Adequate basal fertilizer: Before sunflower planting, applying sufficient basal fertilizer is one of the key measures to promote growth and flowering. You can choose organic fertilizers, such as well-rotted animal manure, plant residues, etc., or you can use compound fertilizers. When fertilizing, an appropriate amount of fertilization should be carried out according to the fertility of the soil and the amount of fertilizer required by the sunflower, and excessive or insufficient fertilization should be avoided.
Timely topdressing: During the growing period of sunflowers, timely topdressing is also an important measure to promote growth and flowering. In general, after the sunflower has grown two true leaves, it is time to start topdressing. Nitrogen fertilizers such as urea and ammonium sulfate can be selected, and trace elements such as phosphorus and potassium can also be appropriately supplemented. When topdressing, the amount and time of fertilization should be determined according to the fertility of the soil and the growth of sunflowers, and excessive fertilization should be avoided.
Foliar Sprays: Foliar sprays are a quick way to replenish nutrients and are also effective in promoting the growth and flowering of sunflowers. Foliar sprays can choose fertilizers such as potassium dihydrogen phosphate and urea, prepare them according to the concentration on the instructions, and then spray them on the foliar surface. Generally speaking, spraying every 7-10 days, 2-3 times in a row, can effectively promote the growth and flowering of sunflowers.
In general, for sunflowers to bloom quickly, they need to provide sufficient nutrients and a suitable growing environment. When fertilizing, the amount and time of fertilization should be determined according to the fertility of the soil and the growth of sunflowers, and excessive fertilization should be avoided. At the same time, it is also necessary to pay attention to maintaining suitable environmental conditions such as temperature and light to promote the healthy growth and flowering of sunflowers.
