对讷河9 a生各沙棘种源的树高、地径、冠幅、保存率等进行相关分析、方差分析及LSD检验,选择出内蒙的凉城种源、赤峰种源和山西的右玉种源为最佳生态种源;通过对各沙棘种源雌株的平均树高、地径、冠幅、雌株比、产果量进行多元回归分析,求出各性状与产果量之间的通径系数,从而求出各沙棘种源的综合指数,通过各种源的综合指数及产果量的LSD检验结果,寻找出最佳经济种源为内蒙凉城种源、赤峰种源和山西的右玉种源,因此,凉城种源、赤峰种源和右玉种源为黑龙江省西部地区的最佳生态经济沙棘种源,其树高、地径、.冠幅.产果量的遗传增益分别为17.7%、14.5%、15.5%、41.6%.
Correlation analysis, variance analysis and LSD test were carried out to analyze the tree height, diameter, crown width and preservation rate of Hippophae rhamnoides provenance in 9 years old in Nehe. The Liangcheng provenance, Chifeng provenance and Shanxi right jade species Source was the best ecological provenance. By multivariate regression analysis of the average tree height, diameter, crown width, female plant ratio and yield of each seabuckthorn plant, the relationship between the traits and fruit yield Through the LSD test results of the comprehensive indexes of various sources and fruit yield, we found out that the best economic provenance was Inner Mongolia Liangcheng provenance, Chifeng provenance and Shanxi Therefore, the provenances of Liangcheng, Chifeng and Youyu were the best eco-economical seabuckthorn provenance in the western region of Heilongjiang Province, and the tree height, diameter, crown width, fruit yield The genetic gains were 17.7%, 14.5%, 15.5% and 41.6% respectively.
