Problems solved by technology

Drying and preparing alfalfa hay under natural conditions is the most widely used and simplest alfalfa drying method in current production, but it is easy to cause nutrient loss of hay, which is mainly reflected in two aspects: first, the drying speed of stems and leaves is different, When the water content of the leaves has reached the safe water content, the water content of the stems is still high, and the leaves will fall off in large quantities when they are slightly moved, resulting in a sharp decrease in protein; second, it is easily affected by the weather, especially the second and third crops in most areas It is easy to be exposed to rain during harvest, which will dissolve and lose the soluble components in alfalfa, and will further prolong the drying time, resulting in moldy alfalfa and increased loss of nutrients

Embodiment 1

[0011] Embodiment 1: the preparation method of high nutritional value alfalfa grass, the moisture is 30~35%, and density is 120-127kg / m 3 alfalfa bales, placed according to the interval between two adjacent alfalfa bales is 18-22cm, two air blowers are placed on both sides of the alfalfa bale, and the two air blowers on both sides of the alfalfa bale are used to 12 alfalfa bales are dried, and 12 alfalfa bales are placed in 4 alfalfa bales in each layer, and 3 layers are placed from bottom to top. The two air blowers are used to dry continuously for 3 hours every day, and the blast time is selected from 09:00 to 16:00, and the finished product is dried continuously for 4 days. The blower is a centrifugal medium pressure fan with a power of 550W and a flow rate of 870m 3 / h. Alfalfa with high nutritional value prepared by the method for preparing alfalfa with high nutritional value.

Embodiment 2

[0012] Embodiment 2: comparative test

[0013] 1 test material

[0014] The test material is "Golden Queen" alfalfa, which is taken from the alfalfa base of Helan Mountain Farm and Ranch in Xixia District, Yinchuan City, Ningxia. The materials taken are all in the early flowering stage, with an average plant height of 108cm. The test alfalfa was mowed on September 8, 2013 using a flat mower (New Holland Model 488), and then on September 9, 2013 at 12:00, 14:00 and 18:00 using a baler (New Holland Holland BC5060) bales alfalfa under different moisture gradients, and controls the density of alfalfa bales at 120kg / m by adjusting mechanical parameters 3 , 150kg / m 3 and 180kg / m 3 . The blower used in the test is a centrifugal medium-pressure fan (CZ-TD550) with a power of 550W and a flow rate of 870m 3 / h.

Abstract

The invention discloses high-nutritive value alfalfa and a preparation method thereof. The preparation method of the high-nutritive value alfalfa comprises the following steps: putting a plurality of alfalfa bundles at intervals, placing two air blowers at two sides of the alfalfa bundles, and drying the alfalfa bundles by virtue of the air blower. The preparation method has the advantages that (1) the alfalfa can be dried within a short time by virtue of the method, so that the problem that the alfalfa is mildewed by virtue of natural drying when being harvested in rainy seasons; (2) stems and leaves of the alfalfa are dried uniformly by virtue of the preparation method disclosed by the invention, so that the problem that the leaves are greatly lost when being harvested is avoided, and the protein loss ratio is greatly reduced; (3) the nutritive value of the alfalfa is maximally utilized, the quality of the alfalfa is ensure; (4) the yield of the alfalfa is increased; (5) the economic value of planting the alfalfa is increased.

Description

Technical field: [0001] The invention relates to alfalfa grass and a preparation method thereof, in particular to alfalfa grass with high nutritional value and a preparation method thereof. Background technique: [0002] my country's animal husbandry is in a critical period of development, and the deep-seated contradictions that affect and restrict the economic development of animal husbandry are constantly emerging. The total number of livestock has increased significantly and the output of pasture has decreased sharply. The quality and quantity of forage have become constraints for animal husbandry the primary issue of industry development. Alfalfa is known as the "King of Grass" because of its rich protein, good palatability, and wide adaptability, and is an important protein feed in animal husbandry. The dried alfalfa hay is a high-quality roughage, a good substitute for concentrated feed and a raw material for compound feed. Drying and preparing alfalfa hay under natur...
