粤北地区(韶关)葡萄园土壤理化指标及碳储量剖面分布研究
Study on Soil Physicochemical Properties and Carbon Storage Profile Distribution of Vineyards in Northern Guangdong Province(Shaoguan)
摘要
Abstract
In order to understand the soil fertility status in the main vineyards in northern Guangdong(Shaoguan),13 vineyards were sampled at three depth(0-20,20-40,40-60 cm)to analyze soil bulk density(BD),pH,physical clay content(PC),organic matter(OM),total nitrogen(TN),alkali hydrolyzed nitrogen(AN),available phosphorus(AP),available potassium(AK),exchangeable calcium(CCa),exchangeable magnesium(CMg),available zinc(AZn),available boron(AB)content,organic carbon(OC),organic carbon density(Si),and total organic carbon density(TSi).The results showed that:the average BD of tested vineyard soil was 1.46 g·cm-3,the PC content was 35%,according to the national soil survey classification stardard,the average level of other indicators:the soil pH,OM,TN,AN,CMg,and AB were at level 4,the AP,CCa and AZn were at level 1;the AK was at level 2;and the proportion of vineyard with soil pH,OM,TN,AN,AP,AK,CCa,CMg,AZn,and AB belonging to levels 4-5 were 76.93%,84.62%,92.31%,92.31%,7.69%,23.09%,0,84.62%,0,and 100%,respectively;With the increase of soil depth,soil pH generally showed an upward trend,while OM,TN,AN,AP,OC,and Si showed a downward trend.Most bases,such as AK,CCa,CMg,AZn,and AB,showed a downward trend.Si was significantly negatively correlated with soil BD and depth,significantly positively correlated with soil TN,AN,AP,and AB,while showing a significantly positive correlation with AZn.Conclusion:the average level of AP,AZn,AK,and CCa were rich,the average levels of soil pH,OM,TN,AN,CMg and AB were poor,and targeted improvement were needed.关键词
