The Latest Techniques and Methods for Fast Tomato Seedling Raising: A Tutorial
Tomato is one of the vegetables we see fairly often in our daily lives, and it has a very large planting area in our country. When growing tomatoes, we need to do a good job with management to ensure normal tomato growth and increase yields. Before planting, what is most closely tied to tomato yield is the seedling raising work. So how do you raise tomato seedlings quickly when growing tomatoes? Below, the editor will give you a brief introduction. Let's take a look together!
1. Preparation work
Tomato seedling raising is generally based on plug tray seedling raising, and the number and specifications of the plug trays should be controlled according to the number of seedlings. Then the seedling substrate should be prepared, using peat, vermiculite, and so on, with the ratio controlled at about 2:1. After preparing the substrate, we also need to do a good job with base fertilizer application. The base fertilizer is mainly compound fertilizer, applied at 2.5 kg per cubic meter. Mix the fertilizer and substrate thoroughly to improve the fertility of the substrate. Before sowing, pay attention to carrying out a comprehensive and thorough disinfection of the seedbed to reduce the number of bacteria and avoid affecting tomato growth.
2. Treating the seeds
Before sowing tomato seeds, the seeds should be treated by soaking to promote germination and disinfection. First, soak the seeds in warm water at about 52 degrees for about 20 min. Then place the seeds in water at about 25 degrees and soak for 4 hours to promote germination. It is also necessary to soak the seeds in a solution such as trisodium phosphate for 20 minutes. After soaking with the chemical agent, remove the seeds and then wash them clean of the residual solution on the seeds. Then sow. When sowing, pay attention to controlling the depth; the depth must not exceed 1 cm. Because this is plug tray seedling raising, simply sow the seeds into the sowing holes.
3. Temperature management
When promoting seed germination, pay attention to maintaining the temperature. Keep the indoor temperature at about 26 degrees, and seedlings will generally emerge in about three days. After more than 65% of the seedlings in the plug trays have emerged, the seedlings can be placed into the greenhouse. The daytime temperature in the greenhouse should be controlled at about 25 degrees, and the nighttime temperature should also be kept at about 17 degrees. If the nighttime temperature is too low, then warming measures such as heating with ground heating wires should also be taken. Avoid slowing seedling emergence and causing diseases such as damping-off.

After sowing, we should water thoroughly once to keep the seedling substrate sufficiently moist. When the seedlings grow two true leaves and one heart leaf, the substrate moisture content should be kept at about 68%. Then before the seedlings become established, lower the substrate moisture content by about another 5%. Then, after the first true leaf of the seedlings grows out, do a good job with filling in missing seedlings. If there are empty holes, promptly fill them with seedlings of the same growth. Ensure a full stand of seedlings, and then also do a good job with pest and disease control, such as damping-off, viral disease, and aphids, to promote healthy seedling growth.
The above is a brief introduction to fast tomato seedling raising. Tomato seedling raising is very important for both the quality and yield of tomatoes, so everyone must pay close attention to it. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
