著低于T22。Y2、Y3、Y6成熟期的蔗糖分均低于T22,差异幅度在0.38%～0.11%(绝对值)之间。根据农艺性状和经济性状模糊综合评价,品种优劣排序为:Y6>T22>Y2=Y3。Y3和Y6的脱叶性最好,表现为自动脱叶或极易脱叶。
In this experiment, the new sugarcane variety T22 was used as the control to evaluate the agronomic and economic characters of three new sugarcane varieties of spring sugarcane introduced in Y2, Y3 and Y6 Field experiment study. The results showed that: Y6 showed the best comprehensive performance with more excellent characters and the yield of cane stem reached T22 level, which increased by 17.3% and 15.8% respectively than Y2 and Y3, reaching a significant difference of 5%; At T22. The sucrose content in mature stage of Y2, Y3 and Y6 was lower than that of T22, and the difference ranged from 0.38% to 0.11% (absolute value). According to the fuzzy comprehensive evaluation of agronomic traits and economic traits, the order of varieties was Y6> T22> Y2 = Y3. Y3 and Y6 the best defoliation, manifested as automatic defoliation or easily defoliate.
