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...
