How to choose and handle tomato seeds
Tomatoes are aliased to tomatoes. The fruits are nutritious and have a special flavor. Can be eaten raw, cooked, processed into ketchup, juice or whole fruit pots. The nutritional value of tomatoes has now been accepted by many people. Therefore, tomatoes are grown in many places, especially the United States, Russia, Italy and China. So, how to choose tomato seeds before planting tomatoes? Tomato seeds are not only related to the growth of tomatoes, but also related to the yield and quality of tomatoes. Here we will describe how to select and treat tomato seeds.
According to the growing season, cultivation methods, market demand choose the right tomato varieties. Excellent tomato varieties should have the characteristics of disease resistance, high yield and high quality. At the same time, the indicators such as maturity, fullness, mechanical damage, germination rate, and germination potential were also examined. The quality of the seeds of the qualified tomato seed should be higher than 98%, the seed color is pure, no mildew, the purity is higher than 95%, the germination rate is higher than 88%, and the moisture content is less than 8%. Higher scientific research units or seed departments purchase seeds to prevent economic losses from buying fake seeds. The demand for seed cleanliness is very high, especially in the case of large-scale aircraft seeding, which has a serious impact on production. In agriculture, we generally select seed hair dryers, first conduct a rough analysis of the seed's seed purity, and then select seeds. The Clarity Analyzer or Seed Clarity Observatory performs a more detailed analysis of the seed's clarity. The 1000-grain weight of seed is the main indicator of the fullness of the seed. Generally, it is measured using a seed counting instrument. Generally, the seed weight of a large-fruited tomato seed is about 3.2 grams. In order to increase the number of years of tomato seed production and utilization, it is necessary to create good conditions and extend seed life in the seed storage process. When the seeds are stored, the seeds should be fully dried. The relative humidity of the air in the storage should be reduced as much as possible, and the temperature should generally be below 5°C. The lifespan of a typical tomato seed is 3 to 6 years, and the lifespan of production is 2 to 3 years.
Seed treatment has a far-reaching impact on the growth of seeds: pre-sowing seed treatment can reduce tomato seed colonization, increase seed vigor, promote uniform emergence and enhance seedling resistance. The first is soaking, which can be treated with trace elements or gibberellin, and then the seeds are sucked in moisture. Seed disinfection can choose warm soup soaking, pharmacy soaking and dressing seed dressing, there are a variety of pesticide soaking, formalin, potassium permanganate, and raddew. After these treatments, we can germinate it. After the seeds are soaked and disinfected, germination is required to promote the rapid development of the young embryos. There are two ways of seed germination, pot germination and sand germination. During seed germination, we can use the seed germination box to provide the most suitable temperature and humidity for seed germination. You can also choose the light box or artificial climate box. The difference between the two is that the light box can only adjust the temperature and light intensity, while the artificial climate box can adjust the temperature and light intensity while also being able to adjust the humidity.
