摘要
针对设施瓜果类蔬菜生产中化肥施用过量的问题,在武汉市设施瓜果类蔬菜主产区,通过田间小区试验研究了3种化肥减施技术对黄瓜产量和品质的影响。化肥减施技术包括测土配方施肥(T2)、有机肥替代(T3)、有机小分子水溶肥料水肥一体化(T4)。研究表明,与农民习惯施肥处理(T1)相比,T2处理每667 m^(2)增产11.14%,T3处理每667 m^(2)增产8.95%,T4处理每667 m^(2)减产0.41%。各减肥技术都显著提高了黄瓜的可溶性糖、蛋白质、VC含量,降低了黄瓜的硝酸盐含量,T3、T4处理黄瓜的营养品质最好。在黄瓜氮、磷、钾养分累计吸收量方面,T3处理最高。在本试验条件下,有机肥替代30%的化肥技术效果最优。
In response to the problem of excessive chemical fertilizer application in the production of facility melon and fruit vegetables,the effects of three chemical fertilizer reduction techniques on cucumber yield and quality were investigated by field plot trials in the main production areas of facility melon and fruit vegetables in Wuhan.The chemical fertilizer reduction techniques included soil testing and formula fertilization(T2),organic fertilizer substitution(T3),and organic small molecule water soluble fertilizer water integration(T4).The study showed that compared with farmers’customary fertilizer application treatment(T1),the T2 treatment increased yield by 11.14%per 667 m^(2),T3 treatment increased yield by 8.95%per 667 m^(2),and T4 treatment reduced yield by 0.41%per 667 m^(2).All fertilizer reduction techniques significantly increased the soluble sugar,protein and VC content and reduced the nitrate content of cucumber,with the best nutritional quality of cucumber in T3 and T4 treatments.In terms of cumulative nutrient uptake of nitrogen,phosphorus and potassium in cucumber,T3 treatment was the highest.Under the conditions of this experiment,organic fertilizer substituted 30%of chemical fertilizer technology was the most effective.
