Influencing Factors Of Fruit Weight And Model Construction Of Xanthoceras Sorbifolium In Different Cultivation Areas

Xanthoceras sorbifolium Bunge is one of the important edible oil tree species in China,and it is also a kind of landscaping tree with high ornamental value.In this paper,the factors influencing the fruiting quantity of Xanthocera sorbifera fruit in four different cultivation areas in Inner Mongolia and Jilin were studied comprehensively,and the production model of xanthocera sorbifera fruit was established.The aim of this study was to provide scientific theoretical basis for the high yield and fruiting of Xanthoxene fruit,increase the effect of fruit observation,and give full play to the value of ornamental and afforestation.The results show that:(1)The results showed that the total number of fruit sets in QG,Wengniute Banner,TN,Alukeerqin Banner were in the following order: QG > WQ > TN > AQ.(2)different cultivated area soil data,to analyze its content in the soil N,P,K and organic matter content in different soil layer,the results show that the different growing areas in the soil containing N,P,K and organic matter content in different soil layer in different,found that the main rule for increases with the increase of soil depth,there are a few result is contrary to law,The soil N,P,K and organic matter contents in the soil decreased with the increase of soil depth,possibly due to climatic reasons.In addition,the effect on the fruiting quantity of Xanthocorpa xanthocorpa is different,which needs to be analyzed according to the specific situation in the field.By analyzing the effect of p H value in different soil layers in different regions on fruit setting,it was found that acidic soil promoted fruit setting.(3)Correlation analysis was made between tree growth traits and fruit set quantity.The results showed that the average DBH,height and crown width of crown fruit in Wengniute Banner area were significantly higher than those in other areas(P<0.05).There was a positive correlation between DBH,tree height and crown width on fruit set in different areas(P<0.05).(4)The correlation analysis between stand factors and set amount showed that the relationship between stand density and set amount was TN>AQ>QG>WQ,but there was no significant correlation between stand density and set amount.(5)A suitable model was selected through model analysis of soil factors,climate factors,tree growth factors and seed setting quantity.Data analysis showed that three producing areas(I,II and III)were finally obtained through analysis of annual precipitation,annual temperature range of crown and seed setting quantity of crown fruit.
