配方施肥对温室迷你黄瓜生长·产量及品质的影响

Effect of Formula Fertilization on Growth,Yield and Quality of Mini-cucumber in Greenhouse

为了探明配方施肥对基质栽培迷你黄瓜生长发育的影响,优化温室迷你黄瓜生产的施肥方式。以“津美3号”迷你黄瓜为试材,设置5种不同施肥方式,探究配方施肥对温室迷你黄瓜的生长、产量及品质的影响。结果表明,以有机肥中磷含量为基准,不足部分用无机肥来补充的T3处理和以有机肥中钾含量为基准,不足部分用无机肥来补充的T4处理的生长状况显著优于其他处理,T3和T4处理的产量和经济效益与采用无机肥的配方施肥的T5处理无显著差异,但均显著高于常规Hoagland营养液浇灌的T1处理与单施有机肥的T2处理,T3、T4处理的迷你黄瓜品质显著优于T5处理。综合生长、产量、品质和经济效益指标,有机肥与无机肥配施的T3与T4处理综合表现最优。

To elucidate the effect of formula fertilization on the growth,yield and economic benefits of substrate-planted mini-cucumber,and optimize the fertilization method of greenhouse mini-cucumber production.Cultivar of“Jinmei 3”mini-cucumber was used for greenhouse test.Five different fertilization methods were set in this experiment.The cucumber plants treated with different fertilization treatments were grown under the same growth conditions.The growth parameter,yield and fruit quality of mini-cucumber were measured.The results showed that the T3 treatment which was phosphorus content of organic fertilizer as the benchmark,insufficient part supplemented with inorganic fertilizer and the T4 treatment of organic fertilizer potassium content as the benchmark,insufficient part supplemented with inorganic fertilizer were significantly better than other treatments in growth.The yield and economic benefit of T3 and T4 treatments were not significantly different from T5 treatment which was used inorganic fertilizer formula fertilization,and were significantly better than the T1 treatment which was fertilized by Hoagland nutrient solution and the T2 treatment which was used single application of organic fertilization.The quality of T3 and T4 treated mini-cucumber was significantly better than T5 treatment.Combining comprehensively the indexes of growth,yield,quality and economic benifit,the T3 and T4 treatments of organic and chemical fertilizer application performed the best in all treatments.
