Assessment for Soil Quality Status in Longan Orchard Fertilized with Laying Hen Feces
摘要
Abstract
To evaluate the soil quality status in longan orchard fertilized with laying hen feces, the generation and management of the laying hen feces in layer farm were investigated, chemical indexes such as organic matter, total nitrogen, total phosphorus, Cu and Zn of soil in longan orchard were determined, and the effects of laying hen feces on longan orchards soil were also measured. Results showed that the equivalent load of feces on soil in longan orchard was 19.14 t ·hm-2, which did not exceed the warning value of equivalent load of feces on soil counted by nitrogen. Chemical indexes of soil in longan orchard fertilized with laying hen feces were higher than those indexes in rubber plantation which did not fertilized with laying hen feces, but there wasn't significant difference in spring, summer, autumn and winter. The chemical indexes such as organic matter, total nitrogen, total phosphorus, Cu and Zn of soil in longan orchard were 18.71 g·kg-1, 0.97 g·kg-1, 0.79 g·kg-1, 19.65 mg·kg-1 and 43.05 mg·kg-1 respectively on average in a year, which were significantly higher than those in rubber plantation. The individual pollution index of copper and zinc in four season were both less than 1, belonging to the security level. Because only 2% of total fresh laying hen feces was fertilized in Longan orchard, there were still risks of environmental pollution. Basis was provided for assessing the risk of environmental pollution and the rationality of laying hen farm pattern with fruit garden from this article.关键词
