| 摘 要： | 采用复合微生态制剂(VT菌)对棉花进行浸种处理及灌根、喷施,观察不同生长发育阶段及其对棉花生长及抗病性的影响。结果表明,复合微生态制剂(VT菌)在棉花播种前浸种可以有效防止棉花苗期病害的发生,促进棉苗生长,增强棉苗抗逆性。用一定浓度的复合微生态制剂(VT菌)浸种,结合在棉花黄萎病发病高峰前期喷施或灌根处理,可防止棉花黄萎病的发生,提高棉花产量,施用复合微生态制剂(VT菌)的处理比对照最高增产16.8%。

| Abstract: | Through dipping cotton seedling's roots and seed soaking with complex probiotics(VT),the authors observed the influence on cotton growth and its anti-virus during the different phases of cotton history.The results showed that soaking seed with VT before sowing may effectively prohibit virus,promote cotton growth and increase its resistance.Soaking seed with certain concentration of complex probiotics(VT) or spraying and watering roots with VT before occurring of verticillium wilt may prevent the virus and give more yield than the contrast by 16.8%. |
