粗壮女贞繁殖与栽培技术研究

The breeding and cultivating techniques of Ligustrum robustum

  • 摘要: 对粗壮女贞繁殖与栽培技术的研究结果表明,地窖沙藏种子处理3月2日播种,4月下旬即可萌发且发芽率达80%,1年生平均株高62.3cm,平均地径0.58cm;无性繁殖以秋季扦插效果较好,野生穗条短枝成活率达43.7%,分别比春季、夏季扦插高13.7%和38.7%;扦苗萌条短枝成活率达88.5%,分别比春季、夏季扦插高46.0%和73.7%;退耕还林地种植其株行距0.8m×1.5m~0.6m×1.5m,种植密度为0.8325~1.1100万株/hm2,荒山荒地造林则采用2m带宽,株距0.6m,种植密度8325株/hm2较为合适。

     

    Abstract: The breeding and cultivating techniques of Ligustrum robustum were studied.The results show that the seeds stored in the sand in cellar can be sown in March 2 and sprouted in the last ten day of April with a germination rate of 80%, an annual and average plant height of 62.3cm and an average radical diameter of 0.58cm;as the asexual breed,the effect of cuttage in autumn is better and the survival rate of short branches of wild spikes reaches 43.7% being 13.7% and 38.7% higher than those in spring and summer;the survival rate of germinated short branches of cuttage in autumn is 88.5% being 46% and 73.7% higher than those in spring and summer.On the forest land returned from the cultivated land,its suitable cultivated distance of plantlets and rows is from 0.8m×1.5m to 0.6m×1.5m and its suitable cultivated density is 8325~11100 plantlets/hm2 while on the barren hill side and uncultivated land ,they are 0.6m×2m and 8325 plantlets/hm2 respectively.
