【摘要】 【目的】研究球毛壳菌生物菌肥不同用量对草莓植株生长、果实产量和品质的影响,为球毛壳菌生物菌肥在生产上的应用提供参考。【方法】在温室大棚中开展试验,按不同球毛壳菌生物菌肥施肥量(0.5、1.0、2.0g/株)设3个处理,不施肥为对照处理,检测内生真菌球毛壳菌ND35在草莓上的定殖率;分析不同菌肥用量对草莓生物量和生理指标及果实产量和品质的影响。【结果】球毛壳菌ND35可以在草莓植株内定殖,其定殖率与菌肥用量正相关。不同处理的球毛壳菌生物菌肥对草莓植株生长、果实产量和品质具有显著影响,施用0.5g/株和1.0g/株的菌肥用量有利于草莓的生长和发育。【结论】0.5~1.0g/株用量的球毛壳菌生物菌肥可提高草莓产量和改善其品质,球毛壳菌生物菌肥可应用于草莓田间大规模生产中。更多还原

【Abstract】 [Objective]The present study was conducted to investigate effect of different dosages of fungal biofertilizer from Chaetomium globosum on growth,yield and quality of strawberry to provide references for utilizing the fungal biofertilizer in the field in future. [Method]Zhangji strawberry and fungal biofertilizer from C. globosum were served as test materials. Percentage of colonization of endophytic fungus C. globosum ND35 was detected in strawberry. Effects of fungal biofertilizer with different dosages of C. globosum spores on biomassy,physiological quota of strawberry and production and quality of fruits were investigated and analyzed in the field and in laboratory. [Result]Endophytic fungus C. globosum ND35 was able to colonize within plant of strawberry. Colonization rate was positively related to spores dosages of fungal biofertilizer. Different treatment of fungal biofertilizer from C. globosum significantly influenced growth,yield and quality of strawberry. Applying fungal biofertilizer at 0.5 g/plant and 1.0 g/plant was able to promote growth and development of strawberry. [Conclusion]The 0.5-1.0 g/plant utilizing dosages of fungal biofertilizer from C. globosum was able to increase yield and improve quality of strawberry.更多还原
