近年来,腐植酸混合肥已广泛应用于粮食作物和多种经济作物并取得了良好的效果。为探讨腐植酸混合肥在柑桔生产上的肥效及综合经济效益,我们于1985年——1986年在南城县青山园林场进行柑桔施用腐植酸混合肥试验,并与等养分的饼肥、无机复化肥作对比,现将试验结果总结如下: 一、材料与方法供试的腐植酸N、P、K混合肥(下简称腐混肥)为南昌腐植酸厂生产。N、P、K含量比为6∶6∶6,含游离腐植酸19.7％。试验小区设在南城县万坊乡青山园林场,选用地势较平坦,供试土壤为第四纪红
In recent years, humic acid fertilizer has been widely used in food crops and a variety of cash crops and achieved good results. In order to explore the fertilizer effect and comprehensive economic benefit of humic acid fertilizer in citrus production, we conducted humic acid mixed fertilizer experiment on citrus in Qingshan garden field of Nancheng County from 1985 to 1986, and compared with other nutrients such as cake fat, Fertilizer for comparison, now the test results are summarized as follows: First, the material and method for the test of humic acid N, P, K fertilizer (hereinafter referred to as rotten fertilizer) for humic acid plant production Nanchang. N, P, K content ratio of 6: 6: 6, containing 19.7% of free humic acid. The experimental plot is located in Qingshan Garden, Wanfang Township, Nancheng County, with a flat topography for the Quaternary Red
