Abstract:Through field trials of three-stubble vegetable in one year,7 different kinds of fertilization modes(i.e.Applying none fertilizer,Chemical fertilizer applied as base manure,Chemical fertilizer applied half as base manure and half as additional one,Chemical fertilizer and dicyandiamide applied as base manure,Chemical fertilizer and dicyandiamide applied half as base manure and half as additional one,Applying chemical fertilizer and organic manure,Applying organic manure.) were conducted to tested the effects of using different kinds of fertilization modes on yield and nitrate's content of vegetable,and loss of nitrogen and phosphorus in vegetable field.Results showed that: Used two kinds of fertilization modes,such as "Applying chemical fertilizer and organic manure" and "Chemical fertilizer and dicyandiamide applied as base manure",not only relatively higher output and lower nitrate's content of vegetable could be gained,but also the lost amount of nitrate-nitrogen,ammonia-nitrogen and water-solubility phosphorus,which were carried by ground runoff from vegetable field during the session of planting,was obviously reduced.Consequently,Non-point Source Pollution from Agriculture resulting from vegetable field was cut down.Therefore,those two kinds of fertilization modes are worth of being popularized on vegetable production in the future.
