Sunflowers are also known as sun flowers. The functions of sunflowers are mainly divided into two categories: for food and for ornamental purposes. The flower spikes, seed shells, and stems of sunflowers can be used as feed and industrial raw materials, such as rayon, pulp, etc. The flower language of sunflowers is silent love, bright and passionate, symbolizing optimism, bravery, and perseverance.
Techniques for planting and managing sunflowers:
1. Soil
Sunflowers are not picky about soil and can quickly adapt to ordinary soil. However, it is best to give them loose and breathable soil with good drainage as the growing medium.
2. Sunlight
The more sunlight sunflowers get, the better they grow. Make sure to provide them with ample sunlight, even during the intense sunlight of summer, there is no need to shield them.
3. Temperature
Sunflowers are not tolerant of low temperatures. The most suitable temperature for their growth is between 26°C and 29°C. The cultivation temperature should not be lower than 15°C. Promptly insulate them when the ambient temperature is too low.
4. Watering
Water sunflowers when the soil is dry and then let it get slightly moist. Do not water excessively to avoid积水 in the pot, which can cause root rot.
5. Fertilization
Sunflowers are relatively tolerant of poor soil, but they should still be fertilized appropriately to promote growth. You can fertilize them once every半个月, using diluted phosphorus fertilizer, with a recommendation of 0.01% potassium dihydrogen phosphate.
6. Pruning
Pinch the top of the sunflower seedlings when they are 3cm to 4cm tall. Also, pay attention to pruning the overly long, old, and weak branches. Proper pruning can promote the growth of sunflowers.
7. Diseases and Pests
Sunflowers have strong resistance and are less affected by diseases and pests. However, preventive measures should still be taken, and it's best to spray some preventive drugs on them before they germinate.
8. Cutting
Propagation of sunflowers often uses cutting. Simply insert the cut branches into the growing medium in an open-air environment, and sunflowers can survive without special care.
9. Seedling Management
Good seedling management is essential for sunflower planting to ensure full seedlings. During the sunflower planting period, it is not recommended to replant but to replace seedlings. thinning and replacing seedlings should be done when the first true leaves appear, and the final seedlings should be established before the third set of true leaves appear. If there are pests, spray pyrethroids or phoxim.
