The breeding and cultivating techniques of Ligustrum robustum

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.
