China rose (Rosa hybrid), rosa genus of Rosaceae family, is perennial evergreen or semi evergreen short shrub, flowers in four seasons, has rich color and variety, can be used as ornamental and medicinal plants, and is widely applied to cut flowers. The China rose is one of four large cut flowers in the world, has high economic value, and is one of flowers with the largest consumption in the cut flower market. The high-quality cut flowers are required to have full flower shapes and attractive shapes, and the length of the flowers is one of indexes for judging the grade and the quality of the cut flowers, and the cut flowers are classified into A, B, C, D, E five grades according to the length of the flowers in the market.
In the production process of cut rose, some varieties have short flower branches and low grades, the commodity value is low (one grade is different by 10cm, the price is different by 0.5 yuan per branch), the quality and commodity value of the cut rose are seriously reduced, and huge economic losses are caused for enterprises and flower farmers. Therefore, it is of great industrial importance to explore a method capable of effectively elongating the length of flowers.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a Chinese rose branch elongation plant growth regulator composition and preparation and application thereof, the Chinese rose branch elongation plant growth regulator composition of the invention takes plant hormone as a main raw material, the preparation method is simple, takes effect quickly, has low cost, is environment-friendly and safe, and effectively solves the industrial problems of short flower branch length, and reduced grade and commodity value.
The technical scheme for solving the technical problems is as follows:
The first object of the present invention is to provide a rose branch elongation plant growth regulator composition, comprising the following raw materials: gibberellin, 1-naphthylacetic acid, an amino acid-containing water-soluble fertilizer and potassium dihydrogen phosphate.
The beneficial effects of the invention are as follows: the plant hormone is used as a main raw material, so that the method is environment-friendly, safe and pollution-free, low in cost, and capable of guaranteeing normal hormone signal transduction and development regulation, further greatly improving the length and quality of cut rose branches and guaranteeing continuous quality improvement and efficiency of industry.
Further, the rose branch elongation plant growth regulator composition comprises the following raw materials in parts by mass:
11-12 parts of gibberellin, 0.8-1.2 parts of 1-naphthylacetic acid, 0.8-1.2 parts of amino acid-containing water-soluble fertilizer and 100-110 parts of monopotassium phosphate.
The beneficial effects of adopting the further scheme are as follows: gibberellin can increase the content of auxin in plants, so that the elongation of cells is directly accelerated, the division of the cells is promoted, and the expansion of stem cells of China rose can be promoted; the 1-naphthylacetic acid is a plant growth regulator with auxin activity, can promote the elongation growth of cells, regulate the growth rate of stems, and the synergistic effect of gibberellin and 1-naphthylacetic acid can promote the elongation of rose branches. The potassium dihydrogen phosphate can improve the hardness of the elongated stems, make the stems thicker, avoid breaking flowers and branches, and finally add the amino acid-containing water-soluble fertilizer to provide nutrients for the growth of flowers, avoid the influence of insufficient nutrients on the quality of China rose caused by the elongation of flowers and ensure the normal growth of China rose.
Preferably, the gibberellin is GA3, and GA3 is one of the gibberellin species having biological activity.
Further, the active ingredients of the amino acid-containing water-soluble fertilizer comprise free amino acids and trace elements.
Preferably, the content of free amino acid in the amino acid-containing water-soluble fertilizer is more than or equal to 100g/L, and the trace elements are Mn, zn, B, fe, mo, wherein Mn is more than or equal to 10g/L, zn is more than or equal to 7g/L, B is more than or equal to 0.5g/L, fe is more than or equal to 2g/L, mo is more than or equal to 0.5g/L.
The second object of the present invention is to provide a method for preparing a rose branch elongation plant growth regulator composition, characterized by comprising the steps of:
Respectively utilizing gibberellin, a mother solution containing the amino acid water-soluble fertilizer and 1-naphthylacetic acid to prepare gibberellin, a mother solution containing the amino acid water-soluble fertilizer and a mother solution containing 1-naphthylacetic acid; and adding the mother liquor of the gibberellin and the mother liquor of the amino acid-containing water-soluble fertilizer into water, uniformly mixing the mother liquor of the 1-naphthylacetic acid and the monopotassium phosphate, finally adding water for quantification, and adjusting the pH of the mixed liquor after full shaking and uniform mixing to obtain the rose branch elongation plant growth regulator composition.
The beneficial effects of the invention are as follows: on the premise of ensuring the quality (important characters such as flower color, flower shape and the like) of flowers, the plant growth regulator composition developed by the invention has the advantages of simple and convenient preparation process, quick response, low cost, environmental protection and safety, obvious effect and capability of effectively promoting the elongation of flowers and improving the quality of cut flowers.
Further, the volume ratio of the mother liquor of gibberellin, the mother liquor of the amino acid-containing water-soluble fertilizer and the mother liquor of the 1-naphthylacetic acid to water is (11-12): (0.8-1.2): (0.8-1.2): (85-88). The plant growth regulator composition for the rose branches, which can be used for adding water into gibberellin mother liquor, amino acid-containing water-soluble fertilizer mother liquor, 1-naphthylacetic acid mother liquor and monopotassium phosphate to fix the volume, contains 11-12 parts by mass of gibberellin, 0.8-1.2 parts by mass of amino acid-containing water-soluble fertilizer, 100-110 parts by mass of monopotassium phosphate and 0.8-1.2 parts by mass of 1-naphthylacetic acid.
