Rehe province agricultural experiment field In 1952 wheat, millet, sorghum after the pathogen inoculation, the seeds were inoculated: the spring wheat (Xiao Hongmang) were treated with 0.1% Triticum sp. On the surface of the seed; scattered spore pathogen natural inoculation method. Millet (No.522) Seed the surface of the seed with 0.1% C. albicans; the millet (Paeonia lactiflora) is applied to the surface of the seed with 0.1% of the disease. Sorghum (Shuangliao dwarf) Apply 0.1% silkworm spores to the seed surface. The inoculated seeds were dried in the room and on the ground, respectively, from 8 am to 5 pm a total of 9 hours sun, the sun sucked in the daytime during the day indoors, the rainy days, the windy day is not the sun. Wheat drying dates from July 15 to September 8; millet, sorghum basal dates from October 4 - 29.
