A Comparative Study on the Growth of Four Excellent Peach Varieties in Purple Soil
To explore the growth differences of different peach tree varieties in purple soil,this study took Xiang-shi Township,Hengyang City,Hunan Province as the experimental site,and planted four peach varieties:"Jinxiang Jade Yellow Peach","Yanling Yellow Peach","Pig Blood Peach",and"Jingxiang Peach".Three fertilization meth-ods were designed,including organic fertilizer,biological bacterial fertilizer,and organic fertilizer+compound fertilizer.The survival rate and various growth indicators of different four excellent peach varieties in purple soil areas were evaluated.The effects of different peach tree varieties and fertilization methods on the growth status of peach trees are compared.The results showed that the survival rates of four different peach varieties were all a-bove 85%.The survival rates of peach trees treated with organic fertilizer and compound fertilizer(A3,B3,C3 and D3)were relatively high,at 98%,96%,96%,and 96%,respectively.Among them,the survival rate of"Jinx-iang Yuhuang Peach"was relatively high;The growth indicators of peach trees in the treatment groups(A3,B3,C3,and D3)treated with organic fertilizer and compound fertilizer were relatively good,and the average annual growth of peach trees in terms of height,diameter,and crown width was also relatively high.The results show that in the purple soil area of Hengyang,the preservation rate of"Jinxiangyu"and"Jingxiang"peach is high and their growth condition is good.The fertilization method of organic fertilizer+compound fertilizer is more advanta-geous than other fertilization methods.This study provides a theoretical basis for scientific afforestation of differ-ent varieties of peach trees on purple soil.
