Vegetable seedlings should be prevented early
Vegetable dead seedlings are a common occurrence in the process of vegetable cultivation. It is very troublesome to replant the seedlings after the vegetable has died. So, is there any way to prevent vegetable dead seedlings? This article will give you a detailed introduction to the causes and preventive measures of vegetable dead seedlings. There are five main reasons for the death of vegetable seedlings after seedlings. One is that the soil temperature of the seedling bed is too low, and the seedlings can not take root after the seedling bed is delayed, resulting in dead seedlings; the second is that the seedbed soil is mixed with unfertilized organic fertilizer unevenly. The roots are caused by dead roots; the third is that when the seedlings are seeded, the seedlings are too much, and at one time, the seedlings lose too much water, and the seedlings are not easy to recover and the dead seedlings; the fourth is that the seedlings are not well developed before the seedlings, and the roots are few; It is too late to seed, causing root damage, weak absorption and dead seedlings. In summary, the following comprehensive countermeasures should be taken to prevent and control the dead seedlings after vegetable seedlings: Improve the soil temperature of the seedbed and ensure the temperature requirements of the seedlings after seedlings. The temperature of the seedbed soil such as cucumber and eggplant is not lower than 16 °C, and the temperature of the seedbed soil such as cabbage is not lower than 8 °C. The organic fertilizer used in the seedbed soil must be fully fermented and decomposed, and carefully mixed with the bed soil. When dividing the seedlings, the bed soil should be compacted and leveled, then ditched, seeded, and watered. Then move into the nutrient bowl and the nutrients will be thoroughly poured. Don't hurt too many roots when starting a seedling, bring more perennial, follow the up, don't start too much seedlings. The seedlings are wrapped in a damp cloth. In case of excessive water loss. In the process of emergence, it is necessary to pick out seedlings with less roots, broken, sick and deformed. The seedlings should be small and should not be large, which is conducive to improving the survival rate. Generally, the first seedlings, the seedlings of the solanaceous fruit in the two leaves and one heart, the seedlings of the cabbage in the three leaves and one heart, the cucumber seedlings before the cotyledons are unfolded. The seedlings should be selected on a sunny day. For example, when the greenhouse light intensity is high, a grasshopper can be placed on the shed above the shelter to prevent direct sunlight from immediately dividing the seedlings.
