摘要
本文介绍了以哈尔滨制革厂废水处理站产生的制革活性污泥为基础原料，研制的多元营养育苗钵的理化性质、营养成份和在蔬菜种植中的应用效果。试验说明，使用该钵可增加植物养分来源，促进生长发育，提高蔬菜产量３０％以上。种植茄子，每亩可增加收入１３００元。每吨活性污泥可创利９１．
This Poper deals with the Physical and chemical properties as well as the nutritional ingredients of the multi-nutrient seedling raising pot manufactured by using the activated sludge from the Waste Water Processing Station attached to Harbin Tannery as raw material and its utilization in vegetable cultivation. The results of experiments indicated that when such pot was used in vegetable cultivation, the supply of plant nutrients could be increased, the growth and development of the plant could be promoted and a more than 30% yield increase could be reached. In eggplant cultivation, a income of 300 yuan/per mu could be achieved. One ton of the active sludge could produce an economic profit of 91. 8 yuan.
