| Abstract: | This experiment was about the effect of the new mixed agent to prevent the boll-rot of cotton that was carried out on the Yangtze University in 2004.The result showed that the new mixed agent developed by plant disease laboratory of Yangtze University could prevent boll-rot of cotton and increase the yield of cotton.The treatment of using the agent could decrease the boll-rot 13% and increase the yield 16% than CK.The multi-factors test also showed that the new mixed agent combining the reasonable cultivation measure was more advantageous to its effect.With the density of 15000 plants each hectare and the nitrogen fertilizer of 450 kg each hectare,the effect of the new mixed agent to prevent boll-rot of cotton is the best. |
