摘　　要：以甜瓜品种"金妃"为试材,采用叶面喷施方式,设置不同钼营养浓度水平分别为0、0.1%、0.2%、0.4%、0.8%,通过测定甜瓜果实横径、纵径、叶绿素含量、硝态氮含量、硝酸还原酶活性和单瓜质量等指标,研究钼营养对甜瓜产量形成的作用效应。结果表明:在浓度为0.4%钼营养处理水平时,能有效地提高叶绿素含量,改善硝酸还原酶活性,减少硝态氮累积,也促进了植物对硝态氮的转化和利用,增大果实横径、纵径及单瓜质量,从而促进产量的形成。Muskmelon cultivar‘Jinfei＇was used as test material,different concentration of molybdenum levels（0,0.1%,0.2%,0.4%,0.8%）were set by spraying on the leaf.The effect of different concentration of molybdenum on muskmelon fruit transverse diameter,vertical length,chlorophyll content,nitrate nitrogen,nitrate reductase activity and single fruit weight index was determined,the effect of molybdenum nutrition on muskmelon yield formation was studied.The results showed that,the concentration of 0.4% molybdenum processing level could effectively increase the chlorophyll content,nitrate reductase activity,reduce nitrate accumulation,but also could promote the transformation and use of nitrate nitrogen,increase the fruit transverse and longitudinal diameter and single fruit weight so as to promote the formation of the production.
