Cultivation techniques of Tomato

Tomatoes are a vegetable that everyone is very familiar with. They are rich in nutrients and the market demand is very large. Now in the north and south of our country have a large cultivation area. When planting tomatoes, what we have to do is management work, and there are also many technical points, so how should tomatoes be cultivated? The following small series brings you the cultivation techniques of tomatoes. Let's take a look together!

1. Seed treatment

When the seeds are ready, soak them in clean water for an hour, then in hot water at 50 degrees Celsius for a quarter of an hour. When soaking seeds in hot water, stir constantly to ensure that the seeds are evenly heated, and then soak them in water for 3 hours. Remove it and soak it in trisodium phosphate for 20 minutes for disinfection. Then let the seeds fully absorb water and swell, put them at a temperature of 26-27 degrees, and keep them for about 3 days. In the germination process to maintain a stable temperature, moisture, etc. Often check the seeds, wash once a day, do the germination of seeds, germination fast and neat, can cultivate healthy seedlings.

2. Timely sowing

Tomato seeds are generally about 300 for one gram, about 25 grams per mu. According to the local climate environment, planting methods and other reasonable regulation of sowing time. For example, the sowing time in the area south of the Yangtze River is generally around July to August. Sowing methods are sowing, sowing, etc., no matter what sowing method, pay attention to covering a layer of fine soil after sowing. And to use carbendazim and other agents mixed with fine soil, enhance the disease resistance of tomato seedlings. In winter and spring, when the temperature is low, plastic film should be properly covered after sowing to improve the heat preservation ability of soil.

3. Temperature control

After tomato seed is sown, grow to seedling before the first true leaf, under suitable environment, general in a week or so. The temperature of seedling stage should be controlled at about 26-27 degrees, and the temperature at night should also be maintained at 14-16 degrees. The temperature at this time is very critical for the growth of seedlings, especially the soil temperature, which should be maintained at about 22 degrees. Then, with the change of weather and the growth of tomatoes, the temperature should be controlled well. If the temperature is not suitable, the impact on the growth of tomatoes will be very large, which will not only reduce the yield, but also the quality.

4. Scientific fertilization

In tomato growth period to do a good job topdressing work, control the proportion of nitrogen, phosphorus and potassium fertilizer. In particular, nitrogen fertilizer should not be applied excessively, but should be combined with phosphorus and potassium fertilizer. After tomato planting, when the seedlings slow down, topdressing fertilizer once, and then in the tomato first ear fruit began to expand when the second topdressing work can be started. If it is a mid-late maturing variety, then it should be applied twice or so. Then appropriate foliar fertilizer spraying, promote fruit ripening. Finally, control the amount of watering to avoid excessive moisture leading to excessive tomato growth and fruit drop phenomenon.

The above is a simple introduction to tomato cultivation techniques. The most important thing in tomato cultivation is to do a good job in management, improve yield and tomato quality, and expand planting benefits. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
