| 摘 要： | 通过室内模拟培养试验,研究了有机肥与尿素配施对设施土壤盐分的影响.结果表明:(1)设施土壤的含盐量和电导率均随着施肥后培养时间的延长,呈先升高后降低再升高的趋势.培养15～30 d较高,30～60 d降低,60 d后又缓慢升高.设施土壤含盐量与有机肥施用量旱极显著正相关,而与尿素用量无明显的相关性;电导率则与尿素和有机肥施用最均有极显著正相关.(2)施用尿素不同程度增加了K+、Na+、Ca2+、Mg2+、NO3-的含量,施用有机肥显著增加了K+、Na+、Cl-的含量,设施和露地土壤盐分总量和离子组成差异不显著.另外研究了土壤盐分总量和电导率分别与K+、Na+、Ca2+、Mg2+、SO42-、Cl-等含量的相关性,均呈极显著正相关.

| Abstract: | Absorption of crops,nutrient efficiency and salt accumulation of soils were great influenced by interaction of different nutrition or soil salinity ion.It is very important to study the influences of interaction of several fertilizers concurrently in soils on salt content and ion com-position for enhancing fertilizer use efficiency and regulating nutrient balance and salt content in greenhouse cultivation system.Thus,in this research,the effects of interaction between inorganic fertilizers and manure on sal... |
