How to choose tomatoes? What are the methods of raising seedlings?

With the rising market price of tomatoes, the planting area of tomatoes is also expanding. Tomatoes like temperature and light. Too high or too low temperature will affect its growth and development. If farmers want to grow tomatoes with high yield, it is very important to select and raise seedlings. So how to choose tomatoes? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to choose tomatoes?

There are many varieties of tomatoes, there is no doubt that excellent varieties of tomatoes are an important prerequisite to ensure high quality and high yield. When selecting tomato varieties, we should pay attention to it, and we also need to combine the local actual planting conditions to select more suitable varieties. For example, in more arid areas, we should choose varieties with strong drought resistance and disease resistance. Only in this way can we improve the success rate of planting.

Second, what are the methods of raising tomatoes?

1. Seedbed

The time of raising seedlings determines the conditions of the seedbed. Nursery bed pay attention to warmth, enough light, slow heat dissipation are the requirements of raising seedlings in winter, such as greenhouse, small arch shed heating and so on. Raising seedlings is to be cool, avoid water, less light is the requirements of the summer seedling bed, while the seedling bed had better be aseptic, so as not to breed diseases and insect pests.

2. Seedling soil

Strong seedlings can reduce tomato fruit deformities, improve disease resistance, and achieve the purpose of increasing production. The seedling soil should have good air permeability, loose soil quality, nitrogen, phosphorus and potassium fertilizer and other trace elements. The average pH value of the soil is 6.5. Choose soil or wheat soil that has not grown eggplant crops for 2-3 years. The fertilizer mixed with soil should use mature farm manure that has been sterilized at high temperature to reduce the occurrence of germs. 10 jin of soil is mixed with 10 jin of farm manure, each accounting for 1/2 of the total. Every 200jin of nutritious soil can also add 20 jin of seaweed fertilizer and 20 jin of biological fertilizer. Seedling soil according to the planting area to convert on the line, every 667 square meters of land to 11.7 square meters of seedbed.

3. Seed treatment

Tomato seeds can only be sowed after four steps: seed selection, soaking, seed dressing and germination. Put the selected tomato seeds in a sterile container, soak them in warm water of 53 degrees for 5 hours, stir gently when the temperature is higher than 30 degrees, and then do not use them. Soak in trisodium phosphate with a concentration of 10% for 30 minutes after 5 hours. Soak the seeds into a wet cloth to accelerate germination, the temperature should be kept at 26 degrees, not more than 35 degrees. If possible, you can also wash the seeds with 25 degrees warm water every day. When the seed whitening reaches 80%, it is good to mix the seeds with seed dressing agent.

4. Seedling and sowing

Seedling sowing should be carried out on a sunny day, the seedbed should be watered thoroughly, and the height of the water above the seedbed is 0.05 meters, then sprinkle the fine soil on the surface of the seedbed and flatten it with a board. The seeds should be sealed immediately after sowing, and the temperature should be above 25 degrees during the seedling period, but not more than 30 degrees.

The above is the introduction of tomatoes. When planting tomatoes, many farmers will adopt the cultivation method of raising seedlings first and then transplanting them. Mid-late maturing seeds with heat resistance, disease resistance, storage and transportation resistance, high quality and high yield should be selected.
