脱毒果蔗旱地栽培高产机理研究

在有微喷灌条件的旱地上栽培果蔗,研究脱毒果蔗在旱地生长生理情况。结果表明:脱毒果蔗单位面积产量比未脱毒果蔗增产23.45%;脱毒果蔗叶绿素含量为2.30 mg/g,比未脱毒果蔗的1.57 mg/g提高46.62%;叶片相对含水量为102.46%.mm,比未脱毒果蔗97.97%.mm提高4.59%;脱毒果蔗伤流量为776.19 mg/h.cm2,比未脱毒的609.02 mg/h.cm2提高27.45%;脱毒果蔗单株根系鲜重135.47 g、干重79.12 g,分别比对照增加22.96%、15.02%;后期的完全展开绿叶(功能叶片)脱毒果蔗比对照多1.3片,增加20.00%;单株绿叶重脱毒果蔗0.458kg,比对照增加36.31%。

Study on the high yield management of virus-free chewing cane with dry-land cultivation

Under the micro-sprinkler irrigation condition,the growth physiological of virus-free chewing cane(VCC) cultivated in dry-land was researched.The results showed that compared to the control was not done any virus procedure,cane yield was increased 23.45%;the cane leaves chlorophyll content of VCC(2.30 mg/g) was higher than control(1.57 mg/g) by 46.62%;the leaf relative water content of VCC(102.46%mm) was higher than the control(97.97% mm) with 4.59%.The amount bleeding sap of VCC(776.19 mg/h·cm2) was over than control(609.02 mg/h·cm2) by 27.45%mg/h·cm2;the fresh and dry weight of VCC root were 135.47 g and 79.12 g,were increased 22.96% and 15.02%,compared with the control,respectively.On last growth stage,the number of completely unfold green leaves(functional leaf) of VCC was more than control by 1.3 leaves and increased with 20.00%.The green leaf weight of VCC was 0.458kg/plant higher than control with 36.31%.
