Cultural method for blooming of potted coreopsis basalis before May

Abstract

The invention relates to a cultural method for flowering plants, in particular to a cultural method for blooming of potted coreopsis basalis before May, and belongs to the technical field of plant culture. According to the cultural method, short and early maturing varieties which are good in ornamental characteristic are selected; after the blooming period is over, deadwoods and old leaves are cut, and fertilizing and disease prevention are performed to promote creeping stems to develop and produce seedlings; the temporary planting manner is adopted to perform sunshading, cooling and culture of seedlings; fertilizer and water are added for growth promotion after pot culture; when the culture management is performed in winter, a greenhouse is adopted for heat preservation and wintering of seedlings, and fertilizer and water are fully applied, so that plants can continuously grow in winter; when the culture management is performed in spring, before squaring, the temperature of the greenhouse is regulated, the moisture content is controlled, before the plants come into the market, ventilation of the greenhouse is performed for seedling hardening, and pesticides are adopted to prevent diseases, so that the adaptability of plants is enhanced, and the plants are moved out of the greenhouse and used for arranging flower beds. The cultural method has the benefits that the ornamental characteristics of the cultured coreopsis basalis are superior to that of the coreopsis basalis cultured by means of a conventional method, the blooming period of the coreopsis basalis is enabled to be earlier for 10-15 days, the coreopsis basalis blooms before 'May day', and becomes the flower of the festival; the potted flower mode is adopted for greening, the environment is beautified, and the income of flower growers is increased.

Description

technical field [0001] The invention relates to a method for cultivating flowers, in particular to a method for cultivating potted coreopsis to flower in advance, and belongs to the technical field of plant cultivation. technical background [0002] Coreopsis basalis (coreopsis basalis) is an annual or perennial perennial herbaceous flower of Compositae.

Flowering in early June. Coreopsis is evergreen in four seasons, with lush branches and leaves, especially in winter when the young leaves germinate and become green in patches, add...

AI Technical Summary

Problems solved by technology

Conventionally cultivated varieties are not cultivated as potted flowers due to their high plant height, thin stems, easy to lodging, small flower diameter, less flowering, and poor ornamental performance of most varieties, which have entered early summer when flowering, short flowering period, and high management costs in summer. Coreopsis is mainly used as a covering material for road greening and slope protection plant roof greening, but the amount of seeds used by flower growers is large, and the economic benefits are relatively low
