Embodiment 1
[0029] 1) Soak tomato seeds in warm water at 53°C for 13 minutes, then soak in 1% potassium permanganate solution for 14 minutes, rinse the soaked seeds with tap water repeatedly, and evenly spread the seeds on clean gauze , placed in a constant temperature box at 28°C for germination, and after 80% of the seeds germinated, they were raised on a solid substrate. The solid substrate was composed of peat, perlite, straw, sawdust and chemical fertilizers. Put them in a solid substrate and place them in a temperature-controlled greenhouse to grow. After the seedlings grow to 4 to 5 leaves, take out the seedlings from the solid substrate and transplant them in the field. listing period;
[0030] 2) When the seedling grows to 4 leaves, transplant the seedling to the field, apply enough basal fertilizer before transplanting, and apply iodine fertilizer in furrows, and the application amount of iodine fertilizer is controlled at 15mg / m 2 , so that the iodine content in the soil reach...
Embodiment 2
[0033] 1) Soak tomato seeds in warm water at 56°C for 16 minutes, then soak in 1% potassium permanganate solution for 16 minutes, rinse the soaked seeds with tap water repeatedly, and evenly spread the seeds on clean gauze , put it in a constant temperature box at 32°C for germination, and after 85% of the seeds germinate, grow seedlings in a seedbed. The method of seedling cultivation in a seedbed is: sow the seeds after germination on a greenhouse seedbed, and transplant the seedlings after they grow to 4 to 5 leaves. This method is suitable for the cultivation of large-scale seedlings, but the seedlings may not be as robust as those grown on solid substrates;
[0034] 2) When the seedlings grow to 5 leaves, transplant the seedlings to the field, apply enough basal fertilizer before transplanting, and apply iodine fertilizer in furrows, and the application rate of iodine fertilizer is controlled at 150mg / m 2 , so that the iodine content in the soil reaches 150mg / kg, topdress...
Embodiment 3
[0037]1) First soak the tomato seeds in warm water at 55°C for 14 minutes, then soak them in 1% potassium permanganate solution for 15 minutes, rinse the soaked seeds with tap water repeatedly, and spread the seeds evenly on clean gauze Put it in a constant temperature box at 30°C to accelerate germination, and after 82% of the seeds germinate, grow seedlings on a solid substrate or a seedbed;
[0038] 2) When the seedling grows to 5 leaves, transplant the seedling to the field, apply enough basal fertilizer before transplanting, and apply iodine-containing organic fertilizer in furrows, and the application rate of iodine-containing organic fertilizer is 35 mg / m 2 , so that the iodine content in the soil reaches 50mg / kg, topdressing with compound fertilizer twice during the tomato growth period, the iodine content in the ripe tomato reaches 1100ug / kg;
[0039] 3) The above-mentioned tomatoes with an iodine content of 1100ug / kg are subjected to aseptic filling after the product...
