Embodiment Construction

[0010] 1. Selection of seeds and substrate

[0011] In this experiment, the medium-sized red double-petal aster harvested in the previous year (the plant height is about 40cm, and the germination rate is above 70%) is used as the substrate. The Swiss "Pinshi" flower substrate is used.

[0012] 2. Sowing

[0013] (1) On April 20th (Changchun), choose a flat and easy-to-manage protected area as a seedbed. The area is 2 square meters, and the substrate is evenly spread with a thickness of 3 cm. After watering, 30g of spare seeds are evenly sprinkled. Then cover the substrate evenly, with a thickness of 0.3 cm, and then pour a small amount of water. After the emergence of the seedlings, they are under normal management. Due to the different climates in the north and the south, the sowing time is different. For example, the suitable sowing period in Jiangsu is mid-to-early July, and the suitable sowing period in Changchun is mid-April); in this experiment, seedlings were raised ...

Abstract

The invention discloses a method for improving a seed yield of double China aster and belongs to the technical field of flower seed collecting cultivation. The method comprises the steps of seeding and growing seedlings according to local normal sowing time of different areas, and performing hole tray seeding or broadcast sowing; planting the seedlings in a field when each seedling has four leaves and one core in about one month after seeding; and completely shearing tops and top ends of all primary branches when the buds just appear at the top ends of the China aster. Through the treatment, a larger number of flowers can grow out at the positions of axils of the primary branches, the size of each scape is one third or a half of a normal scape, most of the flowers are semidouble, the length of each petal is about one third of the length of a normal petal, and fructification conditions are good. Through the method, a larger number of small semidouble flowers can grow out at the positions of the axils of the primary branches, stamens are exposed outside, pollination by insects is not influenced, the fructification conditions are good, and the seed yield is improved by over 6 times.

Description

technical field [0001] The invention relates to a method for collecting and cultivating seeds of double-petaled aster for improving seed yield, and belongs to the technical field of flower seed collecting and cultivation. Background technique [0002] Aster is an annual herbaceous shallow-rooted plant. The whole plant is sparsely short-haired. The stem is erect, with many branches in the upper part, 40-100cm high. The leaves are alternate, the leaves are ovate to oblong, thick and bluntly serrated, the lower leaves are stalked, and the upper leaves are sessile. The head inflorescence is solitary on the top of the branch, and the flower diameter of the cultivar is 3~15cm; the cultivar has rich flower colors, such as red, blue, purple, white, yellow and other shades; according to the petals, it can be divided into double petals, semi-double petals and single petals. It has abundant flowering and a long flowering period. It is an ornamental plant that is highly valued by the...
