Appropriate treatment of tomato seeds before sowing can reduce tomato seed colonization, promote seed vigor, promote seedling neatness, and enhance seedling resistance.
Tomato seed processing
1, warm soup soaking
Warm soaking is a useful way to break the seed dormancy, promote seed germination, sterilization, disease prevention, and enhance seed resistance. The specific approach is:
1 Soak the seeds with water for 1-2 hours.
2 Remove the seed and put it in warm water of 55 degrees Celsius. Keep the water temperature soaked for 15 minutes. Continue immersing the seed for 3-4 hours before germination. When soaking the seed, it is usually a seed and two water. Together, it should be continuously and rapidly mixed to make the seeds evenly heated to prevent scalding.
3 To continue heating water, adhere to the water temperature of 55 degrees Celsius. This disinfection method can prevent the onset of tomato leaf disease, canker disease, early blight and other diseases.
2, pharmacy disinfection
1) soaking with trisodium phosphate: soaking with fresh water for 3-4 hours, removing and draining, then soaking in 10% trisodium phosphate solution for 20 minutes, washing with water and germination. This approach has a more significant role in tomato virus disease.
2 formalin solution soaking: the pre-impregnated seeds are soaked in a 1% solution of formalin for 15-20 minutes, the container should be sealed when soaking to avoid volatile liquid, then removed and put up with a damp cloth After boring for 2-3 hours in a closed container, it is rinsed and rinsed clean with fresh water, followed by soaking and germination. This method can reduce or control the onset of tomato early blight.
3 Soaking seeds for 15-30 minutes with 0.1% potassium permanganate solution can effectively reduce the onset of tomato mosaic virus disease and early blight.
4 Pre-soaked tomato seeds were soaked in a streptomycin solution of 1000 mg/kg for 30 minutes for better control of bacterial wilt.
