摘要
为更好地指导瓜农进行大棚多膜覆盖西瓜生产,探讨了西瓜多膜覆盖形成的小气候因素西瓜产量、品质及效益的影响。结果表明：5膜大棚平均温度比4膜大棚高1.37℃,平均最低温度比4膜大棚高1.67℃;5膜大棚平均相对湿度在10：00—13：00期间略低于4膜大棚,其余时间均高于4膜大棚;5膜大棚西瓜比4膜大棚的上市早15~20 d,每667 m2多收1 295.6元;5膜大棚西瓜比4大棚膜西瓜含糖量略低,总体品质相近。
The effects of microclimate factors of greenhouse more film on yield, quality and benefits of watermelon were studied and analyzed. The results showed that the daily average temperature and the average low temperature in greenhouse with five film was 1.24 ℃ and 1.67 ℃ higher than that of four film respectively, the average relative humidity of five film greenhouse was slightly lower than the four film one during 10.am to 1.pm, while the relative humidity of five film green- house was higher than the four film one on the other time. Watermelon was early maturity 15-20 d in five film greenhouse than the four film. The income of five film greenhouse was more 1 295.6 yuan than the four film one, the sugar content of five membrane watermelon was slightly lower than the four film ones and the quality of watermelons of five film were similar to the four film ones.
