摘要: 为探讨化肥减施对日光温室芹菜生长及土壤性质的影响,在施用有机肥的基础上,采用传统施肥方式,设100%施化肥、减施10%化肥、减施25%化肥、减施35%化肥4种处理,研究了日光温室芹菜生长、生理和土壤养分等指标的变化。结果表明:在施用有机肥情况下,与传统施肥方式相比,化肥减施35%对土壤全量养分影响不大,全氮、全磷、全钾和有机质含量在不同处理间差异均不显著;芹菜收获后不同施肥处理土壤硝态氮、有效磷仍处于较高水平,化肥减施25%和减施35%处理土壤速效钾含量显著低于化肥100%处理;化肥减施对土壤容重和pH影响不大,但高量化肥可显著增加土壤EC值;在芹菜株高、叶片氮素和叶绿素含量及产量方面,100%化肥施用与化肥减量施用各处理之间差异不显著。

Abstract: In order to investigate the effects of chemical fertilizer reduction on the growth and soil properties of celery in greenhouse, the application of 100% chemical fertilizer, 10% chemical fertilizer reduction, 25% chemical fertilizer reduction and 35% chemical fertilizer reduction treatments were studied on the basis of organic fertilizer application. Changes in growth physiology and soil nutrients of celery in daylight greenhouses were studied. The test results showed that, in the case of applying organic fertilizer, compared with traditional fertilization, the reduction of chemical fertilizer to 35% had little effect on the total nutrient of the soil, and the difference between the treatments of total nitrogen, total phosphorus, total potassium and organic matter was not significant; soil nitrate nitrogen and available phosphorus were still at a high level after different fertilization treatments; in the fertilizer reduction of 25% and 35% treatments soil available potassium was significantly lower than that of 100% chemical fertilizer treatment; the effect of fertilizer reduction on soil bulk density and pH was not significant; large and high-quantity fertilizer significantly increased soil EC values; celery plant height, leaf nitrogen, chlorophyll content and yield between 100% chemical fertilizer application and chemical fertilizer reduction application were not significantly different.
