生物炭肥料主要养分元素含量及其产率的研究
Analysis of Main Nutrient Element Content and Output Rate of Biochar Fertilizer
摘要
Abstract
In order to study the scientific preparation method of biochar fertilizer and choose the suitable biochar fertilizer raw materials,a variety of fruit tree branches,grain and economic crops,vegetable straws in Henan Province were collected as experimental materials.The pyrolysis temperature of above biomass raw materials,the content of nutrient elements in raw materials and fertilizers,and the output rate of fertilizers were analyzed.The results showe that 7 kinds of agricultural and forestry wastes were suitable for making biochar fertilizer.The carbon content of fruit branches was higher than that of grain,economic crops and vegetable straws.The contents of total nitrogen,total phosphorus and total potassium in fruit branches and straw had no fixed change law.The pyrolysis temperature of fruit branches and straw affected the nutrient content of biochar fertilizer,the output rate of biochar fertilizer was the main factor to determine the pyrolysis temperature.The decomposition of raw materials was insufficient when pyrolysis temperature was too low.The yield of biochar fertilizer was low when the pyrolysis temperature was too high.The principal component analysis results of the biochar fertilizer quality showed that eggplant straw,peanut straw and grape branch were more suitable for the production of biochar fertilizer.The research and development of biochar fertilizer production technology can provide technical support for the resource utilization of agricultural wastes.关键词
