Seed processing method
According to the survey and related data, the diseases occurring during the growth of vegetables are mostly caused by the seeds with pathogenic bacteria. Therefore, disinfection of vegetable seeds before sowing is necessary, which can effectively reduce the occurrence of diseases during crop growth. Several methods of seed treatment are introduced as follows: 1. Soaking with warm soup: soaking in warm water at 50-55°C for 10-15 minutes. 2. Disinfection of pharmaceuticals: (1) Soaking seeds with 10% trisodium phosphate for 20 minutes can prevent the occurrence of angular spots in melons and solanes. (2) Soaking seeds with 40% formalin 150 times for 1.5 hours prevents melon angular lesions. (3) Soaking seeds with 0.1% potassium permanganate for 15-30 minutes can effectively prevent diseases such as eggplant, melon vegetables virus disease, wilt disease and damping-off. (4) Soaking seeds with thiophanate-methyl 1000-fold solution or zein-zinc 1500-fold solution for 10-15 minutes can prevent seedling stage blight and damping-off from melon and eggplant vegetables. (5) Soaking seeds with 40% formaldehyde for 30 minutes can prevent the occurrence of melon bacterial blight. The above 1-2 agents can be used to disinfect the seed, pay attention to the leachate after soaking, and rinse with water several times.
