Tomato is a vegetable that many people like to eat, but for farmers, it is not easy to increase the yield of tomato. The problem is that the use of nitrogen and potassium fertilizer will cause tomato yield and quality. In order to grow tomatoes better and increase the yield of tomatoes, let's take a look at the fertilization skills of tomatoes!
Because in the process of tomato planting, many farmers have not been able to control the amount and use of potassium in potash, which leads to the use of potassium or the excessive use of potassium. Therefore, the quality of the tomato will also have problems. Potassium-deficient tomatoes generally show small plants, slow growth, small stems and very weak stems.
Potassium deficiency usually starts from the old leaves on the leaves of tomato. The edges of tomato leaves, especially the tips on the tip of the leaves, begin to appear yellow, and some brown patches appear, but the sides of the veins or the middle part of the leaves remain intact. The color, this is different from magnesium deficiency.
Reasons for potassium deficiency in tomato planting
One is that the partial application of nitrogen fertilizer by farmers inhibits the potassium deficiency caused by the absorption and utilization of potassium;
The second is because the temperature is too high, for example, the maximum temperature in the day is more than 35 degrees, or the temperature is too low. When the temperature is below 8 degrees in the evening, the root system of the tomato will be affected, thus affecting the absorption and utilization of potassium fertilizer;
The third is that many farmers pay less attention to the use of potash, and the amount of use is too small. It is almost difficult to find a potassium sulphate fertilizer in a farmer's shop. The dealers recommend potassium sulphate type compound fertilizer.
How to use potash properly in tomato
In the use of tomato base fertilizer, it is recommended to choose potassium sulfate fertilizer, remember not to use potassium chloride, introduced by professional growers, chloride ion damage to tomato roots, and affect the quality of tomato.
Tomato soil preparation
In the use of tomato base fertilizer, if the farmer uses more than 1000 kg of animal or straw fermented organic fertilizer per acre (667 square meters), 20 kg of potassium sulfate fertilizer can be applied.
The demand for potash fertilizer is very low before the start of the expansion of the tomato. The farmers can apply the 20-10-25 formula with the water when the earing fruit begins to expand and water, but not more than 5 kg per acre. Do not use more than 3 kg of viscous soil. After each watering, you can apply 15-10-25 of fertilization.
In summary, everyone must have a deeper understanding of the techniques of growing tomatoes, so if farmers want to increase the yield of tomatoes, they need to pay attention to the skills of fertilization, I hope this article is helpful to everyone.
