How do you grow tomatoes?

Seedling selection: choose a well-ventilated and sunny field with loose and fertile soil as a seedbed, and cover a greenhouse or do a good job of sunshine before sowing. Before sowing, the bottom water is thoroughly watered, and the seeds are dressed with a new high-fat film to prevent the spread of seed diseases.

It does not affect the function of germination and swelling, strengthens the respiration intensity, and improves the germination rate of seeds.

Land preparation and planting: select fields with drainage and irrigation, deep soil layer, and no bacterial wilt; After transplantation, the new high-lipid film should be sprayed in time to protect the aboveground moisture from evaporation, the seedling moisture from transpiration, isolate pests and diseases, shorten the seedling retardation period, and quickly adapt to the new environment.

Seedling management: After the seedling stage, it is necessary to set up a frame in time to tie the vine and prune it (the vine is moderately tight, and only one main branch is left), which can effectively ventilate and transmit light, reduce soil and air humidity, and prevent diseases caused by high humidity. It is necessary to strengthen the management of fertilizer and water, according to the growth process of the plant, it is necessary to apply fertilizer and irrigation in a timely and appropriate manner, keep the fertilizer moisture sufficient and reasonable, and spray a new high-lipid film to enhance the utilization rate of fertilizer efficiency, which can effectively prevent premature aging of plants and improve yield and quality.

Flower and fruit preservation: Tomatoes are prone to flower and fruit dropping under the influence of adverse environmental conditions, which affects early ripening and yield. The measures of flower and fruit preservation are respectively in the bud stage, young fruit stage and fruit expansion stage, spraying vegetable fruit strong tiling, which can thicken the fruit pedicle, increase the amount of nutrient delivery, prevent flower fall, improve pollination capacity, improve fruit setting rate, and speed up the expansion speed.

Take a look at the Funong website, where you have all the knowledge you need to grow tomatoes.

1. Tomatoes should be planted on ridges.

Ridge planting can concentrate a large amount of live soil on the ridge surface, improve the air permeability of the soil, and can quickly rent and change the roots and return to seedlings, avoid the occurrence of root diseases in the middle and late stages of tomatoes, and if it is planted in the open field, it can also avoid flood irrigation caused by heavy rain and damage to the roots. It is recommended that the ridge surface of the grower be set at 70 cm wide, the ridge height should be 10 cm high, and the upper part of the furrow should be 40 cm wide.

2. Grasp the row spacing of tomatoes.

Tomatoes are planted on both sides of the ridge surface, generally about 2900 trees are planted per mu, and the plant spacing is controlled at about 35 cm.

Planting tomatoes must be placed on sunny days to change the rows, after the end of planting, if conditions permit, shade treatment should be carried out for 2-3 days to prevent tomato dehydration.

3. How to properly cover the plastic film and choose the plastic film.

The main function of mulching film is to increase the ground temperature, control weeds, if watering under the film in winter can reduce the humidity in the shed in winter, and there is also a silver-gray mulch film can prevent insect pests to a certain extent.

It is recommended to use white mulch film for tomatoes with overwintering stubble, which can play a role in raising ground temperature, and black mulch can be used for tomatoes with overwintering stubble, which can play a role in preventing weeds from growing.

4. How to scientifically water planting water.

Planting water, also known as root water, is the first water to be watered after tomato planting, so farmers must water it thoroughly this time. In addition, farmers are not recommended to use nitrogen, phosphorus and potassium fertilizers when watering, otherwise it is easy to cause tomatoes to grow vigorously in the seedling stage, but at this time, farmers can rush to apply rooting and humic acid fertilizers, which can promote the rapid rooting of tomatoes and achieve the purpose of strong root system.

1. Prepare seeds: Prepare high-quality seeds, disinfect and soak the seeds in advance.

2. Sowing seedlings: Tomatoes can be sown in spring, prepare loose nutrient soil, and sow the seeds evenly into the soil, which can germinate in about 3-4 days.

3. Planting: When the tomatoes have grown two or three true leaves, plant them carefully in the soil.

4. Pastoral management: After the tomatoes are planted, they should be cultivated in time, loosened and weeded, and topdressed and watered appropriately.

1. When sowing seedlings, the land needs to be watered thoroughly, and after the soil is slightly dry, sowing is carried out, and after sowing, the surface is covered with a centimeter of soil (before planting, the seeds need to be soaked in warm water of 50 55 for 10 to 12 hours, and the seeds are sown directly in the land after being taken out, generally 10 to 15 cm to sow a seed).

2. When the tomato seedlings grow 3 to 4 leaves, you can dig out the seedlings, pay attention not to hurt the root system when digging, keep some soil at the roots of the seedlings, and then plant them directly into the soil, straighten the plants, and then water them until they are watered thoroughly.

3. Tomatoes should be watered once when planting, water thoroughly, and then water every 3 to 5 days. Tomatoes need to be watered under control before they bear fruit, and after the tomatoes are fruitful, just keep the soil moist.

4. After planting in the ground, you need to water fertilizer once every 10 days, and apply rotten chicken manure, sheep manure, and pig manure before flowering. Proper removal of freshly grown shoots can promote flowering and fruiting.

5. The time of pruning and pruning is when the tomato seedlings are higher than 80 cm, it is necessary to top and remove the leaves at the top, because the bearing weight of tomato branches and seedlings is limited, and the results will be overwhelmed and lodging, in order to ensure the quality and shape of the fruit, it is necessary to prune and prune.
