| Abstract: | By using mid-mature Dianchao 2 as the material, the effect of cutting off its upper functional leaves and sheath leaf in its eary heading stage on its thousand-grain weight and setting rate was studied. The results showed: the sheath leaf had the greatest offect, the following were the second and the third leaves (from top to bottom). Cutting off the three upper leaves simultaneously affected the yield by 57%. That is to say the three upper leaves control the economic output of rice by 75%. |
