Many vegetable farmers very much recognize the role of rooting agents. They believe that their rooting effect is good and their effect is fast. Therefore, no matter whether it is tray, watering or rooting, rooting agent will be added. However, the fact is that the premature aging of vegetables in recent years has a great relationship with the abuse of rooting agents. Tomatoes are only "long roots, no fruit" and are also related to rooting agents.
Recommendation: The main role of rooting agents is to take root, but who knows how many tomatoes are suitable? When the growth of vegetables is normal, the nutrient-type fertilization can meet the growth needs of vegetables. Rooting agents are not necessary. Instead, the plant growth regulators in the soil will be excessive, and the reproductive hormone balance in vegetables will be broken. It is more prone to various problems.
Misunderstanding 2: Flat cultivation
In order to save trouble, many growers use flat hoes to grow tomatoes. After planting, in order to control weeds, they are covered with black mulch, and agricultural operations such as flowering, spraying, and smearing are carried out on the mulch film. The mulch is close to the ground, and the farming operation and irrigation are in the same row, which leads to severe consolidation of the soil between the rows of tomatoes, hindering the exchange of gas between the soil and the air, reducing the vitality of the roots, affecting the absorption of carbohydrates by the roots, and the growth of the plants is weak. Slow.
Suggestion: The summer cultivation of tomato should be covered with high ridge or sorghum mulch, and the cockroach is generally made 20~25 cm high, and then covered with mulch. Sorghum mulching cultivation is not only conducive to water retention and fertilizer protection, but also beneficial to rainy season drainage, disease prevention and anti-aging. For the greenhouse that has been cultivated in flat sorghum, it can be combined with soil, and the heart can be changed into ridge back in 2 or 3 times to prevent excessive soiling, damage root system and reduce the ability to absorb nutrients. Pay attention to the way the film is covered, and use the iron wire, bamboo piece, etc. to support the film to increase the air flow on the soil surface, and the operation line is separated from the irrigation line.
Misunderstanding 3: Improper application of fruit-fruiting agent
Why are the tomatoes of the same panicle large and small? That is because the method of applying the fruit-fruiting agent is wrong. Some tomatoes have not yet blossomed, and the whole bouquet is sprayed at once. The fruit of the buds that are not open forms a stiff fruit. In the future, no matter what advanced fertilizer is used, it still cannot grow up.
Suggestion: Use the method of flowering, which one is open, to effectively avoid large and small fruit and increase the overall output.
