Abstract

The effects of nitrogen,potassium and silicon fertilizer on growth and resistance of rice seedlings against rice blast disease were studied.The experimental design(i.e.,3 fertilizers5 dosage levels3 rice varieties) applied with artificial inoculation of Magnaporthe grisea in greenhouse.The results showed that the leaf length and width of Teyou 627(R),DQibaoyou 527(MR) and Xianyou 63(MS) were improved by application of nitrogen and potassium fertilizer.There was a significant relationship between nitrogen application and rice seedling's blast disease index on Teyou 627,DQibaoyou 527 and Xianyou 63.A significant negative relationship between disease index on Xianyou 63(MS) and potassium or silicon fertilizer.A significant correlation existed between leaf width and disease index on 3 rice varieties.They increased with the increase of nitrogen fertilizer,but decreased with the increase of potassium or silicon fertilizer.
