The sunflower is a multi-year herbivorous plant, rich in variety and colour, with a single petal and a heavy petal of solar flowers, and of high value. The methodology and attention of solar flower cultivation are described below。
One, earth
Sunflowers, while resistant to infertile conditions, are more favourable to growth and flowering than fertile soil. Two corrosive soil + one river sand + one pottery can be blended and a suitable amount of organic fertilizer can be added to the bottom of the basin to ensure soil fertility。
2. Seeding
If the sunflower is planted, the seed is small, the sandy soil is selected, the temperature is maintained between 20 and 25 degrees, and the seeding normally takes place for 10 days, and if it is dense, it can sow。
Iii. Shrimp periods
At first, the seedlings were not tanned, placed in the ventilated areas, grew to the tan, avoided burns and affected the growth of the seedlings, and increased light when two to three branches of the solar seedlings grew。
4. Light
When the sunflowers grow, it is important to maintain sufficient light and to ensure that they grow during a period of eight hours a day, to promote light co-operation and to ensure that they are robust and flowery. Inadequate light can lead to longing and less flowering。
Watering
Solar flowers must be drought-resistant and should not be watered frequently during their growth. The growing season can be watered 3-4 times a week, and the roots of the plant can be poured directly. Water for seeds during flowering periods must be watered from the root so that the water does not cause the flower to fall early。
6. Fertilizing
Solar peanuts are long-term and can be applied to general-type compound fertilizers, approximately once every two weeks. Potassium dihydrophosphate can be sprayed on solar flowers before flowers, and potassium phosphate fertilizer can be replenished, approximately half-monthly, to promote the development of flowers. It would also be possible to make a proper diet and ensure sufficient nutrients。
Note by the secretariat
If the temperature is too high or too low, it enters the hibernation phase and the application of fertilization needs to be stopped, otherwise it can cause obesity. Weak branches of sunflowers, as well as long leaves, are to be trimmed, with a length of 5-10 cm, a new leaf is to be planted and strong。
The above is a description of the way in which solar flowers are grown and the attention given to them. They are very beautiful when they bloom, they are of high value and they are potable。
