木霉复合菌剂对水稻生长发育及产量的影响

The Influence of Growth and Yield under Trichoderma Compound Microbial Agent on Rice

[目的]研究木霉复合菌剂对水稻生长发育及产量的调控作用,以及最佳使用量。[方法]以营口市农业科学研究所自主研发的木霉复合菌剂对水稻叶面进行喷施。[结果]1.5 L/hm2的木霉复合菌剂喷施叶面后显著提高了水稻的株高、分蘖数、冠层幅宽,使水稻光合叶面积增加,且有显著的增产效果,增产幅度达11%以上。[结论]该研究为大面积应用提供了科学的理论依据。

[Objective]Study the regulatory effect of Trichoderma compound microbial agents on rice growth,development,and yield,as well as the optimal dosage.[Method]Leaf spraying of rice using a Trichoderma composite microbial agent independently developed by Yingkou Agricultural Science Research Institute.[Result]The plant height,tiller number,canopy width and photosynthetic leaf area of rice were significantly increased by spraying 1.5 L/hm^(2) Trichoderma compound agent,and the yield was significantly increased by more than 11%.[Conclusion]This study provided a scientific theoretical basis for large-scale applications.
