摘要： 在DFT栽培条件下，从定植到收获，甜瓜日平均吸收营养液0.41L,定果后10天内出现吸收峰值（1.13L/株）,收获前仍维持较高水平。不同生长时期内，甜瓜对钾、钙、镁、磷的吸收变化与甜瓜对营养液的吸收变化基本相似，营养生长时期，吸收量较少，授粉后吸收量急剧增加，在定果后10天内出现吸收峰值，此后急剧减少，但甜瓜对钾的吸收峰值超前一周出现。根据甜瓜对主要大量元素的实际吸收浓度，可以推算甜瓜合适的营养液配方。

Abstract: Nutrient solution uptake by muskmelon was 0 41 litre daily per plant from planting to harvest in DFT.Uptake of nutrient solution wasn't reduced remarkably until harvest.The uptake of K,Ca,Mg,P and the solution varied similarly in different growth periods.The capacity of uptake was found higher after pollination,the highest within 10 days after the final fruit thinning,and reduced rapidly afterwards.However,the highest value of K uptake appeared a week in advance of other.According to the optional concentrations for macro elements uptake by muskmelon,the appropriate solution formula was proposed.

Key words: Muskmelon, Nutrient Solution, Macro elements uptake
