【摘要】 本研究以津优3号为试验材料,研究了饼肥施用量对黄瓜生长、产量及果实品质的影响。结果表明:饼肥用量低于200kg／667m2时,黄瓜株高与CK差异不大,叶面积较显著增加,但饼肥用量达到300kg／667m2时,植株略有徒长,叶面积有所减小。在0～200kg／ 667m2范围内,随着饼肥用量的增加,黄瓜产量逐渐增加,但施肥量超过了200kg／667m2时, 呈下降趋势。各处理商品成熟黄瓜果实在适量施用饼肥时,果实中可溶性糖、蛋白质和Vc的含量都显著增加,但施肥量超过了200kg／667m2时,以下指标均有下降趋势。饼肥的施用量越多,硝酸盐的含量越低。综合评定饼肥用量对黄瓜产量的品质的影响认为,在本试验土壤肥力水平下,以每666．7m2施100～200kg饼肥较宜,可供同类肥力水平土壤生产中参考应用。更多还原

【Abstract】 Effect of cake fertilizer on growth, yield and quality of cucumber withwere studied. The result showed that there was little effect of cake fertilizer on plant height within the confine of 0-200 kg/667m2, but when 300 kg/667m2 cake fertilizer was applied, the plants height increased a little. In the range of 0-200kg/667m2, the leaf area and yield increased as cake fertilizer increased. While more than 200kg/667m2were used, the leaf area and yield decrease gradually. Proper cake fertilizer were used, the soluble suger, protein and Vc content of cucumber friut all increased obviously. But if cake fertilizer application were more than 200kg/667m2, the above indexes descended. The more cake fertilizer were applied, the less the nitrat conten. Comprehensive assess the effect of cake fertilizer on yield and quality of cucumber, we considered that 100-200kg/666. 7m2 cake fertilizer was required for maximum yield and better quality at the same nutrition fild as the experimental condition.更多还原
