With the development of agriculture, many people planted tomatoes to choose soilless cultivation techniques. It is not a new technology to plant tomatoes in the air, but some people still engage in this technology or a “outsiderâ€.
So, how do you grow a soilless tomato?
1, nursery
First, you need a solar greenhouse, and then equipped with nutrient solution pool, water pump, piping system, solenoid valve, automatic control system and other cultivation facilities.
Then start seedlings, generally tomato seedlings in two seasons, respectively, in mid-August and mid-late November. Seeds before seedlings should be sterilized with silver, then soaked for 30 minutes. After soaking seeds, the seeds are placed in an artificial intelligence climate box at 20-29 °C for germination. After germination, the germinated seeds are sown in vermiculite, and appropriate nutrient solution is provided under suitable conditions. If natural light is insufficient, artificial light can be appropriately increased, and sufficient supply of boron elements is ensured at the seedling stage.
When the seedling grows to 3-5 cm, it is planted in a nutrient bowl to promote its growth. When the seedling grows to 10-20 cm, the seedlings are manually planted in the cultivation trough, and the planting density is about 2800 plants per 667 square meters.
2, hanging vines
After the tomato flowering result, the plant is supported by the plastic rope hanging method. The pruning method adopts the method of single-stalk pruning, that is, the upper end of the rope is hung on the wire above the greenhouse, and the lower end is attached to the stem of the base of the tomato plant to allow the plant to grow upward. Wrap the rope around the plant.
3, thin fruit
Remove the dysplastic malformed fruit and some small fruits, generally medium-sized fruits, with four fruits in the first ear; three fruits in the first ear of the fruit-shaped fruit, and the same results in the second and third ears. many.
4, picking leaves
The old leaves that have shrunk and yellowed and the leaves under the fruit that have already been harvested are removed in time, and the old leaves that have been removed should be placed in a special collection bag and brought out to the greenhouse for treatment to prevent the spread of pests and diseases.
5, the tip
In order to facilitate the early maturity of the fruit and pull on time, and does not affect the preparation of the mechanism of the posterior iliac crest, the tip treatment is generally selected. The tip of the scorpion is divided into two sputum. The spring sorghum is selected in mid-May. Generally, the fruit is 8-10 ears and the apex is selected. The autumn sorghum is selected after October, and the fruit is generally 6-7 ears.
6, pollination
16 °C at night is the optimal temperature for tomato pollen germination. During the daytime, the temperature is above 20 °C, especially when it is sunny, the pollen can be scattered in large quantities. When the tomato is pollinated, it can be sprayed with a small sprayer. The pollination should be selected on a sunny day. After pollination, the management of fertilizer and water should be strengthened to promote early maturity and high yield.
7, harvesting
The soilless cultivation tomato planting project is not subject to seasonal restrictions. It can be cultivated in areas with greenhouse conditions, and it can also develop ecological tourism and tourism. It is a planting project that cannot be underestimated.
Soilless cultivation of tomatoes, until the harvest season, a red fruit hanging on the vines, as if hanging in the air, very ornamental value. Not only can you sell fruit, but you can also develop an ecological sightseeing park. The prospects are not very optimistic.
Recommendations for selecting anti-aging raw materials:
1. Antioxidant performance: Anti-aging cosmetic ingredients should have good antioxidant performance, which can effectively resist free radicals and protect skin cells from oxidative damage.2. Repair function: Anti-aging cosmetic ingredients should have repair function, which can promote the regeneration and repair of skin cells and reduce the signs of skin aging.
3. Moisturizing performance: Anti-aging cosmetic raw materials should have good moisturizing performance, capable of maintaining skin moisture and preventing skin dryness and aging.
4. Safety: Anti-aging cosmetic ingredients should have good safety and not cause irritation or allergic reactions to the skin.
5. Sustainability: Anti-aging cosmetic ingredients should be sustainable and be able to be produced and used under environmentally friendly conditions, without causing pollution or damage to the environment.
