为解决粉煤灰利用难题,本试验通过向粉煤灰中添加奶牛场垫料,并对混合基质种植的3种蔬菜(雪里蕻、白菜、胡萝卜)的生长状况进行评价,探讨粉煤灰与奶牛场垫料混合配成的不同处理基质对蔬菜苗期生长的影响。试验以粉煤灰为对照(CK),粉煤灰和奶牛场垫料混合比例(干质量之比)分别为0∶10、2∶8、4∶6、6∶4、8∶2、10∶0。试验结果表明:以粉煤灰为主、奶牛垫料为辅配制成的新型基质可以满足蔬菜生长需求;同时说明碱性基质同样适用于蔬菜的生长;粉煤灰与奶牛垫料混合质量比为2∶8~4∶6时较适合蔬菜生长。
In order to solve the problem of utilization of fly ash, this experiment evaluated the growth status of three kinds of vegetables grown in the mixed substrate (Xueliu, cabbage, carrot) by adding the litter of dairy cattle to the fly ash, Effect of Different Treatment Substrates Mixed with Field Lining on the Growth of Vegetables at Seedling Stage. In the experiment, fly ash was used as control (CK), and the mixture ratio of fly ash and dairy litter (dry mass ratio) was 0:10, 2: 8, 4:6, 6:4, 8:2, : 0. The results showed that the new matrix made of fly ash and cow dunnage supplements could meet the needs of vegetable growth. At the same time, the basic matrix was also suitable for the growth of vegetables. The mass ratio of fly ash and cow bedding was 2:8 ~ 4:6 more suitable for vegetable growth.
