How to manage the actual cultivation process of tomatoes? What to look out for?

Tomatoes are a common vegetable, and in its growth process, watering is very important, which is directly related to the growth and development of tomatoes and the yield of tomatoes. Next, I will actually tell us how tomatoes should be watered to ensure the yield of tomatoes from planting to harvest. Tomato watering should not be carried out according to the length of time, but must be watered according to the growth and development of tomatoes, growth and development stage, weather conditions, etc., so as to ensure that the tomato yield profit is maximized.

Transplanting and watering: Tomato seedlings should be watered habitually after the time constant, and the temperature is usually watered once every 2-3 days. The amount of watering is dominated by less, the soil layer is moist and the most suitable is not to water too much, otherwise the tomato seedlings will take root and die very easily.

Watering is best done with a watering can that waters the flowers, as it is very easy to manipulate the flow of water. From the perspective of the regularity of tomato fertilizer demand, the amount of fertilizer at the seedling stage is small, but the nutrition is comprehensive. Abundant nutrients, beneficial to the growth and development of roots, stems, leaves and flowers.

From the time of transplanting to the first ear of fruit sitting, the amount of fertilizer increased and <>

In general, most of the basal fertilizer and soil nutrients can be achieved. If there is too much nitrogen, it is easy to cause madness. From the moment the first ear of fruit sits to the time it is obtained, the amount of nutrients absorbed by the plant surges, and sufficient fertilizer must be provided.

In addition, attention should also be paid to the hazards of environmental conditions to top dressing. In the case of drought, the demand for nitrogen increases; Clammy and cold, the need for potassium and phosphorus increases. The nutrients at the seedling stage of tomato are mainly provided by bed soil.

If the trace elements in the bed soil are abundant and the types are complete, the growth and development of seedlings can be healthy, promote early flowering, and grow and develop quickly. Tomato seedlings have a long seedling stage, and they usually do not produce enough nutrients in the middle and late stages of pregnancy. When something like this happens, it should be mixed with watering and <>

Top dressing is sufficient for manure or urea solution. If the seedlings are raised in greenhouses, carbon dioxide can be added to promote the growth and development of the seedlings. Fertilize as needed.

In tomato production, the intake of various nutrients by tomato plants is not only suitable, but also the highest. In general, when the absorption rate of trace elements reaches an appropriate pointThe plant growth and development are abundant, and the yield is the largest; However, when the intake is at the highest level, the maximum yield may not be obtained. Therefore, it is necessary to grasp the most appropriate situation when applying fertilizer.

When growing tomatoes. Be sure to pay attention to his lighting status. Tomatoes need enough sunlight to make the tomatoes grow better.

It is also necessary to ensure its temperature, if the temperature is lower than 15, the tomato will not be able to flower and pollinate normally. Do not let the temperature of the tomato be higher than 35, too high a temperature will also hinder its growth and reduce the yield of the tomato. In terms of soil selection, tomatoes do not have high soil requirements, but it is better to choose fertile soil.

Tomato roots need good air permeability, you can choose some soil with good air permeability for planting.

It is important to pay attention to the fruit management of tomatoes, and also to pay attention to temperature control. It is necessary to pay attention to the way of planting, the planting density, the management of the fruit, the prevention of diseases, the process and time of control, and the light.

Be sure to water properly, and also pay attention to the time of sunlight, do not expose to the sun for a long time, and pay attention to the proper use of fertilizer, be sure to prevent pests and diseases in advance.

Tomatoes are a common vegetable and are very easy to grow. Tomatoes are light-loving, fertilizer-loving, and water-hungry plants. Therefore, it is recommended to meet 6 hours of light per day when planting.

It can be planted without that much light, but the small tomatoes may not be sweet enough or grow poorly. Whether tomatoes are sweet or not is related to the type, but the most important thing is related to the amount of light and fertilizer, in order to grow delicious tomatoes, please give them a good light growing environment.

Planting

Seed germination is related to four external factors: temperature, humidity, light, and soil. Proposed to be planted during the Chinese New Year, the tomato is an annual herbaceous plant that is slightly tolerant to low temperatures. The germination temperature of small tomato seeds is 15-25 degrees.

Too cold or too hot will not sprout. If the temperature and humidity are good, it will germinate in 7-14 days, and there are also those that germinate in 3 weeks. Therefore, you need to be patient and wait, or think about whether you don't have the conditions needed for tomato seeds to germinate.

Indoor: February-March, Outdoor: March-April

Tomatoes need light to germinate: the seeds can be placed on the surface of the soil or covered with a layer of fine soil, the purpose is to fix, not to wash the seeds away with water. And don't block the light it needs to germinate.

How much and how often to water also depends on your environment, and it is difficult to regulate it for everyone. You just have to look at the soil. When the soil is seen to be dry, it can be watered, all at once.

Pinch the soil to see if there will be water squeezed out, when there is moisture, you can put it for a few days.

