Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to an alfalfa plant height measuring device. Background Art

[0002] Alfalfa is a perennial herbaceous plant of the genus Alfalfa in the family Leguminosae. Its stem is erect, tufted or creeping, quadrangular and branched. Its stipules are large, ovate-lanceolate, and its leaflets are obovate-oblong. Its flowers are family-like racemes. Its pedicels are bell-shaped, and its corolla is purple. Its fruits are spiral-shaped and brown when ripe. Its seeds are small and smooth, and are yellow or brown. Its flowering period is from May to July, and its fruiting period is from June to August. It is named as alfalfa because its flowers are purple.

[0003] Alfalfa has the effects of relieving cough and asthma, treating neuralgia caused by difficulty in defecation and urination, etc. These effects are all recorded in the "Famous Doctors' Records". The content of vitamin K in the tender stems and leaves of alfalfa is very high, and it has strong regeneration ability. It is a good livestock feed and a good green manure crop. In terms of ecological value, alfalfa can be used as a soil and water protection and slope protection plant.
