摘要: 为明确甜瓜科学施肥技术、实现甜瓜高产优质施肥,采用田间试验方法研究了不同肥料配比对甜瓜产量、SPAD值、维生素C(Vc)、糖分、养分积累量的影响。结果表明:控释尿素配施硫酸钾产量最高,达到102.69 t/hm2;心糖和边糖含量分别为16.97%和9.90%,较对照分别提高35.54%和33.78%,Vc含量为60.86 mg/kg,较对照提高31.44%;氮、磷、钾积累量较对照分别提高26.86%、35.54%、27.76%。硫酸钾复混肥(15-15-15) 600 kg/hm2和控释尿素(44%)300 kg/hm2作基肥,膨瓜期追K2SO4 300 kg/hm2,促进了对氮、磷、钾养分的吸收利用,提高了产量和品质,可作为甜瓜高产优质的施肥方案。

Abstract: To determine the scientific fertilization technology of melon, achieve high yield and good quality, a field experiment was conducted to study the influence of different fertilizer proportions on yield, SPAD, vitamin C (Vc), sugar and nutrient accumulation of melon. The results showed that the yield under the application of controlled release urea with potassium sulfate was the highest, which reached 102.69 t/hm2. Compared with the control group, the content of heart sugar and side sugar was 16.97% and 9.90%, respectively, increased by 35.54% and 33.78%; the content of Vc was 60.86 mg/kg, increased by 31.44%; the accumulation amounts of nitrogen, phosphorus and potassium increased by 26.86%, 35.54% and 27.76%, respectively. The treatment of potassium sulfate compound fertilizer (15-15-15) 600 kg/hm2 and controlled release urea (44%) 300 kg/hm2 used as basic fertilizer, and 300 kg/hm2 potassium sulfate as topdressing at fruit expansion period could promote the absorption and utilization of nitrogen, phosphorus and potassium and improve the yield and quality.
