In tomato cultivation, promoting the orderliness of fruits and reducing the number of defective fruits are directly related to the level of economic benefits. Practice has shown that doing the following four measures can achieve high efficiency.
Lose "pump" and "car" Learn from the pepper planting without leaving the door pepper, remove the earliest flowering first and second flower or fruit, reduce nutrient consumption, to accumulate adequate nutrient concentration after supply of flowers and fruits , that is, after the inhibition of the former, the fruit size can be consistent, and the maturity is close.
More flowers, less fruit, the best choice for the United States on each flower on the flower to open more points, leaving 4-5 high-quality fruit on each ear, must point 8-9 flowers, wait until the young fruit diameter to long At 1 cm, choose another 4-5 fruit with similar appearance and size, and then remove the deformed fruit, fruit and fruit. When it matures, the fruit, whether it is a head or a uniform appearance, can be sold at a high price.
To promote coloring before ripening When the tomato fruit matures, use 40% ethephon 100-200 times, with a brush point above the pedicel 5-8 mm from the spike branching can be promoted early maturation and coloring, Increase production. But do pay attention to the following: First, do not point in the "joints" (stems and branches at the junction), otherwise it will cause serious fruit drop phenomenon; Second, do not spray ethephon or stain on the fruit , Otherwise it will make the plant premature aging, but also affect the fruit of the commodity, and the ripened fruit intolerant of transport; Third, the concentration of ethephon can not be too high, the time can not be too early, otherwise it will make the fruit premature, resulting in reduced production Reduced, and not resistant to storage and transportation.
Topdressing potassium fertilizer, tomato lack of potassium coloring, prone to tendon rot disease and low yield. Therefore, after the end of flowering, when the fruit diameter exceeds 3 cm and begins to enter the expansion stage, with the application of potash fertilizer, 10-20 kg of potassium sulfate per acre will be applied to increase the fruit's weight without hollow fruit. , good taste, bright color.
Grasping the above four management measures, the tomatoes that were grown not only had good quality, were tidy, and had less defective fruit, but also had high yields.
