豆科作物秸秆还田对毛桃幼苗生长及养分吸收的影响
Effects of legume crop straw returning to soil on growth and nutrient up-take of peach seedlings
摘要
Abstract
In order to improve the comprehensive utilization of crop straws,and to screen the suitable types of legume crops for returning to the field,this study took no application of straw as the control(CK),set four legume crops(Lablab purpureus,Vigna unguiculata,Vigna um-bellata and Phaseolus vulgaris)straws as treatments,and the effects of applying different legume crop straws on the growth and nutrient absorption of peach seedlings were studied.The results showed that the straw of L.purpureus increased the root and shoot biomass of peach seedlings by 8.62％and 6.91％,respectively,compared with CK,while the straw of V.umbellata decreased the shoot biomass of peach seedlings by 7.70％.Compared with CK,the straw of L.purpureus increased the contents of chlorophyll a,chlorophyll b,and carotenoids in the leaves of peach seedlings by 19.06％,22.12％,and 18.78％,respectively,the straws of L.purpu-reus,V.unguiculata and P.vulgaris significantly increased the antioxidant enzyme activities of peach seedlings,while the straw of V.umbellata decreased the activities of peroxidase(POD),catalase(CAT),and ascorbate peroxidase(APX)of peach seedlings by 4.99％,5.23％,and 10.95％,respectively.The application of straws of four legume crops increased the total nitrogen contents in roots and shoots of peach seedlings,and the effect of V.umbellata straw was the most significant.The straws of V.umbellata and P.vulgaris also increased the total phosphorus content in roots of peach seedlings.In addi-tion,the soil alkali-hydrolyzable nitrogen content and root total nitrogen content showed highly significant positive correla-tion with aboveground total nitrogen content.The root total phosphorus content,soil available phosphorus content and root total potassium content showed highly significant positive correlation with aboveground total phosphorus content.The soil available phosphorus content and shoot total phosphorus content were in significant positive or highly significant positive cor-relation with aboveground total potassium content.Therefore,the application of lentil straw is the most beneficial to the growth of peach seedlings.关键词
