How to grow tomatoes? What fertilizer is needed for a good tomato yield?

To make tomato yield, heat preservation and disease prevention is the foundation, fertilizer management in the application of nitrogen fertilizer on the basis of the application of phosphorus and potassium fertilizer to increase the application of phosphorus and potassium fertilizer, in addition to tomato calcium demand is large, but also to increase the application of calcium fertilizer.

After slowing down the seedlings, it is necessary to control the watering and squatting seedlings, and cultivate them when the moisture is suitable to promote root growth, lay the foundation for high yield, and eradicate weeds at the same time. And spray vegetable fruit Zhuang Tiling to enhance the quality of pollen fertilization of fruit and vegetables, strong cycle fruit setting rate, promote fruit development, no deformity, no empty shell, no seeds, good uniformity, improve quality, and make vegetables and fruits produce abundantly. Adopt the method of "balanced fertilization" and the principle of "eat less and eat more" to avoid single application of nitrogen fertilizer and excessive amount of fertilizer at one time, especially to ensure the adequacy of potassium fertilizer**.

Tomatoes have a long growth period, stems, leaves and fruits, and have a lot of demand for fertilizers, mainly nitrogen, phosphorus and potassium, but in order to increase yield and quality, we must pay attention to the use of organic fertilizers, and combine organic and inorganic, organic fertilizers are the mainstay, supplemented by chemical fertilizers. First of all, we have to understand what fertilizers are needed in the growth of this plant, what kind of elements are very suitable for their growth, in the growth process, in fact, they have a relatively large demand for nitrogen, phosphorus and potassium these elements, the biggest is that nitrogen fertilizer and potassium fertilizer are cultivated in protected areas are planted continuously, and the fertilizer of tomatoes should be paid more attention to. If you want tomatoes to grow healthily, you should do a good job of base fertilizer.

It is best to use well-rotted organic fertilizer or farm manure, add an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer, and a reasonable base fertilizer can be a developed tomato root system.

Tomatoes are very adaptable to the soil, and a slightly acidic, fertile and deep soil with a pH of 6 is best. Tomatoes need the most potassium for soil nutrients, followed by nitrogen, and the least phosphorus, but phosphorus is very important for the development of flowers and fruits. The first spike blooms, small watering of flowering water, and an appropriate amount of phosphorus-containing water-soluble fertilizer is applied with water to make the plant grow strong.

There are often controversies when using human feces and urine, and some people will think about how the tomatoes in the mouth can be used as fertilizer with dirty excrement, and they will feel uncomfortable thinking about it, but in fact, these are their own imaginations, and in real life, especially in the countryside today, if you want to grow tomatoes with high yields and delicious taste, fertilization is indeed a key. I think that the fertilization of tomatoes should be based on farmhouse organic fertilizer, such as rotted grass potassium fertilizer, farm toilet thatch, dry chicken manure, etc., if you use flower fertilizer, you should choose a compound fertilizer rich in nitrogen, phosphorus and potassium The soil is fertile and rich in humus, and the growing tomatoes are not only good plants, but also have a good taste of tomatoes; There are very few lands that naturally have such characteristics, and they are generally achieved through fertilization; All kinds of manure in the countryside are farmhouse manure that contains a lot of humus.

It is best to use potassium fertilizer to grow this crop, so that the fruit will be more red when the nutrition is more sufficient, and nitrogen fertilizer should be increased to increase the yield.

When growing tomatoes at home, such as in small vegetable gardens or potted plants, it is suitable to use organic fertilizers as base fertilizers, such as well-rotted animal manure, so that the vegetables grown are greener. When planting tomatoes in the earth, the main pursuit is high yield, and foliar fertilizers can be applied during the tomato growth period, such as potassium dihydrogen phosphate, and liquid fertilizers can be applied during the tomato growth period, such as diammonium phosphate, potassium phosphate, ternary compound fertilizer, etc. To improve yield, it is necessary to ensure temperature, water and fertilizer management, topping, thinning vegetables and fruits, and controlling insect pests.

Tomatoes have the highest absorption of phosphorus in the early stage of their growth, and the amount of phosphorus absorbed by the plant almost reaches the peak when the first ear grows to the size of a walnut, so we should ensure the ** of phosphorus in the seedling period of tomatoes and the growth period after planting, so as not to affect the differentiation of flower buds.

1. Use foliar fertilizer Kunlun wind to improve photosynthesis function, reduce leaf transpiration, promote root development and robustness, improve nutrient absorption function, and play a role in enhancing drought resistance, preventing lodging and increasing yield. 2. Tomatoes are a crop with a long growth cycle and fruiting period, so there is a large demand for fertilizer. In addition to the application of sufficient basal fertilizer, there should also be sufficient top dressing.

After the tomato is planted, nitrogen, phosphorus and potassium compound fertilizer should be applied every 8 to 10 days, and it should be noted that nitrogen fertilizer should not be applied too much.

