Embodiment 1

[0021]Example 1: The method for asexual cutting propagation of alfalfa in a semi-arid area includes the following steps:

[0022]S1. Pretreatment of alfalfa material: select the middle part of the dominant single plant material of alfalfa that is drought-tolerant, adaptable, and free from diseases and insect pests during the early vegetative growth period of budding as the cutting seedling;

[0023]S2. Preparation of field seedling substrate: Prepare raw materials in parts by weight: 25 parts of peat soil, 5 parts of bentonite, 10 parts of vermiculite, 15 parts of coconut bran, 1 part of water retaining agent, 2 parts of soil yeast, 10 parts of yellow heart soil, farmyard manure 8 parts, mix these raw materials evenly to prepare the required field seedling substrate. Farmyard manure is made by natural fermentation of cow manure, pig manure and peanut shells. The soil yeast contains actinomycetes, nitrifying bacteria and photosynthetic bacteria. And Aspergillus, the water retaining agent i...

[0028]Embodiment 2: The method for asexual cutting propagation of alfalfa in a semi-arid area includes the following steps:

[0029]S1. Pretreatment of alfalfa material: select the middle part of the dominant single plant material of alfalfa that is drought-tolerant, adaptable, and free from diseases and insect pests during the early vegetative growth period of budding as the cutting seedling;

[0030]S2. Preparation of field seedling substrate: Prepare raw materials in parts by weight: 28 parts of peat soil, 6 parts of bentonite, 13 parts of vermiculite, 18 parts of coconut bran, 2 parts of water retaining agent, 3 parts of soil yeast, 15 parts of yellow heart soil, farmyard manure 10 parts, mix these raw materials evenly to prepare the required field seedling substrate. Farmyard manure is made by natural fermentation of cow manure, pig manure and peanut shells. The soil yeast contains actinomycetes, nitrifying bacteria and photosynthetic bacteria. And Aspergillus, the water retaining ag...

Embodiment 3

[0035]Embodiment 3: The method for asexual cutting propagation of alfalfa in a semi-arid area includes the following steps:

[0036]S1. Pretreatment of alfalfa material: select the middle part of the dominant single plant material of alfalfa that is drought-tolerant, adaptable, and free from diseases and insect pests during the early vegetative growth period of budding as the cutting seedling;

[0037]S2. Preparation of field seedling substrate: prepare raw materials in parts by weight: 30 parts of peat soil, 8 parts of bentonite, 15 parts of vermiculite, 20 parts of coconut bran, 3 parts of water retention agent, 5 parts of soil yeast, 20 parts of yellow heart soil, farmyard manure 12 parts, mix these raw materials evenly to prepare the required field seedling substrate. Farmyard manure is made by natural fermentation of cow manure, pig manure and peanut shells. The soil yeast contains actinomycetes, nitrifying bacteria and photosynthetic bacteria. As well as Aspergillus, the water retai...

Abstract

The invention discloses an asexual cutting propagation method for alfalfa in a semi-arid area, and relates to the technical field of alfalfa cultivation. The asexual cutting propagation method comprises the following steps: S1, an alfalfa material is pretreated, specifically, the middle part of an alfalfa dominant single plant material which is drought-enduring in vegetative growth period, high inadaptability and free from plant diseases and insect pests in the early squaring stage as a cutting seedling. According to the asexual cutting propagation method for the alfalfa in the semi-arid area, when the alfalfa is subjected to cutting propagation, components in a field seedling raising substrate are rich in a large amount of cellulose, carbon sources, organic matter and microelements, goodgrowth environment conditions can be provided for cutting seedlings, the disease resistance can be improved, thus the survival rate is increased, and the labor cost is reduced; and the cutting seedlings are soaked in rooting water, roots are sterilized while rooting is promoted, it is guaranteed that the seedlings are healthy and strong, the survival rate of the cutting seedlings is greatly increased, therefore the roots grow more strongly, economic benefits of alfalfa field planting are guaranteed, and economic development of the semi-arid area is promoted.

Description

Technical field[0001]The invention belongs to the technical field of asexual cutting propagation, in particular to a method for asexual cutting propagation of alfalfa in semi-arid areas.Background technique[0002]Alfalfa is the general name of Medicago sativa, commonly known as golden cauliflower, which is a perennial flowering plant. Among them, the most famous is alfalfa as forage. There are many kinds of alfalfa, most of which are wild herbs. There are mainly three kinds of alfalfa produced in China, which have high nutritional value. It has the effects of clearing the spleen and stomach, improving the small intestines and lower bladder stones. Contains the most abundant vitamin K, which is high in composition and above all vegetables. Others such as vitamin C and B are also quite abundant.[0003]In the prior art, alfalfa uses vegetative cuttings to propagate, which is of great significance for the preservation and propagation of alfalfa, and the breeding of improved varieties. Bre...
