| Abstract: | The seeds of wheat were presoaked in an earthworm biological preparation prior to sowing. 0. 8 % appeared to be the optimum concentration for seed treatment. It increased photosynthesis ability of the plants by 36. 5 and 24. 7% at the seedling stage and booting stage, respectively, and raised N uptake by 35. 29 and 16. 61%. The transportation of photosynthated to the seeds was promoted at later stages. The absorption of fertilizer P and soil P by the plants was emhanced by 26. 7 and 21. 9% , respectively, at the seedling stage and harvest stage. The economic yield of the treatment was 14. 95% more than the control. |
