III. Key points of cultivation techniques

The previous crop shall be eliminated and the land shall be leveled. The summer sowing period shall not exceed June 25, so as to ensure neat emergence and density of 13,000 plants/mu. Thinning seedlings in due time, fixing seedlings at the three-leaf stage after emergence, removing miscellaneous seedlings, sick seedlings, weak seedlings, keeping strong seedlings, and keeping seedlings uniform to prevent multiple seedlings in one hole.

Strengthen field management, apply fertilizer reasonably, water in time, especially in flower and pod stage and seed filling stage without water shortage. Spraying 0.2% potassium dihydrogen phosphate on leaves at seed filling stage increased seed weight.

Harvest and thresh in time, properly preserve seeds to prevent mildew and affect germination rate.

IV. Suitable planting areas

It is suitable for summer sowing in Beijing.
