沼液追肥对菇渣复合基质栽培生菜产量和品质的影响
Effect of biogas slurry on the yield and quality of lettuce in compound substrate with mushroom compost dregs cultivation
摘要
Abstract
To study the two agricultural secondary wastes of biogas slurry and mushroom compost dregs in application technique for vegetable crops soilless cultivation, the effect of biogas slurry of different concentrations and different methods on the yield and quality of lettuce was studied through experiments of biogas slurry as supply application with water at different ratios. In the experiment, the mixture of mushroom compost dregs and turf was used as substrate of lettuce culture with the ratio of 1: 1. The result showed that the biogas slurry of appropriate concentration could increase the yield of lettuce, and improve the quality of lettuce. The optimal combination of biogas slurry at the volumetric ratio of biogas slurry and water was 1:4 for spraying on leaves of lettuce. The highest yield of lettuce was 6 607.39 kg · hm-3 when this treatment was used and the rhizosphere had lower specific conductivity. The higher content of Vc of lettuce was 2 186. 2 mg · kg-1, which was used and it was 20% higher than that of the control. The content of nitrate of lettuce was 510. 56μg · g-1, which was significantly lower than that the nitrate content standard of 3 000 mg · kg -1.关键词
