将聚氨酸增效剂与常规肥料混合制成聚氨酸肥料，通过盆栽试验，研究盐渍土壤中聚氨酸肥料对普通白菜品种四季小白菜和苏州青生长、土壤微生物量及土壤酶活性的影响，以期为聚氨酸新型肥料在盐渍土壤中的推广应用提供科学依据。结果表明：与常规肥料相比，施用聚氨酸肥料后，四季小白菜的根长和单株质量分别增加36.81%和36.11%，苏州青分别增加19.70%和27.57%，四季小白菜和苏州青叶绿素总量分别提高31.00%和27.27%，土壤呼吸强度分别提高69.48%和28.57%，土壤脲酶和蔗糖酶活性提高了19%～32%，土壤微生物量氮和微生物量磷增加了8%～33%，代谢熵提高了14%～40%。聚氨酸肥料均可促进参试普通白菜的生长，且在四季小白菜上的施用效果略优于苏州青。
將聚氨痠增效劑與常規肥料混閤製成聚氨痠肥料，通過盆栽試驗，研究鹽漬土壤中聚氨痠肥料對普通白菜品種四季小白菜和囌州青生長、土壤微生物量及土壤酶活性的影響，以期為聚氨痠新型肥料在鹽漬土壤中的推廣應用提供科學依據。結果錶明：與常規肥料相比，施用聚氨痠肥料後，四季小白菜的根長和單株質量分彆增加36.81%和36.11%，囌州青分彆增加19.70%和27.57%，四季小白菜和囌州青葉綠素總量分彆提高31.00%和27.27%，土壤呼吸彊度分彆提高69.48%和28.57%，土壤脲酶和蔗糖酶活性提高瞭19%～32%，土壤微生物量氮和微生物量燐增加瞭8%～33%，代謝熵提高瞭14%～40%。聚氨痠肥料均可促進參試普通白菜的生長，且在四季小白菜上的施用效果略優于囌州青。

To provide scientific proof for the population and application of poly amino acid fertilizer in saline soil,the effects of poly amino acid fertilizer on 2 pakchoi(Brassica campestris L. var. communis Tsen et Lee)varieties‘Sijiqingxiaobaicai’and‘Suzhouqing’growth and soil microbial biomass and soil enzymes activities in saline soils were studied by pot culture experiment. The results showed that compared with conventional fertilizer, the application of poly amino acid fertilizer could significantly increased the root length and single plant weight in‘Sijiqingxiaobaicai’by 36.81% and 36.11%,respectively,and by 19.70% and 27.57% ,respectively in‘Suzhouqing’.The contents of chlorophyll,soil respiration intensity,urease and sucrase activities,soil microbial biomass nitrogen and microbial biomass phosphorus in‘Sijiqingxiaobaicai’and‘Suzhouqing’applied poly amino acid fertilizer were all higher than that applied conventional fertilizer by 31.00% and 27.27%, respectively in chlorophyll,by 69.48%and 28.57%,respectively in soil respiration intensity,by 19%-32%in urease and sucrase activities,by 8%-33%in soil microbial biomass nitrogen and microbial biomass phosphorus, by 14%-40%in metabolism entropy. The application of poly amino acid fertilizer could promote the growth of two varieties of pakchoi,and the effect on‘Sijiqingxiaobaicai’was slightly better than that of‘Suzhouqing’.
