水肥一体化对大棚土壤生态及黄瓜生长、 产量和品质的影响
Effects of water and fertilizer integration on soil ecology and cucumber growth, yield and quality in greenhouse
摘要
Abstract
Taking the cucumber in greenhouse as research object, the effects of water and fertilizer integration technology and conventional water and fertilizer management technology (control) on soil physical and chemical properties,soil enzyme activity and cucumber growth,yield and quality were compared. The results showed that at different growth stages of cucumber, the nutrient content of soil treated with water and fertilizer integration technology was higher than that of the control. The contents of organic matter, alkali-hydrolyzed nitrogen,available phosphorus and available potassium in soil were 29. 22％ ,15. 19％ ,12. 07％ and 31. 68％ significantly higher than those of the control at seedling stage, respectively. Compared with the control, the contents of organic matter, alkali-hydrolyzed nitrogen, available phosphorus and available potassium in soil increased by 1. 42％ ,17. 4％ ,4. 96％ and 25. 67％ at uproot stage, respectively. The total salt content and EC value of soil decreased,and pH changed little. The activities of soil cellulase and soil catalase were enhanced by water and fertilizer integration technology. The activity of soil cellulase was 10. 41％二, 47. 55％ , 28. 51％ and 40. 58％ higher than that of the control at the 4 growth stages of cucumber, respectively. The activity of soil catalase was the highest at the full fruit stage,whch increased the intensity of soil microbial activity. Water and fertilizer integration technology could significantly promote the growth of cucumber plants, the plant height, stem diameter,leaf number and total leaf area of cucumber increased by 16. 67％ , 12. 5％ , 16. 64％ and 25. 82％ respectively compared with the control. The yield of cucumber was 17. 12％ higher than that of the control. The contents of VC, soluble protein and soluble sugar in fruits increased by 22. 44％ , 7. 82％ and 9. 06％ respectively compared with the control, while the nitrate content decreased. Water and fertilizer integration technology could save fertilizer and water,and increase economic benefits.关键词
