2. Fertilization in the whole border: marigold is not strict with soil, 200 kg of soil fertilizer and 2 kg of special fertilizer for chrysanthemum are applied to the seedling bed, and the soil fertilizer is turned into the ground. After the chemical fertilizer is evenly spread on the border surface, it is raked into the ground with a hoe, and then raked fine and leveled.

3. Select seeds: marigold seeds are selected before sowing, and impurities and blighted seeds are removed to ensure that the seeds are full. Then the selected seeds were dried in order to kill bacteria, enhance seed vigor and improve germination rate.

4. Seed soaking and seed dressing: before sowing, soak marigold seeds in 35-40 ℃ warm water for 3-4 hours, then remove them and filter them with clean water, then control dry water to sow seeds. In order to prevent seedling diseases, methyl topiramate or chlorothalonil can be used to treat seeds.
