What should I do if I use a plant growth regulator incorrectly, and the tomato does not grow after c

When the tomato is not growing, it is necessary to control the amount of nitrogen fertilizer, which will promote the growth of the tomato, and pay more attention to the temperature, the temperature should be increased by more than 25 degrees during the day, and the temperature should be above 15 degrees at night, and electricity should be used to increase the temperature.

Control the amount of nitrogen fertilizer, increase potassium fertilizer, which will promote the growth of rice, the temperature should be above 25 degrees during the day, and the temperature should be above 15 degrees at night, and it is necessary to supplement gibberellin, which will alleviate the damage.

At this time you can water more, and the temperature must be lower, so that you can do it.

1.When the tomatoes are growing, chemical agents are used to spray, and 800 times of promectoxin, 1500 times of mequat and other regulators can be sprayed, and the concentration should be controlled well to avoid excessive.

2.Carry out water and fertilizer control, control watering, reduce the amount and frequency of watering, reasonable fertilization, and control the use of nitrogen fertilizer.

3.It is also possible to control the elongation by planting the long stems obliquely into the soil.

4.It is also possible to adjust the temperature and delay the fruit thinning time.

<> excessive use of tomato control wang drugs can generally be sprayed with brassin, Bihu and other drugs plus amino acids, humic acid, alginic acid, foliar fertilizer or potassium dihydrogen phosphate alternately sprayed to alleviate the stress resistance of plants and promote their rooting and seedlings. It is recommended to spray 1 time every 5-7 days, and spray 2-3 times in a row.

The excessive use of tomato control drugs can generally be alleviated by spraying brassinin and other drugs plus amino acids, humic acid, alginic acid foliar fertilizer or alternating spray of potassium dihydrogen phosphate in seafood, so as to improve the stress resistance of plants and promote their rooting and strong seedlings. It is recommended to spray once every 5-7 days, and spray 2-3 times in a row.

Fertilization of small tomatoes should be paid attention to the right time and appropriate amount. The so-called timely refers to the application of small tomatoes when needed, such as the discovery of small tomato leaves are light, when the plant growth is weak, fertilization is timely.

As for when to apply what fertilizer, it depends on the different growth and development stages of small tomatoes, such as the seedling stage, you can apply more nitrogen fertilizer, (rotted human urine manure, soybean cake fertilizer, sesame cake fertilizer) to promote the rapid and robust growth of seedlings; During the bud stage, more phosphorus and potassium fertilizers can be applied (chicken and fish offal, bone meal, bran ash: ash made from rice husk burning, containing potassium) to promote the growth of flowers and seeds; Proper control of fertilization at the early stage of fruit setting is conducive to fruit setting.

No matter what period of fertilization should pay attention to the appropriate amount, if too much nitrogen fertilizer is applied, it is easy to form a long growth; Excessive application of potassium fertilizer hinders fertility and affects flowering and fruiting.

The first thing to learn is to cut off some unwanted or even excess branches, because some branches that do not bear fruit will only waste nutrients and will not bring benefits to this tomato, so they should be dealt with in time.

Be sure to water evenly, never let the soil have stagnant water, pay attention to ventilation and drainage, there must be proper light every day, and the light time should be kept at about 3 or 4 hours.

The tomato grows very vigorously, and the reason for the small number of fruits is that the tomato is not pinched in time and the ghost flower is removed, the tomato only needs a trunk, and the excess must be pinched, otherwise it is a waste of nutrition.

Specific usage of mequaticin: 1. When the pepper sedan chair and potatoes begin to have a tendency to grow, in the budding to flowering period, potatoes are sprayed with 1600-2500 milliliters of mequat to the foliar surface, which can control the growth of the rock ground and promote the increase of yield, and the pepper is sprayed with 20-25 milliliters of mequat on the stems and leaves, which can control the growth and improve the fruit setting rate. 2. Spray with a concentration of 4000-5000 mg of mequat solution in the growth point of cabbage (lotus white) and celery, which can effectively control the sherbening and flowering.

