Soil Nutrient Variation in Greenhouse Soil from Haicheng Municipality, Liaoning Province

Abstract:

Soil nutrient in greenhouse soil was studied in Haicheng Municipality, Liaoning province. Results showed that the soil nutrient including organic matter, total nitrogen, total phosphorus, alkaline hydrolysis nitrogen, available phosphorus and available potassium presented parabolic curve change with increasing cultivating years. The highest contents all appeared in 8 years, which are 3.2 and 2.8 times higher than those in open field at 0-20 cm and 20-40 cm depth, respectively. The vertex of nitrate and soluble salt were also appeared in 8 years. Correlation analysis suggested the relationships among nutrients were very significant. It is also suggested the salinization of soil was the inevitable result of the excessive organic fertilizer and chemical fertilizer.
