Title: Study on Profile Character of pH and the Organic Matters in the Facility Cultivation Soils in Dongling Area
Abstract: This paper studies the pH value and the organic matters in the facility cultivation soils collected from Qianjingsai and Lixiang in Dongling area.The results of the study indicate that compared with the control group,protected soil acidification is quite common,soil acidification degree is expanding.From profile,protected soil acidification is the whole soil acidification.Individual soil acidification is serious,ph value is lower than the critical point of vegetable crops can adapt.This has posted a threat to the normal growth of crops.Along with the increase of plantation years,Ph value is gradually reduced,causing serious soil acidification.The organic matters in the facility cultivation soils of Dongling area are obviously higher than those of matured reference soil.Along with the increase of plantation years,this trend increases more obviously.Because of using single species organic(unripe),the organic matters of soil increase,but the environmental effect of the organic matters are lower and lower.
