Method of growing seedlings of senecio cineraria in open field

Abstract

The invention discloses a method of growing seedlings of senecio cineraria in an open field, and belongs to the technical field of plant cultivation. By means of optimizing all parameters in the method of growing the seedlings of the senecio cineraria in the open field, the quality of the seedlings is further guaranteed. Carbendazim with the concentration of 0.05% is used for processing seeds of the senecio cineraria so that pathogens and microorganisms carried by the seeds can be killed; a gibberellin solution with the concentration of 2 milligrams per liter is used for processing the seeds so that germination of the seeds can be promoted, and the germination rate and emergence uniformity of the seeds can be increased; during seedling management in a later period, a monopotassium phosphate solution with the concentration of 0.1% and a thoroughly decomposed cake fertilizer solution which is diluted for 100 times can be used for promoting the growth of the seedlings, keeping a full stand of the seedlings, and strengthening the seedlings. By means of the method, time for the emergence of the seedlings of the senecio cineraria can be shortened by 5-10 days, the germination rate is increased, the emergence uniformity is guaranteed, the seedling growing time can also be shortened by 15-20 days, 20-30 days are saved totally from the seeding time to the time when the seedlings are implanted into nutrition bowls, as a result, production efficiency of the senecio cineraria can be improved, and cost can be reduced.

Description

technical field [0001] The invention specifically relates to a method for growing seedlings of silver leaf chrysanthemum in the open field, belonging to the technical field of plant cultivation. Background technique [0002] Silverleaf, Compositae, Centaurea genus, is a perennial herb. The front and back sides of Silverleaf Chrysanthemum are covered with white fluff. When planted in groups, the white leaves are like a white cloud. They are inlaid with other colors of pure color flowers. The effect is excellent. It is an important flower bed and flower border foliage plant. [0003] Silverleaf chrysanthemum can be propagated by seeds or by cuttings, but in actual production, the growth of cutting seedlings is not as good as that of sown seedlings. Rooting of cutting seedlings is slow, the root system is underdeveloped, the diameter of the aboveground part is small, the plant type is low, and the leaves are dry and thin. Seriously affect the viewing effect. Therefore, the met...

[0003] Silverleaf chrysanthemum can be propagated by seeds or cuttings, but in actual production, the growth of cutting seedlings is not as good as that of sowing seedlings. Rooting of cutting seedlings is slow, the root system is underdeveloped, the diameter of the aboveground part is small, the plant type is low, and the leaves are dry and thin. Seriously affect the ornamental effect, therefore, the method of sowing propagation is often used, but there are also shortcomings in sowing propagation: the seed germination speed is slow, the germination is irregular, and the germination rate is low (the germination rate of seedlings in the open field is only 20-28%), and the seedlings The growth of the plants in the early stage is relatively slow. Under normal circumstances, it takes 55-65 days after the buds are neat to be ready for the nutrient bowl.
