Melon cv. Bonasu was cultivated by 12 Sandponics bed (W60cm L10m D7cm) systems. Each bed was irrigated by microtube type drip hose and was covered by the three kinds of mulching materials; black, white and silver color polyethylene film showed the best effects. The growth of melon plants improved with black film, and the sugar content of black film showed the highest value of 14.7%. Snadponics was able to save irrigation water ca.80% compared with a common cultivated method.Transpiration, photosynthesis water use efficiency, Leaf conductance and intercellular <CO_2> concentration were measured under several kinds of meteorogical conditions.i.e., air temperature, relative humidity (RH) and light intensity.

甜瓜cv.盆栽采用12个沙培(W60 cm、L10m、D7 cm)系统。每张床均用微管式滴灌软管浇灌，并用三种覆盖材料覆盖，以黑色、白色和银色聚乙烯薄膜效果最好。黑膜对甜瓜植株生长有促进作用，黑膜含糖量最高，达14.7%。试验测定了不同气象条件下的蒸腾作用、光合作用水分利用效率、叶片电导和胞间浓度，即气温、相对湿度和光照强度。
