Abstract:
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 667m2,the amount of base fertilizer application was 300 kg organic fertilizer with 80 kg synthetic fertilizer per 667m2.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 66 m2 apply 10 kg urea at fruit expansion period was better.
