Abstract
The invention solves the technical system that the leaves of commercial seedlings of potted foliage plants, namely the colorama and the ribbed grass (Aglanonema spp), are changed from green to ornamental colors. The potted seedlings of the spartina macrorrhiza are treated by nutrient components, plant growth stimulin and the like, so that the color of the leaf surface of the potted seedlings of the spartina macrorrhiza is gradually changed from green leaf surfaces in the vegetative growth period to colorful leaves with higher ornamental value and economic value. The use of the technology can divide the industrial production of the color-leaf coarse costal herbs into two stages from the technical aspect: the first stage is mainly to promote the vegetative growth to build a beautiful potted plant shape; in the second stage, the leaf surface is promoted to be changed from green to bright color leaves. The technology can solve the contradiction of promoting the vegetative growth and the transformation of the color leaves in the production of the coarse costwort, and the technology system has low production cost, environmental protection, no environmental pollution and shorter period, and completely realizes the aims of low cost, high quality, uniformity, ornamental value and high market price.
Description
Technical Field
The invention belongs to the technical field of plant nutrition and cultivation, and particularly relates to a technology for promoting the color transformation of leaves of commercial seedlings of zoysia cantoniensis hance.
Background
Roughhaired Ribes burejense (Aglaonema Schott) belongs to Araceae (Araceae) plant. The color-leaf burley grass has rich ornamental characters, bright and elegant leaf color and higher ornamental value. The burley grass is strong light resistant, shade moisture resistant, high temperature resistant and sultry resistant, and is a preferred ornamental plant variety for excellent indoor potted plants, water culture, renting and arranging and the like. The research on the domestic market finds that the rabdosia bicolor is a very popular ornamental species with wide potential and is in a state of short supply. Belongs to one of high-value ornamental plants in facility cultivation varieties. The ornamental point of the ribbed colorama is that the accumulation of anthocyanin in the leaves of the ornamental point shows a different streak from that of green leaves under the influence of pH in the tissues of the leaf organs. The expression of bright color of colored leaves mainly derives from the influence of three aspects of anthocyanin accumulation, plant cell sugar accumulation and cell PH. The higher the anthocyanin accumulation is, the higher the soluble sugar accumulation is, the easier the anthocyanin accumulation is to promote intermolecular or intramolecular co-coloration, the higher the stability is, and when the PH is low, the darker and red color leaf patches are obviously represented, and the ornamental value is higher.
The main current facility cultivation and planting technology is that N, P, K compound fertilizers (namely N-P2O5-K2O:20-20-20 balanced fertilizers) with the same mass concentration are applied for vegetative growth; before the sale period, the high phosphorus potassium fertilizer is applied to promote the concentration of soluble sugar in plant tissues to promote the color conversion of the leaf surfaces. However, in the actual production, because of environmental climate factors (such as illumination, temperature and temperature difference in production areas), physiological age factors of plant leaf organs, synthesis and stability of anthocyanin per se, accumulation of soluble sugar and the like, bright colors are difficult to be shown in most seasons every year, and the ornamental value and the economic value of the anthocyanin are greatly weakened.
The climatic conditions of subtropical regions in the cultivation and production area of the ribbed colorama: insufficient illumination in facility cultivation in a long season is particularly serious, and particularly, the plant tissue anthocyanin is reduced in synthesis and poor in stability due to various characteristics such as short wave light deficiency, temperature stuffiness, small day and night temperature difference and the like; the high phosphorus supply in the fertilization causes strong plant respiration in high-temperature seasons and high consumption and difficult accumulation of soluble sugar. In combination, the commercial seedlings are difficult to change color or have poor color spot quality under the planting technology.
In addition, the method is to apply the high-concentration fertilizer solution for a long time, create a certain osmotic stress rhizosphere environment, accelerate the maturation and even the aging of leaf organs and achieve the effect of leaf color transformation. However, the long-term stress in the vegetative growth period of the seedling causes the poor plant shape of the potted seedling, and the poor blade glossiness of the seedling is difficult to achieve the high-quality commercial seedling quality.
The prior art is difficult to solve the contradiction between the ornamental color transition of the color-leaf thick costal grass and the climate characteristics of the market demand time period. Therefore, according to market demands, the ornamental plant, namely the burley grass, can be timely converted into bright colored leaves meeting the ornamental demands in adverse weather periods according to the market demands, the finished product rate of commodities in planting production can be increased, the turnover rate of agricultural cultivation facilities is improved, and greater economic value and higher ornamental value are created.

Example (b): in order that the invention may be more readily understood, specific embodiments thereof will be described further below.
Example 1, corniculate (Aglanonema spp.) 'promoting colourful leaf conversion of the ruyi' variety:
in this example, a color leaf variety of burley grass (Aglanonema spp.) was selected for cultivation. The variety has the advantages of fast growth, beautiful plant shape extension, bright white or pink half-point distribution of the green background of the leaves during the vegetative growth period of the plantlet, and excellent ornamental property. However, when the temperature of the environment is low (below 15 ℃), the lower leaf of the variety is easy to have verticillium wilt, and the symptoms are prolonged to the whole plant when the stress lasts. In addition, the color development quality of the color leaves is poor, the red patches on the leaf surfaces are small, and the color is not deep red enough in the setting production of the color leaves under the Guangzhou climate condition.
Selecting a tissue culture seedling of the 'Ruyi' of the Roughtonia crassipes (Aglanonema spp.), planting in the last 10 th of the next half year, controlling water, and applying fertilizer solution I in the low-temperature season after new roots grow out. And the No. II fertilizer is applied at the 3 rd month of the next year. In 7 th month, the color is changed by using fertilizers III and IV. The results show that compared with the control treatment, the effect of the invention for treating the seedlings, no matter the resistance in winter, the growth speed in spring and summer, the plant formation and the color conversion treatment is obviously superior to the effect of the control conventional technology for culturing the seedlings.
Example 2, color promoting leaf conversion of Roughtonia grossedentata (Aglanonema spp.) 'Jilishong' cultivar:
the variety has large color spots on the growing leaf surface, better low temperature resistance compared with the 'Ruyi' variety, and round and smooth leaves. The seedlings exhibit several advantages during vegetative growth. However, this variety grows slower than the ` Ruyi ` variety. In addition, when the color is developed by the medium-color leaves in the setting production under the Guangzhou climate condition, although the color spots are large, the color is not deep enough, the color is often pink, and the deep red color is difficult to develop.
Selecting a tissue culture seedling of the Roughtonia crassipes (Aglanonema spp.) of Jilihong in 11 months, planting, controlling water, and applying No. I fertilizer liquid in a low-temperature season after new roots grow out. And the No. II fertilizer is applied at the 3 rd month of the next year. And 8, beginning to use fertilizers III and IV to process color change in the middle ten days of the month. The result shows that compared with the control treatment, the method for treating the seedlings by the technology has the advantages that the plant shape of the seedlings is extended, the whole leaves become red, the color is darker red, and the effect is obviously superior to that of the conventional technology for culturing the seedlings by the control.
