Seedling raising techniques of Tomato in early Spring

Now with the development of vegetable planting industry, the planting area of all kinds of vegetables is getting larger and larger. Of course, tomatoes are no exception, and now more and more people grow tomatoes. Therefore, the pressure of competition is also increasing, and if you want to improve your competitiveness, then a comprehensive strong seedling is very critical. Therefore, we can not ignore the work of raising seedlings in early spring. So the editor below brings you the early spring tomato seedling raising technology, let's have a look!

1. Seed treatment

Before raising tomato seedlings in early spring, we should first deal with tomato seeds. Do a good job of seed disinfection and germination, avoid seeds carrying germs, and do a good job in the prevention of leaf mold, canker and other diseases. First of all, we should blanch the seeds in warm water, first put the seeds in hot water of about 55 degrees, and pay attention to stirring continuously for a quarter of an hour in the process of soaking. Then soak it in hot water about 30 degrees for 3 hours and fish it out. Then wrap it in a wet cloth and put it at a temperature of about 30 degrees to sprout. In addition, we can also use trisodium phosphate and other agents for seed soaking and disinfection.

2. Seedbed preparation

Once the seeds are ready, the seedbed should be ready. Before sowing the seeds, first pour water into the seedbed, and then make Pricket and other chemicals spray on the seedbed. Carbendazim and other agents can also be used for disinfection. When spraying carbendazim, it should be mixed with water. After spraying, it should be covered with plastic film for a period of time. The germs in the soil can be eliminated in about 3 days. Then we should pay attention to the application of sufficient base fertilizer, after the base fertilizer is sufficient, there is no need to topdressing in the tomato seedling stage.

3. Temperature and humidity control

After tomato seedlings are unearthed, the temperature control of the seedling bed is very important. The temperature should not be too high to ensure the robust growth of seedlings and enhance the cold resistance of seedlings. Then when the seedlings grow two leaves with one heart, it is necessary to do a good job of heat preservation. If the temperature is too low, it will affect the flower bud differentiation, there will be a serious phenomenon of falling flowers and fruits, resulting in a decline in yield. In the seedling stage, generally do not need watering, if the soil is too dry, then it should also be carried out at noon on a sunny day, do not pour cold water, and the amount of water should not be too large to avoid causing stagnant water and rotten roots. an appropriate amount of plant ash can be sprinkled on the seedbed to absorb moisture.

4. Daily management

When planting tomatoes in early spring, we should pay attention to controlling the light. If the seedlings in the growth stage, encounter continuous rainy weather and lack of natural light. Then tomato seedlings will affect their normal growth because they are exposed to dark and weak light for many days. Because of the lack of light, the tomato can not carry out photosynthesis, resulting in a decline in the accumulation of nutrients, resulting in tomato malnutrition. Therefore, we should pay attention to properly improve the light intensity, and uncover the grass curtain normally in cloudy days to ensure the normal growth of tomatoes. In addition, we should also do a good job in the prevention and control of diseases and insect pests to ensure output and avoid some unnecessary losses.

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