3. Tomato seedlings are sprinkled with 50 milligrams of mequat water agent on the soil surface, which can make the tomato plant compact and bloom early. If the tomato is found to grow after transplanting, 500 mg of dilution of mequat can be applied at 100-150 ml per plant, and the effect will be shown in 5-7 days, and the effect will disappear after 20-30 days and return to normal.

Tomatoes are suitable for growing in dry and moist soils, and soil moisture between 60% and 80% is most suitable. There are also requirements for soil pH. The general pH is between 5 and 7.

That said, from slightly acidic to neutral soils, tomatoes are more conducive to growing well. At the same time, it is necessary to grasp the sowing time. Usually the north and south have different seasonal changes, so the north is suitable for spring sowing.

The south is late, and autumn sowing is more suitable for sowing in July and August.

After the tomato seedlings grow, they should be watered more in the early stage of fruiting, which is not conducive to the growth of fruit seedlings. The result is less watering, intermittent watering in the way it gets wet. After fertilization, an appropriate amount of water should also be added to help the seedlings absorb nutrients.

Also drink properly. If fertilization is applied but no water is added, it may also be bad for the growth of tomatoes. If the soil is dry enough to congeal, fertilization will not make the soil any better.

In this way, no matter how much fertilizer is applied, the tomatoes will not grow well.

The concentration of fertilization may also need to be controlled. Too high a concentration is not a motivator for tomatoes, but a detriment. However, if the concentration is too low, it may not have any effect, so when preparing fertilizer, you should read the instructions or consult the information.

Moreover, the fertilizer concentration added to tomatoes at different times is the same. It's not the same. Some may be fertilizers that were added upfront, and some are fake fertilizers when the fruits are ripe.

These are all things that need to be well studied. If you can pay attention to this, you don't want tomatoes to grow well, but it seems that they all have to grow well.

There are too many fruits, not timely thinning flowers, many farmers and friends in the management of tomatoes to obtain yield, how to make tomato plants more fruitful, reluctant to thin flowers. It's a pity that I picked such a beautiful fruit that bears such a luxurious fruit. Generally speaking, racemes can open 5 to 8 flowers, racemes can open 10 20 flowers, if they can all produce fruit, it is obvious that the plant can not provide nutrients for various fruits in time, so the fruit of the whole plant does not meet the variety standard.

Because of the lack of nutrition, the fruit looks small and there are many deformed fruits. After the tomato blooms, it is necessary to thin the flowers in time, and after the first flowering, let the first female bird ripen in time to prevent the dominance of the head flower. If the bean curd is not removed, it will affect the first.

2. The flowering of the third flower and the expansion of the fruit. In general, each inflorescence leaves 4 to 6 fruits, ensuring that each fruit expands with sufficient nutrients**.

It may also be due to the lack of water, at this time, the first thing is to water every day, and also to fertilize at each stage, so that it can play a good role and the tomato can grow faster.

The reason for the slow growth of tomato fruit may be too much nitrogen fertilizer, if there is too much nitrogen fertilizer, the tomato is prone to growth, the reproductive growth is relatively lagging behind, the nutrients absorbed by the tomato root system are too much allocated to the plant, the nutrition of the relative fruit will be reduced, the tomato plant is higher, the leaves are hypertrophied, it is easy to cause poor ventilation, and the light transmittance is poor, so the tomato fruit grows slowly.

Prevention method: tomato seedling growth starts, do not carry out too much watering and fertilization, sit down the fruit, and then water and fertilize, especially nitrogen fertilizer, not too much, in order to make the tomato plant strong, can be combined with spraying plant growth regulators, commonly used to help Zhuang su, uniconazole, etc., regulate the growth of tomato plants, reduce plant height, increase the ability of ventilation and light transmission, spraying plant growth regulator time, should be arranged in the first two or three days of watering. At the same time, the application of nitrogen fertilizers should be reduced, and the proportion of phosphorus and potassium should be increased.

Yes, the soil fertility is poor, the organic matter content is insufficient, and the sandy soil has poor water and fertilizer retention capacity. According to the survey, many sheds are sandy soil, with poor water and fertilizer retention capacity, so the amount of organic fertilizer should be increased to improve the soil.
