Hello everyone, I am a farmer. Cherry tomatoes, also known as small tomatoes, are not only simple to grow, but also can continue to flower and bear fruit throughout the year, with a long growth period and high yield. Because of its exquisite and cute appearance, high sugar content, sweet and delicious taste, unique flavor, it is very popular with consumers, the market prospect is good, and more and more people are planting. But some growers will find that the cherry tomatoes they grow do not know why the taste is not good, the yield is low, and there will be a lot of zombie fruits. Cherry tomatoes are a fertile crop that requires a lot of fertilizer. Therefore, if your tomatoes are of poor quality, there is a high probability that the fertilizer is not applied correctly or in place. Today, Lao Wang will give you a careful explanation of the main points, methods and precautions for fertilization of cherry tomatoes.
<h1 class= "pgc-h-arrow-right" > the fertilization characteristics of cherry tomatoes</h1>
If you want to fertilize well, you must first know how much fat the cherry tomatoes need and what fertilizer they need. Experienced farmers know that fruit trees consume a lot of nutrients when they bear fruit. Then since the cherry tomato is a continuous flowering fruit, correspondingly, the entire growth period needs to absorb a lot of nutrients from the soil. Therefore, if you want to grow high-quality cherry tomatoes, you need not only to apply sufficient base fertilizer, but also to multi-fertilize, including soil topdressing and foliar topdressing. The principle of fertilization is based on base fertilizer, supplemented by topdressing. Heavy application of high-quality decomposed organic fertilizer is the mainstay, supplemented by inorganic fertilizer.
In the growth of cherry tomatoes, there are 3 most important inorganic elements, potassium, nitrogen and phosphorus. Among them, potassium is the most important for fruit quality, and the potassium absorption of cherry tomatoes at the fruit setting stage and fruit expansion stage accounts for more than 70% of the total potassium absorption in the whole growth period, and the demand for it is only slightly reduced until the late harvest stage. Nitrogen fertilizer is the highlight of the seedling stage, accounting for more than 50% of the total demand of the three elements, which is the premise of ensuring robust and good growth. Phosphorus is not in high demand throughout the growth period of cherry tomatoes, but it cannot be lacking, and it can assist in the better absorption of nutrients by cherry tomatoes. In order to ensure the balance of elements, it is also necessary to apply some calcium and boron fertilizers.

The fertilization of the cherry tomatoes grasps one trick: one base fertilizer, two topdressing fertilizer, and three attentions. The principle of topdressing is: from less to more, from thin to concentrated, mainly nitrogen in the early stage, and phosphorus and potassium in the later stage. Dilute manure water and fertilizer are applied alternately.
A base fertilizer: before the cherry tomato colonization, apply 5000-6000 kg of high-quality decomposed farm manure or organic fertilizer per mu, and cooperate with the application of inorganic fertilizer: urea 50 kg, calcium superphosphate 30-60 kg, potassium sulfate 40-50 kg. You can also directly choose the compound fertilizer on the market, the dosage is 100-150 kg. When applying, it is necessary to mix organic fertilizer and inorganic fertilizer as much as possible and then apply it into the planting soil to achieve soil and fertilizer blending.
Second topdressing: The topdressing of cherry tomatoes should be based on soil topdressing, supplemented by foliar topdressing, so I call it "two topdressing". Generally, the first topdressing is carried out when the first spike begins to expand, when the root system has a strong ability to absorb nutrients, and the nutrient supply is very important, which is also the key topdressing period of the cherry tomato. Compound fertilizer can be applied per acre with water 20-30 kg or urea 12-13 kg and potassium sulfate 12 kg.
The second fattening of the cherry tomato is when the first ear is about to be harvested and the second ear is expanded. At this time, the small tomato enters the fruit for a long time, and the amount of fertilizer should be large, otherwise it is easy to fall flowers and fruits. Special attention should be paid to the application of phosphorus, potassium fertilizers and trace element fertilizers. Compound fertilizers of 25-30 kg or equivalent amounts of urea and potassium sulfate can be applied per mu with water. After this topdressing, it must be watered enough so that the fertilizer effect can be fully utilized. After that, according to the growth of the plant, it is necessary to increase the number of topdressing, if the growth of the plant is weak, it is necessary to apply 20-25 kg of special fertilizer per mu per mu when the panicle fruit is about to be harvested and the panicle fruit in the next stage is expanded.
In addition, cherry tomatoes not only absorb nutrients from the soil from the roots, but also absorb mineral nutrients from the leaves to promote the development of fruits and seeds. Therefore, during the growth of the fruit, especially during the continuous rain in the early stage, when the soil topdressing cannot be carried out, 2 to 3 times foliar fertilizer should be sprayed, and 300-500 times the biochemical organic liquid fertilizer can be sprayed, and 500 times the chelated multi-compound micro fertilizer can also be sprayed to improve the quality of the cherry tomato.
Three notes: There are 3 precautions for cherry tomato fertilization.
1. Fertilization temperature: Try to avoid fertilization under high temperature conditions. At high temperatures, the amount of water evaporated from the leaves of the cherry tomatoes is large, which will affect the fertilizer efficiency. Therefore, it is best not to fertilize in the high temperature at noon, and it is advisable to use it in the early morning or evening.
2. Soil moisture: Try not to fertilize in the case of wet soil, which is easy to cause physiological diseases such as falling flowers, leaves and fruits.
3. Finally, the early topdressing should not be too much, and the result should be heavy fertilizer later. Too much fertilizer in the early stage, it is easy to make the plant grow, but it competes for the nutrients needed for the results, and it is easy to produce fertilizer damage.
<h1 class="pgc-h-arrow-right" > concluding remarks:</h1>
In the late growth stage of cherry tomatoes, the function of the root system of the plant to absorb nutrients and the function of the leaves to produce nutrients will be seriously degraded, resulting in plant malnutrition, limited nutrition is intercepted by the fruit that develops first, and the remaining tail flowers are stunted to become "motherless children", which is easy to produce zombie fruits. In order to avoid this situation, it is recommended to supplement foliar fertilizers in time in the later stage, including amino acids and micro fertilizers.
