改良剂对旱地红壤pH和有效P含量的影响
A study on effects of amendments on soil pH and available phosphorus of upland red soil
摘要
Abstract
Upland red soil in Southern China is usually found to be high in acidity and low in the content of available phosphorus. Therefore,this paper conducts an experiment to study the effect of soil modifiers (biochar and calcium peroxide)on soil pH and soil available phosphorus. The results show that soil pH rises to different degrees and the contents of available phosphorus are increased after the application of biochar and calcium peroxide,and the best effect is obtained from the combined application of both ingre-dients,with C1Ca1(biomass char 758 kg / hm2 and calcium peroxide 61 kg / hm2 )being the best treat-ment. Under the application of amendments,soil available phosphorus has a significant correlation with the soil pH in 0 - 40 cm soil.关键词
