番木瓜缓释肥料的养分释放特性研究
Study on Nutrient Release Characteristics of Papaya Slow-Release Fertilizers
摘要
Abstract
[ Objective] The experiment aimed to evaluate nutrient release characteristics of four papaya slow-release fertilizers. [ Method] Water extraction method was applied to evaluate nutrient release characteristics of four papaya slow-release fertilizers according to Chinese slow release fertilizer evaluation standard enforced on 2009. [ Result] Nitrogen (N) nutrient preliminary solubility rate of SRF-1 was higher than 15%, potassium (K) nutrient preliminary solubility rate of SRF-2 was also higher than 15%. The N, phosphorin(P) and K nutrient preliminary solubility rate of SRF-3 and SRF-4 were lower than 15%. 28 days' accumulation release ratio of SRF-3 and SRF-4 were lower than80%,and their 90 days' nutrient accumulation release ratio were higher than 80%. [ Conclusion] The nutrient release characteristics of SRF-3 and SRF-4 were in accordance to the Chinese slow release fertilizer evaluation standard enforced in 2009.关键词
