The latest course of Tomato cultivation techniques and methods

Tomato is a kind of vegetable that everyone is very familiar with, which is rich in nutrition and the market demand is very large. Now there is a large cultivation area in the north and south of our country. When growing tomatoes, what we need to do well is the management work, and there are also many technical points, so how to cultivate tomatoes? The following editor brings you the cultivation techniques of tomatoes, let's have a look!

1. Seed treatment

After the seeds are ready, soak them in clean water for an hour, then soak them in 50 degrees hot water for a quarter of an hour. When soaking the seeds in hot water, keep stirring to ensure that the seeds are heated evenly, and then soak them in clean water for 3 hours. After being removed, it was soaked in trisodium phosphate for 20 minutes for disinfection. Then let the seeds fully absorb water and sprout at a temperature of 26-27 degrees Celsius for about 3 days. Maintain a stable temperature, moisture and so on in the process of sprouting. Often check the flipped seeds and wash them once a day. The seeds that have done the work of accelerating germination can emerge quickly and neatly, and can cultivate strong seedlings.

2. Sowing seeds at the right time

Tomato seeds are generally about 300 seeds per gram, sowing about 25 grams per mu. According to the local climate, planting methods and other reasonable control of sowing time. For example, the sowing time in the area south of the Yangtze River is usually around July-August. Sowing methods include sowing, on-demand and so on. No matter what sowing method is, we should pay attention to covering a layer of fine soil after sowing. And carbendazim and other agents should be mixed with fine soil to enhance the disease resistance of tomato seedlings. In winter and spring and other low temperature seasons, it is necessary to properly cover plastic film after sowing to improve the heat preservation capacity of the soil.

3. Temperature control

After the tomato seed is sown, it is usually about a week before the seedlings grow the first true leaf in a suitable environment. The temperature in the seedling stage should be controlled at about 26-27 degrees, and the temperature at night should be kept at 14-16 degrees. The temperature at this time is very critical to the growth of seedlings, especially the soil temperature, which should be kept at about 22 degrees. Then it is necessary to control the temperature with the change of the weather and the growth of tomatoes. If the temperature is uncomfortable, it will have a great impact on the growth of tomatoes, which will not only reduce the yield but also the quality.

4. Scientific fertilization

It is necessary to do a good job of topdressing and control the proportion of nitrogen, phosphorus and potassium during the growing period of tomatoes. In particular, nitrogen fertilizer should not be applied, and it should be combined with phosphorus and potassium fertilizer. When the seedlings of tomatoes are slow after planting, a seedling-promoting fertilizer is applied once, and then the second topdressing work can be started when the first ear of the tomato begins to expand. If it is a mid-and late-maturing variety, it should be applied twice more. Then properly spray foliar fertilizer to promote fruit ripening. Finally, the amount of water should be controlled to avoid the phenomenon of falling flowers and fruits caused by too much water.

The above is a brief introduction to tomato cultivation techniques. The most important thing in tomato cultivation is to do a good job of management and improve the yield and quality of tomatoes in order to expand the planting efficiency. That's all for today's introduction. This article is for reference only. I hope it can help you all.
