Introduction to the planting techniques of broccoli

Broccoli seedlings can be planted in the open field when they are 1 month old (usually with three leaves in one heart), with two rows in each row, 40cm and 35cm, and no more than 3000 plants per mu. When planting, after making the pit according to the plant and row spacing on the border surface, carefully remove the nutrition bowl, put the seedling into the pit and cultivate it well, with the appropriate depth of cotyledons just exposed to the ground, and pour enough fixed planting water after planting. It was covered with film to keep moisture and heat preservation, and the seedling was broken after 3 days, and the film hole was sealed with soil.
