摘要: 采用温室盆栽法，研究桑黄菌糠水提液叶面喷施对小青菜生长的影响。结果表明，低浓度的提取液S2叶面喷施促进小青菜的生长，光合作用增强，小青菜品质提高，产量比清水对照提高7.8%; 高浓度的水提液S0喷施小青菜，对其生长不利。低浓度的水提液S2与NPK营养液混合喷施效果最好，产量比清水对照提高26.3%，达极显著水平。

Abstract: A pot culture experiment was carried out to study effects of spraying aquatic extraction substance from residue (AESR) of P. baumii on Brassica rapa L. The results showed that the spraying of the AESR with low concentration could promote the growth, increased plant biomass and quality, and enhance photosynthesis of Brassica rapa L. Compared to the controls, the plant biomass increased by 7.8%. But spraying with high concentration decreased the plant growth. When the AESR mixed with leaf fertilizer at low concentration, the effects was the best and increased the plant biomass by 26.3% compared to control.
