摘要
为解决新会陈皮加工产生的大量废渣(液)污染环境的问题,以陈皮加工废渣(液)为原料制成复方柑液有机碳肥,并进行系列盆栽、大田肥效试验。试验结果表明:施用有机碳肥后,叶菜类(小白菜、油麦菜等)增产18.6%~71.0%;除了大田玉米复方柑液有机碳肥A 3处理外,其他处理玉米增产12.9%~14.2%;作物的叶绿素含量升高,有利于促进光合作用。叶菜类蔬菜施用C/N(质量比)为3.2~3.5的复方有机碳肥效果较好,谷物类施肥C/N在2.1~3.2为宜;有机碳的肥效与作物种类、肥料的C/N有关。这为农产品加工废物的治理提供了资源化利用的新途径。
In order to solve the environmental pollution problem caused by a large amount of waste residue(liquid)produced by Xinhui tangerine peel processing,compound orange liquid organic carbon fertilizer is prepared by using tangerine peel processing waste residue(liquid)as raw materials,and a series of potted and field fertilizer efficiency tests are carried out.The test results show that after applying organic carbon fertilizer,the output of leaf vegetables(pakchoi,leaf lettuce,etc.)increases by 18.6%to 71.0%;with field maize,except for compound orange liquid organic carbon fertilizer A 3 treatment,the output of other treatment maize increases by 12.9%to 14.2%;the increase of chlorophyll content of crops is conducive to promoting photosynthesis.For leafy vegetables,the application of compound organic carbon fertilizer with a C/N(mass ratio)of 3.2 to 3.5 has better effect,and a C/N ratio of 2.1 to 3.2 is more suitable for cereal fertilization;the efficiency of organic carbon fertilizer is related to crop types and C/N ratio of fertilizer.This provides a new way of resource utilization for the treatment of agricultural products processing waste.
