| 摘要 | [Objectives]This study was conducted to promote the rational use of bioorganic fertilizers.[Methods]Stanley bioorganic fertilizer was selected to investigate the laws and characteristics of the effects of bioorganic fertilizer on spinach growth with different application rates in a short term and found out the precise application rate.[Results]As the application rate of bioorganic fertilizer increasing,the emergence rate of spinach decreased.The total weights and leaf areas of spinach plants treated with different application rates of bioorganic fertilizers were all higher than those of the control check(CK).The total weights and leaf areas of spinach plants applied with bioorganic fertilizer at different rates were all higher than those of the CK.The total weight of spinach plants increased linearly with the application rate of bioorganic fertilizer increasing among treatments,while the leaf area fluctuated with the increase of bioorganic fertilizer concentration among various treatments.The average root volumes and average diameters of treatments applied with bioorganic fertilizer at different rates were all higher than those in the CK,but the average root length showed a different trend.The average root length was higher in the CK than in various bioorganic fertilizer treatments in the early growth period,but the differences of various treatments from the CK gradually decreased in the middle period,and in the later period,the root length of spinach treated with organic fertilizer gradually exceeded the CK.[Conclusions]This study provides a theoretical basis for the rational application of bioorganic fertilizers in spinach production.收 |
