摘要
在大棚栽培条件下,开展微生物肥料在青菜上的应用效果研究。结果表明:增施生物有机肥和有机肥配施农用微生物菌剂均能够促进青菜植株生长,改善青菜农艺性状,提高青菜生物产量,增加青菜经济效益,同时也能增加土壤有机质、水解性氮、有效磷和速效钾含量。相比较而言,增施生物有机肥对促进青菜生长和增产效果更好,较不施对照增加叶片厚度16.3%、叶片总数14.5%和植株高度7.5%,提高青菜生物产量25.8%。就综合生产效益方面而言,有机肥配施农用微生物菌剂好于生物有机肥,其较不施对照增加效益9 524元·kg^(-1)。
The application effect of microbial fertilizer on Brassica rapa var.chinensis was studied under greenhouse cultivation.The results showed that increased application of organic fertilizer and organic fertilizer combined with agricultural microbial agents could promote plant growth,improve agronomic traits,increase biological yield and economic benefits of Brassica rapa var.chinensis,and also increase the contents of soil organic matter,hydrolyzed nitrogen,available phosphorus and available potassium.In comparison,increased application of bio-organic fertilizer had better effect on promoting growth and increasing yield of Brassica rapa var.chinensis.Compared with no application control,it increased leaf thickness by 16.3%,total leaf amount by 14.5%and plant height by 7.5%,and increased biological yield by 25.8%.In terms of comprehensive production benefits,organic fertilizer combined with agricultural microbial agents was better than bio-organic fertilizer,and its benefit increased by 9524 yuan per kilogram compared with no application.
