[目的]明确西瓜生长的最适营养基质施用量,以期获得最佳的经济效益。[方法]采用基质栽培方法,对西瓜品种8424施用不同量的营养基质,明确西瓜生长的最适营养基质施用量。[结果]研究结果表明,西瓜营养基质的施用量在60～75 m3/hm2时,西瓜叶片数、主蔓长、单果重、产量以及中心糖分、边糖分含量等产量、品质指标均处于最佳状态。[结论]综合考虑多方面因素,西瓜营养基质的用量为60～75 m3/hm2。
[Objective] To determine the optimal nutrient substrate for watermelon growth in order to obtain the best economic benefits. [Method] With substrate culture method, different amount of nutrient matrix was applied to watermelon variety 8424, and the optimum nutrient substrate for watermelon growth was determined. [Result] The results showed that when the watermelon nutrient substrate was applied at 60 ~ 75 m3 / hm2, yield, quality indicators such as watermelon leaf number, main vine length, single fruit weight, yield, center sugar, status. [Conclusion] Considering many factors, the amount of watermelon nutrient matrix was 60 ~ 75 m3 / hm2.
