摘　　要：为了研究"宇花灵2号"对薄皮甜瓜植株生长及果实品质性状的影响,本文以"甬甜8号"和"甬甜22"薄皮甜瓜为试验对象,分别于6叶期、伸蔓期、雌花抽生期、果实膨大期喷施"宇花灵2号",并考察植株性状和果实品质。结果显示,叶长、叶宽、单果重、单株结果数、小区产量在不同处理间差异达显著水平以上。"甬甜8号"的叶长和叶宽较CK小2.17cm和2.92cm,而单果重、单株结果数、小区产量分别较CK高18.15g、0.27个、8.1kg,较CK增产6.59%;"甬甜22"的叶长和叶宽较CK小1.07cm和1.44cm,而单果重、单株结果数、小区产量分别较CK高42.91g、0.54个和20.36kg,较CK增产14.57%。可见,喷施"宇花灵2号"具有使叶片变小、改善田间通风透光、增加结果数、提高单果重和产量的作用,适用于薄皮甜瓜的简约化栽培。In order to study the effect of"Yuhualing No.2"on the plant growth and fruit quality characteristics of thin skinned melon,the experiment was conducted with"Yongtian No.8"and"Yongtian No.22"muskmelon."Yuhualing 2"was sprayed at 6 leaf stage,extending vine stage,female flower extraction stage and fruit expansion stage,and the plant traits and fruit quality were investigated.The results showed that leaf length,leaf width,single fruit weight,plant number per plant and plot yield varied significantly among different treatments.The leaf length and leaf width of"Yongtian No.8"was smaller than that of CK(2.17cm and 2.92cm),and the single fruit weight,fruit number per plant and plot yield were higher than that of CK(18.15g,0.27,8.1kg),the plot yield of CK was increased by 6.59%.The leaf length and leaf width of"Yongtian No.22"was smaller than that of CK(1.07cm and 1.44cm),and single fruit weight,fruit number per plant and plot yield were higher than that of CK(42.91g,0.54,20.36kg),the plot yield of CK was increased by 14.57%.The results showed that spraying"Yuhualing No.2"has the function of making the leaves smaller,improving the ventilation and light transmittance in the field,increasing the number of fruits per plant,increasing the weight of single fruit and yield.It is suitable for simplified cultivation of oriental melon.
