摘要
【目的】通过在盐碱地中施入土壤调理剂来研究其对草莓根际土壤的水分、盐分变化特征,土壤物理性状的变化规律及草莓品种果实品质、产量的影响,以期改善土壤环境,提高草莓的果实品质及产量,为生产提供理论依据和实践依据。【方法】通过对比诺普丰酸性磷钾肥与优美柯酸性肥在大棚草莓的施用效果,分析施用两种土壤调理剂与常规施肥的大棚草莓干物质积累、SPAD值、主茎生长量、匍匐茎生长量、果实产量品质及土壤物理性状的变化特征,优选适宜当前盐碱地温室大棚应用的土壤调理剂。【结果】施用诺普丰酸性肥对草莓棚土壤总孔隙度、pH值、盐分的调节作用最佳,优美柯次之,对照表现最差;使用诺普丰酸性肥对草莓的生物学性状调节作用最佳,至果实采收期草莓株高、茎粗、冠幅、SPAD值、地上部干物质重分别达到23.00 cm、14.94 mm、21.57 cm、46.89、18.7g,两种酸性肥表现均好于对照;与对照相比,两种酸性肥均能显著提高单株结果数,且产量均高于对照,处理1、处理2每亩(667 m 2)产量达到701.16 kg、633.94 kg。【结论】生育期施用诺普丰酸性磷钾肥,对草莓的生长调节作用最佳,对其产量有一定的提高;同时诺普丰酸性磷钾肥还能够有效改善土壤环境,对土壤总孔隙度、pH值、总盐有一定的调控作用。
【Objective】By applying soil conditioner in saline-alkali soil,the influence of soil conditioner on the variation characteristics of water and salt in strawberry rhizosphere soil,the variation regularity of soil physical properties and the fruit quality and yield of strawberry varieties was studied in order to improve the soil environment,improve the fruit quality and yield of strawberry,and provide theoretical and practical basis for production.【Methods】By comparing the application effect of Nuopufeng phosphate potassium fertilizer and Youmeike acid fertilizer in greenhouse strawberry,analysis of two kinds of soil conditioner and conventional fertilization of greenhouse strawberry dry matter accumulation,SPAD value,main stem growth,stolon growth,fruit yield and quality and the change characteristics of soil physical properties,preferred suitable for the current saline-alkali soil greenhouse application of soil conditioner.【Results】The results of the experiment showed that the application of Nuopufeng acid fertilizer had the best regulation effect on the total porosity,pH value and salt content of strawberry greenhouse soil,followed by Youmeike,and the control was the worst.The use of Nuopufeng acid fertilizer had the best regulatory effect on the biological traits of strawberry.The plant height,stem diameter,crown width,SPAD value and aboveground dry matter weight of strawberry reached 23.00 cm,14.94 mm,21.57 cm,46.89 and 18.7 g,respectively.Compared with the control,the two acid fertilizers could significantly increase the number of fruits per plant,and the yield was higher than that of the control.The yield of treatment 1 and treatment 2 reached 701.16 kg/667 m 2 and 633.94 kg/667 m 2.【Conclusion】During the growth period,the application of Nuopufeng acid phosphate potassium fertilizer had the best regulation effect on strawberry growth and increased its yield to a certain extent.At the same time,Nuopufeng acid under phosphorus can effectively improve soil environment,total soil porosity,pH,total
