【摘要】 东北地区玉米和水稻秸秆产量丰富,而秸秆灰和稻壳灰中富含多种可被作物利用的维生素及有机质,为提高生物质灰的利用率,实现农业的可循环发展,本文使用秸秆灰和稻壳灰两种不同浓度生物质灰浸提液(5倍、10倍和50倍稀释液)对黄瓜种子进行室内法培养,研究了不同浓度的两种生物质灰对黄瓜种子的萌发及幼苗素质的影响。结果表明:不同浓度的两种生物质灰浸提液对黄瓜种子的萌发都具有一定的促进作用,当两种生物质灰浸提液浓度为5倍时黄瓜种子的幼苗生长情况最好,这说明此浓度的生物炭浸提液最适宜黄瓜种子的萌发。更多还原

【Abstract】 Maize and rice straw yield is abundant in Northeast China,while straw ash and rice husk ash are rich in vitamins and organic matter which can be used by crops.In order to improve the utilization rate of biomass ash and realize the recyclable development of agriculture,two different biomass ash extracts,straw ash and rice husk ash,were used for indoor germination of cucumber seeds.The effects of two different concentrations of biomass ash on the germination and seedling quality of cucumber seeds were studied.The concentration of straw ash and rice husk ash extracts was 5 times,10 times and 50 times of the original solution.The experiment showed that the two kinds of biomass ash extracts at different concentrations could promote the germination of cucumber seeds.When the concentration of the two kinds of biomass ash extracts was 5 times,the growth of cucumber seedlings was the best.This indicated that the biochar extract of this concentration was the most suitable for cucumber seed germination..更多还原
