Problems solved by technology

However, due to the long-term stress in the vegetative growth period, the potted seedlings have poor plant shape and poor leaf gloss, and it is difficult to achieve high-quality commercial seedlings.
[0006] The current technology is difficult to solve the contradiction between the ornamental color change of Coleus coleus and the climate characteristics of the market demand period

Embodiment 1

[0080] Embodiment 1, the color leaf transformation of Aglanonema spp. 'Ruyi' variety:

[0081] In the present embodiment, a color-leaved variety 'Ruyi' of Aglanonema spp. is selected for cultivation. This variety grows fast, and the plant shape stretches beautifully. During the vegetative growth of seedlings, the green background of the leaves is white or pink, and the ornamental properties are excellent. However, this variety is prone to chlorosis of lower leaves when the ambient temperature is low (below 15°C), and the symptoms will extend to the whole plant if the stress continues. In addition, the color rendering quality of its colorful leaves under Guangzhou climate conditions is poor, the red spots on the leaves are small, and the color is not deep red enough.

[0082] Select the tissue culture seedlings of Aglanonema spp. 'Ruyi' and plant them in the second half of the year in early October. Control the water and apply No. 1 fertilizer solution during the low temperatu...

Embodiment 2

[0083] Embodiment 2, the rapid color leaf transformation of Aglanonema spp. 'Jilihong' variety:

[0084] This variety has larger colored patches on its growing leaves, and has better low temperature resistance than the 'Ruyi' variety, with rounded leaves. During the vegetative growth of seedlings, the above advantages are shown. However, the growth of this variety is slower than that of the 'Ruyi' variety. In addition, although the color spots of the color leaves in the facility production under the climate conditions in Guangzhou are larger, the color is not deep enough, and it often appears pink, but it is difficult to appear deep red.

[0085] In November, the tissue-cultured seedlings of Aglanonema spp. 'Gilihong' were selected and planted, and the water was controlled until the new roots grew, and the No. 1 fertilizer solution was applied during the low temperature season. In March of the following year, fertilizer No. Ⅱ was applied. In mid-August, the fertilizers No. ...

Abstract

The invention solves the technical system for changing the leaves of commercial seedlings of the potted foliage plant Aglanonema spp. from green to ornamental color. The potted seedlings of Sclerostifolia are treated by nutrients, plant growth stimulants, etc., so that the color of the leaves changes from green leaves in the vegetative growth period to colored leaves with higher ornamental value and economic value. The use of this technology can divide the industrial production of Coleus coleus into two stages from the technical aspect: the first stage mainly promotes vegetative growth and builds a beautiful potted plant shape; the second stage promotes the leaf surface to change from green to green Brightly colored leaves. This technology can solve the contradiction of promoting vegetative growth and color leaf transformation in the production of rough rib grass, and the production cost of this technical system is low, environmental protection does not pollute the environment, and the cycle is short, fully realizing low cost, high quality, uniformity, and ornamental The purpose effect of high value and market price.

Description

technical field [0001] The invention belongs to the technical field of plant nutrition and cultivation, and in particular relates to a technology for promoting the color change of leaves of commercial seedlings of Coleus coleus. Background technique [0002] Aglaonema Schott belongs to the family Araceae. Coleus coleus has rich ornamental characters, bright and generous leaf color, and has high ornamental value. Moreover, it is resistant to strong light, shade and humidity, and high temperature and heat. It is the first choice for indoor potted plants, hydroponics, and other ornamental plants. The current domestic market research has found that Coleus coleus is a very popular ornamental species with great potential, and the supply is in short supply. It belongs to one of the high-value ornamental plants in the protected cultivation varieties. The ornamental point of Coleus coleus is that the anthocyanins in its leaves accumulate under the influence of pH in leaf organs an...
