How to reduce the number of tomatoes

In the cultivation of tomatoes in greenhouses, it is very important to promote the orderliness of fruits, reduce the number of defective fruits, and improve product quality, which is directly related to the level of economic benefits. How can this be done? The key is the application of integrated management. Practice shows that by doing the following four measures, we can achieve our goals.

Lose the “Drawing” and “Car” to learn from the principle of not leaving the pepper in the pepper planting, remove the first and the second flower or fruit from the earliest flowering in the flower ear, reduce the nutrient consumption, and accumulate sufficient nutrition to supply the above After flowering and fruiting, it can make the size of the head of the fruit uniform, and the maturity period is basically close.

More flowers, less fruit, choose the best

For each flower on the flower head to open more points, usually leave 4 to 5 high quality fruit per panicle, must point 8 to 9 flowers, wait until the young fruit diameter to 1 cm, then choose to stay 4~ Five fruits of similar appearance and size were then sterilized to remove large fruits, malformed fruits, defective fruits and pests and fruits. When it matures, the fruit, whether it is a head or a uniform appearance, can be sold at a high price.

To promote coloration before ripening When the tomato fruit is mature, use 40% ethephon 100 ~ 200 times liquid, with the brush point above the stalk to the spike branching stem 5 ~ 8 mm, can promote 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, each application of 10-20 kg of potassium sulfate per acre can increase the weight of the fruit without hollow fruit. , good taste, bright color.

Having grasped the above four management measures, the tomato planted is not only of high quality, tidy and tidy, but also of high yield.
