通过布置有机肥(鸡粪和牛粪按1∶1混合而成)的不同用量试验,研究有机肥对土壤理化性质及番茄生长的影响,结果表明:施用有机肥可提高土壤中硝态氮、有效磷和速效钾的含量,分别提高56.4%~98.7%、9.5%~58.2%15.1%~50.6%;随有机肥施用量的增加,土壤碳氮比降低的程度就越明显,土壤碳氮比降幅为1.82%~23.53%;施用有机肥可使番茄产量增加10.5%,并可提高番茄苗期的开花比例,亩施2t和3t有机肥的处理显著高于不施有机肥的对照处理,分别增产22.2%、16.7%,北京设施番茄种植以亩施2 t有机肥较为适宜。
The effects of organic manure on physical and chemical properties of soil and growth of tomato were studied by applying different amount of organic manure (chicken manure and cow manure were mixed by 1: 1). The results showed that organic manure could increase nitrate nitrogen in soil Phosphorus and potassium increased by 56.4% -98.7% and 9.5% -58.2%, respectively, from 15.1% to 50.6%. With the increase of organic manure application, the soil carbon and nitrogen ratio decreased more obviously, and the ratio of soil C and N decreased And 1.83% ~ 23.53% respectively. The application of organic fertilizer increased the yield of tomato by 10.5%, and increased the flowering percentage of tomato seedling. The treatment of 2t and 3t organic fertilizer in Mushi was significantly higher than the control without organic fertilizer, 22.2% and 16.7% respectively. It is more suitable for the Beijing facility to plant 2 ton of organic fertilizer with Mushi.
