1. Sowing When preparing the ground, apply 2500-5000 kg organic fertilizer per acre, the border width is 100-150 cm, the border surface is flat, the trench width is 30 cm, and the depth is 10 cm. Generally, the seedlings are sown from late April to early May, with a sowing amount of 250 grams per mu, and seedlings can emerge 4 to 5 days after sowing.

2. Fixing seedlings 6-8 days after emergence, the height of the seedlings is about 3 cm, and when there are 4 true leaves, it will take time for the seedlings to be fixed, and the thin and weak seedlings are removed, leaving strong seedlings. The fixed seedlings are 7-10 cm apart. Register overseas company

3. Field management After setting seedlings, combined with weeding, apply thin human excrement and urine once, 1000 to 1500 kg per mu. From now on, soil loosening, weeding and fertilization will be carried out once a week while the weather is fine. Fertilizer must be applied after each harvest.

4. Picking: The best time for picking is when the buds of the main and lateral branches are just exposed, pick the tender stems 4 cm above the ground. At this time, the quality is good, the yield is high, the freshness is not old, and the nutrition is rich. If harvesting for the second time, it will be carried out half a month after the first harvesting, and so on for later harvesting.
