摘要
以金蒜3号为试材，研究叶面喷施不同浓度亚硒酸钠和硫酸钠对大蒜光合特性、产量及品质的影响。结果表明，喷施硫浓度200 mg/L、硒浓度20-30 mg/L的溶液，能显著提高大蒜叶片中光合色素的含量、提高光合参数值、改善光合性能；同时，对大蒜鳞茎和蒜薹积累营养物质、提高品质的效果最佳。喷施硫浓度100 mg/L、硒浓度20 mg/L的溶液，大蒜鳞茎和蒜薹的产量及外观品质达到最大值，单蒜头鲜质量、蒜头横径、单蒜薹鲜质量及蒜薹长度比对照分别提高37．3％、30．3％、47．0％和45．7％。
Using garlic variety Jinsuan 3 as material,the effects of foliar spraying different concentrations of sodium selenite and sodium sulfate on the photosynthetic characteristics,yield and quality of garlic （Allium sativum L.）were studied.The results indicated that spraying 200 mg/L sodium sulfate and 20-30 mg/L so-dium selenite could significantly increase the content of photosynthetic pigment,improve photosynthetic param-eter and photosynthetic property in garlic leaves.And it had the optimum effects on nutrient accumulation and quality improving of bulbs and bolts.Spraying 100 mg/L sodium sulfate and 20 mg/L sodium selenite,the yield and exterior qualities of bulbs and bolts reached the maximum.The fresh weight and transverse diameter of bulb,the fresh weight and length of bolt increased by 37.3%,30.3%,47.0% and 45.7% respectively than those of control.
