The onion seeds weigh about 3g and have a high soluble sugar content(large plastic terracotta pots). The key technologies for intensive seedling cultivation of green onions are introduced as follows, in order to provide technical support for the standardized and intensive production of green onions. All production links are completed manually, and the production cost per 667m2 is more than 3,000 yuan, regardless of the reduction(3.94inch plastic plant pots). The leaves are dark green, the roots are white, strong but not prosperous, and there are no disease spots.
At present, China's green onion transplanting machinery is mainly imported from Japan(nursery plant pots). The specifications of green onion seedlings should meet the requirements of mechanized colonization. The standard for planting seedlings is: seedling age 45~60d (day), the plant is strong, no lodging, plant height 15cm, pseudo stem length 10cm Left and right, the pseudo stem is about 0.3cm thick, and the functional leaves are 2 to 3 pieces(4.13inch plastic plant pots).
