What should I pay attention to when growing tomatoes, and what should I pay attention to when growin

Grow tomatoes in pots at home, pay attention to these points, there will be endless tomatoes to eat in the future!

The planting method of tomatoes is as follows: 1. Prepare seeds: Prepare high-quality seeds, disinfect the seeds in advance, and soak them in water.

1. There are many varieties of tomatoes to prepare seeds, you can choose your favorite varieties and prepare full, full, healthy and high-quality seeds. Before sowing seeds, the seeds should be sterilized, wrapped in gauze, soaked in 50 water for 10 minutes, or can be soaked in 10% sodium phosphate solution for 20 minutes, and then the seeds should be cleaned, and then soaked in 30 warm water for 23 hours, which can promote the germination of seeds as soon as possible.

Second, the temperature suitable for the development of tomatoes is 24-26, which can be sown in spring, and can promote the germination of tomato seeds within the suitable temperature range. Prepare loose nutrient soil, sow the seeds evenly into the soil, cover with thin soil, maintain the moisture of the soil, wait for the seeds to take root and germinate, under normal maintenance, the seeds will germinate in about 3-4 days.

3. When the tomatoes grow two or three true leaves, they can be planted, and the ground temperature needs to be stable at more than 10 when planting, which can be conducive to root growth and improve the survival rate. Tomato seedlings are removed from the soil, carefully planted in the soil, sprinkled with appropriate water and kept in the sun.

Fourth, field managementTomatoes should be cultivated in time after planting, so as to promote rooting, promote slow seedling growth, and cooperate with cultivating loose soil weeding. Before planting, apply plantar fertilizer to the cultivation site, and appropriate topdressing can be done 1-2 times in the later growth period, and water immediately after fertilization. Watering needs to be adjusted according to seasonal climate change, and drainage measures should be taken during the rainy season.

Tomato cultivation techniquesDeep ploughing

Tomatoes are cultivated in thick, loose, fertile, well-drained soil. In order to promote the development trend of tomato rhizomes to depth, it is necessary to cultivate deeply; The ground is fast in winter, and it can be deeply cultivated 25 30cm before freezing, and it is not raked after turning, which is convenient for the soil regolith layer. Tomatoes can be cultivated with flat furrows or high furrows.

In the northern region, the mature cultivation of the more arid areas or the sparse height-width ratio is suitable for flat furrows, and the general furrow width is 8 10m long. In the southern region and the land with abundant water resources, high furrow cultivation should be selected.

Apply base fertilizer

Deep tillage should be combined with topdressing, generally 667m2 with organic fertilizer 5000 7500kg. At the same time as applying the base fertilizer, it is best to mix phosphate fertilizer with organic fertilizer, and apply 30 40kg of phosphate fertilizer per 667m2.

Planting time and relative density (after the planting period is clear, planting seedlings 60 to 70 days earlier).

The planting stage of spring tomatoes should be determined according to local climatic conditions. Generally, the average daily temperature is above 15, and the soil temperature is stable above 10. Seedlings are raised in the seedbed in mid-January and planted in mid-to-late March.

Cultivating

Soil cultivation should be carried out immediately after tomato planting to promote rapid hair and slow seedling growth and development. Soil cultivation should be carried out continuously 3 4 times, and the deep layer of soil cultivation is shallower than one time, and can be moderately cultivated, which can promote the stem tip to produce adventitious roots and expand the root group.

Top dressing

The liquid fertilizer management method is mainly based on base fertilizer, before the end of March, pay attention to the observation of growth and development of moderate top dressing, and avoid top dressing after the end of March.

Planting time

The suitable seedling age for spring tomato cultivation in the open field is 50-70 days, that is, planting should be carried out 50-70 days before planting. For example, in the area of Shenyang City, located at 41 north latitude, spring tomatoes are planted in the reserve in February, and planted in the open field after frost in early to mid-May.

Breed selection

Mature varieties with cold tolerance, dark light tolerance and strong disease resistance should be selected.

Picking

The harvest period of greenhouse spring tomatoes is accompanied by climatic conditions, temperature management methods, varieties are different and different, generally from full bloom to perfect fruit, mature varieties 40-50 days, medium ripening varieties 50-60 days, the fruit is set to white (white ripening period) can be carried out after human ripening, generally picked and sold in the fruit out of the bag.

If you want to plant tomatoes, then first of all, you must choose the soil with more fertile and wide soil when planting, and in the process of fertilization, you must use farmhouse fertilizer, do not use fertilizer bought outside, and often water the plants more, to prevent the occurrence of pests and diseases, if there are small insects, then you must spray insecticides in time. If you can do these things well, you will be able to grow tomatoes well.

First of all, it is necessary to choose the appropriate control temperature, the temperature must be grasped at about 20 degrees, we must pay attention to the soil when planting, we must choose high-quality seeds, we can also choose the way of spreading mulch film when planting, and we must strengthen water and fertilizer management.

When planting, pay attention to the weather, temperature, and whether the soil is nutritious, by the way, you should water and fertilize more, but also pay attention to spraying pesticides, pay attention to pruning branches, and pay attention to the conditions for tomato growth.

Tomatoes need to be grown in a loose and fertile soil, with good water permeability and air permeability, organic fertilizer can be added to the soil to enhance nutrients before planting, and disinfectant can be sprayed to prevent pests and diseases.

When planting tomatoes, pay attention to the seedlings do not water fertilizer first, if the small Ming period is easy to cause the seedlings to burn, wait until more than 10 cm and then add a small amount of fertilizer.

Tomatoes are grown as follows:

1. Seed treatment

Before planting, the seeds need to be soaked in warm water, which can not only break the dormancy of the seeds, promote germination, but also sterilize. The specific treatment method is to soak the seeds in water for 1-2 hours, and then put the seeds in warm water at 20-60 degrees Celsius, stirring constantly, keep the seeds in warm water for about 15 minutes, and then continue to soak for about 5 hours.

Second, the choice of soil

Tomatoes do not have particularly high requirements for the soil, they have a certain degree of fertility, which can be kept moist and loose. Tomatoes are moisture-loving plants, but they are not tolerant to waterlogging, so pay attention to drainage during the rainy season, and build drainage channels before planting. The width of each planting soil is best about 1m, and it is arranged in a rectangular arrangement to facilitate management and harvesting.

3. Sowing and planting

Once the seeds have been processed, they can be planted. After sowing, about 3-4 days can sprout, seedlings grow 2-3 true leaves can be planted, planting needs to seek the ground temperature above 10cm, and the temperature difference can not be too large. We also need to apply enough fertilizer when planting, and the topdressing time is slowly shortened as the tomatoes grow.

The first topdressing time should be in the flowering stage, and the second time in the growing period. After planting, a small amount of water should be watered to speed up the adaptation of new seedlings to the soil.

3. Sowing time

Sowing seeds at the right time is also an important condition for high yields, because there are many varieties of tomatoes now, so the planting time between different varieties and different regions is also different, and it should be implemented according to the specific local conditions.

4. Prune branches and leaves

There will be a lot of side branches in the growth process of tomatoes, these side branches will consume too much nutrients, resulting in very few high-quality tomatoes in the whole plant, so we need to make up for a part of the excess branches and leaves to prune off, only retain the main stem and a part of the side branches, and we also need to remove the denser leaves at the fruiting place, so that the whole plant can better photosynthesize, the permeability is also good, and the fruit is more excellent.

5. Prevention and control of diseases

Tomato early blight, also known as spotted disease, is round or nearly round and mainly harms the leaves of the plant. The prevention and treatment method is to ventilate in time, and if the disease has occurred, it is necessary to use drugs scientifically and rationally**. Late blight is a fungus that begins to darken the edges of the leaves and infects the stems and fruits, but the whole plant turns black.

**The method is also ventilation, and if the disease occurs, it is also sprayed with the corresponding drug in time.

6. Tomato harvesting

When the tomatoes bear fruit, it is necessary to keep the fruits well, remove all the deformed and weak fruits, and leave 4 to 5 fruits on each branch, and when the fruits are ripe, they should be harvested in a timely manner, and then packed separately according to the quality, and finally sold in a unified manner.
