酸化土壤改良剂
摘要：
本发明提供了一种酸化土壤改良剂，涉及土壤改良技术领域，其各组分的重量配比为：乙二胺四乙酸铁钠11%、发酵锯末粉29%、红糖粉4.5%、60目的磷矿粉7%，糖醇镁13%、硫酸钾4.5%、黄腐酸钾2.5%，余量为40目的木炭粉。在本发明提供的酸化土壤改良剂中，锯末粉及红糖粉在乙二胺四乙酸铁钠、糖醇镁作用下可持续变为腐殖酸，不断改善土壤团粒结构，此外，本发明通过添加木炭粉、红糖粉及黄腐酸钾，进一步改良了土壤团粒结构，疏松了土壤，提高了土壤的保水保肥能力，同时还提高了土壤中有机质的含量，有利于酸化土壤中植物的根系发育，提高植物的生长速度。
摘要（英）：

The invention provides an acidified soil improver and relates to the technical field of soil improvement. The acidified soil improver comprises the following components by weight percent: 11% of ferric sodium edelate, 29% of fermented saw dust, 4.5% of brown powdered sugar, 7% of 60-mesh powdered rock phosphate, 13% of sugar alcohol magnesium, 4.5% of potassium sulphate, 2.5% of potassium fulvic acid and the balance of 40-mesh charcoal dust. In the acidified soil improver provided by the invention, the saw dust and the brown powdered sugar can continuously become humic acid under the effects of ferric sodium edelate and sugar alcohol magnesium and can continuously improve the soil aggregate structure. Besides, the charcoal dust, the brown powdered sugar and the potassium fulvic acid are added, so that the soil aggregate structure can be further improved, the soil can be loosened, the moisture and fertility retention capacity of the soil can be promoted, meanwhile, the contents of organic matters in the soil can be increased, the root development of plants in the acidified soil is benefited, and the growth rate of the plant can be increased.
