摘　　要：研究不同浓度的矿物源腐植酸钾处理对水稻种子萌发情况及幼苗相关生理指标变化的影响,为腐植酸科学应用提供依据。以水稻种子为试验材料,以蒸馏水为对照,配置不同浓度的矿物源腐植酸钾溶液(50、100、200、300、400、500 mg/L)进行浸种,通过盆栽试验,测定种子发芽率、发芽势、发芽指数以及幼苗的株高、根长、根粗、鲜重和干重等指标。结果表明:50~500 mg/L腐植酸钾浸种在不同程度上促进了水稻种子的萌发,有效提高了种子发芽势、发芽率、发芽指数,促进了株高、根长的生长及幼苗鲜重和干重的积累。本试验条件下,腐植酸钾浓度为500 mg/L时效果最佳。The effects of diff erent concentrations of mineral potassium humate on rice seed germination and changes in seedling-related physiological indicators to provide basis for the scientific application of humic acid.Using rice seeds as the test material and distilled water as the control,different concentrations of mineral potassium humate solutions(50,100,200,300,400 and 500 mg/L)were prepared for seed soaking.Through pot experiments,the seed germination rate and germination potential,germination index,as well as plant height,root length,root diameter,fresh weight and dry weight of the seedlings were determined.The results showed that seed soaking with 50~500 mg/L potassium humate promoted the germination of rice seeds to varying degrees,effectively improving seed germination potential,germination rate,germination index,promoted growth of plant height and root length,and accumulation of fresh and dry weights of seedlings.Under the test conditions,the best effect was achieved when the concentration of potassium humate was 500 mg/L.
