复合肥造粒对玉米吸肥规律的影响

THE EFFECT OF THE GRANULAR MAKLNG OF COMPLEX FERTILIZER ON ABSORB LAW OF CORN FERTILIZER

摘要:

通过盆栽试验,我们对施用原状复合肥,粒状复合肥和不施化肥的玉米植株,在不同生育时期测定氮、磷、钾的吸收量。本文明确了复合肥造粒能够减慢养分释放速度,增强持续供肥能力。

Abstract:

Through pot experiments, which were given original form complex fertilizer, granularcomplex fertilizer and non fertilizer, the capacity of nitrogen, phosphorus, potassium absorbed by corn plants was measured in different vegetation period. Tt was shown that thegranular making of comp|ex fertilizer could retard the releasing speed of nutrient andstrengthen lengthen the period of fertilizer supplement.
