煤化肥(腐植酸铵)是我国劳动人民创造的一种新的肥料品种。1974年,我们对煤化肥的肥效在复种小糜子地上进行了初步试验,取得了较好结果,现将试验情况简报于后。一、肥料来源系由区化工研究所用白芨芨沟无烟风化煤(腐植酸总含量25.8％)经粉碎在室温下加氨水(浓度15.1)土法制得。按加入氨水多少分两种规格: 风化煤100斤加氨水30斤(以下简称30％氨化煤); 风化煤100斤加氨水15斤(以下简称15％氨化煤)。二、田间试验试验地前茬为墨西哥小麦,亩产700余斤,地力均匀,麦收前于7月10号灌麦黄水,麦收后犁地一次,耙地两次,于7月20日施肥播种,品种为当地小糜子。试验未施其它基肥,全
Coal fertilizer (ammonium huminate) is a new type of fertilizer created by the working people in our country. In 1974, we conducted a preliminary test of fertilizer efficiency of coal fertilizer on the ground of small-scale mulch and achieved good results. We are now briefing the test results. First, the source of fertilizer by the District Institute of Chemical Research with Bajizigou ditch smoke-free weathering coal (total humic acid content of 25.8%) by crushing at room temperature with ammonia (concentration 15.1) soil method. According to join the number of ammonia divided into two sizes: 100 kg of weathered coal plus ammonia 30 kg (hereinafter referred to as 30% ammoniated coal); weathered coal 100 kg plus 15 kg of ammonia (hereinafter referred to as 15% ammoniated coal). Second, field trials The former crop of Mexican wheat, more than 700 pounds per mu, soil fertility, wheat received before the July 10 irrigation of yellow water, wheat harvest after plowing once, raking twice, on July 20 fertilization Seeding, the variety of small local millet. Test not applied to other basal, full
