泥炭(草煤)、褐煤、风化煤中含有的腐植酸与土壤腐植酸有相似的结构,对土壤物理化学性状和农作物的作用也与土壤腐植酸相似。我省农民早就有利用泥炭改良土壤或把泥炭与厩肥堆沤施用于农田的习惯。从70年代,以来,我省农业和化工部门共同组织了省、地、县50余个科研单位对粮食作物、烤烟、甘蔗、茶叶、油菜、蚕桑、蔬菜、水果等进行了腐植酸类肥料的试验推广工作。1980至1986年,全省累计示范推广10
Humic acid contained in peat (grass coal), lignite and weathered coal has a similar structure to soil humic acid, and also has similar effects on soil physicochemical properties and crops as soil humic acid. Farmers in our province have long had the habit of using peat to improve the soil or to apply peat and manure to farmland. Since the 1970s, the agricultural and chemical departments of our province have jointly organized more than 50 research institutes in provinces, prefectures and counties to carry out humic acid-based fertilizers on food crops, flue-cured tobacco, sugar cane, tea leaves, canola, sericulture, vegetables and fruits Test promotion. From 1980 to 1986, the province had a total of 10 demonstration and promotion
