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).
