Latest Technical Method Tutorial for Raising Early Spring Tomato Seedlings

Now, with the development of the vegetable planting industry, the planting area of various vegetables is also growing larger and larger. Tomato is naturally no exception, and now more and more people are growing tomatoes. As a result, the pressure of competition is also growing, and if you want to improve your own competitiveness, then raising fully strong seedlings is very critical. Therefore, the work of raising seedlings in early spring is something we cannot ignore. So below, the editor has brought you the early spring tomato seedling raising technology. Let's take a look!

1. Seed treatment

Before raising tomato seedlings in early spring, we must first treat the tomato seeds. Do a good job of disinfecting and sprouting the seeds, etc., to prevent the seeds from carrying pathogens, and do a good job of preventing diseases such as leaf mold and canker. First, the seeds should be scalded in warm water. First put the seeds in hot water at about 55 degrees, and during the soaking process, be careful to stir continuously for a quarter of an hour. Then put them in hot water at about 30 degrees and soak for 3 hours before removing them. Then wrap them in a wet cloth and place them at a temperature of about 30 degrees for sprouting. In addition, we can also use agents such as trisodium phosphate for seed soaking and disinfection.

2. Seedbed preparation

After preparing the seeds, it is time to prepare the seedbed well. Before sowing the seeds, first water the seedbed thoroughly, and then spray the seedbed with agents such as Previcur. Carbendazim and other agents can also be used for disinfection. When spraying carbendazim, it should be mixed with water. After spraying, cover it with plastic film for a period of time, and after about 3 days the pathogens in the soil can be eliminated. Then be careful to apply sufficient base fertilizer. After the base fertilizer is sufficient, no additional fertilizing is needed during the tomato seedling stage.

After the tomato seedlings emerge and all seedlings are up, temperature control in the seedbed is very important. The temperature must not be too high, so as to ensure healthy seedling growth and enhance the cold resistance of the seedlings. Then when the seedlings grow two leaves and one heart, good heat preservation work should be done. If the temperature is too low, then it will affect flower bud differentiation, causing serious flower and fruit drop and leading to reduced yield. During the seedling stage, generally no watering is needed. If the soil is too dry, then it should also be done at noon on a sunny day. Do not water with cold water, and the amount of watering should not be too large, to avoid water accumulation and root rot. An appropriate amount of plant ash can be scattered on the seedbed to absorb moisture.

4. Daily management

When planting tomatoes in early spring, we should pay attention to controlling light well. If the seedlings encounter continuous rainy weather and insufficient natural light during the growth stage, then the tomato seedlings will have their normal growth affected because they are in a dark and weak-light environment for many days. Because if light is insufficient, tomatoes cannot carry out photosynthesis, resulting in reduced accumulation of nutrients and causing malnutrition in tomatoes. Therefore, attention should be paid to appropriately increasing light intensity. On cloudy days, the straw curtains should also be normally uncovered and covered to ensure normal tomato growth. In addition, we should also do a good job in pest and disease control to ensure yield and avoid some unnecessary losses.

The above is a brief introduction to early spring tomato seedling raising technology. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
