What fertilizer is good to use after transplanting tomatoes?

Tomato transplanting period, to root and strengthen the leaves, promote the application of nitrogen fertilizer, promote the application of phosphorus fertilizer, young fruit expansion of potassium fertilizer, so tomato transplanting should not only take root, but also to strengthen the seedlings, so that the early stage should be based on nitrogen, phosphorus, potassium three elements, with microbial agents to regulate the soil, can effectively prevent tomato due to improper transplanting, poor roots, dead seedlings and other physiological problems, serious impact on the later yield. Well, tomatoes need fertilizer characteristics! What kind of fertilizer is used to root tomatoes quickly?

Let's take a look at the analysis below.

Tomato fertilizer characteristics.

The first is to apply sufficient base fertilizer, which is the basis for tomato growth, and the key to whether tomatoes can mature after transplanting to the field is whether the water and fertilizer management is appropriate;

The second is the appropriate amount of top dressing, top dressing needs to pay attention to the right amount of time, tomato in several critical periods of growth to timely replenish water and fertilizer. The basic principle of tomato fertilization is to focus on basal fertilizer and supplemented by top dressing, and carry out fertilization work guided by the actual needs of tomato growth to avoid excessive fertilization leading to yellow leaves or long growth.

What kind of fertilizer is used to root tomatoes quickly?

In the early stage, nitrogen and phosphorus fertilizer should be appropriately supplemented, seedlings and flower promoters should be formed, but nitrogen fertilizer should not be excessive, otherwise it will normally cause flower and fruit drop, or flowers and fruits, vigorous growth, etc., fertilizer should not be excessive, a small amount of meals can make crops better absorbed, and it is not easy to cause soil compaction; Therefore, after tomato transplanting, 5 kg of 10,000 mu of tillage balance of a large number of elements water-soluble fertilizer + 10,000 mu of microbial agent 1 barrel, the fertilizer effect is long-lasting, full of stamina, can promote root growth, increase white roots, improve the survival rate, reduce dead seedlings, it is recommended to drench 2 times after transplanting, with an interval of 7-10 days, slow seedlings quickly, more white roots, and more branches; It can be combined with the leaves of Shuobei, and the leaves can be evenly sprayed 1-2 times before and after the leaves to improve photosynthesis, promote the growth of leaves, raise seedlings and strengthen seedlings, and the leaves are thick and shiny.

Hello, after transplanting tomatoes, we should pay attention to the right time and the right amount. The so-called timely refers to the application of tomatoes when needed, such as the discovery of tomato leaves become light, plant growth is weak, fertilization is timely.

As for when to apply what fertilizer, it depends on the different growth and development stages of tomatoes, such as the seedling stage, you can apply more nitrogen fertilizer, (rotted human urine manure, soybean cake fertilizer, sesame cake fertilizer) to promote the rapid and robust growth of seedlings; During the budding period, you can apply more phosphorus and potassium fertilizers (chicken and fish offal, bone meal, bran ash: ash formed after the burning of rice husks, containing potassium) to promote the growth of flowers and seeds; Proper control of fertilization at the early stage of fruit setting is conducive to fruit setting.

No matter what period of fertilization should pay attention to the appropriate amount, if too much nitrogen fertilizer is applied, it is easy to form a long growth; Excessive application of potassium fertilizer hinders fertility and affects flowering and fruiting.

Planting tomato seedlings can be put compound fertilizer.

Tomato fertilization method

1. Bottom fertilizer. Growing vegetables is the same, and you need to apply organic stool first chain fertilizer. Organic fertilizer generally has chicken manure, cow manure, sheep manure, pig manure, etc., it is recommended to choose well-rotted sheep manure, sheep manure contains 24 to 27% organic matter, nitrogen (N) to, phosphorus (P2O5) to, potassium (K2O) to.

The organic matter content of sheep manure is more than that of other animal manure, which is a hot fertilizer. The nitrogen content is also the highest among these fertilizers, and there are also some trace elements. It is recommended that you use sheep manure about 2 to 3 square meters per mu, and the release of organic fertilizer is a relatively slow process, which takes about three years to be completely released, but in order to be able to continue to use, organic fertilizer needs to be applied every year.

In addition to organic fertilizer, the bottom fertilizer also needs to apply a large number of elemental fertilizers, and it is recommended that you apply urea about 15 kg per mu. It is best to use superphosphate for phosphate fertilizer, because it not only contains 16% available phosphorus, but also a part of calcium, because tomato has the first demand for potassium fertilizer and the second for calcium, so the choice of superphosphate not only supplements phosphorus but also calcium. 50 kg of superphosphate can be used for one acre of land.

Potassium fertilizer is generally potassium sulfate, 20 to 30 kg of 53% potassium sulfate per mu, 10 kg of phosphoric acid and 500 grams of compound trace elements per mu are used in combination, and the bottom fertilizer is basically OK.

2. Seedling topdressing.

When the tomato seedlings grow to 5 to 6 leaves, it is necessary to see if the tomato leaves are lightened, and if they are light, you can choose foliar fertilizer for spraying. It can be sprayed once every 10 days or so during the seedling growth period. In addition, when spraying foliar fertilizer, some insecticidal drugs and growth regulators can be compounded, which can not only control insect pests, but also improve fertilizer utilization rate.

3. Top dressing during the fruiting period.

When the tomato bears fruit, the top dressing is the most critical in this period, and it is also the time when the top dressing is more frequent, basically every time you water it. When the diameter of the first ear fruit grows to 1 5 to 2 5 cm, it is recommended to apply 15 to 20 kg of organic fertilizer, 20 to 30 kg of superphosphate or 5 kg of urea and 10 to 20 kg of potassium sulfate compound fertilizer per mu. When the second and third ears grow to a diameter of 3 cm, they should be watered, and basically these two periods are watered every 7 days.

10 kg of urea and 15 to 20 kg of potassium sulfate compound fertilizer per mu each time. When the fruit is at full fruit, it can be combined with spraying compound growth regulator for root topdressing, which is conducive to the improvement of fruit coloring and quality.

Tomatoes can be planted with compound chemical fertilizers, applied to the soil and then planted tomatoes, in the tomato growth period, need to apply thin fertilizer frequently, in order to promote the growth of its branches and leaves, it is the flowering and fruiting period, you can increase the appropriate amount of phosphorus and potassium fertilizer, pay attention to the fertilization can not be returned to apply thick fertilizer, and can not be partial to apply nitrogen fertilizer.

1. Compound chemical fertilizer

When tomatoes are planted, compound fertilizers can be applied to them, and they can be applied to the soil when planting, which can increase the fertility of the soil, so that tomatoes can grow more vigorously, pay attention not to apply fertilizer that is not rotten, otherwise the heat generated by fertilizer fermentation in the soil will burn the root system of the plant.

2. Fertilization during the growth period

The growth of tomatoes needs sufficient nutrients, when it grows, it also needs to be fertilized, generally 5-6 days after planting can be applied to it once nitrogen fertilizer, to promote the growth of its branches and leaves, the amount of fertilizer to apply 2-3 kg per mu can be, pay attention not to apply thick fertilizer, so as not to produce fertilizer damage.

3. Fertilization during the flowering and fruiting period

Tomatoes also need to be fertilized during the flowering and fruiting stage, and the first ear of fruit is observed to be whitish.

When the second and third ears of fruit swells rapidly, it can be topdressed 2-3 times, and then it is also necessary to supplement phosphorus and potassium fertilizer, which can promote the growth of its fruit.

4. Precautions

When fertilizing tomatoes, it is best to apply more organic fertilizer, the amount of chemical fertilizer should not be too much, and fertilization should master the principle of thin fertilizer diligently, each fertilization can be combined with irrigation, but also pay attention to not partial nitrogen fertilizer, otherwise excessive nitrogen fertilizer is not conducive to its fruit growth.

In the process of tomato growth and development, the demand for fertilizer is not very large, but tomatoes need nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, but at the same time, some trace element fertilizers are also needed, including boron, calcium, sulfur needs, so when planting tomatoes, we must pay attention to the uniform fertilization of these trace elements, but the demand for nitrogen fertilizer in tomatoes is still relatively large, so the application of nitrogen fertilizer can be appropriately increased when planting.

It should also be noted that the bottom fertilizer is also more important in the fertilization process of tomatoes. The base fertilizer is generally based on commercial organic fertilizer or farmhouse fertilizer, which can improve the soil and increase the permeability of the soil. According to the different raw materials, the normal dosage of 800 100 catties per mu of land is better.

Most of the farm manure is based on rice husk and chicken manure, and it is normal to use 5 8 square meters of one acre of land.

There are two ways to fertilize tomatoes. The first is to add fertilizer directly to the soil and wait for the soil to digest the fertilizer and deliver it to the roots of the tomatoes; The second is to mix fertilizer and water evenly and water it in the soil, or spray it on the tomato leaves to make the plant grow more vigorously.

When fertilizing tomatoes, you need to pay attention to the amount of fertilizer to avoid fertilizer damage to the plants. If the tomatoes are provided with too many nutrients, they need to be poured into the soil immediately to dilute the fertilizer content in the soil, and at the same time, the tomatoes need to be regularly loosened to drain the excess water from the soil and allow the plants to grow healthily.

Farmhouse organic fertilizer. Due to the long growth period of tomatoes, the growth of stems, leaves, and fruits is large, and more fertilizers are needed, mainly nitrogen, phosphorus, and potassium. However, in order to improve the yield and quality, we must pay attention to the use of organic fertilizers, a combination of organic and inorganic, mainly organic fertilizers, supplemented by lead fertilizers.

First of all, we need to know what fertilizers and elements are needed for the growth of this plant, which are very suitable for their growth. In the process of growth, in fact, their demand for nitrogen, phosphorus, potassium and other elements is relatively large. The biggest thing is to plant nitrogen and potassium fertilizers in the reserve, and tomatoes should pay more attention to the use of fertilizer.

I think tomatoes grow healthy, and the base fertilizer should be done well. It is best to use more well-rotted organic fertilizer or farmhouse fertilizer, and add an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer. Reasonable base fertilizer can make the tomato root system developed, tomato is very adaptable to the soil, and the pH value is the best in slightly acidic, fertile and deep soil.

Tomato has the most potassium demand for soil nutrients, followed by nitrogen and the least phosphorus, but phosphorus is very important for the development of flowers and fruits, so tomato should properly control water and fertilizer in the early stage to avoid growing too fast. When the first ear blooms, sprinkle a small amount of flowering water, and apply an appropriate amount of phosphorus-containing water-soluble fertilizer with the water to make the plant grow vigorously. The use of human feces is often controversial.

Some people wonder how dirty excrement can be used as fertilizer for imported tomatoes, and it's uncomfortable to think about it. Actually, these are all imaginary. In real life, especially in rural areas, fertilization is indeed a key to growing high-yielding, delicious tomatoes.

In my opinion, to fertilize tomatoes, we should mainly use organic fertilizers from farms, such as rotting grass and potassium fertilizer, farm toilet grass, dry chicken manure, etc. If you use flower fertilizer, choose a compound fertilizer rich in nitrogen, phosphorus and potassium. The soil is fertile and rich in humus, and the tomatoes grown are not only good for the plant, but also good for the taste.

But there are very few lands that naturally have this property, which is generally achieved through fertilization; All kinds of manure in the countryside are farmhouse manure that contains a lot of humus.

Hello! Tomato topdressing can choose to use fertilizers rich in phosphorus and potassium, such as diammonium phosphate, potassium sulfate, etc. In the process of top dressing, fertilizer should be prepared according to the plant growth stage, for example, in the early stage of growth, diammonium phosphate should be used as the main top dressing, which is conducive to promoting root growth and fruit development; In the fruit ripening stage, top dressing with potassium sulfate is the main fertilizer, which is conducive to improving fruit quality.

The time of top dressing is generally carried out after watering, chasing once every 7-10 days, and burying auspicious to avoid too much fertilizer and too much concentration, causing problems such as wilting of plants or deformation of fruits. In addition to top dressing, attention should also be paid to the timely application of organic fertilizers for tomatoes, such as well-rotted compost, chicken manure, etc., which helps to improve soil fertility and soil structure, promote plant growth and fruit yield. It should be noted that the fertilizer should be avoided from directly touching the plant during the fertilization process, so as not to burn the roots and leaves, and at the same time, the appropriate soil moisture should be maintained to avoid fertilizer loss and waste.
