Onions are a common vegetable that is resistant to transportation and storage. Onion cultivation management is easy, and the economic benefit is between 1000 and 2000 yuan per mu. Experiments have shown that nurturing strong seedlings is the key measure to increase production. Strengthening onion seedling technology management is the key to improving onion yield and improving onion quality. First, a reasonable fertilization Fifth, spraying fertilizer We provide wide range of herb tea cut, like echinacea tea, nettle leaf tea, dandelion root tea, valerian root tea and red raspberry leaf tea. We can provide blend herbal tea according to formula of customer and we also provide formula according to needs of customers.

In fertilization, we must apply enough base fertilizer to ensure that seedlings do not need to be top-dressed. When the seedlings grow to 15-20 cm in height, combine irrigation with topdressing urea, and apply potassium dihydrogen phosphate 10 days before planting to a concentration of 0.2-0.4. %. Seedbed soil should be selected for loose fertility, be able to keep it moist, and have not been planted with onions and garlic within 3-5 years.
Second, pouring sole water
According to many years of experience of vegetable farmers, wet sowing of onion seedlings is better than dry seeding. Bottom water filling, irrigation depth of not less than 6 cm, to meet the needs of onion emergence, halfway irrigation to make the seedbed hardened, unfavorable to the healthy growth of whole seedlings and onions.
Third, timely sowing
Onion sowing must be adapted to local conditions, sowing too early, seedling growth is too fast, easy to bolting in advance, thus affecting yield; seeding too late, seedlings are susceptible to malnutrition, the yield per plant is low, the suitable temperature for the growth of onion seedlings in the nursery process is 12 -20°C.
Fourth, timely shade
After the onion is sown, timely cover or cover the grass to keep the soil moist and prevent rainstorms. Sunscreen should be used where conditions permit. Conditions do not have local materials, covered with grass. According to the experience of vegetable farmers, the use of Artemisia halodendron covered wheat straw with better permeability and less seedbed contamination.
The process of phosphorus absorption from onions by the onion is very slow, and spraying the onion leaves with phosphorus can promote root development. 10 to 15 days before planting on the leaf surface of onion seedlings sprayed with "Digolide" + 0.2-0.4% potassium dihydrogen phosphate, can increase rooting ability after onion colonization.
