Tomatoes are not easy to set fruits, how to improve them?

Temperature management, the temperature in the shed should not be too high, especially at night, otherwise there will be a situation of stalks growing and flowers will be easy to fall. The temperature in the greenhouse can be reduced by spraying water in the shade, and the spraying of Kao 3 can be used to inhibit the growth of the main shoot and promote the differentiation of flower buds. Removing leaves, some of the vigorous growing leaves can be removed to adjust the growth of tomatoes, and moderate watering, top dressing, boron-calcium foliar fertilizer in the growth stage, and spraying vegetable fruit Zhuang Tiling in the flowering and fruiting period of tomato to improve pollen quality, enhance the circulation of fruit setting rate, so that tomato production and high quality.

It should be watered and fertilized in time, and at the same time, it is necessary to ensure sufficient light, strengthen water and fertilizer management and field management, spray some pesticides in time to remove insect pests, and also pay attention to the setting of temperature, and spray some nutrient solution regularly.

Ventilation management must be strengthened, watering should not be too much, there should be no stagnant water, and fertilizer should be applied regularly.

First of all, during the tomato fruit setting period, we must increase nutrients and water more, and pay attention to sun protection, you can water at about 10 o'clock in the morning, or at three to four o'clock in the afternoon, which can be improved.

After the tomato bears fruit, it is proposed to immediately cut off the ripe fruit, so that the small fruit can digest and absorb nutrients stronger, and it is also necessary to water every 5 7 days to maintain the soil moisture, and it is also necessary to immediately top dressing light fertilizer compound fertilizer to prevent the lack of nutrients, and the feeding is to let it accept the abundant sun, to prevent the occurrence of steep growth, and then reduce the production of fruit.

Management plan for tomatoes after they bear fruitPick the fruit

After the tomatoes gradually hang fruit, it is very likely that the situation of small fruits will occur, at this time, the perfect fruit needs to be picked immediately, and each branch can save 3 or 4 fruits, so that the soil can immediately give nutrients, promote the hanging small fruits can ripen faster, which is beneficial to the growth of tomatoes.

Moderate watering

Tomatoes can be watered every 5 7 days during the fruit-bearing period, if it rains, then there is no need to water the tomatoes, keep the soil moist, but do not have to make the soil too wet and cold, just water it moderately, so that the tomatoes can grow stronger.

Proper fertilization

It can also be given immediate topdressing and light fertilizer compound fertilizer, fill nutrients to tomatoes, prevent the lack of nutrients, cause tomatoes to hang fruit again, reduce the amount of fruit production.

Plenty of light

In fact, tomatoes love the sun, especially when tomatoes are in the fruit-bearing period, putting them in a bright environment can make tomatoes digest and absorb nutrients in the soil stronger, so that the small fruits can be quickly perfected, and the tomatoes can be prevented from growing steeply.

Tomato fruit hanging after quality assurance and high yield management method technology 1, according to the growth of the plant and the nutrient status of the soil immediately comb the fruit, too many fruits, will improve the transverse rate of small fruits and deformed fruits, generally a single branch to retain 3-5 fruits is appropriate.

2. Fertilizer and water management is generally carried out at the same time. The watering of tomatoes after hanging fruit should be maintained at about 50% in accordance with the standard of seeing dry and wet, so as to prevent water storage from harming the photosynthesis of rhizomes, which is not conducive to ensuring production and income.

3. To prevent diseases during the fruit-bearing period, the leaves can be sprayed with Tianshan wind leaf fertilizer 2-3 times to achieve the purpose of disease prevention. Pest control is mostly carried out after the occurrence of purposeful medication, and the actual effect is good.

4. Effective fertilizer, including the application of nutrients such as light fertilizer, Peng calcium, magnesium and zinc. The application of nutrients should refer to the instruction manual, too much will increase the capital investment and can not get the estimated actual effect.

5. Pay attention to thinning branches and sun exposure, and apply shade chiffon if necessary to reduce the possibility of sunburn.

When the tomatoes can be watered according to the number of hanging fruits, when the number of fruits is relatively small, it can be watered once a week, if the number of fruits is more, it can be watered once every 4-5 days, each watering to keep the soil moist environment, no water can be generated. After the tomatoes bear fruit, they can be applied every 10 days with well-rotted human fertilizer and fast-acting phosphorus and potassium fertilizer. Pay attention to the excessive amount of nitrogen fertilizer before flowering and fruiting, otherwise it will lead to the growth of seedlings and eventually cause flower and fruit dropping.

In order to prevent the invasion of pests and diseases during the fruit-bearing period, it is necessary to prevent the occurrence of pests and diseases. For example, leaf mold, whitefly, late blight, etc., which should be sprayed with pesticides in time to effectively eliminate the disease. In addition, keep it ventilated and well-lit.

After hanging the fruit, be sure to maintain the temperature, apply more fertilizer, but also pay attention to the number of watering, if too much watering, it will also cause the taste of the fruit to become lighter, and secondly, to ensure a long time of light, so that the taste of tomatoes is better, and also to check in time, remove those persimmons that do not grow well, so that the fruit can grow fuller.

