Abstract:

To reveal the soil factors that formed the quality characteristics of Hebei chestnut,54 typical chestnut orchards from 8 counties in Hebei Province were selected as the objects,and the contents of 9 mineral elements in the soil were studied by using significance,correlation and principal component analysis.The results showed that there were no significant differences in contents of Mg and Na,but there were significant differences in N,P,K,Ca,Fe,Mn and Cu contents in the soil of chestnut plantations in the main chest nut production areas.The N content in the soil of chestnut orchards was generally below the level of 3,and the P content was generally above the level of 3.The K content was generally at a low level,which was below the level of 5.The correlation of the contents of metal elements such as Ca,Mg,Fe,Mn,Cu and Na were significantly correlated with each other in soil.They were also significantly correlated with P element,and the correlation with N content was generally weak.Principal component analysis showed that mineral elements in the first 3 principal components reflect the total information content 73.521%.The contribution rate of the first principal component accounted for 44.678%,and the elements which included Ca(0.871),Cu(0.840),Fe(0.809)and Mg(0.806)were the main factors.It showed that the metal trace element content contributes more to the principal component.The comprehensive score was based on the mineral elements content of different chestnut orchards,which decided the order of high and low.The highest score was in Qianxi County(0.591 8).The ranking of the soil quality in the main chest nut production areas was:Qianxi>Qinglong>Xinglong>Kuancheng>Shahe>Zunhua>Xindu>Funing.To sum up,it is confirmed that the comprehensive scores of metal elements contents such as Ca,Mg,Fe,Cu can be used to evaluate the soil quality by using principal component analysis.It was advisable to select high K and low P compound fertilizer,and it was recommended to apply multiple elements mixed fertilization as a supplementary measure to improve the soil quality level of chestnut orchards.
