在沿海潮土上设置沤制和肥效对比试验 .结果表明 ,水花生加其鲜体 2 %～ 4 %的碳铵沤制至茎自然脱落 ,不致再生形成草害 ,并可作稻、麦基肥 ,其腐殖化系数为 0 1 8.与等量钾相比 ,水花生供钾效果更好 ;连续还田 ,稻、麦增产 4 %～ 5% The results showed that the peanut plus 2% ~ 4% ammonium bicarbonate of fresh body could naturally fall off to the stem and could not be regenerated to form grass and could be used as rice and wheat base fertilizer , The humification coefficient of 0 1 8. Compared with the same amount of potassium, peanut water supply better; continuous return of rice, wheat yield 4% to 5%
