Preparation before sowing Establish requirements for selecting seedbeds and preparing the soil. 3. Requirements Select high-yield and disease-resistant excellent varieties that have been identified and promoted in our province to adapt to the ecological conditions of our province. Seed treatment: Dry the seeds under sunny conditions for 2-3 days. Grade and sow the seeds. 3. Sowing Determine the sowing time: mid-to-late April to early May; sowing amount: 500 seeds/m2. 4.

Compact the soil promptly after sowing according to the soil moisture conditions. 5. Field management Fertilization: Advocate soil testing-based fertilization, applying 375kg/ha of fertilizer with a nitrogen, phosphorus, and potassium ratio of 3.1:1:2.2. Leaf fertilization can be carried out based on plant growth. Fertilizers shall comply with the provisions of NY/T 496. Disease prevention and control: - Hemp brown spot disease (also known as hemp spot disease): Control with Bordeaux mixture. - Root mold disease: Control with methylthiophanate, pyraclostrobin, or multisporin. - Frost mold and stalk rot: Control with chlorothalonil. Pest control: - Jumping beetles: Control with cypermethrin, Carbophos, or deltamethrin. - Corn borer and longhorn beetle: Control with deltamethrin.
