摘要
2014—2015年,在泰州市姜堰区张甸镇梅垛村研究了沼液对小白菜产量及土壤质量的影响,结果表明:在一定范围内增加沼液施用量,小白菜的产量和干物重也随之增加,超过适宜值则下降。土壤中有机质和砷含量基本随沼液施用量的增加而增加。综合各因素,沼液施用量为1 500 m L时,小白菜产量最高,砷的含量未超出土壤环境质量标准。
In 2014--2015 ,this paper researched the influence of biogas slurry on Chinese cabbage yield and soil quality in Meiduo Village, Zhangdian Town, Jiangyan District,Taizhou City. The results showed that if increasing biogas slurry application amount within certain limits, Chinese cabbage yield and dry weight would also increase accordingly, and they would decline if exceeding appropriate value. Basically, organic matter and arsenic content in soil increased with the increase of biogas slurry application amount. Integrating various factors,when biogas slurry application amount was 1 500 mL, Chinese cabbage had the highest yield and arsenic content didn＇t exceed soil environmental quality standards.
