The role and method of tomato low-temperature refining
Tomato is one of the common vegetables in daily life, which is rich in nutrients and has a unique taste, and is deeply loved by people. In the process of tomato planting, low-temperature budding is an important technical means, which plays an important role in improving the quality and yield of tomato. This article will introduce in detail the role and method of tomato sprout refining at low temperature.
First, the role of low-temperature bud refining.
1.Promotes seed germination.
Under suitable low temperature conditions, tomato seeds can be treated at low temperature for a period of time, which can promote their germination. This is because under low temperature conditions, the physiological activities inside the seeds are inhibited to a certain extent, which makes the nutrients inside the seeds more concentrated, which is conducive to the germination of seeds.
2.Improve the quality of seedlings.
The quality of tomato seedlings can be significantly improved by refining buds at low temperatures. Seedlings that have been treated at low temperatures have a faster growth rate, a more developed root system, and a more robust plant. This helps to improve the stress resistance and adaptability of tomatoes, laying a good foundation for later growth.
3.Increase production.
With low-temperature sprouting technology, tomato yields can be significantly increased. Tomato seedlings treated at low temperatures have a shorter growth cycle and more robust plants that are better able to adapt to various environmental conditions, resulting in higher yields.
4.Improve quality.
Low-temperature budding can also improve the quality of tomatoes. Tomatoes that have been treated at low temperature have more balanced nutrients, a more delicious taste and higher nutritional value during the development process.
Second, the method of low-temperature refining buds.
1.Seed selection and treatment.
Choose healthy, plump tomato seeds and wash them with water to remove impurities and broken seeds. Then the disinfection treatment is carried out, and the seeds can be soaked for 15 minutes with an appropriate amount of potassium permanganate solution to kill the pathogenic bacteria on the surface of the seeds.
2.Cryogenic treatment.
Put the sterilized seeds into a sealed plastic bag, remove the air inside the bag, keep them moist, and then put them in a low temperature of 0 5 for low temperature treatment. The treatment time is generally 7 to 10 days, and the temperature should be kept stable during the treatment period to prevent excessive temperature fluctuations from affecting the physiological activity of seeds.
3.Sowing and raising seedlings.
Sow the seeds after low temperature treatment in fertile soil, taking care to keep the soil moist and controlling the temperature between 20 and 30. When the seedlings grow to a certain height, the seedlings should be thinned and transplanted to ensure that the seedlings have good growth space and light conditions. During the seedling raising period, attention should be paid to strengthening the management of water and fertilizer, and the appropriate amount of nitrogen, phosphorus and potassium fertilizers should be applied in a timely manner.
4.Field management.
Transplant the tomato seedlings after low temperature refining to the field, and pay attention to maintaining a reasonable row spacing and plant spacing, so as to facilitate the growth of plants and ventilation and light transmission. During the growth period, fertilizer and watering should be applied in time to meet the water and nutrients required for plant growth. At the same time, it is necessary to pay attention to the prevention and control of pests and diseases, regularly inspect the situation in the field, and take timely prevention and control measures when pests and diseases are found.
5.Harvesting and storage.
When the tomato fruit is fully ripe, it can be harvested. Care should be taken when harvesting to avoid damage to the fruit. After harvesting, the tomatoes should be stored in a cool and ventilated place to avoid direct sunlight and high temperature and humidity affecting the fruit quality. During storage, it is necessary to keep clean and hygienic to prevent the occurrence and spread of pests and diseases.
In conclusion, tomato low-temperature sprouting is an effective technical means to improve the quality and yield of tomatoes. Through the implementation of reasonable low-temperature treatment, sowing and seedling, field management and harvesting and storage, high-quality tomato fruits can be obtained.
