At present, the spring onion is about to enter the sowing period, and now it will introduce its strong seedling cultivation techniques to everyone for reference. First, choose the best species To select varieties with outstanding yield, strong disease resistance, and high quality, such as Zhangqiu scallions, Longji chicken onions and other varieties. Second, the soil fertigation The plot did not plant land plots for onions, garlic, alfalfa, and onions. Priority is given to loam or sandy loam where the terrain is flat, the leewards are sunny, the soil is fertile, and drainage and irrigation are convenient. Mushi fermented organic fertilizer 3000 kg, 10 kg of diammonium, 10 kg of potassium fertilizer, after mixing evenly spread on the surface, and then plowing, do hoe, rake length is generally about 10 meters, width 1 meter. Third, seed processing The amount of mu for the 0.75 to 1 kg. Select new species, sowing the seeds before the sowing, wind Yang treatment, remove impurities, dust, slag and other impurities, select sunny weather drying. The use of carbendazim, chlorothalonil and other disinfectant seed dressing can effectively prevent green onion purple spot, downy mildew, and then the seed dressing after the onion seeds placed in a ventilated and dry place to be broadcast.

Watering began before and after the end of April. After that, water was poured every 10 to 15 days, and 5 kg of urea was applied in combination with watering to promote rapid leaf growth. At the end of May, the watering fertilizer is stopped, and the seedlings are planted for about 20 days, making them more robust and resistant to lodging and disease resistance. In order to prevent the collapse phenomenon after planting in the hot sun, the seedlings will be affected. Disclaimer: Some articles in this website have been transferred from the Internet.
