Detailed Explanation of Pak Choi Planting Techniques and Management Key Points

Choose fertile soil that is convenient for irrigation and drainage, rich in organic matter, and with good granular structure for planting. It can be planted multiple times a year, with protected cultivation in spring and open-field cultivation in autumn and winter. In sunny weather, water 2-3 times a day. During the growth of pak choi, maintain sufficient nutrients and carry out necessary topdressing. For pest and disease control, spraying the leaf surface with a 1000-fold dilution of imidacloprid can effectively control pests and diseases.

1. Soil Selection

Pak choi has relatively strict requirements for soil selection. It is best to choose higher terrain, convenient irrigation and drainage, fertile soil rich in organic matter with good granular structure, or sandy soil.

2. Seedling Raising and Transplanting

Pak choi can be planted multiple times a year, with protected cultivation in spring and open-field cultivation in autumn and winter. When raising seedlings, the density should be appropriate to improve ventilation and light penetration. After seedling raising and planting, spraying the seedlings with New High-Fat Film can effectively prevent aboveground moisture from evaporating and seedling moisture from transpiring, isolate pests and diseases, shorten the seedling recovery period, quickly adapt to the new environment, and promote healthy plant growth.

3. Fertilizer and Water Management

Because pak choi has a shallow root distribution, high water consumption, is not drought-tolerant, and consumes a lot of nutrients, it requires sufficient fertilizer and water supply throughout the entire growth period to meet the plant's growth needs. In sunny weather, water 2-3 times a day to ensure normal plant growth; pak choi is relatively tolerant of rainwater, but if rainwater accumulates excessively, pay attention to drainage and to preventing the occurrence of soft rot, so as to avoid water accumulation on the bed surface. During the growth of pak choi, maintain sufficient nutrients and carry out necessary topdressing. Fertilization should mainly use decomposed farmyard manure and compound fertilizer, and combine fertilization with New High-Fat Film to increase fertilizer efficiency.

4. Pest and Disease Control

For pest and disease control, use a 1000-fold dilution of imidacloprid and a 1000-fold dilution of emamectin benzoate, and spray the leaf surface to effectively control pests and diseases. Also apply plant cell immune factors to enhance plant stress resistance, which can cause viral DNA to break and undergo apoptosis. The strong immune function induces interferon and active cytokines, inhibits residual virus replication, and promotes positive-energy ecological growth of plants. Based on the disease resistance mechanism of host plants and the principle of utilizing pathogenic toxicity variation, control the reproduction of physiological diseases and infectious diseases in plants.
