Abstract

通过温室试验探索了追施腐植酸肥料及生物肥对草莓产量、品质及土壤农化性状的影响。试验在满足草莓正常生长所需肥力的基础上追施腐植酸和生物肥,试验设置4 个处理,分别为:对照(常规施肥处理)、追施腐植酸肥、追施生物肥、追施腐植酸+生物肥,重复3 次,随机排列。研究结果表明:施用生物肥、腐植酸、腐植酸+生物肥能够显著改善草莓长势,盛果期单果重分别提高了8.85%、14.12%和16.23%

显著降低草莓白粉病、灰霉病、烂果病的发生率,进而提高草莓产量,3 个施肥处理产量较对照分别提高了7.70%、10.80%和14.70%

施用腐植酸和生物肥能显著提高草莓蛋白质含量、草莓Vc 含量及可溶性糖的含量,降低草莓游离酸含量,进而提高了糖酸比,改善口感

施用腐植酸和生物肥能显著改善土壤理化性质,提高土壤有机质含量,3 个施肥处理土壤有机质含量分别比对照高0.13、1.51 g·kg-1和1.69 g·kg-1。综上得出,施用腐植酸和生物肥对草莓生长具有积极影响,且2种肥料配合施用效果最佳。

A greenhouse experiment was conducted to study the effect of humic acids and bio-fertilizer on the qualities, yields of strawberry and soil agrochemical characters. Humic acids and bio-fertilizer were applied based on the requirement of the normal growth of strawberry. Four treatments were plotted: control(conventional treatment), dressing humic acid, topdressing bio-fertilizer, dressing humic acid+bio-fer-tilizer. Each treatment was repeated three times and randomly arranged. Results showed that application of bio-fertilization, humic acid, hu-mic acid+bio-fertilization could significantly improve the growing of the strawberry, average weight of strawberry during full burning period increased by 8.85%, 14.12% and 16.23%, respectively

Incidence of powdery mildew, gray mold and rot disease of strawberry was signifi-cantly reduced. Yield of strawberry was also improved by 7.70%, 10.80% and 14.7% respectively, compared with the control treatment. The results also showed that application of humic acid+bio-fertilization could significantly increase the protein, vitamin C and soluble sugar con-tent while reduce free acid of strawberry. Soil organic matter content was significantly improved by 0.13, 1.51 g·kg-1 and 1.69 g·kg-1 respec-tively than control when bio-fertilization, humic acid, humic acid+bio-fertilizer were applied. In summary, humic acid and bio-fertilization had a positive impact on the growth of strawberry. Combined application of those two kinds of fertilizer would show the best agricultural effect.
