牛大力种源在马尾松林下套种的生长评价
|
摘要
以种植于马尾松(Pinus massoniana)林下的牛大力(Millettia specisoa)种源为研究对象,通过对2年生的生长数据进行统计分析,评价马尾松林下牛大力的生长情况,并初选适于南宁地区种植的优良种源。研究结果表明,马尾松林下2年生牛大力地上部分蔓长平均值为445.82 cm,地径平均值为1.06 cm,蔓重平均值为1.31 kg;地下部分平均根数为5.91根,平均根长为85.02 cm,单株最大根径平均为1.80 cm,单株总根重量平均为440.22 g,单根平均重量的均值为79.58 g,牛大力在马尾松林下生长良好,牛大力不同种源间生长差异显著。通过主成分降维分析,将9个生长指标综合为地下部分生长量、蔓长生长指标、器官分生能力指标、水分及干物质积累指标4个主成分。基于此初选出上林种源、浦北种源为优良种源。
Taking the Millettia speciose provenance, which was planted under the Masson pine, as the researchobject, the growth status of Millettia speciose under the Masson pine was evaluated by analysis with 2-year-oldgrowth data. The superior provenances which were suitable for planting in Nanning area was selected. Theresults showed that average vine length of 2-year-old Millettia speciose in the ground was 445.82 cm, averageground diameter was 1.06 cm, the average weight of vine was 1.13 kg. The average root number was 5.91, theaverage root length was 85.02 cm, the maximum average root diameter of one plant was 1.80 cm, the total rootweight of one plant was 440.22 g, the average single root weight was 79.58 g. Millettia speciose under Massonpine forest grew well, and there were significant differences among different provenances. Based on the PCA,the 9 growth indexes were divided into the following 4 main components: the growth of underground part, thegrowth index of the vine, the index of the capacity of the organism and the index of the moisture and dry matteraccumulation. Based on it, Shanglin provenance and Pubei provenance were selected.
