天津地区蔬菜种植废弃物产生情况初步调查

The Quantity of Vegetable Waste in Tianjin:A Preliminary Investigation

为了掌握天津地区蔬菜种植废弃物的产生量及资源化可行性情况,通过调查测定出黄瓜、西红柿、茄子、菜花和其他蔬菜种植废弃物的平均产生量和养分,结合种植面积,计算出天津地区蔬菜种植废弃物平均产生量,其中黄瓜、西红柿、茄子、菜花和其他蔬菜产生的种植废弃物分别是64.62、34.76、29.14、41.03、38.61 t/hm^2,蔬菜每公顷平均产生种植废弃物41.63 t,基于蔬菜年复种面积10万hm^2,天津地区年产种植废弃物为416.3万t。对种植废弃物所含成分检测分析可知,N、P、K总养分在4.07%~7.65%之间,重金属含量远远低于有机肥农业行业标准要求。结果表明,蔬菜种植废弃物是一种资源丰富、养分充足及无害的有机肥料资源。

The paper aims to master the quantity of vegetable waste and the feasibility of resource utilization in Tianjin.We determined the average quantity and nutrient content of the waste of cucumber,tomato,eggplant,cauliflower and other vegetables based on the planting area.The results showed that：the average quantity of vegetable waste was as follows：cucumber（64.62 t/hm2 ）,tomato（34.76 t/hm2 ）,eggplant（29.14 t/hm2 ）,cauliflower（41.03 t/hm2 ）,and other vegetables（38.61 t/hm2 ）;the average quantity of vegetable waste was 41.63 t/hm2 ,the annual output of vegetable waste was 4.163 million tons based on 100 thousand hm2 of the annual multiple cropping area of vegetables in Tianjin.The measurement of nutrients content showed that：the total nutrient of N,P,K was between 4.07% -7.65%,and the content of heavy metals was far lower than the agriculture industry standard of organic fertilizer.The results indicated that：the vegetable waste was a kind of organic fertilizer with rich resources,adequate nutrient and innocuity.
