Cutting and seedling raising method for Senecio cineraria

Abstract

The invention belongs to the technical field of planting, and discloses a cutting and seedling raising method for Senecio cineraria. The method comprises the steps of (1) planting a Senecio cinerariamaternal plant in a cultivation matrix, spraying a nutrient solution, and timely watering; (2) placing a cutting matrix in a 72-hole tray; (3) picking cutting slips after the Senecio cineraria maternal plant grows in the cultivation matrix for 10-20 days, cutting the cutting slips into cutting branches with the length being 3-5cm, soaking the cutting branches in a rooting solution for 1-3min, thencutting the cutting branches into the cutting matrix, profoundly watering immediately, spraying the cutting slips with carbendazim, placing the cutting slips in a greenhouse, setting a sunshade abovethe seedbed for shading, spraying water timely, spraying a foliar fertilizer 10 days after cutting, and then spraying the foliar fertilizer every 10-15 days after watering until obtaining rooted Senecio cineraria seedlings. The cutting and seedling raising method is simple and high in propagation speed, the survival rate of Senecio cineraria cutting propagation reaches up to 98% or above, and thecutting and seedling raising method can be applied to large-scale production.

Description

technical field [0001] The invention relates to the technical field of silver leaf chrysanthemum planting, in particular to a method for growing seedlings of silver leaf chrysanthemum cuttings. Background technique [0002] Silverleaf, Compositae, Centaurea, also known as snowflakes, is a perennial herb. The silver leaf chrysanthemum leaves are spoon-shaped or pinnately split, the front and back are covered with silver-white pilose, the leaves are thin, and the leaves are missing, like snowflake patterns, with long white hairs. Inflorescence head solitary branch top, purple-red flowers. The whole plant has white hairs. The plant is multi-branched, the leaves are pinnately divided once or twice, and the front and back are covered with silvery white pilose, head-shaped inflorescence The top of the solitary branch, the flowers are small, and the front and back of the yellow silverleaf are covered with white fluff. When planted in groups, the white leaves are like a white c...

Problems solved by technology

Silverleaf is a fertilizer-loving plant. During the planting process, it is often due to insufficient nutrition, the silvery white brightness of the leaves is not high, and the vegetative growth is slow, which affects the ornamental value of Silverleaf.

[0004] Silverleaf chrysanthemum can be propagated by seeds or by cuttings. However, the traditional cutting substrate has a single function, poor water and fertilizer retention performance, and it is difficult to control later management. The roots are rotten, therefore, the survival rate of traditional cuttings is not only low, but also the cost of raising seedlings is high
