Detailed Explanation of Key Orchid Cultivation Points and Broccoli Planting Management Techniques

Intertillage. Five days after transplanting, carry out one intertillage and weeding, and appropriately earth up around the roots. Depending on weed conditions, the number of intertillage and weeding operations can be increased.

Topdressing. One week after transplanting, apply a seedling-promoting fertilizer, applying urea mixed with water solution + New High-Fat Film in holes 10 cm from the roots. Three weeks later, in combination with intertillage and earthing up, apply high-quality compound fertilizer + plant electronic fertilizer to promote plant growth and development. At five weeks and seven weeks, apply compound fertilizer once more each time, with the amount depending on seedling conditions. Before budding, spray vegetable stem-strengthening agent, which can make plant stems thick and strong, leaves thick and plump, leaf color fresh and tender, and plants lush, with a rich natural taste.

Watering. Within two weeks, watering should be appropriate, alternately dry and wet, to promote root development; after two weeks, keep the field moist, using water to regulate fertilizer; after budding, sufficient water must be ensured, and furrow irrigation can be used when necessary; clear the ditch system to ensure no water accumulates in the ditches during rainy seasons.

Pest and disease control. For cabbage caterpillars, aphids, diamondback moths, armyworms, etc., generally apply pesticide once every 7 days. A 5% fipronil 2500x solution + Tree Guardian General can be sprayed for control. In the middle and late growth stages, attention should be paid to the control of black rot, soft rot, downy mildew, and sclerotinia, using 64% dimethomorph 500x + Tree Guardian General for spray control.
