How many times do tomatoes need to be fertilized throughout the growing season? When did they take place? Tomato should be topdressed appropriately during the growth period, and nitrogen fertilizer should not be applied locally, but must be applied in combination with phosphorus and potassium fertilizer.

In general, after planting slow seedlings, fertilization is applied to promote the growth of stems and leaves. After the first panicle of the fruit begins to swell, a second top dressing is carried out to promote fruit expansion. Medium-late maturing varieties also require 3-4 topcoats after harvesting the first and second spikes.

Foliar sprays of superphosphate or potassium dihydrogen phosphate solution during fruit growth are beneficial to fruit ripening and increase yield. After planting slow seedlings, it is necessary to plow the ground to retain moisture. During the flowering of the first inflorescence, irrigation should be controlled to prevent flower and fruit drops due to overgrowth of stems and leaves.

The fertilization in the process of tomato growth can be roughly divided into two parts: one is to apply enough basal fertilizer, which is the basis of tomato growth. The key to whether tomatoes can ripen after transplanting is whether they are properly managed with water and fertilizer; The second is proper top dressing.

Attention should be paid to timely and appropriate top dressing. Tomatoes should be replenished with water and fertilizer in time during several critical periods of growth. The basic principle of tomato fertilization is to base fertilizer, supplemented by top dressing, and fertilize according to the actual needs of tomato growth, so as to avoid the problem of yellow leaves or excessive growth caused by excessive fertilization.

From the perspective of tomato growth stage, tomato fertilization requires the application of three kinds of fertilizers: one is less slow seedling fertilizer, that is, the stage when tomato seedlings are transplanted to the field. Generally, about 20 kg of urea can be applied, and slow seedling fertilizer can not be applied when the base fertilizer is sufficient; The second is to skillfully apply flower and fruit fertilizer.

Tomatoes need more fertilizer during flowering and fruit set. 60-90 kg of potassium sulfate compound fertilizer is applied per mu to meet the growth needs; Third, apply more fruit expansion fertilizer. When the tomato is expanded, it should be topdressed many times, and the principle of a small amount of times should be mastered.

During the flowering and fruiting period and the fruit expansion period, the demand for fertilizers is very high. Farmers need to carry out top dressing in combination with the fertilization of the land.

Fertilizing can greatly boost the growth of crops, but applying too much or too little fertilizer can cause problems with tomato growth. Tomato fertilization should master the following principles: First, tomato fertilization should be reasonable, do not blindly apply nitrogen fertilizer.

Excessive application of nitrogen fertilizer will lead to excessive growth or yellow leaves of tomatoes, which will affect the yield and quality of tomatoes. Secondly, tomato fertilization should increase the amount of organic fertilizer. The use of chemical fertilizers can cause soil problems. The application of organic fertilizer can increase the content of soil organic matter; Third, tomato fertilization should pay attention to the principle of combining water and fertilizer management.

Simple fertilization or watering will only have a negative effect on tomatoes.

At least three times are needed, including the fruit expansion stage, the flowering stage, and the growth period. During these periods, fertilizer must be applied in time, so as to ensure the yield.

To guarantee 3 to 5 times. After the ears are fruited, when they expand rapidly, during the peak fruiting period, these periods must be fertilized.

Tomato fruiting period on the use of imported high potassium water-soluble fertilizer, not only can promote the tomato fruit expansion, and the fruit expansion speed is fast, and the use of powder potassium dihydrogen phosphate, can speed up the tomato color speed, and can be evenly colored, good effect, and then spray imported chelated calcium magnesium fertilizer, can make the tomato surface clean and smooth.

Top dressing in the tomato fruiting period, after the first ear of fruit begins to be harvested, the fertilizer is good with fast-acting chemical fertilizer, when using water-saving drip irrigation equipment, it can be applied to Yanwo water-soluble fertilizer according to the mu, and the water is 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.

Raise tomatoes on the balcony, apply this "fertilizer", the soil is not compacted, and the tomatoes are hung all over the trees.

Fertilization of small tomatoes should be paid attention to the right time and appropriate amount. The so-called timely refers to the application of small tomatoes when needed, such as the discovery of small tomato leaves are light, when the plant growth is weak, fertilization is timely.

