2.1 The effect of organic manure and chemical fertilizer on vegetative growth traits
Table 1 shows the character of vegetative growth in organic manure cult ivation and chemical fert ilizer
cultivation condition. Comparing the data in the table it can be seen, there is significant low in the plant
height, stem d iameter and the dry weight in organic manure cultivation at the early growth stage, But as the
growth processing, the stem d iameter, stem length and the dry weight of the above-ground part has exceeded
chemical fertilizer cultivation in 80 days after transplanting compared with the chemical fertilizer cultivation,
although the seedling growth was lower at the early stage. The result shows the restricting factors of the Stevia
