How to manage greenhouse tomatoes to reduce deformed fruits?

In recent years, the deformed fruit of tomatoes in greenhouses has caused a headache for growers, because such fruits not only affect the appearance of tomatoes, but more importantly, directly affect income. The shape of the tomato is one of the important criteria for judging the quality of the tomato, once the tomato is deformed, it will greatly reduce the quality of the tomato, thereby losing its commodity value and reducing the income of the grower. And once the most important tomato deformed fruit appears, it can't be **, only cause losses.

So how should we, as growers, manage tomatoes to reduce the appearance of deformed fruits?

The main reasons for the production of tomato deformed fruits and control measures:1. The temperature is not suitableThe main reason for the deformed fruit of tomato is the poor quality of flower bud differentiation, and the temperature is too high or too low will affect the differentiation of tomato flower bud, resulting in the production of deformed fruit.

Prevention and control measures:Reasonably control the temperature in the shed, so that the daily temperature is kept at 20 25, the temperature should not be higher than 35 for a long time, and the night temperature should be kept at 12 15, and the low temperature below 10 should not occur for a long time.

2. Improper use of dipped flower potions:

The use of dipping anthrus is a measure that growers will do, but if the dipping antre is not used properly, it will also cause the production of deformed tomato fruits, such as excessive concentration, not only will there be deformed fruits, but also the possibility of "burning flowers".

Prevention and control measures:Follow the instructions to properly apply the dipping agent and avoid repeating the dipping effect. Try not to dip the flowers at high temperatures, so as not to evaporate the water in the solution and cause the concentration of the dipping agent to increase!

3. Light, water and fertilizer:

If the light is insufficient, the photosynthesis of the tomato will decline, and the tomato nutrient supply will be insufficient, resulting in the weakening of plant growth, the failure of flower buds to develop normally, and the deformed fruit. This can also happen if the supply of water and fertilizer is insufficient, or if there is an imbalance of nutrients.

Prevention and control methods:Do a good job in field management measures, prune and prune in time, increase the ventilation and ventilation of tomatoes, and increase light transmittance. Scientific watering and fertilization, mainly organic fertilizer, timely top dressing, and supplementing the nutrients required for crop growth.

In the flowering stage of tomato, pay attention to the use of boron fertilizer at the seedling stage, spray boron fertilizer and calcium fertilizer. At the seedling stage, potassium dihydrogen phosphate can be appropriately supplemented and sprayed, which can not only promote flower bud differentiation, but also improve plant strength.

In the later stages of tomato management, it is necessary to pay attention to picking some old leaves to prevent the formation of some sunburn fruits or some tomato fruits with poor coloring. Reasonable pruning, teeth grinding, thinning flowers and fruits, and removing some deformed young fruits. At the same time, it is necessary to pay attention to the use of hormones and avoid excessive concentrations.

Keep the temperature at around 25 degrees. Regularly add nitrogen and potassium fertilizers to tomatoes to promote the growth of plant rhizomes, maintain proper light and ventilation. Control pests and diseases.

When everyone buys tomatoes, they like to buy those big, red and round tomatoes, which are more refreshing to eat. Most of the tomatoes on the market today are grown in greenhouses, and if farmers do not have the skills to grow them, it is likely to cause the tomatoes to appear deformed. In fact, these deformed fruits were foreseen at the beginning, but the farmers did not notice them, so in order to reduce them, they had to manage them before they bloomed.

In the process of planting, it is also necessary to ensure the growth environment of Sun Qin tomatoes, and the warmth and nutrition should be sufficient. <>

If you want to reduce the probability of deformed tomatoes growing in greenhouses, you need to manage the seedling stage of tomatoes. When the tomato seedling stage, try not to let the young tomato seedlings be affected by bad conditions such as high temperature or drought, so as to ensure that the seedlings can be differentiated normally in the process of growth, so as to fundamentally reduce the phenomenon of deformed tomatoes. <>

In the summer, the surrounding temperature is rising, and the temperature in the greenhouse will be even higher at this time, and the climate will become very dry, although the light is very good, but in general, this environment is very conducive to the growth of tomato seedlings. At this time, farmers should make full use of the surrounding light and temperature conditions to cultivate healthy plants. During this period, the use of base fertilizer must be sufficient, and a reasonable ratio should be carried out.

Under the condition of ensuring that their soil conditions are good, farmers should plant tomato seedlings, and focus on the roots of tomato seedlings with hoes to ensure that the soil environment is fluffy. If farmers find that their tomatoes are deformed, the fruit is relatively low or the fruit setting is difficult, they can use the method of topping and changing the head. When the tomatoes have set 2 or 3 spikes, the growth point of the plant should be removed, and a side branch that is growing vigorously should be retained.

