The invention discloses a soilless culture method for high-
sugar Hami melons, which comprises the steps of
sowing and
seedling raising, planting, preparing
nutrient solution, controlling temperature,
pruning and leaving fruit, and the like, wherein the
nutrient solution contains 20-50mg / kg
gibberellin, 20-50g / kg
sodium borate, 3-15g / kg
monopotassium phosphate, 10-15mg / kg 6-benzyladenine, 30-50mg / kg brassin and 20-50mg / kg
diethyl aminoethyl hexanoate; at different stages, the
temperature control is as follows: the temperature is controlled at 18-22 DEG C at night and 25-30 DEG C in the
daytime during the period from planting to surviving; the temperature is controlled at 15-20 DEG C at night and 28-35 DEG C in the
daytime during the period from surviving to blooming; during a melon growing period, the temperature is controlled at 22-27 DEG C in the
daytime and 15-18 DEG C at night, and an
ultraviolet lamp is used for illuminating for 1-2 hours with the luminance being 1500-2000muW / cm<2>; and after the melon growing, the shed temperature is kept at 30-35 DEG C in the daytime and 15-18 DEG C at night, and the
ultraviolet lamp is used for illuminating for 2-3 hours, with the luminance being 5-10mW / cm<2>. According to the method provided by the invention, the quality such as the
sweetness of the Hami melons is increased, and meanwhile, the fruit
cracking phenomenon is reduced.
