施用沼肥对生菜生长特性及品质影响的研究

通过沼肥与化肥的混合施用,试验研究了沼肥对生菜生长特性及其品质的影响,目的是为沼气的综合利用提供理论依据和技术支持.试验结果表明：施用沼肥能有效提高生菜产量,改善生菜的植物学性状和营养品质,特别是在喷施沼液的情况下,当沼渣与化肥配比为8：2时,生菜产量最高,品质最优.

Effects of anaerobic fermentation residues on growth characteristics and nutrition quality of lettuce

The paper is to study the effects of anaerobic fermentation residues- chemical fertilizer application on the growth characteristics and quality of lettuce,the target is to provide new way to the comprehensive utilization of biogas. The test results show that anaerobic fermentation residue could not only increase the production of lettuce effectively, but also improve the botany character and the nutrition quality of lettuce, especially in the case of spraying biogas slurry; when the proportion of anaerobic fermentation residues and chemical fertilizer is 8:2, the production is the highest, and the nutrition quality is the best.
