生物炭改土对植烟土壤理化性状动态变化的影响
Effect of Biochar for Soil Amendment on Dynamic Variation of Tobacco Soil Physical and Chemical Properties
摘要
Abstract
The pot experiments were conducted to study the influences of different biochar application levels on soil bulk density , pH value , organic matter and available nutrients contents and their change rules during tobacco growing period .The results showed that 1~2 kg biochar application in every pot could reduce the soil bulk density significantly by 12%~20%, but increased the pH value .The content of organic matter in soil was linearly correlated with the biochar application level .The application of Biochar reduced the con-tent of alkaline nitrogen in soil and restricted the nitrogen availability .Its application could improve the con-tent of available potassium in soil and make soil have the ability to continuously provide potassium , but had no significant effect on available phosphorus content .关键词
