In the process of high temperature seedling raising in summer, in order to avoid emergence of tall seedlings (legitimate seedlings), seedlings are required to take measures to regulate their growth, so as to achieve the standard of seedlings and seedlings. However, if the seedlings are excessive, there will be aging seedlings (stuck seedlings). After the aging seedlings are planted, the seedlings will be slow and the initial yield is low. Here, we remind farmers that there is no excessive control. So, how should vegetables be seedlings? The author suggests that in addition to regulating the temperature and fertilizer, may wish to use the following two strokes (take tomato seedlings as an example).
Move the plug to remove the root method Tomato when using the plug seedlings, the seedlings grow about 20 days, the roots will be tied down from the bottom of the plug hole, can be manually moved to achieve the purpose of root control seedlings. The law is used once every 5-7 days and it works well. In addition, if the density of the hole points used is relatively large, such as 105 points, the seedlings can be expanded (move into the 72 points of the plug) to prevent the seedlings from crowding each other to form a tall foot seedling.
One of the drug control methods is to spray high-concentration love and control seedlings. When the tomato seedlings have three leaves and one heart, use 10 ml of love to receive 15 kilograms of water to spray a controller. After sub-seedling, if there are signs of prosperous growth, 20 ml of love can be used to spray 15 kg of water once more. The second is to spray the assistant director of the powerful booster. With 10 ml of auxiliaries, half a bucket of water is sprayed once every 10-15 days, and sprayed twice a day during tomato nursery. The tomato seedlings will neither grow nor overgrow.