As for when to apply what fertilizer, it depends on the different growth and development stages of small 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 bud stage, more phosphorus and potassium fertilizers can be applied (chicken and fish offal, bone meal, bran ash: ash made from rice husk burning, 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.

The growth process of tomato cultivation is divided into:Five stages: After planting from tomato seeds, it will go throughGreen ripening period；And then to the backMicro-ripening period；Until the tomatoes start to turn from green to redSemi-ripe period；The fruit of the tomato will become hard and it will be therePeak ripening period；Finally, the tomato fruit reaches from hard to softMaturity period。Throughout the process, required:According to the growth trend of tomatoes, reasonable fertilization, as much phosphorus and potassium fertilizer as possible, which can make the fruit of the tomato swell and make the fruit more ruddy.

As we all know, tomatoes are favored by consumers in the market because of their slightly sweet taste and rich in vitamins. Many consumers buy it back and eat it raw, which is more conducive to the absorption of vitamins and can also play a role in whitening. It is precisely for this reason that many farmers in the market have begun to plant tomatoes, the key points of tomato planting are relatively simple, there are too many breakthroughs in technology, and the number of days of planting is relatively short, which is quite popular with farmers.

Tomato growth is mainly divided into five stages, the earliest is actually green ripe and slightly ripe. At the beginning of the green summer, that is, the tomato fruit officially grows, the fruit has become very large and firm, some of the inner flesh has shown a tendency to turn yellow, and the outer peel is also slightly white, which means that the tomato has successfully grown. Later, when the second period of micro-ripening has appeared, the color of the fruit on the surface of the tomato has appeared, and the top of the fruit has appeared, with a slight red halo, which is also called the top red fruit.

When the tomato grows about 80 to 90 days, it enters the third and fourth periods. The tomato fruits of these two periods also have different performances, in the semi-ripe period, most of the surface of the tomato fruit is red, which can also be called semi-red fruit, the texture of the tomato in this period is still relatively hard, and the taste is relatively jerky. Reaching the fourth stage is the ripening period, at this time, most of the surface of the tomato appears red, except for the shoulder, there is still some residual green, in India, the tomato still maintains a certain hardness, very hard to the touch.

From the first to the fourth stage, the tomato grows in a hard state until the fifth stage, which is the ripening stage, when the tomato fruit turns completely red and the surface is very soft to the touch. In these five periods, the corresponding growth needs to be fertilized, in the initial growth period, the tomato needs to be applied basal fertilizer, and so on tomato customization 7 to 10 days later, it is necessary to combine watering to apply rotten farmhouse fertilizer, and then wait until the second to the 30th period of fruit expansion, the medicine to apply expansion fertilizer to the tomato, to the middle and late stages of tomato growth, it is also necessary to spray the leaves with potassium dihydrogen sulfate solution to prevent pests and diseases.

All in all, the tomato should be fertilized during the five growth periods, and the surface color and texture of the tomato are constantly changing during the growth process, and the tomato becomes soft and has a red luster after the five growth periods, and it can be picked.

Tomato growth is divided into two stages, namely seedling period and flowering period, of which the seedling stage is mainly based on growth, germination and differentiation, and the flowering period is directly related to the growth and development of the plant and the yield in the future.

1.During the seedling period, we need to apply fertilizer more reasonably and scientifically, and control the proportion of nitrogen, phosphorus and potassium fertilizer, which is very important for cultivating high-quality strong seedlings and improving the flowering rate and fruiting rate. 2.

Before planting, we need to reapply basal fertilizer before tomato planting, so as to ensure that the crop has enough energy to grow. 3.Promote seedling fertilizer, after the completion of planting work, in about 12 to 15 days need to apply seedling fertilizer, seedling fertilizer can not be too thick, to be light and thin, combined with watering, 8-10 kg of urea per mu with water or shallow ditch, can also be watered on the water human manure urine 400-500 kg.

4.Fruit fertilizer, in the initial stage of tomato first ear fruit expansion, it is necessary to reapply 1 fruit promotion fertilizer, 12-15 kg of urea, 8-10 kg of potassium sulfate per mu combined with irrigation ditch, or 600-700 kg of manure and urine on water rot. When the first ear of tomato fruit is nearly ripe, that is, it enters the full fruit stage, and the amount of top dressing should be appropriately increased during this period, and 13-15 kg of urea, 9-10 kg of potassium sulfate can be applied in a shallow ditch per mu, or 700-800 kg of manure and urine with water decay.