In the process of growth and development, tomato has little demand for fertilizer, but tomato needs three kinds of fertilizer, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, and some trace element fertilizers, including boron, calcium, and sulfur. Therefore, when planting tomatoes, we must pay attention to the uniform fertilization of these trace elements, but the demand for nitrogen fertilizer is still relatively large, so the amount of nitrogen fertilizer can be appropriately increased when planting tomatoes. During the growth period, especially in the germination stage, the demand for phosphate fertilizer increases, so that tomato can obtain better bud differentiation effect and tomato seedlings can absorb more phosphorus fertilizer.

Therefore, when applying basal fertilizer, you must remember to add phosphate fertilizer. After the tomatoes germinate, growers begin to spray potassium dihydrogen phosphate on the tomatoes. It is important to know that there is a high demand for potassium during the tomato fruit stage, so you need to add enough potassium and compound fertilizer when fertilizing.

Tomatoes are a particularly susceptible crop to pests and diseases, so prevention should be started at an early stage. When planting and transplanting tomatoes, a liquid inoculant is mixed with water and root water is poured over the tomato roots. It can significantly promote the development of tomato roots, improve the survival rate, kill harmful bacteria in the soil, reduce the occurrence of soil-borne diseases, and enhance the ability to resist heavy cropping.

Heavy application of strong fruit fertilizer, tomato will enter the fruit setting period. Irrigate or drip irrigation with high-potassium water-soluble fertilizer 3-4 times per mu. It can reasonably supplement potassium, calcium and other elements to significantly improve the yield and quality of tomatoes.

Tomato continuous cropping is prohibited, and reasonable crop rotation is conducive to high yield, otherwise diseases are prone to occur.

Tomato cultivation should choose plots with high terrain, deep soil layer, loose and fertile soil, good drainage, sufficient sunlight and moderate pH, which can not only reduce diseases, but also make full use of soil fertility, increase yield and increase growers' income. The planting density of tomato can be determined according to different varieties, planting methods and the whole plant, and the row spacing can be determined according to local conditions. After dense planting, it is necessary to strengthen drainage and irrigation management, improve ventilation and light transmission between tomato sheds, prevent and control diseases and pests, and give full play to the yield increase effect of dense planting.

The suitable sowing date can be determined according to factors such as planting season, climatic conditions, planting methods and seedling facilities. The planting depth should be based on the absence of cotyledons. After planting, the right amount of soil can make the seedlings take root and grow quickly, preventing soil compaction.

Eliminate weeds in the field, eliminate breeding grounds for pathogenic bacteria, and reduce diseases.

In the process of growth and development, tomatoes do not have a large demand for fertilizers, but tomatoes need three kinds of fertilizers: nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer, but they also need some trace element fertilizers, including boron, calcium, and sulfur. Therefore, when planting tomatoes, we must pay attention to the uniform fertilization of these trace elements. During the growth period, especially during the germination period, the demand for phosphorus fertilizer increases, so that the tomato can obtain better bud differentiation effect and allow tomato seedlings to absorb more phosphorus fertilizer.

Therefore, when applying basal fertilizer, you must remember to add phosphate fertilizer.

Fertilization techniques for tomatoes:

In fertilization, the reasonable ratio of nitrogen, phosphorus and potassium is 1:1:2, 3000-5000 kg of decomposed organic fertilizer is applied per mu, 25 kg of superphosphate is applied, and 20 kg of potassium fertilizer (or 80 kg of plant ash) is applied.

Tomato should be topdressed appropriately during the growth period, and nitrogen fertilizer should not be applied partially, but with phosphorus and potassium fertilizer. Generally, seedling fertilizer is applied after planting to promote the growth of stems and leaves. After the first ear fruit begins to expand, the second top dressing is carried out to promote the fruit expansion, and the middle and late maturing varieties still need to be in the first.

After the first and second ears are harvested, top dressing is carried out 3-4 times.

Foliar topdressing with superphosphate or potassium dihydrogen phosphate solution during fruit growth is conducive to fruit ripening and increased yield. After planting and slowing down the seedlings, it is necessary to cultivate and protect moisture, and irrigation should be controlled during the flowering period of the first inflorescence to prevent flower and fruit drop caused by excessive growth of stems and leaves. After the first ear of fruit set, the plant needs more water and should be irrigated in time.

Pay attention to drainage during the rainy season.

Extended Information: Tomato cultivation techniques:

1. Temperature. From sowing to the appearance of the first true leaf (broken heart). Under normal temperature conditions, this period is 7-9 days; The seedling stage refers to the appearance of the first true leaf to the budding of the first inflorescence. The suitable daytime temperature is 25-28 and the night temperature is 13-17.

At this stage, the ground temperature has a great impact on the growth of seedlings, and the appropriate ground temperature should be kept at 22-23. The first flowering and fruiting period refers to the period from the first inflorescence budding to the fruit. This stage is the transition period of tomato from vegetative growth to reproductive growth and vegetative growth, which is directly related to the formation and yield of product organs.

