不同苗龄、株距和基追肥比例对春早熟南瓜产量和品质的影响
Effects of Different Seedling Ages,Plant Spacings and Base-topdressing Fertilizer Ratios on the Yield and Quality of Early-maturing Pumpkin in Spring
摘要
Abstract
To investigate the effects of cultivation factors on the yield and quality of pumpkin(Cucurbita spp.)and to optimize the cultivation technologies for early-maturing pumpkin in spring,a study was conducted using the'Cuili No.6'variety under spring plastic-greenhouse conditions in the Shaoxing area.The experiment systematically examined the effects of three single factors on seedling traits,yield and fruit quality,including seedling age[3 leaves and 1 heart,2 leaves and 1 heart(CK1)],plant spacing[55,50,45 cm(CK2)]and base-topdressing fertilizer ratio[3∶7,5∶5,7∶3,10∶0(CK3)].The results showed that the 3-leaf-1-heart seedling age treatment produced superior quality seedlings,with the whole-plant fresh weight and dry weight significantly increased by 12.9％and extremely significantly increased by 55.2％compared to CK1,respectiveliy,and the strong seedling index was significantly improved by 47.7％.The highest yield per unit area was achieved with a plant spacing of 50 cm,but the soluble solids content was significantly lower than that of CK2.With a base-topdressing fertilizer ratio of 3∶7,the yield per 667 m2 reached the highest,significantly increasing by 22.2％and 4.2％compared to the 5∶5 and 7∶3 treatments,respectively,while showing no significant difference from CK3.Additionally,the soluble solids content under the fertilizer ratio of 3∶7 was significantly increased by 10.3％and 7.5％compared to the 7∶3 treatment and CK3,respectively.In conclusion,the cultivation combination of 3-leaf-l-heart seedling age,50 cm plant spacing and 3∶7 base-topdressing fertilizer ratio can achieve the goal of high yield and quality in pumpkin production.It is recommended to implement this approach flexibly based on specific production objectives.关键词
