【摘要】：以濱海鹽堿地31年生刺槐純林為對象,研究了刺槐林不同土層土壤水鹽年份變化,土壤酶活性及養(yǎng)分的季節(jié)變化,分析了年降水與土壤性狀的相關(guān)性。結(jié)果表明,表層土壤含鹽量低,深層土壤含鹽量高,含水量與含鹽量呈負相關(guān);隨著土層逐漸加深,土壤酶活性逐漸減弱,土壤養(yǎng)分含量逐漸下降;年降水主要集中在夏季,占全年降水的66%。不同土層含水量、含鹽量、土壤酶活性及養(yǎng)分存在明顯相關(guān)性,且與降水呈顯著相關(guān)。
[Abstract]:The year variation of soil water and salt, the seasonal variation of soil enzyme activity and nutrient in different soil layers of Robinia pseudoacacia forest were studied, and the correlation between annual precipitation and soil properties was analyzed. The results showed that the surface soil had a low salt content and the deep soil had a high salt content, and the water content was negatively correlated with the salt content. With the deepening of the soil layer, the enzyme activity of the soil gradually decreased, the soil nutrient content gradually decreased, and the annual precipitation was mainly concentrated in summer. It accounts for 66% of the annual precipitation. Soil water content, salt content, soil enzyme activity and nutrient were significantly correlated with precipitation.