There is a mistake to put the nursery pot in the pot and store water in the pot. This is not recommended. In that way, the seeds are soaked in the soil without air, and they are easy to soak and rot.

The seeds used here, such as sweet peas, nasturtiums, and poppies, are forbidden. There are also some people who plant directly with garden soil or loess, indeed, they can be grown, but these soils have poor air permeability, and the effect of growing small tomatoes may not be ideal. If you really use these soils, you can add some breathable soil to improve.

Watering

Tomatoes are plants that need plenty of water. Sometimes there is a lot of soil, and the water requirements will be very high. In this way, to prevent less water at the roots, you can bury a plastic bottle on the main stem of the tomato while transplanting.

The bottles are full of holes. Filling plastic bottles with water will ensure that there is enough moisture at the roots of the tomatoes to keep them moist on hot summer days. It can't be too watery, but it can't be too wet or cold.

Therefore, it is still necessary to decide the amount and frequency of watering according to the situation. When the soil is dry, water again. Moreover, quantitative analysis of irrigation can prevent drought and waterlogging.

Irregular watering can also have an effect on the main stem, causing disease and exocarp cracking. Water the tip, not the leaves. Wet leaves can cause bacteria or ring disease.

Sowing amount: Generally, tomato seeds contain about 300 seeds per gram, and according to the planting density, the general amount of seeds per 667 square meters of field is 20-30 grams. 10-15 grams per square meter of seeding bed can be sown.

If the germination rate of seeds is less than 85%, the sowing rate should be increased appropriately. Land selection, squatting seedlings and seedlings, water and temperature control, skillful topdressing, topping, dipping, weeding, pest control, etc., only by careful every link, can we achieve a bumper yield and excellent yield of tomatoes. Here are two key tips to focus on.

Tomatoes are cultivated in different ways, so there are different pruning methods. Single-stem pruning is suitable for dense planting, 4000 trees can be planted in one acre, and the early yield is high. The pruning method is to keep only the main trunk and remove all the side branches.

The advantage of double-stem pruning is that saving the number of seedlings can better protect the underground temperature, so that the root system of tomatoes can grow better. If it's summer, you don't need to.

That is, use a brush or cotton ball dipped in a small amount of liquid medicine to wipe the flowers. Because 2,4-d is harmful to shoots and leaves, do not let the liquid contact with branches and leaves when using. 2. The concentration of tomatoline in the low temperature season is 35 40ppm, and 25 30ppm is appropriate at high temperature.

The use method adopts the spray flower method, and the phenomenon of cracking fruit often encountered in the planting process is mainly caused by more and less water; Rotten fruit may be diseased, and more often than not, it is easy to appear when it rains; Bird damage, whether it is a vegetable field, a rooftop or a small yard, there are birds eyeing tomatoes.

Spring Festival listing, sowing seedlings on September 10 of the lunar calendar, the temperature is about 18 to 28 degrees, the first flower of seedling cultivation can be watched, planted in the greenhouse, less watering to survive after the fruit is set before watering big water. Before and after the rain of land cultivation, I thought about the number of days of the variety, cultivated strong seedlings, and pushed forward. In the hometown of the Agricultural University, the planting of tomatoes is generally selected in April and August every year, before planting, the tomato seeds should be soaked in clean water for more than an hour, and then the water is filtered and then put into 50 degrees of warm water to continue to soak for about three or four hours, and the water is filtered for planting.

When planting tomatoes, you need to pay attention to the fact that you must control insect pests on tomatoes, and you must choose good varieties of tomato seeds, and you should also fertilize the land when planting tomatoes, and sprinkle some insect repellent drugs in the ground, and you should also ensure the humidity of tomato planting, and also ensure the temperature of planting tomatoes, these important things need to be paid attention to.

Ensure the soil quality of planting tomatoes, ensure that tomatoes can absorb sufficient nutrients, tomatoes need sufficient light, ensure that tomatoes absorb water resources, prevent the occurrence of insect pests, etc.

Before sowing, it is necessary to select high-quality seeds, which are mainly strong disease resistance and high germination rate. Control the amount of seeds according to the planting area, and use potassium permanganate and other solutions for seed dressing before sowing, and the time is controlled in about 10 minutes. Then take it out and soak it in warm water for about 5 hours.

Then take it out and wrap it in a damp cloth and put it in an environment of about 24 degrees for germination, and when most of the seeds are white, you can sow them. When sowing, the sowing time can be appropriately early, which can prolong the harvest period of cherry tomatoes, which is usually carried out around the Qingming Festival.

Using the ridge planting mode, the planting of tomatoes must be carried out on sunny days, pay attention to the row spacing of tomatoes, correctly cover the plastic film and choose the plastic film, and properly water the planting water.

