爆破整地对栗钙土理化性质的影响

Study on the Explosive Technique Influence on the Physical and Chemical Properties of Chestnut Soil

研究了在钙积层较明显的栗钙土地区用爆破法整地对土壤物理性质、化学性质、碳酸钙含量及钙积层深度的影响.结果表明:爆破整地可以改善栗钙土的理化性质,使钙积层深度下移,不同药量改善效果不同,试验中炮眼80 cm药量300 g改善效果最佳.

Studied on the explosive technique influence on the physical and chemical properties, the content of calcium carbonate and the depth of calcic horizon of the chestnut soil zone which is rich in calcic horizon in this paper, the results are following： the explosion technique can improve the physical and chemical properties of chestnut soil and make the depth of calcic horizon descend. The improving effect depends on the amount of explosive,and the best amount of explosive in 80cm hole is 0.3kg in our experiments.
