摘　　要：以西洋南瓜新品种“锦华”为试材，研究了不同整枝方式、种植密度、基肥用量和追肥类型等对其产量的影响。结果表明：西洋南瓜以单蔓整枝为佳；立架栽培适宜的种植密度为1000-1200株／667m2；667n12基肥施肥量以有机肥300k＋复合肥80k为宜；春播露地以单蔓整枝的方式，利用主蔓结果，密度应控制在600株／667m2，以667m2施50kg复合肥作基肥较为合适，膨瓜期再适施10kg的尿素，可有效提高南瓜的产量。Taking new variety ＇Jinhua＇ of Cucurbita maxima Duch. as test material,effect of different pruning types, planting density,base fertilizer application quantity and top dressing type on its yield were studied. The results showed that the optimum pruning type of Cucurbita maxima Duch. was single vine pruning and the optimum planting density of trellis-cultivation was 1 000--1 200 plant per 667 m2 , the amount of base fertilizer application was 300 kg organic fertilizer with 80 kg synthetic fertilizer per 667 m2. In order to improve the yield during spring production, the planting density during 600 plant/667m2, using 50 kg/667m2 synthetic fertilizer as base fertilizer and 667 m2 apply 10 kg urea at fruit expansion period was better.
