Key points of cultivation

Sow seeds. Sowing and raising seedlings from the end of July to the end of August in Jiaodong area. Sowing too early is high temperature and rainy, which is not conducive to the growth of seedlings; too late, small seedlings affect the yield. The amount of seed used per mu is about 0.50 kg. It can be sprayed 150 grams per mu before emergence after sowing to control weeds.

Transplant. Transplanting in the first and middle of November requires the soil to slow down before freezing in order to survive the winter safely. Select the raw stubble land that has not been planted onion and garlic vegetables, apply rotten high-quality organic fertilizer 3000Mel 4000 kg, diammonium phosphate 50 kg, potassium sulfate 50 kg, urea 10 Mel 15 kg, ploughed and leveled to make a bed, 1.10 meters wide, covered with 90 cm wide plastic film, and sprinkled a thin layer of fine soil on the plastic film. The onion seedlings were graded according to size, dipped in 800 times phoxim solution to kill the eggs of onion flies, and planted with bamboo sticks at a depth of not burying the heart leaves. The distance between plants is 10 cm, 8 rows are planted on each border, and watered after planting.

Management in the following year. It was poured back to Qingshui in early March after overwintering. After turning green, the plant bolts, and the total bud is removed when it seems to be unopened, in order to promote the development and growth of the bud. If the bud is removed too early, the bud can not be ejected and affect the growth; if it is too late, the flowering consumes too much nutrition and the yield of green onion is low. Keep the soil dry and wet during the growth period. In mid-late April, 15 kg of urea was sprinkled in combination with watering mu. The growth period of auspicious spring onions is short, and there are generally few diseases and insect pests.

Harvest. The middle and last ten days of May is the suitable harvest time. Remove the flower bolts and old leaves of the mother plant and put them on the market. The harvest time should not be delayed for too long, otherwise the onions will turn into the reproductive growth of the new growth cycle, bolting flowers and reducing the commerciality.
