摘要
番茄连续多年重茬种植后,土壤易发生土传病害,地力水平降低,直接影响了番茄的正常生长,降低了番茄的产量和品质。通过使用微生物菌剂可以减少土传病害,改良土壤,增加土壤中有益微生物的多样性,提高番茄产量和品质。本试验设计四个处理:施用微生物菌剂灭活微生物菌剂、常规施肥、空白对照,研究微生物菌剂在番茄上的肥效试验,结果发现,微生物菌剂能显著改善番茄生物学性状,使果实横纵径、单果重增大;增强对枯萎病、青枯病的抗性;提高番茄的产量和经济效益,比常规施肥增产6.45%,比空白对照增产44.67%。
After tomato was planted repeatedly for many years, soil-borne diseases were easy to occur and the soil fertility level was reduced, which directly affected the normal growth of tomatoes and reduced the yield and quality of tomatoes. The use of microbial agents can reduce soil-borne diseases, improve soil, increase the diversity of beneficial microorganisms in soil, and improve tomato yield and quality. The results of this experiment were compared with those of inactivated microbial agents, conventional fertilization and blank control. The results showed that microbial agents significantly improved the biological characteristics of tomatoes, increased the fruit diameter and weight, enhanced the resistance to Fusarium wilt and bacterial wilt,increased the yield and economic benefits of tomatoes by 6.45% compared with conventional fertilization, and increased the yield of tomatoes by 44.67% compared with blank control.
