增施生物有机肥对盐碱土壤养分的影响
Effect of Bio-organic Fertilizer Application on Nutrients in Saline-alkaline Soil
摘要
Abstract
Field experiments were carried out in Western Jilin to study the effect of different amounts of bio-organic fertilizer application on organic matter content, nutrient content and pH value in saline-alkaline soil. Results showed that soil pH value was efficiently decreased with bio-organic fertilizer treatment. The detected values on soil properties of organic matter content, total nitrogen content, available potassium content and pH value, which reached the minimum during July, decreased early and then increased late from June to September. In the saline-alkaline soil of the three experimental groups treated with biological organic fertilizer, soil pH value was significantly lower and the values of content of organic matter, total nitrogen, available phosphorus and available potassium were higher than those of the control group. The change range of these detected values on soil properties increased gradually with the increase of adding amount of bio-organic fertilizer application.关键词
