| Abstract: | Experimental results showed that the all treatments have the promoting effects in the wheat take all decline with different nutrient substances in the field of disease severity, and the effectiveness of the treatments with phosphoric fertilizer was higher than that of other treatments among the all treatments tested. By the analyses of fuzzy decision, the treatment N P K organic fertilizer was the best scheme for the take all control in all treatments tested, and its disease control efficency and percentage of yield increase were 84.1% and 66.1% respectively compared with those of control. |
