| Abstract (English): |
The effects of biological organic fertilizer (S) and water-retaining agent (B) on cucumber growth and soil fertility under continuous cropping were studied with traditional total nutrient solution water soluble fertilizer as control (CK), so as to determine the appropriate amount of bio-organic fertilizer and its effect combined with water retention agent. The results showed that compared with CK,B +S treatment could promote the growth and development of cucumber plants,significantly increase EC value,contents of available phosphorus,organic matter,available nitrogen,and decrease soil pH value in 0—20 cm soil, the available phosphorus content in soil treated with B + S200 increased by 17.21%, the content of organic matter in soil treated with B + S400 increased by 62.74%, and the content of available nitrogen increased by 59.48% in the treatment of B + S600. Compared with CK,B + S treatment could promote the growth of roots,increase the photosynthetic rate and yield,yield increased by 5.37%—12.54% ;increase the contents of soluble solid, soluble sugar and vitamin C, which increased by 7.73—18. 18% ,15.08% — 15.20% and 44.48%—47.58%, respectively. Therefore, the combination of bio-organic fertilizer and water-retaining agent was better to repair soil and promote growth and development of cucumber, among which the effect of B + S200 treatment was the best.

以传统全营养液水溶肥为对照（CK），研究生物有机肥（S）与保水剂(B)对设施连作黄瓜生长和土壤肥力的影响，以确定生物有机肥的合适用量以及其与保水剂的配施效果。结果表明，B+S处理供肥以及保水、保肥效果较S处理更好。与CK相比，B+S处理可促进黄瓜植株生长发育；明显提高0~20 cm土壤的EC和速效磷、有机质含量，显著提高土壤速效氮含量，降低土壤pH值，其中B+S200处理土壤速效磷含量提高了17.21%，B+S400处理土壤有机质含量提高了62.74%，B+S600处理土壤速效氮含量提高了59.48%；促进根系的生长发育；提高叶片的光合速率；提高黄瓜产量，提高幅度为5.37%~12.54%；提高果实可溶性固形物、可溶性糖、维生素C含量，提高幅度分别为7.73%~18.18%、15.08%~15.20%、44.48%~47.58%。因此，生物有机肥与保水剂结合施用改善土壤、促进黄瓜生长发育效果更好，其中B+S200处理效果最好。 [ABSTRACT FROM AUTHOR] |
