Contents and Availability of Trace Elements in Orchard Soil in Wensu County of Xinjiang
摘要
Abstract
[Objective] By measuring effective state content of the trace elements Cu,Fe,Zn,Mn and B in orchard soils in Wensu County of Xinjiang,this project aims to make clear the trace elements distribution in this area and explore the correlation of effective state of soil trace element content,soil organic matter content and pH,and perfomr effectiveness evaluation of the soil.[Method]In 2015 year,through the sample investigation of forest fruit in about 0.8 million mu area in Wensu County,140 samples from 1,300 sample points were chosen according to the fruit distribution,tree-age and soil characteristics to determine the effective content of trace elements Cu,Fe,Zn,Mn and B,and also,the effectiveness evaluation of trace elements in this area was carried out.[Result]The results showed that:the average contents of effective Cu,Fe,Zn,Mn and B were 1.5,12.0,2.2,4.9 and 0.9 mg/kg in the orchard soil trace element of Wensu County.The content of effective Cu,Fe and Zn were rich,effective B was moderate,effective Mn was extremely scarce.Among them,the soil trace element Cu,Fe,Mn and B belonged to medium variation,trace element Zn belonged to strong variations.Orchard soil effective content of Cu,Fe and Mn were very significantly positively correlated with organic matter content(P =0.000 < 0.01)in Wensu County.The content of effective Cu and pH value were of extremely significant positive correlation(P=0.003 < 0.01).According to the evaluation index of soil effective trace element in the orchard soil of Wensu County,element contents Cu,Fe and B content were extremely rich,Zn and Mn contents were relatively poor.The single factor effectiveness index of available trace element showed that the orchard soil effective state contents Cu,Zn and B were higher than the critical value,Fe and Mn were significantly lower than the critical value,the average sequence was: Cu > Zn > B > Fe > Mn in Wensu County.The effective state trace element comprehensive index of the top five sample areas were as follows: Rice Farm(7.36)> Qiagelake Township(5.89)> Arele Town(5.78)> Gugedai Pasture(5.65)> Tumuxiuke Town(5.13).The average of comprehensive index was 4.04.[Conclusion]To sum up,orchard soil trace elements Cu,Fe and B content are plentiful,Zn and Mn are relatively scarce,so,it is recommended that when applying fertilizer containing Zn and Mn should consider the local condition in the soil in this area.关键词
