在新疆辽阔的土地上,广泛分布着丰富的含腐植酸量较高的风化煤资源。新疆风化煤总腐植酸含量大于30％的矿点很多。北疆地区多数风化煤钙镁结合量不高,游离腐植酸可占到80％,pH值为4—5;南疆地区风化煤的钙镁结合量一般较高,游离腐植酸含量较低,pH为6—8。近年来,在农业学大寨群众运动中,我区推广使用风化煤腐植酸肥料取得了一定成效。一九七三至一九七六年,我们在米泉县水稻土上安排了施用风化煤的田间试验和盐化土、碱化土施用风化煤的盆栽试验。总结四年来的试验,我们体会
In Xinjiang vast land, widely distributed rich humic acid containing weathered coal resources. Xinjiang weathered coal total humic acid content of more than 30% of the mine many. Most of the weathered coal in northern Xinjiang is not high in calcium and magnesium, the free humic acid accounts for 80%, and the pH value is 4-5. The weathered coal in southern Xinjiang is generally high in calcium and magnesium combined with low levels of free humic acid, The pH is 6-8. In recent years, in the Daxia mass movement in agriculture, our district has made some achievements in promoting the use of weathered humic acid fertilizer. From 1973 to 1976, we conducted a field trial of weathered coal on paddy soils in Miquan County, and potted trials of saline soil and weathered coal on alkalized soil. Summarize the experiment in four years, we understand
