Solid Waste Configuration Of Soil Ameliorators Experiments

Along with the rapid development of China's economy, environmental problems and the damage of soil by our government and problems has been highly relevant departments, and the national economic and social development "11th five-year" plan ecological improvement and environmental protection in the special planning. This paper based on the solid waste reuse and poor soil arid improvement, phosphorous gesso, two for raw materials and fly ash soil ameliorators for preparation of sludge.Aiming at eight goals in two stages of soil experiment research, the ratio of soil improver through pH value of the critical ratio, dock planner - repeatedly screening method of optimal proportioning three improver raw sewage sludge, fly ash, (three mass ratio of phosphorous gesso 600:320:1; the soil quality improver and target than for 8). Experimental results show that the soil ameliorators eight goals in the fertility of soil nutrient content and etc, will be improved greatly improve soil parameters and the national goal of soil 2 levels GSCC standards can be seen, the second phase experimental improved eight goals soil nitrogen, phosphorus, potassium, soil organic matter content meet the national standards, and 2 for parameters of a low base target soil improvement effect (effective N topped 629mg/kg, effective P topped 650 mg/kg, effective K highest 62 mg/kg, organic highest 15.4 per cent). Through theoretical calculation and practical data of test data analysis of soil parameters errors made in the first two stages (including the average error of the maximum effective nitrogen, 876.032 mg/kg) - that the soil parameters, and the random error of the system error, and summarizes the main reason the mixing ratio of raw material, improvers soil nitrogen, phosphorus, potassium, organic matter content in the soil improver, mixing, soil quality percentage of model parameters between error formula. In order to verify this experiment of eight goals soil ameliorators for improvement, this paper carried out experiments, potted plant corn experimental results show that the improved target soil relative to the average rate of soil, the higher goal, the average height of 6.7 shoot higher average growth rate 35.11 mm, 3.32 30d/mm above, therefore, improved obviously superior to target the soil properties of soil, this experiment target improvement of soil ameliorators effect is remarkable.
