Abstract

The invention provides an alfalfa clone cutting seedling cultivation method, and relates to the technical field of cultivation. The alfalfa clone cutting seedling cultivation method includes (1) seedling bed preparation; (2) cutting scion processing; and (3) harvesting. The method can solve the problem of low survival rate and slow rooting speed of alfalfa cutting, and can improve the disease resistance of the alfalfa and increase the yield of the alfalfa.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a method for growing seedlings by cuttings of alfalfa clones. Background technique [0002] Alfalfa contains a large amount of crude protein, rich carbohydrates, B vitamins, vitamin C, E and iron and other micronutrients. It can not only be used for livestock breeding, but also one of the oldest foods for human beings. People mainly eat the young sprouts of alfalfa when they turn green in early spring. Alfalfa sprouts are high in nutrients, rich in dietary fiber, and have very little sugar. They are very low in calories and are a good high-fiber and low-calorie food. Alfalfa hay is rich in nutrients and is loved by livestock. It contains about 16% protein and 8% minerals, and is rich in vitamins A, E, D and K. Alfalfa stems and branches can quickly regenerate a large number of new stems after harvesting, so hay can be harvested 1 to 13 times in each growing season. [0003...
