生物有机肥对养心菜品质和产量的影响

利用研制的包含多种功能菌(白黄链霉菌TD-1、固氮菌JZ1、无机磷分解菌JWP1、有机磷分解菌JP12、解钾菌JK1)的菌剂对不同原料配比制成的农业有机废弃物堆肥进行二次发酵，制得具有促生功能的生物有机肥，并用于扦插养心菜种植中，探究生物有机肥对养心菜产量和品质的影响。结果表明：相较于不施肥组和未二次发酵处理的有机肥组，不同原料配比的二次发酵生物有机肥对养心菜的产量和品质有明显提高。在种植70 d后，N3M生物有机肥组的养心菜生长指标较佳，须根分支数、单株产量最高，分别为15.00根和11.89 g，株高增量达到456.10%，显著高于不施肥组。在品质指标中，N3M处理组养心菜的单宁含量为2.19 mg·kg^-1，较不施肥组降低了40.5%，养心菜涩味明显降低，同时该组养心菜的VC和总黄酮含量较不施肥组和未二次发酵组也有所提高。综上所述，施用适宜配方的生物有机肥能促进养心菜生长，同时提高其品质和产量。因此，生物有机肥可作为一种绿色环保肥料用于农业生产。

Effect of Bio-organic Fertilizer on Quality and Yield of Sedum aizoon L.

The biological organic fertilizer with promoting function was prepared by secondary fermentation of agricultural organic waste composting made with different raw material ratios using the microbial inoculum containing a variety of functional bacteria (Streptomyces alboflavus TD-1, nitrogen fixing bacteria JZ1, inorganic phosphorus decomposing bacteria JWP1, organic phosphorus decomposing bacteria JP12 and potassium decomposing bacteria JK1) and used for planting of cuttage Sedum aizoon L. to explore the effects of the biological organic fertilizer on the yield and quality of the Sedum aizoon L.. The results showed that compared with no-fertilization group and no-secondary fermentation organic fertilizer group, the bio-organic fertilizer after secondary fermentation with different proportions of raw materials significantly improved the yield and quality of Sedum aizoon L.. After 70 days of planting, the growth index of cabbage was better in the N3M bio-organic fertilizer group, with the highest branch number of fibrous root and yield per plant, which was 15.00 and 11.89 g, respectively. The plant height increment reached 456.10%, significantly higher than that in the no-fertilization group. Among the quality indexes, the tannin content of Sedum aizoon L. in the N3M treatment group was 2.19 mg·kg -1, which was 40.5% lower than that in the no-fertilization group, and the astringency of Sedum aizoon L. was significantly reduced, the VC and total flavonoid contents of Sedum aizoon L. were also higher than those in the no-fertilization group and the no-secondary fermentation group. In summary, the application of bio-organic fertilizer could promote the growth of Sedum aizoon L. and improve its quality and yield. Therefore, that biological organic fertilize with appropriate formula can be used for agricultural production as a green and environment-friendly fertilizer.
