摘要
[目的]对修剪处理后的牛大力生长性状进行评价,并对比分析修剪处理后生长指标的差异性。[方法]以隆安种源攀援灌木牛大力为研究材料,在南宁市林业科学研究所进行纯作种植,种植2.5年后对其进行生长性状测定和修剪差异分析。[结果]2.5年生的牛大力生长性状存在很大的变异性;牛大力的根重和其他指标都呈极显著正相关,说明地径、蔓重和根数等6个性状生长都会对牛大力的根重起促进作用;由回归分析得出,对牛大力根增重影响较大的为蔓重、根数和最大根径。[结论]攀援灌木牛大力纯作种植在地面到蔓长的1.5 cm处修剪能有效促进其根部的增产。
[Objective]The growth traits of Millettia speciosa after pruning were evaluated,and the differences in growth indicators after pruning were compared and analyzed.[Method]Taking M.speciosa as the research material,pure cropping was carried out in Nanning Forestry Research Institute.After 2.5 years of planting,the growth traits were measured after pruning,the differences in growth indicators after pruning were analyzed.[Result]There was a great variation in the growth traits of the 2.5-year-old M.speciosa.The root weight of M.speciosa was positively correlated with other indexes,the results showed that the growth of 6 traits,such as ground diameter,vine weight and root number,could promote root weight.The regression analysis showed that the main influence factors on the weight gain of M.speciosa roots were vine weight,root number and maximum root diameter.[Conclusion]Climbing shrub M.speciosa,which are pruned at 1.5 cm from the ground to the vine,can effectively increase their roots.
