摘　　要：于西瓜伸蔓期、开花坐果期、果实膨大期,叶面喷施"宇花灵",植株生长稳健,叶色浓绿,叶片厚,光泽增强,有效提高叶片光合效益。宇花灵1号于伸蔓期叶面喷施,可促进植株藤蔓生长,于果实膨大期使用可补充植株营养,减缓植株衰老速度;开花坐果期喷施宇花灵3号,可调节植株营养生长及生殖生长关系,促进开花坐果。结果表明,处理植株单株瓜数提高25.4%、单瓜重提高12.22%、产量提高40.72%。同时对植株叶片营养含量及抗性进行初步探讨。In watermelon growing period（vine-extending stage,flowering and fruit setting stage,fruit expanding stage） ,spray on the leaf blade with bio-type organic nutrition agent Yu Hua Ling,promote plant growth stronger,make leaves dark green with thick shape,enhance the ability of leaves,photosynthesis.In the vine-extending stage and fruit expanding stage,spray on the leaf blade with yuhualing no.1,can promote bind growth and supplementary nutrient and postpone agine.In flowering and fruit setting stage,spray on the leaf blade with yuhualing no.3,can regulating vegetative and reproductive growth,increase output of fruit.The result show that,can bring a growth of 25.4% for fruit-beaing number per plant,and 12.22% for per fruit weight and 40.72% for yield.And preliminarily studied at the nutrition content of leaf and resistance.
