【摘要】 通过田间小区试验和室内分析,研究了硅钾钙镁肥在黑龙江垦区寒地水稻上的施用效果。结果表明,施用硅钾钙镁肥使水稻抽穗期和成熟期比对照提前1~2 d,能明显提高水稻抗病、抗寒和抗倒伏能力等;硅钾钙镁肥在该地区水稻上的适宜施用量为300~450 kg/hm2,可增产4%~10%,增加效益645~1 605元/hm2。更多还原

【Abstract】 Effect of fused calcium-magnesium-silicon potash fertilizer on paddy rice in Hei-longjiang reclamation cold area loas studied by field plot experiment and laboratory analysis.The results showed that the use of fused calcium-magnesium-silicon potash fertilizer could accelerate maturation of paddy rice,making its heading stage and maturation date ahead for 1-2 days.300-450kg/ha loas recommended for rice in local area,which can increase the output by 4% to 10%.Fused calcium-magnesium-silicon potash fertilizer can remarkably improve the resistanceabilities of crops against diseases,coldness and lodging.更多还原
