1、 Planting method
When planting, the hole plate sowing method is usually used. One seed is planted in each hole, and then covered with soil and watered with water. At ordinary times, we should ensure that the soil is moist and provide a suitable temperature environment, about 25 degrees, so that we can germinate and survive in three or four days. If it is sown in spring and autumn, it will bloom in about two months. If it is planted in summer or winter, it can bloom in about 80 days p>
2、 Later maintenance method
1. Light: it likes light, especially during the seedling period, it should be given sufficient sunlight, so that the seedlings can grow more robust, which is beneficial to stem and leaf growth and flower bud differentiation p>
2. Temperature: it is both warm and cold resistant, so don't worry too much about temperature. As long as it is no less than minus 10 degrees, it can grow normally, but the higher the temperature, the faster it will grow p>
3. Watering: usually do not water too much, it is more drought resistant. However, after budding, the amount of water and times should be increased. When the flowers are mature, the amount of water should be controlled appropriately. It is strictly prohibited to accumulate water in the soil, otherwise it will affect the growth p>
4. Fertilization: sunflower likes nitrogen fertilizer, so it should be applied frequently during maintenance. It can be combined with watering at the same time, so that the fertilizer can be better diluted and absorbed by it. Proper fertilization can better promote the growth of stems and stems, but pay attention to timely fertilizer control after budding p>
