Choosing a field with deep, loose, breathable and fertile soil to plant tomatoes, deep ploughing and proper addition of base fertilizer can improve soil fertility. Select the appropriate seeds according to the growth requirements and planting location. And pay attention to eliminate withered and broken seeds. To accelerate germination before sowing, chemical agents can be used for soaking, and the sowing time is generally around 10- 15 cm. After sowing, cover with a thin layer of soil, and then cover with plastic film.
First, the whole process of tomato planting technology
1. Choose a field with deep soil layer, loose air permeability and fertile soil for planting. Deep ploughing and soil preparation before planting can reduce pests and diseases by allowing sunlight to shine on the soil. Appropriate addition of base fertilizer to soil can improve soil fertility.
There are many varieties of tomatoes. You can choose suitable seeds according to the growth requirements and planting location, or you can go directly to the seed shop to buy seeds. Carefully remove withered and broken seeds.
3. Germination should be accelerated before sowing and seedling raising, which can break the dormancy state of seeds. Seeds can be soaked in hot water and stirred, or soaked with chemicals, which can kill germs on the surface of seeds and prevent seedlings from being affected by germs.
4. Pay attention to the spacing when sowing, and try to control it around 10- 15cm, otherwise it will affect the growth of seedlings. After sowing, cover with a thin layer of soil, and then cover with plastic film to keep warm.
5. After planting for about 3-5 days, the seeds will begin to germinate. At this time, you can peel off the film and let it grow healthily in a ventilated environment. Note that after the seeds grow into seedlings, the demand for nutrients increases, and proper amount of manure should be sprayed to supplement nutrients to make them grow vigorously.
Second, tomato management methods
1. You can't just apply some kind of fertilizer to tomatoes. Nitrogen, phosphorus and potassium compound fertilizer should be used as far as possible for irrigation, green seedling fertilizer should be used after customized seedling delay, and calcium phosphate and potassium dihydrogen phosphate solution should be used for irrigation during peanut filling period.
2. In the process of planting, the growth temperature is controlled between 22-28℃, so that the tomato grows rapidly and the juice is more abundant. It is necessary to stabilize the soil at the seedling stage. If the temperature is 22-23℃, the seedlings will drop if the temperature is too high.
3. Green ripening, discoloration, ripening and full ripening are the four stages of tomato. In the fully mature stage, all tomatoes should be harvested as soon as possible to avoid rot and damage caused by hanging on the branches for a long time, thus attracting germs and pests.
4. Tomatoes should be pruned in time when they are planted, and they will be interrupted and pinched after the stems and leaves grow. When lateral buds grow at the base of the stem, they should be cut off as soon as possible to prevent the invasion of pests and diseases. When the flower grows, cut off other lateral branches, and cut off the main head after fruiting to avoid overgrowth.
