摘要
将处理后的树脂脱附液配置成含腐殖酸液体肥料,开展中试应用试验。结果表明:液体肥料作为基肥时,能显著提高青菜的生物量和株高;腐殖酸能有效促进青菜的光合作用;腐殖酸有助于青菜对养分氮素和钾的吸收,不利于植株对磷素的吸收;腐殖酸肥料较常规施肥,对青菜的品质影响不显著。
The treated resin desorption liquid was prepared into humic acid liquid fertilizer to carry out pilot test.The results showed that liquid fertilizer could significantly improve the biomass and plant height of vegetables.Humic acid can effectively promote the photosynthesis of vegetables.Humic acid is beneficial to the absorption of nutrient nitrogen and potassium,but not conducive to the absorption of phosphorus by plant.Compared with conventional fertilization,humic acid fertilizer had no significant effect on the quality of vegetables.
