Tomato tendon and fruit to teach you three strokes to easily get
Recently, many vegetable farmers who planted summer tomatoes have shown that the tomato fruits are yellow and red, and there are black lines in the place where the yellow is developed. Some severe peels are hardened by the skin, and the inside of the fruit can be browned through the epidermis. From the description of the vegetable grower, this is a tomato rot fruit, which is a physiological problem, the most important manifestation is poor fruit coloration. Recently, the rot of the rotted fruit has a lot to do with the environment of the high temperature and strong light of the summer tomato. Therefore, in order to reduce the appearance of tendon and fruit, it is not necessary to start from improving cultivation conditions.
Shading should be moderate to avoid insufficient lighting
In order to reduce the temperature of the shed, many sheds are covered with sunshade nets, but many vegetable farmers are no longer in control after covering the sunshade nets. The sunshade nets cover all day, resulting in less light, less light, and rot disease. The rate is high. It is recommended that the shade nets should only be covered at noon on sunny days, and should be removed in time in the evening and rainy days to ensure the time and light intensity of the tomatoes.
Rational fertilization to avoid imbalance of nitrogen and potassium
When the tomato fruit enters the color-changing period, the nitrogen nutrient level in the plant is too high, which will affect the formation of lycopene, resulting in uneven color change and formation of tendon. In order to prevent premature aging of tomato in summer, many vegetable farmers are less likely to have nitrogen fertilizer, and the chance of producing rot fruit is greater. Therefore, when the tomato fruit is expanded, the high-potassium water-soluble fertilizer can be appropriately increased to reduce the application of the high-nitrogen fertilizer. It can also be sprayed with potassium dihydrogen phosphate 200-300 times to quickly replenish nutrients and reduce the chance of fruit rot in the later stage.
Raise the root system to avoid affecting the absorption of water and fertilizer
At present, the temperature is higher and the amount of water evaporation is larger. Some vegetable farmers over-watering in order to promote the rapid growth of tomato, resulting in root injury, which leads to a decrease in the ability of roots to absorb water and nutrients, and promotes the occurrence of tendon rot. It is recommended that the vegetable farmers reasonably water the water to avoid over-slipping water after the excessive drought, and avoid the high temperature period when watering. Combined with watering, functional products can be used to maintain the root system.
