生物有机肥在双季稻上的应用试验

Experiment of applying bio-organic fertilizer to paddy field of double-cropping rice

在水稻上进行施用生物有机肥试验,结果表明：施用等量NPK的条件下,生物有机肥处理较常规施肥处理的出苗高峰延迟4～5d,最高茎蘖数减少,成穗率提高,早稻增产3.26％,晚稻增产4.21％;且有利于磷元素的吸收,促进水稻对Cu、Zn、Cd、As等金属元素的积累.

Experiment of applying bio-organic fertilizer to rice field was carried out. The results showed that, under the equivalent amount of N, P and K fertilizers and compared with conventional fertilization treatment, applying bio-orgauic fertil- izer could delay the growing peak of seedlings by 4 - 5 days, decrease the maximum number of neck tillers, raise the spike rate, increase the yield of early rice and late rice by 3.26% and 4.21% respectively; favor the uptake of phosphorus, and promote the accumulation of Cu,Zn,Cd,As in rice plants.