Generally, the growth and development of side branches are relatively late, and if the differentiation of flower buds is affected in the early stage, topping is a good method.

Be sure to manage the hand of the friend. Usually you can apply more fertilizer, but also pay attention to the management of tomatoes, pay attention to the filial piety of tomatoes, you need to pick the ripe Bishenhuai tomatoes in time, and change the growth direction of tomatoes in time in the process of tomato growth, so that you can better prevent tomato deformity, can also improve the yield of tomatoes, and ensure the sales of tomatoes.

During the management period, we must pay attention to the problem of water and fertilizer, but also pay attention to the disease situation, regular watering and fertilization, can avoid the appearance of deformed fruits. The temperature is controlled at about 25, we must use the agent reasonably, pay attention to the light adjustment, but also pay attention to the addition of water, Huai Bu must have prevention and control measures, but also have management experience, so as to avoid the appearance of deformed fruits.

If you want to reduce deformed fruits, you should avoid high temperature irradiation, pay attention to the moisture of the soil, pay attention to the soil grinding and air permeability, and regularly fertilize to reduce the number of watering; The solution is to fundamentally reduce the deformed seeds, and try to avoid stunted seed development.

1.Varieties with large fruits, thin skins and thick cork layers should be avoided, as this will reduce fruit cracking.

2.We can carry out targeted management in "special times". For example, when tomatoes are in bloom, the temperature at night should be kept above 10 degrees Celsius, and as the situation develops, increase the amount of nutrients**; When the fruit sets or the fruit is enlarged, appropriate topdressing and watering, watering evenly to prevent uneven drought and flooding, resulting in tomato cracking.

3.Generally, longitudinal dehiscence fruit tomato dehiscence fruit calcium deficiency, transverse dehiscence fruit boron deficiency calcium, and another point, boron can promote calcium absorption, when tomato boron deficiency will cause calcium is not easy to absorb, calcium deficiency leads to aggravation of dehiscence fruit, boron promotes carbohydrate operation, is important for fruit formation and pollination, so boron calcium deficiency leads to tomato plant dehiscence.

4.Through the activation of biological bacterial activity, the addition of soil organic matter improves the structure of soil aggregates, and a good root system needs nutrient maintenance, so we can choose or cooperate with fertilization to solve these problems. Spraying boron calcium is used to prevent tomato fruit cracking.

In addition, early application of calcium boron foliar fertilizer can also increase fruit set rate and improve fruit enlargement, sweetness and color. At the same time, water-soluble fertilizers containing organic fluorine can be used for irrigation or drip irrigation, which can not only meet the nutrients required for the growth of tomato flowering fruits, but also prevent the phenomenon of premature senescence of tomatoes.

5.It is recommended that vegetable farmers ventilate when the temperature reaches 27-28 in the morning after the dew has subsided, which is conducive to reducing fruit cracking. In windy weather, it avoids tomato fruits being blown away by strong winds, and also effectively reduces fruit cracking.

6.Greenhouse planting planting sowing time must be selected well, can be in the Spring Festival, this time the benefit is better, so according to the actual local planting, usually choose in August to the middle of the orange or early September, and water management, watering can, grafting sit in front of the first ear of tomato fruit, do not water when the pier, mainly to make the tomato roots grow down, until the tomato grows to the size of a walnut, the length of the second ear fruit to the size of a broad bean, the third ear of fruit just flowering, then you can water.

If you want to do a good management of Heng Hunger Town, you must first ensure that the temperature of the greenhouse is more comfortable, and then you must also control the proportion of watering and fertilization, and you need to control the growth rate of tomatoes and control the speed of light, so that tomatoes can grow better and prevent cracking fruits.

Vegetable greenhouses should be irrigated in a timely manner, to ensure that filial piety hidden soil moisture replenishment is sufficient, and to do a good job in the management of the response, to keep the greenhouse has enough sunlight, temperature and humidity appropriate, timely observation of the growth of tomatoes, to avoid long-term sunlight.

It is very important to choose the planting varieties of Xihong type persimmon, and the planting of varieties with large fruits, thin skin and thick layer should be avoided. Reasonable water and fertilizer, watering should be small water and frequent watering to prevent uneven drought and flooding, resulting in tomato cracking.

The management work that needs to be done well is to manage the tomatoes, the management of planting technology, the management of water and fertilizer, the management of water and fertilizer technology, the management of diseases, and the prevention and control of diseases.

It needs to be managed scientifically, we must pay attention to the amount of watering, not to water too much water, pay attention to the nutrients of the soil, pay attention to the drainage of the soil, pay attention to the light, and pay attention to ventilation. Defeated.

