Embodiment 1

[0037] A method for rapidly establishing alfalfa clones by cutting seedlings, comprising the steps of:

[0038] (1) Preparation of alfalfa vegetative propagation seedbed:

[0039] When using field cuttings, choose a place with flat terrain, sunny ventilation, irrigation equipment, and easy management. Excavate a cutting ridge with a length, width, and height of 60cm×20cm×20cm on the ground or use bricks to build a 60cm×20cm 30cm×20cm cutting slot, the bottom of the cutting slot and the surroundings are covered with plastic, and the plastic at the bottom of the cutting slot is provided with water seepage holes with a distance of 5cm and a diameter of 1-2cm; The soil is flattened and watered thoroughly before cuttings;

[0040] When adopting potted cuttings, carry out in the greenhouse, the height of the seedling pot is 15-20cm, and the diameter is determined as required, and a water seepage hole is arranged at the bottom of the described seedling pot, and according to the size...

Embodiment 2

[0059] A cutting method for rapidly establishing alfalfa clones comprises the following steps:

[0060] 1. Preparation of alfalfa cloning seedbed. Field cutting seedbeds are generally selected in sunny and ventilated places that are easy to manage. Excavate cutting ridges on the ground with a length × width of 60 cm × 20 cm or use bricks to build a cutting slot with a length × height × width of 60 cm × 30 cm × 20 cm. Lay plastic in and around the tank, and there must be water seepage holes with a distance of 5cm and a diameter of 1-2cm at the bottom of the tank to prevent water from accumulating in the soil. Fill the groove with spare soil and flatten it, and water thoroughly before cutting. Potted cuttings can be arranged in a greenhouse. The height of the seedling pot is 15-20cm, the diameter can be determined according to the needs, and there must be water seepage holes at the bottom. According to the size of the seedling pot, multiple plants or one plant can be cut in one...

Abstract

The invention discloses a cuttage breeding method for quickly establishing an alfalfa clone. The cuttage breeding method comprises the following steps: (1) preparing an alfalfa vegetative propagation seedling bed; (2) preparing and sterilizing soil; (3) performing a specific branch cutting operation method; (4) managing cuttage seedlings; (5) transplanting vegetative propagation seedlings; (6) performing filed management after transplanting. According to the cuttage breeding method disclosed by the invention, the problems of being slow in rooting, low in survival rate and the like of alfalfa cuttage breeding can be solved. The method is suitable for quickly and efficiently establishing the cuttage clone, and has the characteristics of being simple to operate, low in cost, quick and efficient, and capable of remarkably shortening the vegetative propagation breeding time and increasing the cuttage breeding survival rate.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a cutting seedling raising method for quickly establishing alfalfa clones. Background technique [0002] Alfalfa (Medicago sativa) is a plant of the genus Medicago in the family Fabaceae, which is an annual or perennial flowering plant. Due to its high grass yield and rich nutrition, alfalfa has the reputation of "the king of forage". Alfalfa is one of the most widely grown pastures in the world. The world's alfalfa planting area is about 30 million hectares, and the annual output of alfalfa hay exceeds 200 million tons. It is very rich in protein and is the best forage for feeding dairy cows. Alfalfa can be used as a complete feed, and its protein, energy, mineral and vitamin content can meet the nutritional needs of various livestock production. In addition, alfalfa has a well-developed root system and biological nitrogen fixation ability, which is an important ecologic...
