Study on the Soil Nutrients at Apple Orchard in Chengcheng County
摘要
Abstract
To make reasonable fertilization scheme based on testing nutrient distribution of soil at apple orchard ,soil among the 86 apple orchards at ChengCheng county was choosed as the research area and these elements were determined ,including organic mat-ter,available phosphorus ,total nitrogen and available potassium content and variation level.Results show that soil organic matter and total nitrogen content are in the lack of stater ,rapidly-available potassium in the abundant state ,and the effective phosphorus in the medium or the richstate at Chengcheng county.The variation level of nutrients from large to small for these towns were available phosphorus(44.06%),rapidly-available potassium(24.52%),organic matter(16.39%),total nitrogen(13.63%).And apart from the rapidly-available potassium of soil at Siqian town and soil organic matter and total nitrogen content at Jiaodao town are weak vari -ation.the nutrient distribution are characterized by medium variation for the rest four of villages and towns .关键词
