Detailed Explanation of Key Cultivation Techniques for White Bulao Pole Beans

To cultivate White Bulao pole beans, sowing and seedling raising must be done at the right time; generally, sowing can be done in three seasons: spring, summer, and autumn. Spring sowing is concentrated in mid-March, and planting begins after applying sufficient base fertilizer. Field management mainly consists of intertillage weeding, trellising, and topdressing, with harvesting arranged at the end.

Cultivation Techniques for White Bulao Pole Beans

1. Sowing and seedling raising must be carried out at a suitable time. This variety is suitable for sowing in spring, summer, and autumn. For open-field cultivation, the sowing time is mid-March.

2. Before planting, applying sufficient base fertilizer is a crucial step. Use mainly farmyard manure and high-quality compound fertilizer. Apply the farmyard manure into the soil during plowing, and apply the compound fertilizer into the sowing furrow, taking care to keep the seed and fertilizer separated. The usual planting spacing is 40×85 cm between plants and rows, ensuring about 2000 plants per 667 sq m.

3. Field management mainly consists of intertillage weeding, trellising, and topdressing. When the seedlings are 20 cm tall, apply 25-30 kg of high-phosphorus compound fertilizer and carry out intertillage weeding. When the seedlings are 30 cm tall, set up A-frame trellises and promptly harvest tender pods for market. When the vines reach 150 cm, promptly pinch the tips and prune the branches to improve ventilation and light penetration, then apply 50 kg of high-nitrogen, high-potassium compound fertilizer per 667 sq m to promote rapid plant growth, form new pod-bearing branches, and extend the pod-harvesting period. With proper management, harvesting can continue until after Frost's Descent; if a greenhouse covering is added at this time for insulation, the harvesting period will be extended even further.
