丛枝菌根真菌(AMF)对盐碱地韭菜产量及品质的影响

Effects of Arbuscular Mycorrhizal Fungi (AMF) on the Yield and Quality of Chinese Chives in Saline-alkali Soil

  • 摘要: 以抗病、抗逆性强的韭菜品种“独根红”和“平丰10号”为试材,采用随机区组试验法,研究了中度滨海盐碱地(含盐量约0.25%,pH 8.0)大田减肥条件下施用丛枝菌根真菌(AMF)对韭菜主要农艺性状、产量和品质的影响,以期为韭菜在盐碱条件下的绿色高效生产提供参考依据。结果表明:施用AMF对盐碱地韭菜幼苗生长发育无显著影响;添加AMF和钙肥,适当减少肥料的施用不影响盐碱地韭菜正常生长;适当添加钙肥和AMF可在减肥条件下不降低其它品质指标的同时提高韭菜维生素C含量;该试验条件下,“独根红”韭菜在处理T6(667 m2施用硫酸钾复合肥30 kg、硝酸铵钙10 kg,添加AMF)条件下产量最高,比常规施肥方式(667 m2施用硫酸钾复合肥50 kg)高21.38%。

     

    Abstract: Two Chinese chives cultivars, ‘Dugenhong’ and ‘Pingfeng10’,with strong resistance against disease and biotic stresses, were selected as the materials.The effects of arbuscular mycorrhizal fungi(AMF) on main agronomic characteristics, yield, and quality of Chinese chives on moderate coastal saline-alkali land(salt content was about 0.25%,pH 8.0) were evaluated with a randomized block design, in order to provide novel insights into for highly efficient and green production of Chinese chives under saline-alkali conditions.The results showed that the application of AMF had no significant effect on the growth and development of Chinese chives seedlings on saline-alkali soil.Adding AMF and calcium fertilizer would not affect the normal growth of Chinese chives on saline-alkali soil under the condition of appropriate reduced fertilizer application.Appropriate application of calcium fertilizer and AMF could increase the ascorbic acid(vitamin C) content in Chinese chives without reducing other quality traits and had no adverse effect on the stress resistance on saline-alkali soil.The yield of ‘Dugenhong’ with T6 treatment(potassium sulfate compound fertilizer 30 kg per 667 m~2,ammonium nitrate-calcium nitrate 10 kg per 667 m~2,AMF) was the highest, which was 21.38% higher than that of T1 treatment(potassium sulfate compound fertilizer 50 kg per 667 m~2).
