How are cherry tomatoes grown out of season? What are the techniques used in the cultivation process

It should be planted in greenhouses during the winter months. During the planting process, the temperature should be adjusted to about 25 degrees. Apply organic fertilizer regularly, water appropriately, keep the soil moist, and pay attention to the prevention and control of pests and diseases.

It mainly relies on greenhouses for off-season planting. The cultivation process requires the application of greenhouse technology. Drip irrigation technology in greenhouses, artificially assisted pollination technology. Humidity and temperature control technology.

1.Variety selection: Choose the middle and late maturing varieties in the infinite growth type, and plant Taiwan ruby (i.e., the new saint girl), which has a long production period, high yield, and strong heat and humidity resistance.

2.Plot selection: Cherry tomatoes are more adaptable to soil, but it is better to use loose and fertile loam or sandy loam soil with convenient drainage and irrigation.

3.Sow seeds at the right time and cultivate strong seedlings:

1) Seedbed preparation. The seedbed should be sheltered from the wind and sun, and well drained. 667 square meters of field need to raise 6 7 square meters of seedbed, 35 40 square meters of seedbed, seedbed soil subsoil per 667 square meters of 1500 kg of decomposing acquaintance manure, which is covered with 8 cm thick nutrient soil.

The nutrient soil is half of the fully decomposed organic fertilizer and half of the fertile soil of the unplanted Solanaceae crops, mixed and sieved 7 to 10 days before sowing, mixed with 5 kg of superphosphate, sprayed with carbendazim for soil disinfection, and stacked for later use.

2) Sowing date. Sow seeds appropriately early to extend the harvest period as much as possible. The use of small arch shed seedlings can not only sow seeds early, but also reduce the occurrence of seedling diseases. It is usually sown in late April.

1. Watering.

If the planting water is sufficient, there is no need to water again until the first panicle flowers and sets fruits. If the planting water is less, you can open a ditch in the furrow to water a small amount of water, and choose a sunny day in the morning. The first spike of flowers is watered for the first time after fruit setting, and the water requirement is large in the fruiting period, and the water is watered every 5-6 days, and it is required to see dry and wet.

Reduce watering at harvest time to prevent fruit cracking.

2. Top dressing.

After the first panicle flower fruit set, combined with watering, 10 kg of nitrogen, phosphorus and potassium compound fertilizer per mu, 10 kg of compound fertilizer per mu when the first ear fruit turns color, in order to promote fruit development, and then top dressing 1 time when each two ears of fruit, and the amount of top dressing is 10 kg of compound fertilizer per mu.

3. Temperature management.

The cultivation temperature of the protected land is higher than that of ordinary tomatoes, which is required to be more than 10 at night, 20-25 during the day, and no higher than 35 at the highest.

4. Pruning.

Cherry tomato plants are tall and poorly erect, and when the plant grows to 50 cm, it is inserted to prevent lodging. The growth of side branches is strong, and the double trunk pruning is generally carried out, leaving 2 strong branches first, and erasing the others. Generally, it is not topped, and the old leaves on the lower part are removed in time when they turn yellow to reduce nutrient consumption.

5. Thin flowers and protect fruits.

In early spring, when the temperature is low, pollination is poor and easy to fall flowers, so you can use 2,4-day to apply the newly opened calyx and flower stalk (only need to apply 1 time). Cherry tomatoes bloom and bear more fruit per panicle, and 20-30 fruits with good fruit set are selected and the rest are removed.

If the way is wrong, everything will be in vain. The first thing we should pay attention to when growing tomatoes is the temperature. In daily planting, greenhouse planting can get better benefits, but open air planting does not have such a good effect.

Because of greenhouse planting, it can effectively control this temperature, generally speaking, the temperature of small tomato growth is about 24 degrees is more appropriate, if it exceeds this temperature or is lower than this temperature, it will naturally affect its growth. It is not good to control the humidity and the time of light when planting in the open air, so it is best to choose greenhouse planting. <>

A good seedling can achieve twice the result with half the effort, because it has strong disease resistance and reduces the occurrence of diseases, so that a high-quality harvest can be obtained. If you want to get a better harvest, I don't think it's necessary to save this seed money, it's best to choose to buy some varieties that have been improved on the market, so that the disease resistance is stronger, it's easier to plant well, and you can get a bumper harvest. <>

The earth can give birth to life dumplings and tomatoes, and it also needs a good piece of land. When we choose to plant, it is better to choose some more fertile land, and then these lands will be better if they are more breathable. Generally, when we plant, we have to put the apprentices Qihang in a row, so that the drainage can be better, and it is more conducive to the root growth of the tomato, and it can also increase a certain degree of air permeability.

