以桂糖 1 1号和新台糖 1 6号作试验材料 ,分剥叶砍种、剥叶不砍种、不剥叶不砍种 3种砍种处理。试验结果表明 :在干旱条件下 ,桂糖 1 1号剥叶不砍种处理的出苗率高 ,死苗率低 ,不剥叶不砍种处理株高和绿叶数数值最大。在生理生化方面 ,干旱区桂糖 1 1号各处理萌芽期间 ,种茎中氨基酸含量 1 4 .2 5～ 1 8.0 0 mg/g Fw,还原糖含量 1 .0 6～ 2 .5 8mg/ g Fw,新台糖 1 6号在干旱区各处理则相反 ,种茎中氨基酸含量 1 .5 0～ 2 .6 3mg/ g Fw,还原糖含量达 1 8.75～ 2 9.5 3mg/ g Fw,种茎近于中度肋迫 ;而桂糖 1 1号在干旱区剥叶不砍种、不剥叶不砍种处理的自然饱和亏缺值与非干旱区各处理基本相同 ,而新台糖 1 6号的则比对照大大提高。因此 ,丘陵坡地应选用桂糖 1 1号剥叶不砍种技术
Using Guitang No.1 No.1 and Xintaanduixi6 as test materials, the leaves were cut, the leaves were removed, the leaves were not cut, and three kinds of cuttings were not cut. The results showed that in the drought conditions, Gui Tang 1 1 stripped leaves without cutting the emergence of high rate of seedlings, dead seedling rate is not stripped leaves without cutting the highest number of plant height and green leaf number. Physiological and biochemical aspects, during the germination of Guitang No.1 1 in arid areas, the amino acids in the stems ranged from 14.25 to 8.00 mg / g Fw and the content of reducing sugars was 1.06-2.58 mg / g Fw and Xintai66 on the contrary, the contents of amino acids in the stems were 1.55-2.63 mg / g Fw and the content of reducing sugars was 1 8.75-2.95 3 mg / g Fw However, the natural saturation deficit value of Guitang No.1 1 in stripping leaves in the arid area was not significantly different from that in the non-arid area. However, Then greatly increased compared with the control. Therefore, hilly slopes should use Gui sugar 1 1 stripping leaves not cutting technology
