Watering and fertilizing but hurting the roots? There are 2 common problems with growing tomatoes, and farmers should not make any more mistakes in gardening
Many growers ask, the tomato in the fruit, but there is a withered situation. Some people say it is because the plant is infected with the blight, do not know what the reason is. How can you avoid the problem of withered tomatoes when you plant them again this spring?
Tomato wilt disease will cause the plant wilt, generally in the flowering and fruiting period, the harm is greater, once occurred it is difficult to control. Tomato frium wilt is a disease that infects the root system. Watering and fertilizing is an essential management in the field, but these two aspects are also the most likely to cause problems, causing damage to the root system, resulting in tomato fruit wilt.
Problem 1: water too often
After the tomato planting, many friends worry about the soil drought, they continue to water. Especially now the temperature is high, transpiration, think need more water. What could go wrong if you water it too often?
Too much watering in the early stage of tomato can not only waste water, but also affect the growth of root system. Many of the greenhouse soil permeability is poor, water too much, there will be soil compaction. Tomato root can not absorb oxygen, will appear retting root situation. When the root of a tomato is damaged, the pathogen infects the plant from the wound, eventually causing the plant to wilt.
When the tomato grows the first ear fruit, it is the period of root growth, this period is not easy to too much water, appropriate drought a bit, conducive to rooting and fruit hanging. In addition, do not rely on the feeling when watering, to see the soil 10 cm of soil moisture, tomato growth appropriate humidity in 70% ~ 80% .
Problem 2: too much fertilizer
Many farmers believe that in order to produce a high yield of tomatoes, the more fertilizer the better, so each application of fertilizer is very large. Unreasonable fertilization methods, not only cause nutrient waste, nutrient deposition in the soil, and fertilizer concentration is too large, it will burn roots, resulting in plant wilt.
When applying fertilizer to tomato, we should adopt the method of applying thin fertilizer frequently, the fertilizer utilization rate is high, and will not harm the root system. In the past, when we plant and apply fertilizer, we used to follow how much catty of fertilizer per mu of land. Now we need to see the fertilizer concentration to determine the amount of fertilizer used. Before each application, check the concentration of fertilizer with EC pen.
For example, when the tomatoes are watered after the slow-growing seedlings, they need to take fertilizer. From this period until the first ear fruit grows, the EC value is controlled at this period to be 1.5. After the fruit expands, they need to increase the fertilizer concentration, different growth period requires different fertilizer concentration, control of fertilizer concentration, tomato can be high-yield.
When we grow tomatoes, watering and fertilizing are two very critical management, if the above two problems, the tomatoes are very easy to wilt after hanging fruit. Therefore, we should not only maintain an adequate supply of water and fertilizer, but also learn to control water and fertilizer in special times, so that tomato roots, leaves, flowers and fruits to normal growth.
