Embodiment 1
[0017] The green pollution-free cultivation method of tomato comprises the following steps:
[0018] (1) Preparation before sowing: Select tomato varieties that are resistant to low light, low temperature and freezing damage, cold resistance, excellent disease resistance, large production potential, and good commercial performance, and spray with 30m1 of formalin solution and 3kg of water per acre of seedbed. Finally, cover the film, soak the seeds in 0.1% potassium permanganate solution for 30 minutes, remove and wash, put in warm water at 50°C and stir for half an hour, when the water temperature drops to 30°C, soak for 4 hours, then transfer to cold water for soaking 12 hours;
[0019] (2) Sowing and raising seedlings: selection is 5:3:2 by mass ratio without the farmland soil of disease and insect pest, fully decomposed organic fertilizer and plant ash to prepare nutritious soil, the seed that germinates is evenly sown in the seedbed, every acre sows 30g of seed, in Cover...
