腐植酸是以泥炭、风化煤为原料提炼而成的一种新型农用有机物。近年国内外将其用于多种农作物上,取得了良好增产效果。1984—1986年,我们于小麦孕穗至扬花期,在大田选择生长整齐、长势均匀的地段进行叶面喷施腐植酸试验,小区面积187.5—200.0平方米,1984和1985年每亩每次喷施腐植酸20克+尿素200克+磷酸二氢钾135克+水20公斤,1986年每亩每次喷腐植酸20克+水20公斤,皆共喷两次,两次间隔10天,以不喷腐植酸为对照。
Humic acid is peat, weathered coal as raw material extracted from a new type of agricultural organic matter. In recent years, it is applied to many kinds of crops at home and abroad, and has achieved good yield-increasing effect. 1984-1986, we booting wheat to flowering, in the field choose growing neat, uniform growth of foliar spray humic acid test area of 187.5-200.0 square meters plot area, 1984 and 1985 per acre spray Humic acid 20 grams + 200 grams of urea + potassium dihydrogen phosphate 135 grams + water 20 kilograms per acre in 1986 1986 20 grams of phytosanitrate + water 20 kg, were spray a total of two times, twice an interval of 10 days to not Spray humic acid as a control.
