Sunflower edible (or oil-used) cash crop varieties have relatively large seeds, and as ornamental horticultural varieties, more attention is paid to the ornamental effect of flowering (compared to edible seeds, their size is very small). Development, horticultural varieties Sunflower presents three major development trends: dwarf plants, colorful flowers (multiple series of color varieties such as purple black, orange red, orange yellow, golden, green, etc.), and various flower types (single petal, double petal And petal size). Therefore, this technical article is organized to provide a reference basis for creating a sea of ​​sunflowers in autumn.

Soily site (if there are many weeds in the plot, you must apply the pesticide before deep turning to reduce the workload of weeding in the later management. However, pay attention to the use of the herbicide needs to be more than half a month in advance, so as not to affect Sunflower seeds germinated later), crushed the soil after deep turning, and raked the land.

However, if the north-south direction appears to be directly opposite to the Park Garden Road, the beauty of the landscape is the priority and there is no need to stick to the need for the north-south direction (the direction of the planting ditch is parallel to or oblique to the Yuanyuan Road).
In actual operation, if the soil conditions are better and loose, burrowing is also possible. If the planting volume designed by the Sunflower Flower Sea Project is not large, or the watering in the planting area is inconvenient, or the land consolidation is not timely, seedlings need to be raised in advance. Those who are in the above situation are advised to raise seedlings in a nutrient bowl, the seedlings are about 15 cm high Or transplant when two leaves. Pour water in time after transplanting.