1. Ventilation and temperature regulation Since the tomatoes are planted in the cold winter, the first task is to increase the temperature in the shed, enhance the light, and promote the slow seedling. At this time, the temperature should be controlled at about 25 -30 during the day and 15 -20 at night. In order to prevent the seedlings from growing.

Tomatoes are sensitive to temperature during the flowering period, especially 5 days before flowering and 3 days after flowering, and less than 15 and higher than 30 are not conducive to flowering, pollination and fertilization. In the fruiting period, the temperature should be controlled at about 25 during the day, about 15 at night, and the temperature difference between day and night should be about 10.

Second, pruning and fruit preservation in the first ear of fruit after sitting in time to hang the vine, greenhouse pruning generally adopts a single stem pruning method, while tomatoes are prone to side branches, to be erased in time, the bottom leaves should be removed in time, in order to improve ventilation conditions, reduce the occurrence of various diseases.

3. Watering and fertilization Tomato roots are relatively developed, have strong water absorption ability, and require large water during growth, but should not be soaked in water when watering. After the first ear of fruit sits, if too much watering will cause growth, resulting in flower drop, so after planting to control watering, when the fruit grows to the size of walnut, start watering and fertilizing, you can wash with watering to apply honey to high organic fertilizer or Protan compound fertilizer. In the future, depending on the growth of the plant and the weather conditions, pick a crop of fruit combined with fertilization and watering once.

Fourth, the prevention and control of various diseases in the early stage of tomato growth, there are relatively few diseases, mainly to prevent and control the occurrence of early blight, gray mold and other diseases, for these diseases, you can use Yinfari and Xiangnong No. 2 or Shi Jiale and other agents for prevention and control.

Precautions for growing tomatoes in winter greenhouses, tips.

When planting, we should pay attention to temperature, light and fertilizer, and the temperature should be particularly suitable, which will be more conducive to the growth of tomatoes, and also prevent pests and diseases, and timely thinning flowers and fruits.

First of all, we must cultivate seedlings, and then we must strengthen management, we must ensure that the soil is moist when watering, do not water too much, clean up stagnant water, do a good job of vegetables and fruits, drink pesticides, prevent pests, and strengthen ventilation management.

It is necessary to do a good job in the management of water charges, and to do a good job in the management of land, to do a good job in the prevention of some diseases, to do a good job in watering, to do a good job in adaptation, and to do a good job in greenhouse management.

It may be a lack of organic fertilizer, or it may be a lack of light, or it may be that the outside temperature is very low, and sometimes the temperature difference is very large, which will lead to deformed fruits.

It is caused by insufficient nutrients, or it may be caused by low temperature and drought, so we must pay attention to watering and temperature.

It may be that the fertilizer and water management is not particularly good, and the leaf fertilizer is sprayed very much, so that there will be some deformed fruits.

There are many reasons for this, such as insect infestation. My family has also grown tomatoes before, and this tomato still bears a lot of fruit, but some of them will be deformed. For example, after some tomatoes have been bitten by ants or mosquitoes, their growth is prone to deformity.

I remember when my mother used to grow tomatoes, it was because ants climbed up and gnawed these tomatoes, and some of them only broke their skins, and when they grew later, the broken skin turned into pimples, and they looked ugly. <>

There are also some birds, if they have bitten or pulled some feces on it, it may cause the tomatoes to appear deformed, after all, the place where the birds have pulled the feces, there are germs, and the light is less so that the temperature is not enough will appear deformed, which is also normal. This also tells us that when planting tomatoes, we must avoid some insect pests, and making a few scarecrows in the place where tomatoes are grown, or hanging a few clothes fluttering there, can also effectively drive away these birds and insects. <>

Nutritional deficiencies and improper pollination are also prone to tomato deformities. The cultivation of tomatoes also requires a variety of nutrients, and for tomatoes to grow deformed fruits is very large, in the case of a lack of three elements. The first is calcium deficiency, in fact, it is normal for calcium-deficient tomatoes to grow deformed, after all, tomatoes also need some trace element calcium.

The second trace element, then boron, don't underestimate this element, it is easy to cause deformed flowers and deformed fruits. Of course, it is also necessary to properly fertilize and supplement some nutrients, especially some compound fertilizers, which are more convenient to use, can supplement a variety of trace elements, and reduce the occurrence of deformed fruits. <>

In addition, when spreading pollination, if the operation is not done properly, or even the pollen quality is not good, then there will be a situation of growing deformed fruits, so when we choose pollination, we must choose some pollen of good quality, otherwise it will affect the appearance.
