What should I do if the tomato grows and can t sit still?

1. Control the temperature of the greenhouse.

Tomatoes are a temperature-loving crop, so the temperature in the greenhouse should not be too high, the maximum should not exceed 30 degrees during the day, if the temperature exceeds 35 degrees and lasts for more than two hours, then it will affect the flower buds of tomatoes. The temperature at night should not be lower than 12 degrees Celsius and higher than 18 degrees Celsius, if the night temperature is too high, the stems of the tomatoes will grow and the flowers will fall. To carry out artificial cooling, in the weather with high temperature and greater sun, shade the greenhouse at noon when it is the hottest, or in the greenhouse [splash water to cool down physically, etc.].

Lower the temperature for good fruit set.

2. Spray growth regulators.

Tomatoes can be sprayed on the foliar surface of tomatoes with agents such as estorantin to adjust the growth rate of tomatoes, and thicken the stalks of tomatoes, but not excessively. Before use, you can spray a small amount as an experiment, and then make the corresponding amount according to the growth of tomatoes. If the dosage is excessive, it will not only not promote the growth of tomatoes, but also inhibit the growth of tomatoes.

Try to spray in the afternoon on a sunny day, as this will reduce the chance of pesticide damage.

3. Remove the leaves to protect the fruit.

If you find that tomatoes have more leaves, you can remove the leaves that are growing better to protect the growth of tomatoes. However, the number of fruits on each plant should not be too much, because if the fruit represents an excess of nitrogen fertilizer, the excess nitrogen fertilizer will lead to an imbalance in the nutrient absorption of tomatoes. In addition, too much fruit will cause nutrients to be absorbed by the lower fruit, and the upper fruit will not have enough nutrients to flower and bear fruit, resulting in the fruit and flower drop of the upper fruit.

During the flowering and fruiting period, it is also necessary to pay attention to reasonable fertilization, otherwise it will also cause uneven nutrition.

4. Supplement nutrients.

If it is found that the tomatoes grow too fast or the water in the tomatoes evaporates quickly due to the high temperature, resulting in calcium deficiency, you can spray some foliar fertilizer containing boron, calcium and other trace elements, which can also reduce flower and fruit drop to a certain extent, and in the case of too high temperature, you can also spray a little anther, which not only protects the flowers, but also increases moisture.

Strengthen pollination during the flowering period, if the number of plants is relatively small, the wind is not enough, and the bees can not be recruited, artificial pollination can be carried out, and the top should be pinched off, learn to beat the branches, know how to choose, and strengthen the light, moderate moisture, reduce the erosion of pests, more observation, more management, can not let it develop.

Summary. Hello Do a good job of water and fertilizer management, and light, pruning!

1.Tomatoes do not bloom may be caused by improper water and fertilizer, and it is necessary to provide reasonable water and fertilizer for the plant in the later stage, 2It may also be that the tomatoes do not receive enough light during the growth process, and they need to provide sufficient light for the tomatoes in the later stage, 3

It may also be that the tomatoes are pruned too little, and the tomatoes need to be pruned in time to help the plant save nutrients.

What should I do if the tomatoes are planted and grow well, but they do not bloom?

4.The use of pesticides to treat the early stage of high temperature or excessive watering or large amount of nitrogen fertilizer leads to vigorous growth, nutritional disorders, photosynthetic products are only used for the growth of top branches and leaves, not to the flower buds, affecting the flower bud differentiation and flowering, it is recommended to use the Bakah Yangduole and Huaduole alternate spraying, control the vigorous growth, make it grow in a balanced manner, and transfer nutrient distribution at the same time, promote the transport of photosynthetic products to the flower buds, promote the differentiation of flower buds, improve the fertilization rate of pollination, and promote fruit set.

If there are flower buds, they just don't open.

It may be a problem with pre-management.

Now it's a matter of management.

It is recommended to spray alternately with Nabekah and Flower Tole to control the growth and balance the growth.

Is there one? I didn't buy it.

Dear, I'm here for Q&A customer service.

Dear, there is a general agricultural market.

Pro, you can also take online shopping.

**All on.

See your personal convenience.

Thank you. than the heart].

1. Too high or too low temperature will lead to flower organ defects;

2. Insufficient sunshine, too dry and too wet bed soil, and lack of phosphate fertilizer will affect the normal differentiation of flower buds;

3. Excessive root injury, insufficient nitrogen fertilizer, and low temperature during planting;

4. In the later stage of growth, pruning and pruning are not timely, there is too much nitrogen fertilizer, and the plants are too luxuriant, so that the growth and development of the plants are unbalanced;

5. Too much or too little moisture.

1.Pollination. The flowers of the tomato are bisexual, and one flower has both pistils and stamens.

It is a self-pollinating plant, so tomatoes grown in the open air are pollinated by wind or bees, so naturally there is no need to worry about pollination. But if your tomatoes are planted on closed balconies, then you need to find a way to pollinate them.

To give? Pollination. Solution: When the tomatoes planted on the closed balcony are blooming, it is a good solution to blow the cold wind on the flowers of the tomatoes with a hair dryer. Or brush each flower with a dry, clean brush (cotton swab) to help pollinate.

2.Planting too densely.

The balcony only has such a large space on the ridge, and it is not easy to find soil and break the soil. So some people will grow too many tomatoes in a small area. At this time, every tomato is malnourished, and it is good to be alive, and it is even more difficult to bloom and bear fruit.

It's too dense. Solution: If the planting density is too high, it will also affect ventilation. Tomatoes are more likely to get sick, so the result is naturally not to be used and regretted. Planting less doesn't necessarily mean harvesting less, so be sure to sow boldly and maintain a reasonable density.

3.The temperature is too high.

There is so much architecture in the city. Under the heat island effect, the temperature difference between day and night is too small when it is above 35 degrees Celsius during the day and above 26 degrees Celsius at night. Tomatoes will grow vegetatively, the branches will be longer, the leaves will be more, and the need for flowering will be diminished.

Even if it blooms at this time, it is easy to fall off, and the fruit is small and easy to fall off.

Tropical heat island effect.

Solution: If you're in a place where the summer temperature is too high, try to avoid growing tomatoes during the hottest months of summer.

4.Poor lighting.

All fruits and vegetables need to be exposed to sufficient sunlight, and the light saturation point of tomatoes is 70,000 lux, so it is generally necessary to ensure that the light intensity is more than 3-35,000 lux. If the balcony of your home has less than four hours of sunlight a day, tomatoes will definitely have problems such as poor growth, less flowering, and difficult fruiting.

Sun balcony. Solution: Keep the tomatoes in a sunny place for more than six hours, and even better if it's a sunny balcony.

5.Soil or fertilizer issues.

A few years ago, an agricultural technology company in Wenzhou was sentenced to pay nearly one million yuan in compensation for the pH value of its tomato cultivation substrate, which caused farmers to not bear fruit due to the problem of the pH value of its tomato cultivation substrate. If your soil is too acidic or too alkaline, it will also cause the tomato to bloom and not bear fruit.

Tomatoes are fertilizer-loving plants, and if the soil is too poor, it will lead to less flowering and no fruiting.

Compost. Solution: Increase the pH of the soil; When fertilizing, we must adhere to the principle of thin fertilizer and frequent application, and try to choose organic fertilizer to improve the soil environment.

When conditions permit, the use of compost can not only increase soil organic matter, but also improve soil vitality, allowing tomatoes to bloom and bear more fruit.
