摘　　要：针对海藻工业废渣有机肥的性质,分别从小白菜种子萌发、促生长及抗盐碱三方面对有机肥的肥效进行研究。结果表明,在发芽率实验中,有机肥稀释1 000倍的小白菜发芽率和发芽势最好,在5‰的盐溶液中,稀释3 000倍效果最好。生长实验中,普通花园土中,海藻渣有机肥的最佳添加量为2‰,发芽率比对照组提高28.9%,盐碱土中,添加1‰海藻渣有机肥效果最好,明显改善小白菜生长情况,发芽率可达到对照组的3倍。According to the nature of the algae waste organic fertilizer,the three areas of the Chinese cabbage seed germination,growth and resistance salt and alkali was studied for organic fertilizer effect.The results showed that：in experiments of germination percentage,the 1 000 times liquid of organic fertilizer could promote seed germination and the young sprout growth evidently,in 5‰ salt solutions,the 3 000 times liquid of organic fertilizer was the best.In experiments of growth,the optimum quantity of organic fertilizer was 2‰ in ordinary soil,the germination rate increased by 28.9% compared to the control group.In saline-alkali soil,1‰ organic fertilizer was added,and the germination rate was three times as much as the control group.