2. Choose the time. Early maturing cultivation in southeast Guizhou is sown in mid to late November, seedlings are sown in mid to late December for regular season cultivation in other places, and seedlings are sown in mid to late May for late cultivation in autumn.

3. Soil. Tomatoes can tolerate drought, but not waterlogging, and the soil requirements are not very strict, in order to obtain high yields, it is necessary to choose a deep soil layer, loose and fertile, and strong water and fertility retention.

4. Colonization. Timely planting, reasonable dense planting: early cultivation in spring protected areas from late February to early March, planting in cold tail and warm weather; The open-field mulching was planted around March 20 in the cold tail and warm weather. The planting density is 50 30 cm between the rows of early-maturing varieties and the spacing between the rows is 50 30 cm, and the plants are about 3000 plants per mu. The medium and late maturing varieties are single-stem pruning, and about 3500 plants per mu are used; When double-stem pruning is adopted, about 2000 plants per mu.

5. Pruning. Pruning, racking, vine tying: build a "herringbone" frame after the first ear of fruit and fruit. There are two main ways of pruning, one is to leave only the main trunk, and all the side branches are removed (it is advisable to remove the side branches when they grow to 4-7 cm) is called single-stem pruning; The other is to leave the side branches under the first inflorescence in addition to the main stem, and remove all the other side branches, which is called double-stem pruning.

No matter what kind of pruning method is used, it is necessary to pay attention to tying vines in time.

It is good to use compound fertilizer, because this fertilizer contains all the nutrients needed by tomato plants, and can be combined in a unified way.

This is also one of the misconceptions that many farmers have about vegetable fertilizers, which should be fertilized according to the different growth stages of vegetables. If we have already planted tomatoes and want to have high yields, we need to know the fertilizer requirements of tomatoes. Tomato growth has a large amount of nitrogen at the seedling stage, and the demand for nitrogen, phosphorus and potassium increases when the first panicle begins to bear fruit, and potassium is required in the later stage of tomato growth.

Compound fertilizers can be used before the growth period, but after the fruit comes out, potassium increases, and high potassium fertilizers should be the mainstay. The compound fertilizer contains 17 potassium, which is difficult to meet the swelling of the fruit, so there are problems of uneven discoloration, small fruit, and poor taste. We must pay attention to fertilization during the planting process.

It's not that the more fertilizer is used, the higher the yield.

There are also various types of potash fertilizers. For example, potassium sulfate, potassium chloride, potassium nitrate, potassium dihydrogen phosphate, etc. How should farmer friends choose when planting vegetables?

These four fertilizers cannot simply say that they are good, and it can be said that how to use them well in other periods can be used to invest less and achieve many purposes. In general, many vegetables or fruits are sensitive to chloride ions, so try not to use fertilizers that contain potassium chloride or chloride ions. It is best to use potassium dihydrogen phosphate before flowering tomatoes.

It can mainly promote flower bud differentiation. The general usage of potassium dihydrogen phosphate is a foliar spray, which is absorbed through the leaves and has a good effect. It is best not to use potassium dihydrogen phosphate and calcium fertilizer at the same time.

It should be noted that with precipitation, the effect will disappear.

Potassium nitrate is best rinsed after the tomato has swelled, but do not use potassium nitrate after it has changed color. Because potassium nitrate contains nitrate nitrogen, it is easy to produce asphalt if it is used in the future, and the taste may not meet expectations. In the water supply management, when the tomato enters the flowering and fruiting stage, the water and fertilizer are sufficient and stable, and the soil moisture that is most favorable to the development of tomato fruit is about 80% 85%, and the first ear of tomato is about 1 cm long to ensure that the subsequent water is stable and sufficient.

It is recommended to carry out watering at 8-10 o'clock in the morning on a sunny day, and the best way to water is sprinkler irrigation, drip irrigation, irrigation under the film, watering in the morning and evening, and frequent watering. In summer, when the heat and drought are insufficient, emergency moisturizing can also be carried out by watering the "horse racing water", but it cannot be watered or filled with water at noon.

In fertilizer management, when the tomato enters the flowering and fruiting stage, the first autumn rain generally sits on the No. 1 panicle, when the milk fruit begins to grow larger, the second autumn rain is generally after the No. 1 panicle is ripe, and when the fruit set of the No. 2 panicle begins to expand, the autumn rain is carried out every 10-15 days, or every harvest, the autumn rain can be carried out an autumn rain, and the autumn rain is dominated by phosphorus and potassium. In addition, in order to promote better, more and higher quality flowering and expanding fruit of tomato, it is recommended to spray 2-3 times continuously with potassium dihydrogen phosphate, borax or boric acid solution, chelated calcium or amino acid calcium, zinc sulfate, tundrolide, chitin, amino acids and other foliar fertilizers during the fruiting of tomato.

A more nutrient-dense fertilizer should be used, as this is the only way to better help the tomato grow.

You should choose some compound fertilizers and organic fertilizers, so that the nutrients of the plants can be more sufficient, and you should also do a good job of watering, and you should also fertilize according to the proportion.