Once such a situation occurs, it is necessary to ventilate in time, and also to water in time, and at the same time should be fertilized in time, and some pesticides should be sprayed in time, and then it is also necessary to prune the branches and leaves to protect the roots.

Be sure to water more, pick in time, pay attention to the ways and means, and don't fertilize.

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.

Summer is coming, it is the season when tomatoes are on sale, but many farmers do not know that the tomatoes they grow are not only not high, but even many tomatoes do not set fruit, so what is the reason why tomatoes do not set fruit? How to improve the fruit set rate of tomatoes?

Tomatoes do not set fruit for sake.

One. Seedling management method, in the case of seedling management method, if the temperature is high, then stubborn growth is too vigorous, then it will harm the growth of the reproductive system, which will cause plant yellow leaf disease, such as the temperature of seedling emergence exceeds 30 °. In other words, high temperature management methods, flooding and large fertilizers, the nutrient content of the plants is too vigorous, the growth of the reproductive system is reduced, the growth of the reproductive system is weakened, and the fruit setting rate will be reduced.

When planting seedlings, it is necessary to soak pots, control fertilizer, and control temperature.

Two. Management methods during the flowering and fruiting period. During the flowering period, it is generally recommended to manage the quilt between 25 and 26 degrees Celsius, and if the temperature does not reach it on a rainy day, you can open the quilt in the morning.

It is possible to reduce the amount of watering the flowers, or not to water the flowers. For example, if the temperature does not rise, the air outlet of the professional counterpart can be opened in the afternoon to ventilate the room. That will get the harmful substances out of the iron shed.

That is beneficial to improve the temperature of the shed, be sure to put the quilt early, roll it up early, increase the temperature, improve the sun exposure time, and improve the growth of the plant.

How to increase fruit set in tomatoes.

1. Temperature management methods. The temperature of the arch canopy is not too high, no more than 30 in broad daylight, and the temperature of 35 in the summer continues to occur for 2 hours above the flower bud differentiation of tomatoes, and it is generally 12 to 18 at night, especially in the evening, the temperature is not suitable for too high, otherwise the stem will be steep and long, and the flower will fall. You can reduce the temperature in the greenhouse according to the method of spraying cold water in the shade, choose the afternoon shade on a sunny day, spray cold water every 1 to 2 days, reduce the temperature in the greenhouse, and with the decrease in temperature, you may slowly sit down the flowers.

2. Spray growth conditioner. You can use the booster to carry out leaf spraying, or use dwarf Fengling to carry out acupuncture application, that is, to dig holes around the seedlings, put dwarf Fengling into the hole, can manipulate the rise of tomatoes, so that the stems of tomatoes become wider and stronger. It is necessary to note that the dosage is not suitable for too large, you can do the following experiments first, such as 2 to 1 sprayers can be used first, and then decide the amount to use according to the details, if you use too much, the tomato plant will be stunted for a long time.

At the same time, you can choose to carry out the sprayer at noon on a sunny day, so that the actual effect is good, and it is not easy to cause fertilizer.

3. Cut off the leaves. A portion of the growing leaves can be removed to regulate the growth of tomatoes.

4. Fill with boron-calcium leaf fertilizer. In the case of the lack of calcium due to the rapid growth of plants or too high temperature, which causes the rapid volatilization of water, etc., will cause the crops to digest and absorb boron and calcium is insufficient.

5. The application of anthers. In the case of higher temperatures, the concentration of anthers can be moderately reduced, that is, the same medicine can moderately increase the water flow rate, which can promote full bloom and fruit set.

Tomatoes should be watered more, fertilized more, pruned branches and leaves, pinched off the heads of tomatoes, don't let tomatoes grow all the time, and some of the leaves of tomatoes that don't grow well should also be knocked off, and you can eat some nitrogen fertilizer or potassium fertilizer to increase the rate.

Protective measures should be taken when it is a seedling in advance, you can wrap a plastic wrap on it, and then water it properly after germination, and add some fertilizer to the roots, so as to improve the fruit setting rate.

It is necessary to add fertilizer, increase photosynthesis, and water, at a temperature of 20, so as to increase the fruit set.

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.

The common reasons for poor flowering and fruit setting of tomatoes are: excessive nutrition, which causes the plant to grow vigorously and affects flowering and fruit setting; During the flower bud differentiation period of tomatoes, the temperature is too high, and it is easy to fail to complete normal pollination or poor fruit development, which affects the flower bud differentiation.

Which of the workarounds:

1. Temperature management: the temperature in the shed should not be too high, no more than 30 during the day, about 12-18 at night, and the temperature should not be too high at night, which is prone to stem growth and falling flowers.

2. Supplement boron and calcium: the indispensable element of tomatoes in the flower bud differentiation period is boron calcium, boron calcium can better promote flower bud differentiation, but calcium moves slowly, boron is not easy to be absorbed, and the general foliar fertilizer can not achieve the effect of supplementing boron calcium at the same time.
