Asexual reproduction method of wild melilotus officinalis

Abstract

The invention provides an asexual reproduction method of wild melilotus officinalis. Through a composite growth hormone solution of a certain concentration, stems are subjected to rapid dipping treatment, wherein the composite growth hormone solution is a indolebutyric acid and indoleacetic acid mixed solution, a indolebutyric acid and sodium naphthalene-1-acetate mixed solution or a sodium naphthalene-1-acetate and potassium indolebutyric acid mixed solution; then, cutting propagation is conducted. By the adoption of the asexual reproduction method of wild melilotus officinalis, the growth and development of adventitious root primordia of the seed stems are promoted, the growth of root systems is accelerated, the weight of the root system of a single plant is increased, not only can the survival rate of melilotus officinalis be effectively increased, but also the asexual reproduction method is more suitable for large-scale production compared with a method of soaking the stems in the solution for several hours. According to the asexual reproduction method of wild melilotus officinalis, after rapidly dipping the 500 mg / L indolebutyric acid and indoleacetic acid mixed solution, the seed stems of melilotus officinalis are inserted in sandy soil, and the asexual reproduction method of wild melilotus officinalis is perfect.

Description

technical field [0001] The invention relates to a method for asexual reproduction of sweet-scented osmanthus, belonging to the field of wild pasture breeding. Background technique [0002] Melilotus officinalis (L.) Desr., also known as yellow vanilla osmanthus, yellow sweet clover, Moli Laodu, golden flower grass, is a plant of the genus Melilotus officinalis (L.) Desr., an annual or biennial herb with a stem height of up to 3m, the whole plant has aroma, and wild species are distributed in Sichuan and the provinces south of the Yangtze River Basin in my country. Because of its rich protein content, drought resistance and cold resistance, Rhizobium has strong nitrogen fixation ability, it has strong adaptability to neutral or alkaline soil in temperate zone, and plays an important role in improving soil quality. In addition to being used to improve soil quality, sweet-scented osmanthus is also an excellent forage feed and green manure, and has multiple uses such as medicine...

AI Technical Summary

Problems solved by technology

However, there are many deficiencies in collecting seeds for reproduction and breeding: on the one hand, the time for field resource investigation is not necessarily the seed maturity period; on the other hand, it is difficult for the collected seeds to maintain the excellent characteristics of the female parent

Collecting high-quality stems for cutting propagation has little variation and can maintain the excellent characteristics of the mother plant. It is a cheap, fast, and simple propagation method. However, fresh sweet-scented osmanthus stems are directly cut, and the rooting ability of the stems is weak, and the rooting rate is relatively low. Low, the survival rate is not high
