通过对小麦条锈病潜育期与温度关系的研究 ,得出了直线方程 y=4 8.9- 2 .3x,即日平均气温在5～ 17℃ ,日平均气温每升高 1℃ ,潜育期缩短 2 .3d。用接种喷药法对粉锈宁药理进行研究 ,结果 ,粉锈宁防治小麦条锈病显效期为 10～ 15d,有效期为 5～ 7d;温度偏低则显效期和有效期偏长 ,温度偏高则显效期和有效期偏短。最佳防治期的起始防治标准以有中心病团出现为准 ,第 2次用药与第 1次用药相隔 4 0 d左右 ,第 3次用药与第 2次用药相隔 30～ 35d
By studying the relationship between the temperature and the incubation period of wheat stripe rust, the linear equation y = 4 8.9-2.3x is obtained, that is, the average daily temperature is between 5 and 17 ℃, and the daily incubation period is shortened 2 .3d. Inoculation spraying method for the study of triadimefon pharmacological results, the results of triadimefon wheat stripe rust control effective period of 10 ~ 15d, valid for 5 ~ 7d; low temperature, the effective period and the effective period of long, high temperature, the effective period and expiration Shorter. The best prevention and treatment of the initial prevention and treatment criteria to have the center of the disease group shall prevail, the second medication and the first medication separated about 40d, the third medication and the second medication separated by 30 ~ 35d
