Planting and Cultivation Management Techniques
1. Variety selection
Choose varieties with high yield, strong disease resistance, good market quality, and suitability for spring open-field cultivation.
2. Raising seedlings
The seedling age is about 35 days. Standards for strong seedlings: intact cotyledons, 3-5 true leaves, relatively short internodes, a 45-degree angle between the petiole and the main vine, dark green leaf color, thick leaves, sturdy stems, well-developed roots, and no pests or diseases.
3. Fertilizing and making beds, preparing the soil, applying 5 cubic meters of decomposed organic fertilizer, 25-30 kg of superphosphate or 10-15 kg of diammonium phosphate (5-5 kg of superphosphate per cubic meter, 2-3 kg of diammonium phosphate per cubic meter). Before planting, plow and make beds. The bed width is 1.2 m, the height is more than 15 cm, and cover with plastic film.
