长江流域早春大棚栽培的黄瓜和瓠瓜，“化瓜”现象十分严重。应用生长调节剂能有效地防止“化瓜”。研究结果表明，不同组合的生长素类调节剂及ＢＲ与ＣＰＰＵ处理，能明显提高座果率，平均增产达２８．３％，对黄瓜和瓠瓜开花后一天的雌花，用５ｍｇ／ｋｇＣＰＰＵ、０．０１ｍｇ／ｋｇＢＲ、１０ｍｇ／ｋｇＣＰＰＵ及１００ｍｇ／ｋｇＰＣＰＡ＋２５ｍｇ／ｋｇＧＡ对黄瓜增产显著，而５０ｍｇ／ｋｇＮＡＡ＋２５ｍｇ／ｋｇＧＡ与１００ｍｇ／ｋｇＰＣＰＡ＋２５ｍｇ／ｋｇＧＡ对瓠瓜增产明显。对革果重和果实干物质含量的影响，黄瓜和瓠瓜各处理间有不同变化，但变幅不大。
Cucumber and cucumber melon cultivated in the greenhouse in the early spring in the Yangtze River valley, “melon” phenomenon is very serious. Application of growth regulators can effectively prevent “melon”. The results showed that different combinations of auxin regulators and BR and CPPU treatment, can significantly improve the rate of fruit set, the average yield of up to 28.3%, on the day after flowering cucumber and melon flower female, with 5mg / kgCPPU, 0 The results showed that the yield of cucumber increased significantly with the addition of 50mg / kg NAA + 25mg / kg GA and 100mg / kg PCA + 25mg / kg GA at the concentrations of 0.01mg / kgBR, 10mg / kgCPPU and 100mg / kgPCPA + 25mg / kgGA. On the fruit weight and fruit dry matter content, cucumber and cucumber melon treatment between the different changes, but not change.
