摘要
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%
Comparative experiments for utilizing decomposed water peanuts as basal manure was conducted on fluvo quic soil. It was found that the water peanut did not have weed problem when they were decomposed with 2 to 4% ammonium carbonate until stems fell off. The decomposed water peanuts could be used as basal manure for rice and wheat, and the humification rate was 0.18. The K efficiency of the water peanuts manure was higher than chemical K fertilizers. Consecutive use of the manure increased the yields of rice and wheat by 4 to 5%.
