【摘要】 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4~5 d,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。更多还原

【Abstract】 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-organic fertilizer 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.更多还原
