1. The vegetables should pay attention to the weather when they raise seedlings. To separate the seedlings, choose sunny weather. If the greenhouse is strong and the temperature is high, put a straw curtain or cover the shade net at a distance above the shed set in the greenhouse. Avoid direct sunlight just after the seedlings, resulting in water loss, wilting, serious dead seedlings missing.
2. When the vegetables are raised, they should pay attention to the seedlings. When the seedlings are divided, the seedlings will be excessive once, and the seedlings will lose too much water after one minute; the seedlings will not be easy to recover after the seedlings are divided; the seedlings will not develop well before the seedlings, and the roots will be less. Sub-seedlings are too late, causing rooting, weakening absorptive capacity and dead seedlings. Remove the seedlings with a damp cloth to prevent excessive water loss. In the process of raising seedlings, the seedlings with fewer roots, broken leaves, sensible and deformed seeds should also be picked; when the seedlings are divided, the seedlings should not be large, which is beneficial to increase the survival rate. Usually the first time the seedlings were divided, when the seedlings of the eggplant were in two leaves, the seedlings of the cabbage were in one leaf and the seedlings of the cucumber were before the cotyledon was unfolded.
3. Pay attention to the sensation when vegetables are raised. The vegetables should be planted when the soil is dry and wet to facilitate the survival of the seedlings. The protective vegetable seedlings shall be covered with mulch after the planting, so as to keep warm and protect the seedlings. The day before planting, the seedbed or nutrient bowl should be irrigated so that the soil can be transplanted without damaging the roots. Preventive measures: Do not overshoot the roots when lifting, and bring more soil.