Tomato It needs to be climbed to a certain extent, so it definitely needs to be racked. If you don't set up a frame, it is easy to cause some pests and diseases, because tomatoes will easily attract some insects after they are ripe, especially on the ground, it is easy to attract ants. The erection frame should also do a good job of ventilation and lighting, and some too dense ones should be pruned to a certain extent in order to have a good harvest.

It is necessary to pay attention to the growth of plants, prepare suitable varieties for planting, be sure to pay attention to the situation of fertilizer, pay attention to ventilation, pay attention to light, pay attention to watering, and fertilization.

The condition of the land, the amount of watering, the time of sunlight, weeding, fertilization, these are all issues that need to be paid attention to, and they are all needed in the planting process.

First of all, it is necessary to pay attention to the appropriate planting spacing, and must prevent some diseases, and then must ensure the fertility of the soil, and then it is necessary to choose the right cultivation season, to do a good job of seedling work in advance, and then it is also necessary to treat the seeds in advance, the temperature should be grasped at about 20 degrees, and the seeds must be disinfected.

To choose the right variety for planting, we must pay attention to the temperature, pay attention to the fruit, timely fertilization, watering, pay attention to the prevention and control of pests and diseases, and pay attention to the time of sowing.

You can cultivate in the greenhouse, choose the appropriate cultivation method, pay attention to the renovation of the soil, pay attention to the way of raising seedlings, and pay attention to the density of planting.

Cherry tomato is a special type of cherry, because the tomato cultivated in this way looks particularly like a cherry, so many farmers will also affectionately call it cherry tomato, in fact, everyone often eats this kind of tomato in life, which is the main raw material of cold vegetables in Western food, and it is also a relatively high-end fruit, so it has aroused the love of many people. <>

First of all, if you want to breed cherry tomatoes with large yield and good color, then you must first choose a good variety of cherry tomatoes, the climate and sunshine length of each region are different, so you must combine your own region, choose a cherry tomato variety that is suitable for the local climate, strong disease resistance, and good quality.

Secondly,Before planting cherry tomatoes, be sure to apply organic fertilizer to the groundBecause the cherry tomato picking period is relatively long, so the key to obtain high yield is to apply foot fertilizer to the ground, you can choose farmhouse fertilizer, these natural fertilizers can improve soil structure, improve soil biological activity, can also promote the growth of cherry tomato plants, and will also improve the ability to resist diseases and insects, thereby increasing yield and improving quality. <>

InWhen planting cherry tomatoes, be sure to pay attention to the distance between the two plantsPlanting at the right time, and being sure to control the distance, in this way, each plant can produce good quality cherry tomatoes. <>

It doesn't matter what kind of crop,The most important thing is the control of pests and diseasesCherry tomatoes may occur during the growth of a variety of diseases, so at this time, when you see any white spots or black spots on the leaves or roots of the plant, you must pay more attention to identify what kind of virus it is, and then choose the appropriate agent to spray.

Growing cherry tomatoes is not an easy task, we need to observe it every day, and there are many places that use brown sugar to increase the yield of cherry tomatoes, so if you are interested in growing cherry tomatoes, you might as well give it a try.

Choose high-quality varieties, good varieties have a particularly strong impact on cherry tomatoes.

It is very important to plant cherry tomatoes and choose the right varieties and buy the right seeds, even if the management of good cherry tomato varieties is not so good, one plant can bear three or four hundred, which is spectacular. At present, there are many varieties of cherry tomatoes, and it is necessary to give preference to the varieties suitable for local cultivation. We mainly plant Jingdan No. 1 and Jingdan No. 8 cultivated by Beijing Vegetable Research Center, and cherry tomatoes and millennium selected by Nongyou Seedling (China).

First of all, when planting, you must choose the land with relatively fertile soil, and in the process of fertilization, you must choose farmhouse fertilizer, do not use fertilizer bought outside, and also often water the plants to prevent the occurrence of pests and diseases.

When planting, you should pay attention to the surrounding temperature and humidity, and also pay attention to the problem of air, so as to ensure the germination rate, and in the process you should also do a good job of field management, so as to be able to cultivate more.

Tomato seeds are soaked in 25% carbendazim 1000 times solution for 8 hours at a temperature of 60 °C, which not only sterilizes, but also wakes up dormant seeds, drains them, and cannot be washed. Wrap it in a wet towel, put it in the environment of 45 °C - 55 °C to promote germination, water it with 45 °C warm water to buy seedlings or individual seedlings during the germination process, and bury 2-3 cm of soil on the soil mound or seedling substrate when planting. After planting, water once to make the root system and soil stable and good.

