- Abstract:
- Seed of Chinese cabbage were dressed with four different seed coating agents.After planting，the emergence rate of seedlings and growth index from both pot and field experiment were recorded and calculated，then the effect analysis of different seed coating agents on plant rhizosphere soil micro-ecology environment was carried out.The results showed that the emergence of seedling was affected significantly when seeds were treated by different seed coating agents，among which，seedling emergence power and seedling emergence rate of Carbosulfan，Thiram-Carbosulfan and Carbosulfan-Triadimenol-Thiram treatments were decreased significantly.Seedling emergence power of Carbosulfan (61.2%)，Thiram-Carbosulfan (65.3%) and Carbosulfan-Triadimenol-Thiram (63.5%) reduced by 28.2%，23.4% and 25.5% compared with the control respectively，meanwhile，seedling emergence rate of 64.1%，75.3% and 72.4% of treatments mentioned above reduced by 26.4%，13.5% and 16.9%，respectively.The investigation reasults based on growth index of cabbage seedling suggested that all seed coating agents affected the seedling growth of plant.The greatest measures of effect were Thiram-Carbosulfan and Carbosulfan-Triadimenol-Thiram，and fresh weight of above-ground part was average of 1.32 g and 1.36 g for each individual plant，and reduced by 64.0% and 62.9% compared with the control respectively.Fresh weight of underground part was 0.11 g and 0.09 g per plant，reduced by 57.7% and 65.4%,respectively.Root activity of cabbage seedling was also affected by each of seed coating agent with a reduction by 14.8%-29.6%，whereas growth of plant in field appeared to be no influence after transplanting.Rhizosphere soil enzymatic activity of cabbage in seedling stage reduced significantly，in Carbosulfan treatment，activity of the urease，phosphatase and sucrase from soil around root of cabbage seedling displayed the significant reduction(47.04，62.40,1.90 mg·mL·g-1，respectively)，showing the greatest reduction by 46.3%，17.7% and 37.9%.However，significant effect on rhizosphere soil enzymatics activity was not found in the field treatment after transplanting.In addition，population quanity of rhizophere soil microorganism seemed to be changed after seed dressing treatment，for instance，the numbers of soil bacteria and actinomyces were decreased and fungi showed a contrary tendency.
