【摘要】 对贵州省云新系列、本地泡核桃及薄壳山核桃的产量进行了初步调查,并分别研究了主要生长性状与产量的相关性,结果表明:8年的云新核桃平均株产量为1. 29kg,9～12年的本地泡核桃的平均株产量为5. 52kg,7年的薄壳山核桃平均株产量为2. 91kg;云新核桃的冠幅与产量呈显著正相关,本地泡核桃的树龄与产量呈极显著正相关,薄壳山核桃树高、冠幅、树径与产量都呈显著正相关。并且建立了多元线性回归方程,为制定抚育管理技术措施提供参考。更多还原

【Abstract】 The yields of Juglans Sigillata( YunXin),Juglans Sigillata( Local) and Carya illinoensis( Pecan)in Guizhou Province were investigated. And the correlation between main growth characters and yield was analyzed separately. The results showed that the average yield of Juglans Sigillata( Yunxin) of 8 years was 1. 29 kg,Juglans Sigillata( Local) of 9-12 years was 5. 52 kg,and Carya illinoensis( Pecan) of 7 years was 2. 91 kg. The Juglans Sigillata( YunXin) had a significant positive correlation between crown width and yield,and the age and yield of Juglans Sigillata( Local) were significantly positively correlated. The height,crown width and tree diameter of Carya illinoensis( Pecan) were all significantly positively correlated with yield. And the multiple linear regression equations were established to provide reference for formulating tending measures.更多还原
