1. Land selection and preparation

Golden sunflower has strong growth ability, developed root ability, and can adapt to all kinds of soil, but it wants to plant high-yield and high-quality sunflower. It is still necessary to choose plots with deep soil layer, sufficient fertility and normal drainage and irrigation. Sunflower should not be planted in potholes, prone to stagnant water, otherwise it is easy to rot, affecting the growth of sunflower. After selecting the land, it is necessary to do a good job in soil preparation, ploughing deeply, applying rotten base fertilizer, and then preparing the border for sowing, and pay attention to the specifications of the border, which is about 20 to 20 centimeters wide and 20 centimeters high, which is convenient for planting management.

2. Sowing seeds at the right time

The growth period of sunflower is about 4-5 months, and the sowing time should be controlled according to the weather and variety factors of the planting area. For example, the suitable sowing time in southeastern China is about April, and the seed germination power of sunflower is relatively strong, but in order to ensure the germination rate, we still have to carry out germination work before planting. First of all, you should choose full, no obvious wounds and no diseases and insect pests, and then soak the seeds in warm water of about 30 degrees for about 24 hours. Remove and dry it and wrap it in a wet cloth and put it at a temperature of about 26-28 degrees Celsius for budding. When more than 50% of the seeds are white, they can be sown.

After underwater infiltration, put a seed in each seedling hole, cover the fine soil after sowing, and spray water properly to improve the moisturizing ability of the nutritious soil. After watering, cover with a layer of plastic film, strengthen management, set up a small arch shed properly to promote seed germination. The plastic film can be opened when about 75% of the seeds germinate, and can be planted when the seedlings grow to about 3 leaves and 1 heart.
