马铃薯渣有机肥对土壤结构及芹菜品质和产量的影响

Effect of Potato Waste Organic Fertilizer on Soil Structure and Celery Yield and Quality

以"皇后"芹菜为试材,采用田间试验法,以不施肥为对照,研究了未发酵马铃薯渣、马铃薯渣有机肥、N-P-K复合肥对土壤结构及芹菜品质和产量的影响。结果表明:与对照相比,施用马铃薯渣有机肥可使土壤有机质含量增加2.58g/kg、全氮增加0.06g/kg、全磷增加0.03g/kg、碱解氮增加2.12mg/kg、速效磷增加10.11mg/kg、速效钾含量增加42.75mg/kg,对土壤全盐和pH没有显著影响;施用马铃薯渣有机肥可使芹菜株高、叶绿素含量、干物质量以及产量均显著高于对照及未发酵的马铃薯渣,叶绿素含量及干物质量显著高于N-P-K复合肥,说明马铃薯渣有机肥具有良好的肥效,能够促进芹菜生长。

Taking the celery as material, the effect of unfermented potato residue, potato residue organic fertilizer, as well as N-P-K compound fertilizer on soil structure and quality and yield of celery were studied in the open field,with no fertilizer as control. The results showed that the content of potato residue organic fertilizer, application of organic matter in the soil than the control increased 2. 58 g/kg,total nitrogen increased 0. 06 g/kg,total phosphorus increased 0. 03 g/kg,available nitrogen, available phosphorus increased 2. 12 rag/kg, 10. ll rag/kg respectively, 42. 75 rag/kg of available potassium, soil and total salt and pH had no significant effect. Application of potato residue organic fertilizer make celery plant height, chlorophyll content, dry weight and yield were significantly higher than those of control and unfermented potato residue, chlorophyll content and dry weight were significantly higher than that of N-P-K compound fertilizer, organic fertilizer that potato slag had good effect, and it could promote the growth of celery.
