Preventing Autumn Tomatoes

Every autumn, tomatoes in greenhouses often appear to be inaccessible to flowering and can not stand fruit. The specific performance of some tomatoes can only point a small amount of fruit in one ear; some flower buds are incompletely differentiated; some flowers only differentiate the sepals. There is no stature such as pistil stamens and pollen. If they do not stand, they will lead to excessive growth of tomato plants and absorption of nutrients. As a result, the nutrients absorbed by other organs such as flowers and fruits will be greatly reduced. Growth will be insufficient, resulting in flower buds can not be properly differentiated, thus affecting the normal growth of tomatoes. That is, there is a situation in which "they do not have fruit."

It is recommended to take the following measures to solve

1, temperature management, the temperature inside the shed should not be too high, especially the night temperature, otherwise there will be stalks of the situation, prone to falling. The temperature in the greenhouse can be reduced by spraying fresh water through shading, and the flower bud differentiation can be promoted by suppressing the growth of the main shoot with the promotion of Huawang No. 3.

2, remove the leaves, you can remove some of the vigorous growth of the leaves to adjust the growth of the tomato, and in the growth phase of moderate watering, top dressing, add more calcium boron fertilizer, and spray the fruit during the fruiting period of tomato fruit Zhuang Ti Ling improve The quality of pollen enhances the rate of fruit set in the cycle, allowing the tomato to produce stable quality.

3, artificially assisted pollination, timely artificial pollination in the flowering period of tomato, increase the fruit set rate of tomato, and spraying a new high fat film in the young fruit period to play the role of liquid film bagging, will not affect fruit respiration, fruit rust, Anti-cracking, improve fruit surface coloration and brightness, reduce residual toxicity and improve quality.
