What do tomatoes not grow with in general? How are tomatoes grown?

Potatoes are a "difficult brother" for tomatoes. There is a common problem between the two, that is, they are both susceptible to epidemics, viral diseases and rotten pathogens. If you plant tomatoes and potatoes together, whether it is tomatoes or potatoes, if one of them is infected with the disease, the other side will be quickly spread and the disease will develop.

In order to prevent unnecessary inconvenience, it is better to plant them separately. Cucumbers are shallow-rooted, and should be watered frequently when planting cucumbers, and if the water is not enough, the cucumbers will wilt and fall off when they are ripe. Tomatoes are different, tomatoes have a well-developed root system, and the temperature of the soil is specified to be moist, and there is no need for too much water.

In the case of a lot of water, it is very easy to cause breathing difficulties at the root of the tomato, and it is obvious that the root rot will not be conclusive. At the same time, tomatoes need to be turned over when they are planted, but if you accidentally shovel the shallow-rooted cucumbers, the cucumbers will die. Tomatoes are also not good if they are grown with vegetable crops.

Tomatoes and eggplant peppers are similar to those of the Solanaceae family, which are susceptible to pathogenic bacteria and are not suitable for planting together. Tomatoes should not be planted with cucumbers and beans, because cucumber beans are tied and climbed, and they may be messed with tomatoes. Tomatoes should not be planted with turnip greens, and turnip greens will be covered underneath.

In addition, if you go to pick tomatoes twice a day, you will continue to trample on other crops. A variety of crops are also not suitable for growing together. Tomatoes require a lot of water and nutrients throughout the growth cycle, and in order for tomatoes to increase yield, quality and efficiency, it is necessary to carry out relevant supervision from each time of development.

To put it simply, the agricultural products related to tomato cultivation should not compete for the nutritional value components and water necessary for their growth and development, otherwise it will immediately affect the improvement of tomato quality and production. The same is stipulated for the illuminance, which endangers each other's growth and development. Both cucumbers and tomatoes require a strong amount of light.

During the abundant growth period, they will block each other's light, endangering growth and development, especially tomatoes are more seriously affected, and under low light conditions, it is very easy to cause flower and fruit drop and vigorous growth. Natural ventilation in the field is restricted, which is not conducive to air flow, and the carbon dioxide concentration between plants is low, which is harmful to plant photosynthesis. Because of the prevention of diseases, the cotton wool needs to be fertilized dozens of times during the growth period.

The fruit of tomatoes can also be damaged and should not be consumed. In addition, there are also green peppers and Chaotian peppers that cannot be neighbors with tomatoes. Tomatoes are not good as the stubble of the above plants, and they will infect tomatoes with pathogenic bacteria and viruses according to the soil.

Cucumbers and tomatoes have many common diseases, such as gray mold, wilt, virus diseases, etc., and the diseases can be serious when planted together, especially virus diseases can spread rapidly between tomatoes and cucumbers through aphids. In order to make full use of the large space between the rows of cucumber seedlings, fast-growing rapeseed, cabbage or bagged oyster mushrooms can be planted between the rows, and coriander and celery can be planted in the low part between the rows. Conservatory.

Leeks are planted on the earthen wall of the greenhouse to realize the full and rational use of the greenhouse.

Tomatoes are better not to be planted with cucumbers. Tomatoes should be planted with seedlings before transplanting, and it is enough to keep sufficient water and fertilizer during the growth period.

Do not plant with cucumbers, after this period must be watered less, to ensure that the soil is moist, to loosen the soil in time, and then to have the right light, spray pesticides, and prevent insect pests.

Tomatoes can be grown with low-growing vegetables such as spinach and lettuce.

Tomato cultivation techniques.

Plot selection. You should choose deep soil, good drainage and irrigation, good ventilation and ventilation, and do not plant nightshade vegetables within 2 to 3 years, and do not choose areas without irrigation facilities for cultivation.

Breed selection. Choose varieties that are disease-resistant, high-quality, high-yield, resistant to storage and transportation, have good commerciality, and are suitable for market demand, such as Jintiewang.

Sowing seeds and raising seedlings. Sowing time in early March to early April is appropriate, according to the actual local situation reasonable arrangement of sowing time, the use of fertilizer ball way to carry out plastic film and small arch shed seedlings, and with the well-rotted farmhouse fertilizer mixed soil evenly pinched into a fertilizer ball of about 5 cm, and put a seed, evenly arranged with nutrient soil covering, at the same time apply a dilute water, covered with plastic film. Finally, it was covered with a small arch that was 8 meters wide and 8 meters long.

When there are 3** leaves growing, it is necessary to remove the film in time to ventilate and cool down, train the seedlings, and then plant them after a week.

