复合肥料养分含量和配比与农业需求的匹配度研究
Studies on the matching degree of both nutrient content and proportion of compound fertilizers with agricultural needs
摘要
Abstract
To explore the adaptability of the nutrient content and proportion of compound fertilizers in circulation with the needs of agricultural production,the compound fertilizer products circulating in the market of the main grain producing regions are taken as study subjects.The quantitative analysis and comparative study methods are adopted to analyze the correspondence of the labeled contents and proportions of compound fertilizers with the recommended contents and formulas.The results show that:1)There is low compatibility between the compound fertilizer content and the agricultural demand,and the excessive nutrient content is common.In wheat,rice and maize production regions,the matching degrees of comprehensive content of nitrogen,phosphorus,and potassium are 51.29％,37.44％and 30.50％,respectively.The compound fertilizer nutrient content is higher than the recommended nutrient content on average,and there is need to reduce the package size and adjust the formula;2)There is low compatibility between the compound fertilizer labeling proportions with recommended formulas.In wheat,rice and maize production regions,The comprehensive nutrients of nitrogen,phosphorus and potassium in compound fertilizers are in line with the recommended formula ratio of 1.55％,5.16％and 0.57％,respectively;3)The nutrient proportions of compound fertilizers circulating in crop production areas are unreasonable.In,wheat,rice and maize production region,the market circulation of compound fertilizer nutrient proportions on the whole is as follows:N proportions are higher than the recommended formula,and P proportions are lower than the recommended formula.Therefore,it is necessary to adjust the proportion of nutrients by reducing the proportion of N.In conclusion,there is an urgent need to promote and implement the real name and quota systems for fertilizers,strengthen supervision over compound fertilizers,improve compound fertilizer products from the perspective of fertilizer industry supply,and promote the rational supply of compound fertilizers in order to to improve the matching degree between compound fertilizers and agricultural production demand.关键词
