甜瓜属延伸根系,能有效地聂取土壤中的水份和养分,因此,与许多其他蔬菜作物相比,甜瓜的需肥量是中等。通常需要的肥料是氮,但是为了获得高产优质甜瓜,有时也需要磷。一般说来,在结构中等或良好的土壤上,每英亩施氮100—150磅(每公顷112—168公斤)便能为甜瓜提供足够的氮。荒地种甜瓜需要多量的磷。秋种甜瓜通常每英亩吸收100磅P_2O_5,(每公顷112公斤),春种甜瓜每英亩吸收200磅P_2O_5(每公顷224公斤)。磷酸或10—34—0液肥(聚磷酸铵,其中N—10、P—34、K—0)是春种甜瓜最常见的磷源。液肥通常施
Melon is an extended root system that efficiently removes water and nutrients from the soil, so the amount of fertilizer required for melon is moderate compared to many other vegetable crops. The fertilizer that is usually needed is nitrogen, but phosphorus is also sometimes needed in order to obtain high yield, good quality melons. In general, 100-150 pounds of nitrogen per acre (112-168 kilograms per hectare) provide sufficient nitrogen for muskmelon on medium or good soils. Badlands melons need a lot of phosphorus. Autumn melons usually absorb 100 pounds of P 2 O 5 per acre, (112 kilograms per hectare) and spring melons absorb 200 pounds of P 2 O 5 per acre (224 kilograms per hectare). Phosphoric acid or 10-34-0 liquid fertilizer (ammonium polyphosphate, N-10, P-34, K-0) is the most common phosphorus source for spring melons. Liquid fertilizer is usually applied