When tomatoes are already 3-4 bunches of fruits, they are generally watered with fertilizer water, that is, they will be mixed with a little water-soluble fertilizer at the same time as watering, not compound fertilizer, top dressing is generally water-soluble fertilizer, water-soluble fertilizer is full of nutrition, fast dissolution, high absorption and utilization rate, which can meet the high nutritional needs of pepper growth period, which can not be done by conventional compound fertilizer, and water-soluble fertilizer is also in line with agricultural development, water and fertilizer integration, water and fertilizer saving.

Tomato moisture management.

Watering when planting, can maintain the balance of water, prevent the plant from dehydration and death, this watering requires more water, to ensure the penetration of the planting soil, planting in winter and spring, has been watered dark water as well, can prevent the ground temperature from dropping more, planting in summer and autumn, generally using watering water, watering water consumption is large, keep moist for a long time, is conducive to slowing down seedlings.

When spring tomatoes are planted, the seedlings are generally older, and they are generally no longer watered during the period from the time of slow seedling watering to the first ear of fruit sitting. The seedling age of summer and autumn tomato planting is small, after slowing the seedling, it is necessary to promote the rapid growth of seedlings, timely watering, and pay attention to cultivation after watering.

Flowering period of water control squatting seedlings, flowering rarely watered, unless the drought is serious, this period is mainly to keep the soil loose, the surface dry, promote strong seedlings, to ensure that the root system expands downward, for the future plant vigorous growth, lay a good foundation.

When the fruit water sits 2-3 in the first ear of fruit, it should be watered in time to promote the fruit, pay attention to the watering time, the water is watered early, and the plant will often grow vigorously, the vegetative growth will be too vigorous, and it is not easy to set the fruit or delay the fruit setting period. After the watering is completed, the growth of the plant is stunted, and although there are many fruit sets, the leaves become smaller, the growth is slow, and the yield is reduced.

Watering in the full fruit period is carried out after the first ear fruit sits, at this time the tomato has entered the stage of flowering and fruiting, fruit expansion and maturity, the plant growth is large, the organs of each part have a large demand for water, generally watering once in the early 5-6 days of fruiting, so that the ground is dry and wet, and shallow hoeing can be carried out after watering, otherwise continuous watering is easy to cause ground plate knots, and the evaporation is large.

Watering is done to keep the soil moist and meet the plant's need to absorb water. In addition, it can improve the air humidity between the ground and the plants, and around noon in dry weather, sprinkler irrigation or sprinkling water on the plants can be carried out when conditions permit, and potassium dihydrogen phosphate can be used with Ribery Yanwo powder to reduce the temperature of the foliar surface and reduce the occurrence of sunburn and virus diseases.

Sowing amount: generally 1 gram of tomato seeds with 300 grains, according to the relative density of transplanting, generally 20-30 grams per 667 square meters of street seeds. 10-15 grams per square metre of seeding bed.

If the seed emergence rate is less than 85%, the sowing rate should be increased accordingly. Site selection and seed selection. Squatting seedlings pre-seedling.

Drain water temperature controlled. Skillful fertilization. Take off the top and beat the branches.

Dip in flowers. Soil and weeds. Pest control, etc., only by paying attention to each stage can we complete the harvest and excellent yield of tomatoes.

Here are two important key points.

Tomatoes have different cultivation methods, so there will be different pruning methods. Self-pruning is suitable for sparse cultivation, 4,000 trees can be planted per acre, and the initial production is high. The pruning method is to save only the main stem and remove all the branches.

The advantage of double stem pruning is that the seedlings can be saved, and the ground temperature can be maintained faster, so that the tomato rhizome can grow and develop stronger. If it's summer, you don't have to.

That is, use a soft pen or cotton wool to dip a small amount of potion to wipe the flowers. Because 2,4-d is fertilizing young leaves and leaves, do not let the potion touch the branches when applying. 2.

The application temperature of tomato spirit is 35 40ppm at ultra-low temperature, and 25 30ppm at high temperature. The operation method is spray flower method, and there are rotten fruit conditions often encountered in the planting process, mainly due to the fact that the water is more and less; Rotten fruit is likely to have pests and diseases, and a large amount of precipitation will be prone to occur; Bird damage, whether it's a vegetable garden. On the rooftop or in the courtyard of Zhejiang, there are birds who are determined to get tomatoes.

On sale during the Spring Festival, sowing seedlings on September 10 of the lunar calendar, the temperature is around 18 to 28 degrees, the first petals of seedling cultivation can be seen, planted in the greenhouse, less watering after surviving before hanging fruit do not water flood. Around the time of the spring equinox cultivated on land, I thought about the number of days of the species, shaped the seedlings, and pushed forward. In the hometown of Agricultural University, the planting of tomatoes is generally selected in April and August of each year, and the tomato seeds should be soaked in cold water for more than an hour before planting, and then the water is filtered and then put into 50 degrees of boiling water to soak again for about three or four hours, and the water is filtered for planting.