When the topsoil is not dry or wet, hoe and loosen the soil. Row once every 7-10 days, such as a special drought, and then water and hoe after 7-10 days.

The appropriate seedling age for spring tomato cultivation is 50 to 70 days, and the seeds are sown 50 to 70 days before planting, usually immediately after the local frost period, when the ground temperature at a depth of 5 to 10 cm has stabilized through 12 degrees. Tomato planting time: spring tomato, sowing seedlings from November to December, although tomatoes are self-flowering, that is, male and female on the same flower, without deliberate pollination can bear fruit on their own, especially in the open field planting of the usual natural wind blowing and bees flying back and forth, can help complete pollination.

When planting persimmon seedlings, pay attention to the spacing and do not plant too close. The planting of tomatoes, most of them choose to plant seedlings, so when transplanting into the land, try to have some independent growth space for each tomato, and choose 2-3 years without planting solanaceae crops (heavy stubble will have multiple hazards such as residual diseases and insects and missing soil nutrients), convenient drainage and irrigation, fertile, loose and flat garden for seedbed, deep rake and crush to make a box. The width of the compartment is meters, and the height of the compartment is meters.

Prepare some wet cow dung first, the fresher the better, crush the flesh of the tomatoes together with the seeds and mix them in the cow dung evenly, and smear them on the wall [choose a ventilated wall], try to be as thick as possible, generally about 2 cm is appropriate, and the cow dung will not fall down. Pruning: Tomatoes have a well-developed root system and strong branching ability, and the main vine has a side bud for every section it grows.

If it is not removed, it will make the tomato plant impermeable, pests and diseases will be frequent, and it will also consume a lot of nutrients from the tomato.

When cultivating cherry tomatoes, the planting technology is to choose a very good seedbed, and the soil should be very deep, but also to soak the tomato seeds in potassium permanganate sterilization, and then the sowing of cherry tomatoes, after sowing the cherry tomato seedlings to manage, usually to strictly control the temperature and humidity of cherry tomato growth, but also to often fertilize the seedlings, these are the cherry tomato cultivation technology.

First of all, you should first learn professional cultivation techniques, and you should also spray pesticides regularly, and at the same time, you should also prescribe the right medicine, and you also need to strengthen water and fertilizer management, and you should also do a good job of loosening the soil.

Before sowing, soak seeds, germinate and other seed treatments, do a good job of disinfection of sheds and soil before planting, and then master the temperature and fertilizer management, and also timely control of pests and diseases.

In northern China, planting is generally in mid to late December. When planting, draw crosses or punch holes on the plastic film according to the plant row spacing, open holes and plant seedlings, water enough planting water, and then seal the opening of the plastic film after the water seeps down. The specific cultivation methods are as follows:

In accordance with the scientific requirements of soil testing and formula fertilization, land preparation and fertilization, full application of fully fermented and decomposed organic fertilizer or biological bacterial fertilizer, and soil conditioner (medium and trace elements). It is important to choose good varieties with high yields and disease resistance.

First of all, it is necessary to supplement the tomatoes with trace elements, spray phosphorus, potassium and boron foliar fertilizers when flowering, and add brassin to use together. Several operations in a row can increase the yield and income of tomatoes many times, and the land is best able to ridge, because cherry tomatoes basically need to be ridged and planted, so that it will be easier to control, and secondly, there must be the most good drainage and water source, which is also very important.

The seedling bed of cherry tomatoes must be watered first, the watering can be appropriately small when sowing in early spring, and the seedbed should be filled with enough water in summer, and the seeds should be evenly sown after the water seeps down, and then covered with 1 cm of sieved soil. 3-5 grams of seeds per square meter of seedbed, 6-8 square meters of seedbed per mu of planting area After the successful germination of cherry tomato seeds, it is necessary to plant cherry tomatoes. When planting cherry tomatoes, it is important to choose those soils with relatively rich soil, and then the fertility of the soil must be sufficient, and it is best to use sandy soil, because sandy soil can quickly drain stagnant water.

The disease will harm the leaves, fruits, and stems of cherry tomatoes, and is generally controlled by manganese-zinc or manganese-zinc for sen; Yellow and white seedlings are mainly caused by soil, and should be fertilized reasonably to supplement the calcium content of the soil In terms of fertilization management, in addition to the application of plantar fertilizer, it is generally necessary to apply 2-3 times of fertilizer after the small tomato enters the flowering and fruiting period, especially the appropriate amount of phosphorus and potassium fertilizer. The first topdressing can be carried out when the first ear begins to swell, its cultivation time is the same as the general tomato cultivation time, you can choose to cultivate in the open field, in the spring, you can choose to sow in February, try to choose to raise seedlings in the protected area, and wait until late April when you can plant.
