摘要： 为调控营养液中营养元素缓控释放，提高植物营养液的肥效，进而提高水培作物的产量，降低水培成本，向植物营养液中添加了一种新型肥料增效剂聚天冬氨酸(PASP)，考察了植物营养液中添加PASP对水培作物生长发育的影响。试验以日本园艺配方均衡营养液为空白对照组，采用营养液膜水培技术(NEF)，对小白菜和芹菜进行了不同添加量PASP的营养液水培试验以及大棚无土栽培扩大试验。结果表明，营养液中添加一定量PASP对小白菜和芹菜的营养物质累积有明显的促进作用，并且可以很好地降低水培蔬菜中硝酸盐的含量。实验室水培小白菜30天单株干重增产9.51%，硝酸盐含量相比于空白组下降了50.93%，Vc含量为空白组的1.86倍；芹菜单株湿重增产45.07%，单株干重增产46.29%，硝酸盐含量相比于空白组降了29.94%，Vc含量为空白组的1.27倍。大棚水培芹菜30天单株湿重增产8.5%，干重增产19.5%。故植物营养液中添加一定量的PASP可以明显提高营养液的肥效，在蔬菜水培中达到增产增收、提高蔬菜品质的作用，试验得出1.5%是PASP的一个较为合适的添加量。

Abstract: [Objective]In order to release the nutrient elements of solution sustainablely and controllably , improve plant nutrition liquid fertilizer and hydroponic crop yields, reduce the cost of hydroponic, a new fertilizer synergist-polyaspartic acid (PASP) was added to the plant nutrition solution, investigating the effects on the growth of hydroponic plants.[Method]Using hydroponic nutrient film technique (NEF) and the balanced nutrient solution formula as the blank control group,hydroponic nutrient solution and green-house soilless culture expansion tests were conducted on Chinese cabbage and celery with different polyaspartic acid(PASP) dosages. [Result]The results showed that the nutrition solution with a certain amount of PASP had great effects on the growth of Chinese cabbage and celery, and could well reduce the content of nitrate in vegetable hydroponics. Drying weight of 30d-cultivated hydroponic cabbage in the laboratory increased 9.51 %. Compared with the control group, nitrate content decreased 50.93 %; VC content has an increase of 1.86 times. Celery’s wet weight per plant increased 45.07% and dry weight per plant increased 46.29 %. Nitrate content, compared with the control group ,dropped by 29.94 %, VC content is 1.27 times of the control group. The wet weight of green-house hydroponic celery 30d-cultivated increased 8.5 % and the dry weight increased by 19.5 %. [Conclusion]The solution with a certain amount of PASP will increase the production of hydroponic vegetables and improve the quality of vegetables. A large number of experments showed that 1.5 % PASP is the best dosage.
