Breeding method

Spring sowing is divided into direct sowing and broadcast sowing, and the more suitable sowing methods are strip sowing or broadcast sowing.

Live broadcast: in the first half of April. Drill in the border, furrow with a row spacing of 50-55cm and a depth of 4-5cm, evenly spread seeds into the furrow, and cover with thin soil after sowing.

Sowing: Arrange the seedbed, water the soles of the feet before sowing, evenly sow seeds on the bed surface, cover the surface with soil, step on it, and propagate by direct seeding. The advantages are fast seedling growth, early harvest and high yield. This method is generally used for sowing.
