本文研究了在温室基质栽培和不施加任何化学肥料的情况下,接种内生真菌印度梨形孢8周后对芹菜生长及营养品质,尤其是矿物元素含量的影响。结果表明,印度梨形孢和芹菜的共生能显著促进芹菜的生长,接种2周和8周后芹菜的茎叶鲜重、根鲜重及植株鲜重分别高于对照50%和70%以上。接种8周后芹菜的产量与对照相比提高了70.7%,植株高度提高了30.2%,分蘖数提高了34.4%。芹菜植株更健壮,色泽更绿。芹菜中的VC含量和可溶性蛋白含量分别高于对照7.9%和15.0%,Ca、Mg、K、Na、Zn和Fe等矿物元素的含量分别比对照高83.8%,50.8%,53.6%,87.7%,37.8%和59.0%,而铜、锰及总黄酮含量和对照没有显著差异。结果表明:印度梨形孢能显著促进芹菜的生长,提高芹菜的营养品质。同时可减少化学肥料的使用,对保障食品安全性具有重要作用。
In this paper, the effects of inoculation with endophytic fungus, Rhizoctonia solani, on the growth and nutritional quality of celery, especially the content of mineral elements, were studied in the greenhouse with or without chemical fertilizers. The results showed that the symbiosis of Indian pear spore and celery could significantly promote the growth of celery. After 2 weeks and 8 weeks of inoculation, the fresh weight of stem, fresh weight and fresh weight of celery were higher than that of the control by 50% and 70% respectively. After 8 weeks of inoculation, the yield of celery rose by 70.7% compared with the control, the plant height increased by 30.2% and the tiller number increased by 34.4%. Celery plant more robust, more greener. The contents of VC and soluble protein in celery were 7.9% and 15.0% higher than those in the control respectively. The content of mineral elements such as Ca, Mg, K, Na, Zn and Fe were 83.8%, 50.8%, 53.6% and 87.7% , 37.8% and 59.0%, respectively, while the contents of Cu, Mn and total flavonoids were not significantly different from the control. The results showed that P. pearls could significantly promote the growth of celery and improve the nutritional quality of celery. At the same time can reduce the use of chemical fertilizers, to ensure food safety has an important role.
