Rapid Seedling raising technique of Tomato

Tomato is a kind of vegetable that we see more in our life, and it has a very large planting area in our country. When planting tomatoes, we should do a good job in management to ensure the normal growth of tomatoes and increase yield. Before planting, what is closely related to tomato yield is the work of raising seedlings. So how to grow tomato seedlings quickly? The following editor will give you a brief introduction, let's have a look!

1. Preparatory work

Generally speaking, tomato seedling raising is mainly based on hole plate, and the quantity and specification of hole plate should be controlled according to the number of seedlings. Then the seedling substrate should be prepared and prepared with peat and vermiculite, and the proportion should be controlled at about 2:1. After preparing the substrate, we also need to do a good job of applying base fertilizer, which is mainly compound fertilizer, and 2.5kg compound fertilizer is applied per cubic meter. The fertilizer is fully mixed with the matrix to improve the fertility of the matrix. Before sowing, attention should be paid to the comprehensive and thorough disinfection of the seedbed to reduce the number of bacteria and avoid affecting the growth of tomatoes.

2. Deal with the seeds

Tomato seeds should be soaked and sterilized before sowing. First of all, soak the seeds in warm water of about 52 degrees 20min. Then soak the seeds in water of about 25 degrees for 4 hours to promote germination. And also need to soak the seeds with trisodium phosphate and other solutions for 20 minutes, after soaking the seeds, remove the seeds, and then clean the remaining potions on the seeds. Then sow, when sowing, we should pay attention to control the depth, the depth should not exceed 1 cm. Because it is a pot seedling, so the seeds can be sown in the sowing hole.

3. Temperature management

In the seed germination, we should pay attention to maintain the temperature, the indoor temperature is kept at about 26 degrees, generally three days or so can emerge. After more than 65% of the seedlings have emerged in the burrow tray, the seedlings can be placed in the greenhouse. The temperature in the greenhouse should be controlled at about 25 degrees during the day and 17 degrees at night. If the temperature is too low at night, it is also necessary to take warm measures such as heating the hot line. Avoid reducing the speed of seedling emergence and causing diseases such as quenching disease.

4. Seedling stage management

After sowing, we should water thoroughly once to keep sufficient water content in the seedling substrate. When the seedlings grow two true leaves and one heart leaf, the water content of the substrate should be kept at about 68%. Then the water content of the substrate was reduced by about 5% before seedling formation. Then after the first true leaf of the seedling grows, it is necessary to do a good job of replenishing the seedlings, and if there is a lack of holes, the seedlings with the same growth should be made up in time. To ensure the whole seedling rate, and then to do a good job in the prevention and control of diseases and insect pests, such as quenching disease, virus disease and aphids, to promote the healthy growth of seedlings.

The above is a brief introduction to the work of rapid breeding of tomato seedlings. Tomato seedling raising is very important to the quality and yield of tomato, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
