Embodiment 1

[0038] A field rapid drying method prepared from alfalfa hay, comprising the following steps:

[0039] (1) Pretreatment

[0040] Before the alfalfa is harvested, the drying aid solution is sprayed on the alfalfa. The spraying amount per ton of alfalfa is 15L. The components of the drying aid solution are as follows, all in parts by weight: 2 parts of potassium carbonate, 0.5 parts of potassium hydroxide, 97.5 parts of water.

[0041] (2) Mowing

[0042] The mowing started on May 16, 2010 (the budding stage), the mowing stubble was 4cm-5cm, and the fresh grass yield was 26.05t / hm 2 .

[0043] (3) Flatten

[0044] The distance between the two pressing rollers of the mowing and flattening machine was set to 10 cm, and the stems of the mowed alfalfa were crushed.

[0045] (4) Tanning

[0046] The alfalfa after fracturing the stalks is directly spread in the field, and the alfalfa is arranged in rows, each row has a thickness of 20cm-30cm, a width of 1.1m-1.2m, and the distan...

Embodiment 2

[0052] A field rapid drying method prepared from alfalfa hay, comprising the following steps:

[0053] (1) Pretreatment

[0054] Before the alfalfa is harvested, the drying aid solution is sprayed onto the alfalfa. The spraying amount per ton of alfalfa is 10 L. The components of the drying aid solution are as follows, all in parts by weight: 2 parts of potassium carbonate, 2 parts of potassium chloride, 96 parts of water;

[0055] (2) Mowing

[0056] Started mowing on June 28, 2010 (sprouting stage), with 4cm to 5cm of stubble remaining, and fresh grass yield of 23.10t / hm 2 .

[0057] (3) Flatten

[0058] The distance between the two pressing rollers of the mowing and flattening machine was set at 15 cm, and the stems of the mowed alfalfa were crushed.

[0059] (4) Tanning

[0060] The alfalfa after the stem fracturing is directly spread in the field, and the alfalfa is placed in rows. The thickness of each row is 20cm-30cm, the width is 1.1m-1.2m, and the distance betwee...

Embodiment 3

[0066] A field rapid drying method prepared from alfalfa hay, comprising the following steps:

[0067] (1) Pretreatment

[0068] Before the alfalfa is harvested, the drying aid solution is sprayed onto the alfalfa. The spraying amount per ton of alfalfa is 10 L. The components of the drying aid solution are as follows, all in parts by weight: 3 parts of potassium carbonate, 1.5 parts of sodium bicarbonate, 95.5 parts of water;

[0069] (2) Mowing

[0070] On August 18, 2010 (early flowering stage), the mowing started, the stubble was 4cm~5cm, and the fresh grass yield was 30.20t / hm 2 .

[0071] (3) