Tomatoes have just been made into one year old fruits, what kind of fertilizer should be rushed?

Hello, tomato gangzao is recommended to rush to apply Ribery Yanwo water-soluble fertilizer.

1. Management of seedlings before setting fruits.

After planting, the tomato is still in the stage of high temperature and strong light. Therefore, in management, attention should be paid to ventilation and light transmission, shading and cooling, and preventing pests and diseases. After the tomato seedlings are slowed down, the seedlings are squatted, and the seedlings are generally no longer watered, and the ground is sticky and cultivated in time 2 to promote the rooting and strengthening of the seedlings.

Second, the middle and late stage of field management.

1. Temperature management: The weather gradually becomes cold after fruit setting, so it is necessary to focus on heat preservation and scientifically regulate the temperature.

In order to promote the ripening of the fruit after the full fruit period, the temperature should be higher, mainly to maintain the night temperature of about 15 to promote the formation of lycopene. By the end of October, the minimum temperature in the shed at night does not reach 10, and the curtain should be covered in time to keep warm. In order to ensure that the light is removed as early as possible on the basis of heat preservation, cover the straw curtain at night.

In addition, it should be noted that when the light is weak on a cloudy day, the temperature in the shed during the day should be 3-5 lower than the normal temperature, and the reflective curtain should be hung in time.

2. Fertilizer and water management: when the first ear fruit grows to the size of walnut, end the squatting seedlings, water fertilizer once, and use 8-10 kg of high potassium special fertilizer per mu, or 3-5 kg of water-soluble fertilizer with a large number of elements in Ribery Yanwo per mu, so as to facilitate the rapid expansion of the fruit, and water it once in about 10 days or so.

When the third ear fruit is expanded, the amount of fertilizer is appropriately increased than the first time, and at the same time, 800 times the liquid plant root activation conditioner is applied per mu to increase the ground temperature and activate the soil, promote root growth and prevent premature aging. Winter watering to see the sky to see the seedlings, cloudy days do not water, avoid flood irrigation, into December the fruit has matured, generally no longer watering in case the ground temperature drops, the humidity in the shed is too large and easy to affect the maturity. After each watering, it is necessary to ventilate and drain moisture in time.

3. Dipping flowers and preserving fruits: most of the time it is necessary to take hormone treatment. Because of the poor environment (high temperature, low temperature) and poor crop growth, it must be treated with hormones to achieve the purpose of preserving flowers and fruits.

4. Timely thinning flowers and fruits, autumn and winter tomatoes generally only leave 3-4 fruits, and each fruit leaves 3-4 fruits, which is conducive to the growth of fruits and fruits.

5. Strengthen the prevention and control of pests and diseases, and use carbendazim or chlorothalonil spray to prevent diseases before watering in winter.

6. Other matters: tie vines and prune in time.

7. Strengthen the light, the natural light is weak in winter, and it is important to take measures to improve the light in the greenhouse

Planting friends shared that the whole process of tomato planting uses hypertrophic and fat two complete intelligent nutrient solution, and the size of tomato fruits is uniform and there are no secondary fruits.

At this time, you should use some foliar fertilizer to promote growth, and you can also add some. Plant growth regulators to increase fruit set....

Flush the balanced suspended carb water-soluble fertilizer, the carbon source I used before!

After the tomato bears fruit, it can be applied with a fertilizer containing potassium, diluted with water and applied to the roots of the plant, and it can also be sprayed with superphosphate or potassium dihydrogen phosphate solution as foliar fertilizer, generally every 10 days or so to apply fertilizer, fertilization to master the principle of thin fertilizer diligent application.

How to fertilize tomatoes after they bear fruit.

1. Apply potassium fertilizer.

Tomato needs sufficient nutrients to grow after hanging fruit, at this time it is necessary to apply potassium fertilizer to promote the expansion of its fruit, dilute the fertilizer containing potassium in a certain proportion, and apply it to the roots of tomato plants, at this time it is necessary to apply less nitrogen fertilizer, otherwise it will adversely affect its fruit.

2. Apply foliar fertilizer.

After the tomato bears fruit, it can also be applied foliar fertilizer, such as spraying superphosphate or potassium dihydrogen phosphate solution, which is conducive to the ripening of tomato fruits, and can also improve the yield of tomato fruits, and can also add some calcium, boron and manganese during the fruit-hanging period. Zinc. molybdenum and other trace elements.

3. The number of fertilization.

Tomatoes should be fertilized frequently after fruiting, and tomatoes of late-maturing varieties need to be in the first.

1. After the harvest of the second ear fruit, 3-4 times of top dressing, so as to meet the nutrients required for the growth of tomatoes, generally every 10 days or so, it is not advisable to apply fertilizer for a long time, so as to avoid poor growth of tomatoes.

4. Precautions.

When fertilizing tomatoes, you need to master the principle of thin fertilizer diligently, you can not apply thick fertilizer to it, so as not to cause fertilizer damage due to excess fertilizer, and raw fertilizer can not be applied.

The first top dressing is when the first ear fruit begins to expand to the size of a walnut, and nitrogen fertilizer is the main thing to speed up the expansion and growth of the first ear fruit (when the first ear fruit begins to expand, combined with watering, top dressing "fruit promotion fertilizer", this time the amount of fertilizer generally accounts for 30 40% of the total fertilizer. ）

The second topdressing is when the first ear fruit is about to be harvested, and the second ear fruit is expanded to the size of a walnut, which is also mainly nitrogen fertilizer, and an appropriate amount of phosphorus and potassium fertilizer is applied;

The third top dressing is after the harvest of the second ear fruit, with sufficient Bika water-soluble fertilizer as the main fertilizer, with an appropriate amount of phosphorus and potassium foliar fertilizer (when the first ear fruit is partially ripe, each.

When the second and third spikes of fruit enter the rapid expansion period, the demand for fertilizer and water reaches the peak, and it is necessary to chase "fruit fertilizer". ）

Generally, apply enough organic fertilizer before planting, and then you can leave it without fertilization.

The life cycle of tomatoes is divided into three stages: germination, seedling and flowering and fruiting.

Germination period. From seed germination to cotyledons, until the first true leaf is revealed, it is the germination stage.

Seedling stage. From the appearance of the true leaves to the budding of the first inflorescence, this period is a parallel period of vegetative growth and reproductive growth.

Flowering and fruiting period. From the first inflorescence budding to the completion of fruit harvesting, it is divided into the first flowering and fruiting period and the peak flowering and fruiting period. The flowering and fruiting stage is a transition stage from the first inflorescence budding to fruit set, which is mainly vegetative growth to reproductive growth. The peak flowering and fruiting period is from the first inflorescence to the completion of fruit harvesting, which is the main period for yield formation.

The nutrient uptake of tomatoes increases as the growth period progresses. The nutrient absorption is small in the early growth stage, and the nutrient absorption increases rapidly from the first inflorescence, and the nutrient absorption can account for 70 80 of the total absorption at the peak fruit stage.

The uptake of nitrogen, phosphorus and potassium in tomato showed a linear upward trend, the absorption of potassium was nearly twice that of nitrogen, and the absorption of calcium was similar to that of nitrogen.

The fertilization techniques for tomatoes are:

Basal fertilizer: Tomatoes should be reapplied in the open field, that is, on the basis of applying organic fertilizer, 35 40 kg of phosphorus and potassium nitrate fertilizer should be applied at the bottom of each mu.

Top dressing is combined with watering when the first ear is enlarged, 20 kg of nitrate phosphorus fertilizer per mu is applied, and 20 kg of nitrate phosphate fertilizer per mu is applied as fruit fertilizer after the first ear is harvested. In the peak fruit stage, the mixture of 20 nitrate phosphorus fertilizer, 1 potassium dihydrogen phosphate, zinc sulfate and boric acid can be sprayed every 7 10 days, which can significantly improve the yield and vitamin C content in Xihong City.

Summary. Spray 2-3 times in a row, every 7 days at intervals.

Hello, tomato in any period is in need of a balance of water-soluble spike fertilizer, because nitrogen, phosphorus and potassium are necessary elements for crop growth, such as the fruit expansion period, if you blindly apply high potassium water-soluble mountain fertilizer, excessive potassium, it will also cause a series of problems such as small tomato withered fruit, poor sales, and many diseases, if you add balanced water-soluble fertilizer, this problem will not occur.

If I can help you, please give me a thumbs up, thank you How old is Pengguo?

The period between fruit setting and fruit setting when the grains grow to the size of soybeans and when the fruits are ripe.

Peng is best several times.

Spray 2-3 times in a row, every 7 days at intervals.

Tomato seedlings need to be fertilized when transplanted alive. At the seedling stage, nitrogen, phosphorus and potassium (20 20 20) water-soluble fertilizer plus humic acid active liquid fertilizer or amino acid active liquid and slag fertilizer plus biological bacterial fertilizer were applied to the roots. Foliar sprays of natural brassinin plus humic acid active liquid fertilizer plus potassium dihydrogen phosphate.

Every 7 to 10 days, 2 to 3 times in a row. In order to promote the roots to take root and strengthen the roots, promote the seedlings to grow seedlings and strengthen the seedlings. At the flowering and fruiting stage, the roots were flushed with nitrogen, phosphorus and potassium (20 20 20) water-soluble fertilizer plus potassium sulfate, or potassium nitrate plus potassium dihydrogen phosphate, and foliar spray potassium dihydrogen phosphate plus natural brassinin plus humic acid active liquid fertilizer, or Xingpeng phosphorus and potassium No. 1 plus sodium compound nitrate plus amino acid active liquid fertilizer, once every 7 10 days, 2 3 times in a row.

Hello, tomatoes need to balance water-soluble fertilizer at any time, because nitrogen, phosphorus and potassium are essential elements for crop growth, such as the fruit expansion period, if you blindly apply high potassium water-soluble fertilizer, excessive potassium will also cause a series of problems such as small tomato fruits, poor sales, and many diseases, if you add balanced water-soluble fertilizer, this problem will not occur.

Under the premise of applying enough organic bottom fertilizer, we must pay attention to the coordination of the three elements when topdressing, we must pay attention to the topdressing of phosphate fertilizer and potassium fertilizer, control the use of nitrogen fertilizer, too much will make the plant grow, you can use Yanwo potassium dihydrogen phosphate, with the advantage of "three seconds instant", the introduction of foreign double technology, so that potassium dihydrogen phosphate can be better absorbed by tomatoes, and Yanwo potassium dihydrogen phosphate can also achieve a wang control effect. The occurrence of diseases should be combined with watering when topdressing, otherwise it is not only not easy to be absorbed by the plant, but also easy to cause fertilizer damage.

When topdressing, attention should be paid to the frequent application of less and many times, in the amount of fertilizer, take the principle of less at both ends and more in the middle, and try to be timely and reasonable. Generally, attention should be paid to the following topdressing, seedling fertilizer, in order to make the newly planted plants can immediately get sufficient nutrients, only for seedling growth. Generally, 15 kg of ammonium sulfate or 7-8 kg of urea, or 15 kg of ammonium bicarbonate should be applied per mu before watering the tree water or slow seedling water, and it should be watered in time after top dressing.

Fruit-promoting fertilizer, generally in the first ear of fruit has expanded, the second ear of fruit sitting, the purpose is to promote fruit expansion, conducive to the growth of stems and leaves, topdressing Yanwo water-soluble fertilizer 30-35 kg, topdressing after watering.

Top dressing in the full fruit period, after the first ear of fruit begins to be harvested, the fertilizer is good for fast-acting chemical fertilizer, when using water-saving drip irrigation equipment, it can be applied according to the mu of Yanwo water-soluble fertilizer, and applied to the field with water through fertilization and irrigation. Foliar top dressing, tomato leaves have the function of absorbing a variety of nutrients, so spraying various fertilizers on the tomato foliar surface not only absorbs the speed, but also can make up for the lack of soil fertilization, and the effect is also very good.

This method is especially suitable for the application of trace element fertilizer, and the application effect shows that the application of extra-root topdressing on tomato can not only significantly increase yield, but also promote early maturity, delay senescence, and prolong the growth period and harvest period. There are many types of root topdressing applications, which can be selected according to the needs of application, and trace elements such as Yanwo potassium dihydrogen phosphate and Yanwo calcium and magnesium fertilizer can be sprayed.

Spring stubble tomatoes are in the fruit expansion stage, and have entered the peak period of nutrient demand for fruit growth and development, ensuring adequate nutrition** is the top priority of tomato fruit expansion management.

Nitrogen fertilizer is the main fertilizer, and potassium fertilizer is appropriately increased.

Top dressing during the rapid expansion of fruits: This topdressing is mainly to accelerate the rapid expansion of fruits and improve the expansion rate of fruit cells. To increase yields, overcome the body of the tree"Big and small years", which plays an important role in promoting flower bud differentiation.

This period is carried out on the basis of the second top dressing, after physiological fruit drop. The type of fertilizer is still mainly nitrogen, and the combination of phosphorus and potassium is the most ideal. According to the survey, the rapid expansion period (peak growth) of apple fruits varies depending on the region and variety.

According to the survey conducted by Tianjin Forestry and Fruit Research Institute, the peak growth of Marshal short-branched varieties and Golden Crown varieties occurred from mid-to-late June to early to mid-July. That is, after mid-June, the fruit will enter the period of rapid expansion. In production practice, top dressing should master the principle of topdressing and fertilizing according to the place, the strength of the tree, the number of fruits, and the demand for nutrients are also different.

The amount of fruit is large, and weak trees should be eaten"Partial rice", to give more fertilizer. For strong trees, trees with few flowers and fruits or young and vigorous trees that do not bear fruit, in order to slow down the growth of branches and leaves, promote the formation of short branches and the differentiation of flower buds, top dressing should be done after the new shoots stop growing, and the amount should be small. Right"Big year"Trees should be increased in the middle and late stages of top dressing.

Little years"Trees should focus on top dressing before and after germination. It should be noted that the middle and late topdressing of fruit trees should not be too late. The number should not be too much.

In order to avoid causing the growth of new shoots in late autumn, reduce the nutrient accumulation level and cold resistance of the tree. It also affects the coloration and fruit quality of the variety. Depending on the topdressing, the soil conditions of the orchard are different, and the topdressing should also be treated differently.

The fertilizer and water retention capacity of the sandy land is poor, so it is necessary to chase less frequently, and do not water a lot of water after the top dressing, so as to cause water and fertilizer leakage in tin. Saline-alkali land, the available phosphorus content in the soil is low, and phosphorus fertilizer should be added (soil application or extra-root topdressing) when topdressing.

Potash, pay attention to the amount of watering and the frequency of watering.

You can buy a fertilizer called tomato fertilizer.

This is the peak time when plants need fertilizer. It is necessary to use nitrogen, phosphorus and potassium compound fertilizer for plants, especially in the winter when the temperature is relatively low, and the ternary compound fertilizer and water-soluble fertilizer can be applied together. During the fruit-setting period, an appropriate amount of puffing fertilizer should be applied.

2. How to fertilize tomatoes in winter.

Be sure to pay attention to the amount of fertilizer applied in winter to avoid injury to the roots of the plant if the fertilizer is too much. When watering the plants in winter, the surface temperature drops, which affects the development of roots. Therefore, in winter, you can add an appropriate amount of humic acid fertilizer when fertilizing.

After application, it can play a good role in relieving the plant's root system to absorb nutrients well when the temperature is low. Liquid fertilizers can also be used to increase the surface temperature, promote plant growth and increase yields.
