摘 要:為探究生物有机肥及氨基酸肥替代传统农家肥对水芹生长的影响,采用3种不同施肥处理(CK:基肥每667 m2施用腐熟的猪粪600 kg+追肥;T1:基肥每667 m2施用生物有机肥600 kg+追肥;T2:基肥每667 m2施用生物有机肥600 kg+丰根拓5 kg+追肥),测定水芹生长相关指标和营养成分。结果表明,(1)T2处理水芹产量最高,较CK显著增加51.87%;(2)与CK相比,T1和T2处理可以显著促进水芹株高和单株鲜质量的提升,显著增加分蘖数;(3)T1和T2处理的水芹亚硝酸盐含量显著低于CK;(4)各处理水芹不溶性膳食纤维含量高低依次为CK>T1>T2。聚类分析结果表明,各处理对水芹的影响可分为2类,T2处理为一类,CK和T1处理为另一类。与传统猪粪相比,施用生物有机肥和丰根拓氨基酸肥料显著促进水芹产量的提升,显著增加水芹的有效分蘖数,提升水芹维生素C含量,显著降低水芹亚硝酸盐含量及不溶性纤维含量。

Abstract: The field experiment was conducted to explore the effect of bioorganic fertilizer and amino acid fertilizer on the growth of Oenanthe javanica. Three treatments were set up: (1) CK: pig manure for base fertilizer + topdressing; (2) T1: bioorganic fertilizer for base fertilizer + topdressing; (3) T2: bioorganic fertilizer and amino acid fertilizer for base fertilizer + topdressing. The results showed that: (1) the yield of T2 was the highest, which is significantly increased by 51.87% compared with CK; (2) T1 and T2 could promote the plant height and fresh weight per plant, and the numbers of tillers under which were significantly increased; (3) the contents of nitrite in the plants treated by T1 and T2 were significantly lower than that in CK; (4) the contents of insoluble dietary fiber in each treatment were in the order of CK > T1 > T2; (5) cluster analysis showed that the effects of different treatments on Oenanthe javanica could be divided into two categories, CK and T1 belonged to the same class. Therefore, compared with the traditional pig manure, the application of bioorganic fertilizer and amino acid fertilizer could significantly improve the yield of Oenanthe javanica, increase the effective tillers, and reduce the contents of nitrite and insoluble fiber.

水芹[Oenanthe javanica (Bl.) DC.]属伞形科多年生草本植物,是我国传统特色水生蔬菜之一,其别名有:牛草、楚葵、刀芹等。水芹富含丰富的纤维素、微生素、矿物质等成分,具有清热、降血压、利尿等多重功效,深受广大消费者的喜爱[1]。目前,水芹的种植范围主要分布在长江流域及以南地区,其中以江苏省种植面积最大,也最为集中[2]。南京六合大圣水芹为南京地区特色蔬菜品种,以其“细、白、长、嫩、香、脆”的特点享誉大江南北[3]。……p>
