采用3因素3水平正交设计,研究腐植酸、沸石和蛭石对设施土壤盐分和白菜生长的影响。结果表明,影响设施土壤盐分和白菜产量的顺序为腐植酸>沸石>蛭石,其优化组合为每公顷施用腐植酸450kg、沸石225kg、蛭石450kg,该组合能有效地降低设施园艺土壤盐分和提高白菜生物量。
The effects of humic acid, zeolite and vermiculite on soil salinity and cabbage growth were studied using 3-factor 3-level orthogonal design. The results showed that humus> zeolite> vermiculite affected soil salinity and cabbage yield in the order of 450 kg humic acid per hectare, 225 kg zeolite and 450 kg vermiculite. This combination can effectively reduce soil salinity and Improve cabbage biomass.