Colonization management. Soil preparation and application of base fertilizer: 15 to 20 days before planting, apply 7 to 8 square meters of well-rotted high-quality circle fertilizer per mu, or 5 to 6 square meters of livestock and poultry will be stacked and fermented with the same amount of crop straw and then applied 100 to 150 kg of rotted cake fertilizer, using east-west high ridges.

If the greenhouse is cultivated 20 days before planting, the greenhouse is covered with film, and after the film is buckled, the bottom water is filled with ditching to irrigate the soil.

Planting method and density: plant spacing is kept at 50 to 60 cm, row spacing is kept at meters to meters, and 2000 tomato seedlings per mu are planted. At the same time, it is better to plant after 4 p.m. on a sunny day or on a cloudy day, and after planting, it is necessary to water the planting water thoroughly in time, and then water the seedlings once after 3 to 5 days.

Field management. Erection and pruning: when the tomato plant is about 30 cm high, it should be tied to the vine in time, and the "human" herringbone bracket is mostly used to erect the scaffold, and after the bracket is laid, the tomato trunk is fixed on the bracket with a plastic rope in the shape of an inverted figure 8, and a single stalk is used for pruning, each plant retains 5 to 6 spikes of flower spikes, and each spike retains 4 to 5 fruits.

In particular, it is necessary to remove the excess side branches in time and remove deformed fruits, diseased fruits, and excess fruits. In the later stage of growth, the lower old leaves and diseased leaves should be removed in time to reduce nutrient consumption and disease propagation, and enhance ventilation and light transmittance.

Cultivating weeding and cultivating soil: tomato seedlings can be cultivated and weeded after slowing seedlings, cultivating must be shallow and not hurt the roots, at the same time, remember that the tomato should be cultivated 2 to 3 times during the whole growth period.

Fertilizer and water management. Drip irrigation or dark irrigation should be used for watering, and the seedlings should be watered in time after planting, and the seedlings should be watered slowly after 3 to 5 days. The relative moisture of the soil is maintained at 60 to 70 percent in spring and 75 to 85 percent in summer and autumn.

Top dressing in time according to the length of the growing season and growth conditions. After deducting the basal fertilizer part, it is applied with water several times. It is worth noting that it is necessary to resolutely put an end to the use of organic fertilizers that have not been harmlessly treated, and it is advisable to use oil cakes and various biological fertilizers.

1. Tomatoes can be grown together with vegetables such as dwarf lettuce beans and celery.

2. The three-dimensional cultivation mode of spring intercropping dwarf bean is suitable for early spring cultivation in plastic greenhouses. Tomatoes and laidou are intercropped, and 1 meter wide flat furrow is used. Tomato varieties are sown in mid-January and planted in mid-March, with 2 rows per furrow and 20 cm plant spacing in North China.

Harvesting begins in mid-May and seedlings are pulled in late June.

3. The three-dimensional cultivation mode of autumn intercropping celery is carried out by using plastic greenhouses. It is cultivated in a flat furrow with a width of a meter, and it is cultivated in a furrow with a partition. Tomato medium and late maturing varieties, seedlings are raised in late July and planted in late August, with 2 rows per furrow and a plant spacing of 25 cm.

Leave 4 5 fruits per spike and 2 3 spikes per plant. The greenhouses are covered with plastic film in late September and harvested in early December. Celery seedlings were raised in early to mid-July, and planted in greenhouses in early September, with 8 rows per furrow, row spacing of 15 cm, and plant spacing of 10 to 12 cm.

Tomato is a light-loving crop, with a light saturation point of 70,000 lx and a suitable light intensity of 30,000 50,000 lx. Tomato is a short-day plant, in the process of shifting from vegetative growth to reproductive growth, the basic requirements are short-day, but the requirements are not strict, some varieties can bud and bloom in advance under short-day sunshine, and most varieties bloom earlier in the sunshine of 11 13h, and the plant grows robustly.

In fact, tomatoes do not have very strict requirements for soil, because the roots of tomatoes are more developed, can extend to deeper soil, and nutrient absorption is relatively fast. However, vegetable farmers must want to grow tomatoes on a large scale, so in order to increase the yield of tomatoes, they should choose fertile, soft and deep soil when planting tomatoes. By controlling the pH value of the soil, such a soil environment can promote the growth of tomatoes, increase the yield of tomatoes, and maximize the economic benefits of their own planting.

Tomatoes have a higher yield and a greater need for water, so when planting tomatoes, it is necessary to ensure that there is sufficient water and the soil moisture content is large. Moreover, tomatoes have different requirements in the growth stage that does not pass, for example, when tomatoes are seedlings, it is necessary to ensure that the soil moisture content is about 60%. The water requirement is higher during the fruiting period, and we need to ensure that the soil water content is in a stable state, if it changes too much, it is easy to affect the growth of tomatoes.

