Key points of soilless cultivation techniques of Tomato

As a common vegetable in our country, tomato has a very large planting area in our country. Now the development of science and technology in our country is becoming more and more mature, and now there are many planting patterns of tomato. Soilless cultivation is one of them, so how to do soilless cultivation tomato? Today, the editor brings you the key points of soilless cultivation of tomatoes. Let's take a look at them.

1. Seedling planting

Before soilless cultivation, you should first deal with the seeds and soak them in warm water of about 60 degrees for about 20 minutes. Then soak in trisodium phosphate for 25 minutes, put in normal temperature water for about six hours, can effectively eliminate the virus. Then put the seeds evenly in the moisture can not kill, cover a layer of wet cloth, put in the environment of about 30 degrees. The seeds and gauze should be washed twice a day to accelerate germination. Under normal circumstances, it can be germinated in about 3 days, and then sown after germination. Before sowing, the nutrient solution should be watered thoroughly with the Japanese Yamazaki tomato formula, and then the seeds should be sowed on demand and then covered with a layer of disinfection substrate.

2. Seedling stage management

In the early stage of seedling cultivation, the seedling bed should maintain a water layer of about one centimeter. After the cotyledons of the seedlings were fully expanded, the nutrient solution was applied to the seedling bed. Prepare the standard nutrient solution according to the professional formula. Attention should be paid to keeping the seedlings at a relatively high temperature before emergence. After emergence, the temperature is reduced to about 20 degrees, and the temperature is about 12 degrees at night. Humidity should not be too high to prevent diseases, and then one or two doses of Japanese Yamazaki tomato formula should be reasonably sprayed according to seedling growth, substrate and weather to provide adequate nutrition for seedling growth.

3. Planting management

When the seedlings reach the age of one month, grow 3 leaves, the plant height is about 12 cm, and there is no excessive growth, the phenomenon of diseases and insect pests can be planted. Seedling planting should be carried out when the temperature is not high in the afternoon. The distance between plants should be controlled at about 30 cm, and the seedlings should be properly separated to facilitate management. Attention should be paid to pouring the nutrient solution once after planting, and ventilation can not be carried out before slowing down the seedlings after planting. The temperature should be kept at about 30 degrees, and the maximum should not exceed 35 degrees. Then the humidity should be controlled at about 75%, not too high, keep suitable sunlight, and pay attention to shading when the light is too strong.

4. Plant management

When planting, we also have to do a good job of hanging vines of tomato plants, pull a piece of iron wire above the plant, and then hang the plant on the wire with a rope. The main method of pruning is single-stem pruning, because the ability of lateral branches of tomato is relatively strong, so we should pay attention to erase the lateral buds in time to avoid consuming too much nutrition. Then as the plant grows, the plant is wound around the rope, usually once every 7 days or so. We should also do a good job of thinning flowers and fruits, keep about 4 fruits per panicle for medium fruit type, remove redundant flowers and fruits with abnormal growth, and concentrate nutrients. Then it is necessary to remove the yellow leaves of the old disease in time, and when the plant grows to the wire, it can fall off the vine.

The above is a brief introduction of tomato soilless cultivation techniques. That's all for today's introduction. This article is for reference only. I hope it can help you all.
