III. Key Points of Cultivation Techniques

Destroy the previous crop stubble and level the land, sow with sufficient soil moisture, and for summer sowing the sowing date should not be later than June 25 to ensure uniform emergence, with a density of 13,000 plants per mu. Thin seedlings in good time, and set the seedlings at the three-trifoliolate leaf stage after emergence, remove mixed seedlings, diseased seedlings, and weak seedlings, keep strong seedlings, and the seedlings should be uniform to prevent multiple seedlings in one hole.

Strengthen field management, apply fertilizer reasonably, and water in good time, especially during the flowering and podding stage and the seed-filling stage, when water must not be lacking. At the seed-filling stage, spray 0.2% potassium dihydrogen phosphate on the leaves to increase seed weight.

Harvest and thresh in good time, and store the seeds properly to prevent mildew, which would affect the germination rate.

IV. Suitable Planting Areas

Suitable for summer sowing cultivation in the Beijing area.
