A method for planting a
field pattern of a single
oil sunflower variety comprises the following steps that firstly, the row number m and the column number n of planted oil sunflowers are determined, each row and column intersection point is an
oil sunflower planting point and serves as a coordinate point, and the expected pattern is designed by means of the overall visual effect of symbols representing pattern plants; secondly,
soil preparation and fertilization are carried out, the planting points are determined according to the coordinate points, and holes are dug; thirdly, seed selection is carried out, nutritive bowl seedlings serve as the pattern plants for
sowing and
seedling raising, the plants with bowls are transplanted according to the coordinate points of the pattern plants, and meanwhile,
oil sunflower seeds are directly seeded at the coordinate points of background plants; fourthly,
seedling inspection, complementary planting and intertillage are conducted; underground pests are trapped and killed, and
sclerotinia sclerotiorum and
downy mildew are prevented; fifthly, when the
diameter of flower buds of the pattern plants is 1-2 cm, ditching and fertilizing are carried out; after the pattern plants bloom, the golden pattern is formed, and a green background is presented before
budding of the background plants. According to the method, only one single variety is used for planting, operation and management are convenient, the cost is not increased, the visual
impact is strong, and the time period of the optimal pattern viewing period can reach 18 days.
