Tomatoes are a relatively common vegetable, autumn tomatoes are generally cultivated in greenhouses, in order to grow high-yield and high-quality tomatoes, it is necessary to adopt scientific management to increase the yield and harvest.
Breed selection
In autumn, tomatoes have a higher temperature in the early stage and a lower temperature in the later stage, so you can choose early or medium ripening varieties in the seed bank app, heat-tolerant varieties and disease-resistant varieties, such as Tamiflu, Cayenne, etc.
Use basal fertilizer
Farmhouse fertilizer is an organic fertilizer, which is characterized by improved soil, comprehensive nutrition, low nutrient content, and should be applied at the bottom.
Temperature control
After the tomatoes are planted, the greenhouse should be properly sealed, the temperature in the shed and the soil temperature should be increased, and the temperature difference in the shed should be reduced. Temperature is very important for the growth of tomatoes, and we can control the temperature of the greenhouse through shading nets, reasonable ventilation and other methods.
Rapid rooting and slow seedling
After tomato planting, appropriate rooting fertilizer is used, and enzymatic hydrolyzed fish protein fertilizer can promote the root development of seedlings, and the plant can grow vigorously and quickly pass the slow seedling stage.
Flowering period management
In addition to the appropriate amount of phosphorus and potassium fertilizer applied to tomato flowering, we should also pay attention to thinning flowers and fruits. After tomato pollination, more is not always better, because the plant also has a large amount of nutrients. After the tomato fruit set, it is necessary to supply not only the plant to grow, but also to the fruit to grow, if there is too much, the tomato fruit is smaller and of poor quality. Each panicle is guaranteed to have 5 fruits, so that the upper layer of the plant has a larger fruit, which not only has a high yield, but also has a good quality.
Fruit expansion management
Tomatoes need a large amount of fertilizer at the fruit expansion stage, especially the supply of large elements and high potassium fertilizers, 7-8 kg of high potassium large elements water-soluble fertilizer can be applied per mu, and 7-15 days can be washed and applied once.
Field management
Irrigation and top dressing, planting and watering 3% compound fertilizer or 10% manure water to fix the roots. After 10 days of planting, 3% compound fertilizer was applied in combination with tillage. During the whole growth period, according to the growth of the plant, top application 4-5 times. Pay attention to nitrogen control in the early stage, when the fruit of the first layer has the size of walnut, apply 10 kg of urea per mu. After the 3-layer fruit sits firmly, apply another 10 kg. Irrigation should be carried out in time when the surface is whitish, usually after 4 p.m. At the same time, pay attention to draining stagnant water to prevent excessive humidity from inducing diseases.
