Management skills of greenhouse cultivation of garlic seedlings

After planting to the end of the knife, generally 3 water. The watering is based on the principle that the amount of water in the early stage is large and the amount of water in the later stage is smaller. The head water is 35 kg per square meter, and the seedling height is 6 to 9 cm, and the water is poured, 30 kg per square meter, and the first 3 days to 5 days before the pouring. Water, 20 kg per square meter. After cutting the head knife, cover the sand and pour the water again. Temperature before planting, the temperature change should be appropriate higher, 26 degrees Celsius to 28 degrees Celsius during the day, 18 degrees Celsius to 20 degrees Celsius at night; after emergence, 24 degrees Celsius to 25 degrees Celsius during the day, 16 degrees Celsius to 18 degrees Celsius at night, so that the garlic grows long Fast, long Qi. The temperature must not be too high, otherwise it will cause heat between the plants and cause decay. Generally, no top dressing is required during the growth period, but when the growth is affected by the lack of nitrogen fertilizer, the ferric ammonium can be applied in an amount of 15 kg to 20 kg. In order to promote the rapid growth of garlic seedlings, when the seedling height is 20 cm, it can be watered once with 0.5% ammonium nitrate water, and the dosage per acre is about 6 kg.
