功能性材料对次生盐渍化设施土壤理化性质及黄瓜生理特性的影响

Effects of Functional Materials on Secondary Salinization Facilitie Soil Properties and the Physiological Characteristics of Cucumber

为研究功能性肥料对次生盐渍化设施土壤的改良作用,以不同质量比的功能性材料与肥料混合施入设施土壤,以当地常见黄瓜‘德瑞特398’为研究对象,探讨功能性材料对设施黄瓜地土壤理化性质及黄瓜生长生理指标的影响。结果表明,与对照相比,功能性材料的施用能显著提高土壤速效磷含量,且显著增加黄瓜株高、茎粗、叶面积、叶绿素a含量和黄瓜净光合速率。但功能性材料对土壤pH值、可溶盐含量、速效氮和速效钾含量影响较小。由此可得,功能性材料对于提高黄瓜植株的生长发育有明显促进作用,但对次生盐渍化土壤理化性质的影响仍需进一步研究。

In order to study the improvement effect of functional materials on secondary salinization facility soil,different mass ratios of functional materials and fertilizers were mixed into the facility soil.The effect of functional materials on soil properties and cucumber‘Deraite 398’physiological indicators was studied.The results showed that compared with the control treatment,the application of functional materials significantly increased the soil available phosphorus content,and significantly increased cucumber plant height,stem diameter,leaf area,chlorophyll a content,and cucumber net photosynthetic rate.However,functional materials have little impact on pH value,soluble salt content,available nitrogen and potassium content.From this,it could be concluded that functional materials had a significant promoting effect on the growth and development of cucumber plants,and their impact on the physicochemical properties of secondary saline soil still needed further research.
