摘　　要：针对国内温室西葫芦生产过程中存在的盲目施用肥料而造成的瓜菜产量和品质的降低问题进行了研究。以河北培根生物科技有限公司生产的微生物肥料(添加聚天冬氨酸)为供试肥料,以N、P_(2)O_(5)、K_(2)O不同养分比例设置试验处理(T1、T2、T3)、普通复合肥料(N 15%、P_(2)O_(5) 15%、K_(2)O 15%)作为CK处理进行了相关试验,通过对西葫芦不同生物阶段的多个指标进行综合分析,结果发现,在试验范围内T1(N 16%、P_(2)O_(5) 9%、K_(2)O 20%)处理效果最佳;所试验的肥料促进西葫芦的营养生长、促进开花坐果、加快果实发育速度,还能提高瓜菜外观品质、可溶性糖含量和V_C含量,显著提高了产量和经济效益。To study the reduction in yield and quality of Cucurbita pepo L.caused by blind application of fertilizers during the production in domestic greenhouses,in this study,the compound microbial fertilizer containing polyaspartic acid(PASP)produced by Hebei Peigen Biotechnology Co.,Ltd.was used as the test fertilizer,and the related experiments were conducted with different nutrient ratios of N,P_(2)O_(5),K_(2)O set for experimental treatment(T1,T2,T3),and common compound fertilizer(N 15%,P_(2)O_(5)15%,K_(2)O 15%)as CK treatment.Through comprehensive analysis of multiple indicators at different biological stages of Cucurbita pepo L.,it was found that T1 treatment(N 16%,P_(2)O_(5)9%,K_(2)O 20%)had the best effect within the experimental range;The fertilizer tested not only promotes the nutritional growth of Cucurbita pepo L.,promotes flowering and fruit setting,but also improves the appearance quality,soluble sugar content,and VC content,significantly improving yield and economic benefits.
