What are the maintenance methods for sunflowers
This article will provide a detailed introduction to the maintenance methods of sunflowers and the green plant flower care skills. Let's dive into the details.
Sunflowers have a strong artistic sense, with attractive shapes and colors. Their fruits can also be eaten as leisure foods, bringing significant benefits to farmers, which has led many people to want to grow sunflowers. So how do you take care of sunflowers? Let's discuss this from the aspects of sowing time, soil requirements, temperature conditions, light and water, field management, and pest and disease control.
1. Sowing Time and Temperature Conditions
Usually, the time to plant sunflowers is from March to April every year, with a suitable temperature range of 18-25℃. Sunflowers are heat-loving plants and can only grow normally when the temperature is above 10℃. Within the range of below 44℃, the higher the temperature, the faster the growth rate.
2. Soil Requirements
When planting sunflowers, the selected soil should have deep soil layers, good drainage, and good aeration.
3. Light and Water
Adequate light not only allows sunflowers to grow better and faster but also improves their seed setting rate and seed quality. Sunflowers do not require much water; keeping the soil moist is sufficient, and more water is needed during the flowering period.
4. Field Management
During the growth stage of sunflowers, there is one very important step: intertilling and weeding. Weeds in the field should be removed promptly to provide a better growing environment for sunflowers. When sunflowers grow to the branching stage, the branches and leaves need to be pruned to provide more space for growth.
5. Disease Control
Sunflowers are very susceptible to sclerotinia disease and downy mildew, which should be prevented with emphasis. Symptoms should be treated promptly, and appropriate fungicides can be sprayed for prevention and control. At the same time, special attention should be paid to protecting the back of the flower disk.
The above provides a comprehensive introduction to the maintenance methods of sunflowers and sunflower care skills, hoping to bring some relevant knowledge of green plants to plant enthusiasts.