The process of tomato growth includes flowering, fruiting, ripening and so on. Fertilization is required at least 3 or 4 times during the growth process. That's the only way to ensure production.

Tomatoes are a common vegetable. Fertilizing is an essential task in the process of growing tomatoes. However, there are certain techniques for fertilization.

Too much or too little fertilizer can lead to partial application or lack of nutrients in tomatoes. It directly affects the growth of tomatoes, leading to a decrease in quality. So, how should tomatoes be fertilized?

The following brings you high-yield fertilization methods for tomatoes;

1. Fertilizer demand: Tomatoes have a greater demand for nitrogen and potassium fertilizers, but not much demand for phosphate fertilizers. They prefer to grow in nutrient-rich soil.

The need for nitrogen will increase dramatically until the tomatoes are set, but after successful fruiting, the need for nitrogen will drop and a large amount of potassium will be required. Therefore, in the planting process, the amount of fertilizer should be adjusted according to the characteristics of tomato's demand for fertilizer, and according to the different growth stages of tomatoes. Avoid physiological deficiencies in tomatoes due to improper fertilization, which can affect the yield and quality of tomatoes.

2. Apply basal fertilizer: Before planting tomatoes, it is necessary not only to carry out land preparation, but also to apply enough basal fertilizer in the process of land preparation. The basic fertilizer is mainly the decomposed farmhouse fertilizer.

Sufficient basal fertilizer can ensure that tomato has sufficient nutrients throughout the growth period, and increasing the application of organic fertilizer can also effectively improve soil structure, increase particulate matter in the soil, increase soil softness, and ensure soil respiration. tomato roots, and create a good environment for the growth and development of suitable roots. Promotes healthy root growth and strong seedlings, and enhances plant resistance to stress.

3. Timely topdressing: Usually, when the basal fertilizer is sufficient, there is no need for topdressing during the period when the tomato is planted on the fruit. When the first fruits are gradually bulging, top dressing should be started in combination with watering.

Then, when the subsequent fruit swells, top dressing should be done and the amount of potassium fertilizer should be increased to ensure the normal growth and development of the tomato. It can also be equipped with the right amount of bio-bacterial fertilizer to promote root expansion and development and reduce the number of harmful bacteria. Prevents root diseases and various physiological problems, and increases the yield of tomatoes.

4. Spraying foliar fertilizer: Reasonable spraying of foliar fertilizer can prevent many problems of tomatoes, and it also has the effect of topdressing outside the roots. Some of the problems caused by nutrient deficiencies can be supplemented by spraying foliar fertilizers and supplementing the corresponding elements.

Proper application of foliar fertilizer can promote the differentiation of tomato flower buds, enhance tomato resistance, and prevent premature senescence of plants. And different foliar fertilizers can prevent different physiological diseases. For example, borax can prevent tomato plum fruit, while nucleotides can prevent yellow leaves.

Therefore, the application of foliar fertilizer is also more important in tomato fertilization.

The above is a brief introduction to the high-yield fertilization method of tomato. Although tomatoes have a strong growth capacity and high yields, they are relatively simple to grow, but they also need to be well managed in planting. Especially fertilization, where fertilizers are used to supplement the nutrients that are lacking in tomatoes.

If not properly fertilized, it will lead to insufficient nutrients or certain elements in tomatoes, which will affect the growth of tomatoes and reduce yield and quality.

Tomatoes have a greater demand for nitrogen and potassium fertilizers, and phosphate fertilizers have little demand, and like to grow in nutrient-rich soils, apply basal fertilizer Before planting tomatoes, it is necessary not only to do a good job of land preparation, but also to apply sufficient basal fertilizer when preparing the land.

Apply fertilizer four times, and when planting, apply fungus fertilizer to the hole.

Bacterial fertilizer can not only prevent the occurrence of root diseases, but also activate the soil, promote rooting, and regulate plant growth. This is an important step in cultivating tomato seedlings and laying the foundation for high yields in the later stage. ”

The conventional dosage of bacterial fertilizer per mu is 4-8 catties, which is evenly applied into each planting hole before planting, and mixed well with the soil.
