不同人工补光光源对早春西瓜嫁接苗生长的影响
Effects of Different Artificial Supplement Light Sources on Grafted Watermelon Seedling Growth in Early Spring
摘要
Abstract
In early spring,under successive cold,rainy and cloudy climate condition,this experiment took 'Nabite' scions grafted onto 'Yongzhen No.5' as material,and exposed them under LED light and high voltage sodium lamp for supplementary light of continuous 25 days,taking natural light as the contrast. The results showed that artificial supplement light could obviously accelerate the growth of grafted watermelon seedlings. After the 17th day under supplementary light,the artificial supplement light treatments had great impact on the growth of seedlings:the hypocotyl lengths of rootstock and scion were rapidly increased,the plant height was remarkably enlarged,leaf areas became bigger,stems became thicker,biomass accumulation was fastened,chlorophyll content was improved,photosynthetic capacity of leaf blades was strengthened,survival rate of grafted seedlings was improved,diseases occurrence rate was reduced. Compared with different light resources,the effect of LED light is better than that of high voltage sodium lamp. Moreover,LED light has lower input and usage cost in long time running. LED light might become one of the most promising artificial supplementary lights in agriculture field in the future.关键词