Fruit cracking, fruit drop, causing various pests and diseases and other problems, so when we plant tomatoes, we should control the water to improve the water retention of the soil and prevent water loss.

Tomatoes are relatively resistant to low temperatures and can grow at a temperature of around 11 degrees Celsius, but the optimal growing temperature is around 20 degrees Celsius. But as with tomatoes, the temperature requirements vary at different stages of growth. For example, after sowing, the temperature should be controlled at about 25 degrees Celsius, if the temperature is lower than 10 degrees, it will seriously hinder the germination of seeds and prevent germination.

After the seeds germinate and break the soil, the temperature is controlled at about 22 degrees Celsius to ensure the growth of the seedlings. And we need to control the temperature difference between day and night to provide the best environment for tomatoes to grow. During the growth process, the temperature should be well controlled, too high and too low will affect the growth of tomatoes to varying degrees.

Tomatoes need to be fertilized several times during their growth. In general, tomatoes enter the flowering and fruiting period after planting. When the first spikes of tomatoes begin to swell, watering and fertilization are carried out.

In general, about 10 kg of amino acid water-soluble fertilizer is applied downstream of each mu of land. When the tomatoes grow to a diameter of about 2 cm, top dressing can be used in combination with top dressing. Generally speaking, about 20 kg to 25 kg of 45% potassium sulfate nitrogen, phosphorus and potassium controlled-release fertilizer are applied per mu of land.

Combined with watering, keeping the soil moist is conducive to the absorption and utilization of fertilizer. Tomatoes can keep flowering and bearing fruit.

Tomatoes are easy to grow, and they don't have high requirements for the growing environment. Tomatoes can grow well in general land, just pay attention to weeding and fertilizing at the seedling stage.

Tomatoes are relatively easy to grow, for example, seeds need soil, the environment is generally alkaline soil, and his requirements for soil quality are higher humidity and looser soil.

1. Affected by the temperature, tomatoes are not suitable for planting in June, June is about to enter the summer, the temperature rises at this time, the sunlight is relatively strong, the soil moisture is insufficient, it is easy to lead to drought, and the planting environment is not conducive to the growth of tomatoes.

2. The most suitable time for tomato planting is spring and autumn, tomatoes like warm and warm, so the temperature needs to be controlled, and the temperature is too low will also affect its survival.

Dear, I'm sorry to keep you waiting, I'll answer for you. Tomato is a light-loving, temperature-loving, moisture-loving crop, and has high requirements for soil during growth, especially for soil fertility and irrigation water. In the process of growing tomatoes, it is necessary to pay attention to its companion plants, some plants and tomatoes cannot be planted next to each other.

Tomatoes should not be planted next to crops such as eggplant, peppers, potatoes, beans and strawberries because these crops and tomatoes are prone to mutual infection, cross-infection and toxin-protecting diseases. For example, tomatoes and eggplants belong to the same Solanaceae family, and they are susceptible to solanum disease, and their growth habits and soil requirements are very similar, so they cannot be planted next to each other. Secondly, tomatoes should not be planted next to fruit trees such as peach, plum, and cherry trees.

The roots of fruit trees will release some substances, which affect the normal growth of surrounding plants, and produce oxalate and other substances that can easily damage the nutrition and poor growth of tomatoes. In addition, tomatoes and crops containing a lot of acidic substances such as oranges, lemons, hawthorns, and fresh dates should not be planted next to each other. Therefore, when planting tomatoes, you should choose a certain distance from crops such as eggplant, peppers, potatoes, beans, strawberries, etc., and avoid planting them on the same plot with fruit trees such as peach, plum, and cherry trees, as well as plants with a high content of acids.

This reduces problems such as cross-infection, oxalate contamination, and ensures healthy growth and normal yield of tomatoes.

Tomatoes cannot be grown with Solanaceae. Eggplant seeds, potatoes, peppers and other crops belonging to the Solanaceae family are grown together. This is because Solanaceae plants secrete a toxin called solanine, which can cause problems such as slow growth, yellowing of leaves, and death of plants belonging to the same Solanaceae family, affecting the yield and quality of tomatoes.

In addition, tomatoes should not be placed together with strawberries, sesame, peanuts and other crops that are susceptible to pathogens, otherwise it is easy to cause the spread and spread of diseases. Therefore, when planning planting, it is necessary to pay attention to separating similar plants from crops that are easily contagious to each other, so as to avoid the spread of diseases and affect yields.
