摘要
连续 3年大白菜定位试验结果表明 ,垃圾堆肥用量的增加与大白菜产量呈正相关 (r=0 .9445 * *) ,平均增产 2 2 .1 t/hm2 ,增产幅度达 2 3.0 %~ 70 .0 % ,增值6 6 30元 /hm2 ,经济效益十分明显。施用垃圾堆肥使大白菜品质有很大的改善 ,粗纤维含量降低 1 3%~ 35 % ,硝酸盐含量减少 2 0 %左右。
The effect of continuous application of waste compost on the Chinese cabbage was investigated for three years.The result indicated that there was a close correlation between the amount of wast compost application and yield of Chinese cabbage(r=0.9445 ).The average increasing output of Chinese cabbage was 22.1 t/hm 2,and range from 23.0% to 70.0%,compared with ck treatment.It showed efficiency for enhancing income,mean income was 6 630 yuan/hm 2.The quality of Chinese cabbage improved by applying waste compost was clearly,the coarse fiber content decreased range from 13%~35%,and the nitrate contend decreased about 20%.
