What happens when you have more fat tomato leaves

In addition, due to the high concentration of soil fertilizer, it is easy to cause plants to absorb water, and tomatoes will be in water loss, and the leaves will shrink and wilt at this time.

Attach great importance to and pay attention to the growth and development position of tomato root seedlings in a timely manner to ensure that tomato seedlings reach the complete growth and development position of the roots, and closely combine with the soil to be completely fertile, and the seedlings will no longer be watered and fertilized on the spot within two and a half months of the early harvest period. Tomato mature seedlings spring fertilization management needs to be carried out before and after the growth period, the specific amount and frequency of fertilization also need to be properly managed for dosage control, usually spring fertilization can be from tomato seedlings growth 10-15 days for a short period of time, and then apply phosphorus potassium nitrate and phosphorus compound fertilizer. It is also recommended to increase the amount of phosphorus fertilized at least once a week in autumn or when tomato seedlings are beginning to be harvested.

In order to ensure that the bulb roots of this green tomato can grow well, it is necessary to strengthen the disinfection management during root growth in a timely manner. For the first time, there is no fixed sequence of cleaning flower buds, during the flowering period of fruit trees, it is not only necessary to pay careful attention to the arrangement of each fruit tree branch and carefully prune each hanging vine, but also need to make full use of the traditional cleaning mode of single rod pruning and single pruning and single pruning when taking care of each fruit tree branch. After cleaning each branch at once, the fibroblast tissue of the main stem of the whole tomato can fully and quickly absorb various nutrients in the body and the sunlight reflected by the cells.

Due to the concentration of various nutrients and chemicals in the body, tomatoes can also grow rapidly and achieve a healthier growth state in the normal natural growth environment.

Depending on what kind of fertilizer you use, if it is a chemical fertilizer, it will die. If the feces are feces, the leaves will be oily green and nutritious.

There will be a lot of white circles on the fruit of the diseased tomatoes, and different white circles represent different diseases, so let's talk about the different manifestations of these two diseases in detail below.

This white circle is a symptom of canker disease, a bacterial disease that can flare up from seedling to harvest. The first symptoms are mainly distorted edges of the lower leaflets, drooping and dehydration.

At the peak of the disease, white spots appear on the leaves and petioles, and dark streaks appear on the branches, spreading up and down, causing the stems to crack and turn brown until they affect the fruit, appearing this white circle that resembles an eye.

The disease prefers low temperatures and high humidity environments, where bacteria enter through the breach and spread through routine activities such as watering. If it is planted in a greenhouse, it is easy to spread germs when the temperature in the greenhouse is high and the leaves or fruits are dewy for a long time.

In addition, after the fruit reaches the green ripening stage, some white circles occasionally appear on the surface. After this happens, there is not much abnormality in the fruit, and such a white circle does not affect the development of the fruit, but it does not slowly disappear either.

The second type of white circle is a symptom of gray mold. The reason for this symptom is that the conidia germinate on the surface of the unripe fruit, the mycelium cannot continue to grow on the fruit, and the fruit surface is resistant to Botrytis botrytis infection.

The canker bacteria can overwinter on seeds, diseased bodies, soil and weeds, and can survive in the soil for 2-3 years. The incidence is high and severe in warm and humid, poorly ventilated, rainy, prolonged dew condensation, and alkaline soils. At 25 - 28 years old, it is easy to get sick when the relative humidity exceeds 80%.

After the onset of the disease, water supply for irrigation and the application of fertilizers can easily lead to the spread and epidemic of the disease over a large area.

Botrytis is a fungal disease caused by pathogen invasion from host wounds or senescent organs. Lack of light, poor ventilation, excessive humidity, constant rain, etc. are all important factors that contribute to this disease.

In addition, nutrient deficiencies and stunted growth can also lead to high morbidity. Temperature 20 23 , ambient humidity greater than 90 %. It is an environment with a high incidence of disease.

From the beginning of March to the first 10 days of April, the disease begins in the leaves, with the highest incidence from late April to late May.

Relevant precautions should be carried out as soon as possible, and preventive measures should be taken. In the process of drug control, it is recommended to alternate several drugs to avoid bacterial resistance and affect the control effect.

Check the dorsal part of the lower lobe for aphids, or spider mites like spiders.

Ingredient 1Regular application of nitrogen fertilizer: compound fertilizer or urea can be applied; 2.

Combined application of phosphate fertilizer and potassium fertilizer: tomatoes are more sensitive to phosphorus leucopod and potassium fertilizer, and can be mixed with the average proportion of chemical fertilizers. 3.Increase the application of organic fertilizers:

During the growth period of crops, the application can be increased according to the soil nutrient status, and the inorganic nutrients can be followed by the invasion of organic fertilizer into the soil, which can improve the absorption efficiency of fertilizer. 4.Appropriate application of calcium fertilizer: it is conducive to improving the quality of fruits, and the application of lime powder after seed grinding can be done; 5.

The amount of fertilizer should be appropriate each time: too much should be applied to avoid the formation of stagnant soil.

When the tomato enters the full fruiting stage, the fruit begins to turn white in the first ear, the first.

2. When the fruit of the third ear expands rapidly, it needs to be topdressed 2-3 times. In addition to the general topdressing of 15-20 kg of fast-acting nitrogen fertilizer per mu each time, in the application of foliar topdressing of tomato, foliar spraying is generally selected in the middle and late stages of tomato growth, that is, the flowering and fruiting period. Therefore, during this period, the tomato grows with greater nutrient consumption, and the root system alone attracts nutrients slowly or insufficiently.

Tomatoes, also known as tomatoes, are nightshade fruit vegetables, which are planted and harvested multiple times at a time, and continue to bloom and bear fruit from the moment they bloom, and are harvested according to their ripeness. In order to maintain its continuous growth, tomatoes are very common in vegetable planting, due to the large market demand, farmers are also very willing to plant, in planting, topdressing foliar fertilizer is a necessary process for tomato growth, which can not only improve the quality of tomatoes, but also increase the yield of tomatoes.

Tomatoes are very common in the market, many people will buy and eat, its ** is not too high, but the nutrition is high and the taste is good, many people will taste and eat. For farmers, in order to make the sales of tomatoes higher, everyone will also take care of them. The common foliar fertilizers sprayed on tomatoes mainly include superphosphate and potassium dihydrogen phosphate solution, which are also the most used in rural areas, especially for tomatoes grown in vegetable greenhouses.

In the process of tomato growth, due to various reasons, the growth of plants is affected, especially the root growth is blocked, the fruit cracks, the growth is weakened, etc., which seriously affects the normal growth of tomato and the improvement of yield, and the reduction of tomato quality, and the growth of tomatoes determines the types of nutrients. Generally speaking, the growth of plants in the early stage of fruiting is relatively vigorous and easy to grow, so less foliar nutrients should be used to promote the growth of stems and leaves, and potassium dihydrogen phosphate and compound fertilizer can be selected. Tomatoes have large plants, many fruits, and a long ripening period, so it is necessary to improve the quality and yield of tomatoes through foliar fertilizer.

Foliar fertilizer spraying was mainly carried out in three time periods: seedling stage, pre-flowering and peak fruiting period of tomato.

You can choose potassium dihydrogen phosphate and fertilizer of Woye granules, these two fertilizers are fused, and then sprayed on the leaves of tomatoes, and it is good.

When applying foliar fertilizer, calcium fertilizer must be selected, the interval must be 5 7 days, and some inorganic fertilizer should be sprayed on the foliar surface.

Foliar fertilizer can be taken according to the 1000 times solution of potassium dihydrogen phosphate mixed with 800 times of urea, and it can be sprayed once every ten days.

Summary. To deal with tomato leaf curling caused by excessive fertilization, the following methods can be used: 1. Reduce the amount of fertilizer:

Reducing the amount of fertilizer applied is the best way to solve this problem. Stop the application of fertilizer, or appropriately reduce the application of fertilizer, so as to achieve the purpose of regulating growth and maintaining decay; 2. Adjust the electrolyte balance with nitrate: excessive nitrate application can regulate the electrolyte balance in the plant, which has a significant effect on leaf curling disease; 3. The application of potassium, magnesium and other trace elements:

Potassium and magnesium not only promoted the growth of plants, but also inhibited the adverse reactions caused by excessive fertilization of plants; 4. Timely weeding and proper watering: timely weeding and controlling the amount of watering can effectively maintain the normal growth of plants.

Dear, I'm glad to answer your questions: how to deal with too much fertilization of tomatoes: how to deal with too much fertilization of tomatoes: how to deal with too much fertilization of Xihong Mengling persimmon is to adjust the electrolyte balance with nitrate:

Shi Zhishan's use of excessive nitrate can regulate the electrolyte balance in the plant, which has a significant effect on leaf curling disease.

To deal with tomato leaf curling caused by excessive fertilization, the following methods can be adopted: 1. Reduce the amount of fertilizer: Reducing the amount of fertilizer is the best way to solve this problem.

Stop the application of fertilizer, or appropriately reduce the application of fertilizer, so as to achieve the purpose of regulating growth and maintaining decay; 2. Adjust the electrolyte balance with nitrate: excessive nitrate application can regulate the electrolytic rolling mass balance in the plant, which has a significant effect on leaf rolling disease; 3. The application of potassium magnesium and other trace elements is adopted: potassium magnesium not only promotes the growth of plants, but also inhibits the adverse reactions caused by excessive fertilization of plants; 4. Timely weeding and proper watering

Timely weeding and controlling the amount of watering can effectively maintain the normal growth of plants.

Foliar fertilizer can be sprayed.

When the tomato enters the flowering stage, you can spray water-soluble fertilizer containing more nitrogen, phosphorus, potassium and trace elements to the leaves, and you can also use trime amino acid foliar fertilizer. In this way, it can provide more trace elements for tomatoes and supplement balanced trace elements, so as to provide more balanced nutrition for tomatoes. Spraying foliar fertilizer during the flowering period can also improve the disease resistance of tomatoes and promote the growth of tomato roots, improving the yield and quality of tomatoes.

Spraying foliar fertilizer for tomatoes in autumn and winter usually causes the air humidity to increase, making tomatoes susceptible to disease, so reduce the frequency of foliar fertilizer spraying in rainy weather, and apply fungicides appropriately during fertilization, and ventilate them in time after fertilization.

When to spray foliar fertilizer for tomatoes.

Tomatoes grown in the open field can choose to spray foliar fertilizer before 10 a.m. or after 4 p.m., these two times are more suitable for the ambient temperature, and the light is not very strong, which can reduce the evaporation of foliar water and increase the efficiency of fertilizer absorption by plants.

Tomatoes planted in greenhouses can be carried out between 10 o'clock and 4 o'clock every day, when the temperature in the greenhouse is relatively high, the tomato will grow faster, which can improve the absorption rate of tomatoes to fertilizer.

For tomatoes, the main purpose of using foliar fertilizer during the flowering period is to preserve flowers and fruits and improve the fruit setting rate, but many people will ask whether foliar fertilizer can be sprayed during the flowering period?

The purpose of plant flowering is to promote pollination, and then form fruits, so as long as the flowering period does not affect the pollination of flowers, after years of technical management, it is not recommended to use foliar fertilizer during the pollination period, even if the foliar spray water is not recommended, because it is easy to lead to poor pollination.

Therefore, in the flowering period of plants, in addition to the pollination period of the use of foliar fertilizer is no problem, which is also conducive to promoting fruit set, but at this stage it is recommended to use foliar fertilizer that is conducive to fruit setting, such as boron-calcium foliar fertilizer, potassium dihydrogen phosphate, etc., if you want to have a good comprehensive effect and good absorption of boron-calcium elements, it is recommended to use boron-calcium foliar fertilizer containing organic acid, and then use it with potassium dihydrogen phosphate.

If we don't know what stage the pollination period is, then just use it according to this: 1-2 foliar sprays before flowering, 2-4 times after flowering, and choose the appropriate time and frequency of use according to different plant conditions.

Symptoms of tomato fertilization

In the early stage of tomato fertilization, there are yellowish white or gray-white irregular spots on the surface of the leaves, and the spots expand with the development of the disease. The edges of the dead spots on the leaves are grayish-white, and the inner mesophyll does not have time to fade green, and it is dark withered green, and it is perforated in the later stage. Unlike diseases, blight does not expand indefinitely.

Under high temperature and drought conditions, the disease progresses very rapidly, and the leaf margins are scorched.

Tomato fertilizer control measures

The main reason for tomato fertilizer damage is that the amount of chemical fertilizer is too large at one time, the root system is damaged, and the absorption function is reduced, which affects the leaves and leads to fertilizer damage. Tomato fertilizer damage not only causes a lot of waste, but also affects the normal growth of tomatoes, and the prevention and control of tomato diseases should be done in advance.

Soil testing formula fertilization according to the different growth periods of tomato fertilizer demand for different soil testing formula fertilization, avoid the use of a single fertilizer, fertilization should be uniform, fertilization should be immediately watered or fertilized with water, so that the fertilizer dissolves into the soil as soon as possible, reduces the concentration of fertilizer, is conducive to the absorption of tomatoes.

Increase the application of organic fertilizer Minimize the amount of chemical fertilizer, increase the application of organic fertilizer, and apply biological fertilizer with organic fertilizer if possible.

Improve the fertilization method The method of layered application and full-layer deep application is adopted to integrate soil and fertilizer and avoid exposing fertilizer to the surface.

Remedial measures Watering immediately after the appearance of fertilizer symptoms, generally watering 2 3 times after the fertilizer damage can be lifted, and at the same time spraying plant nutrient solution to enhance the resistance of tomatoes.
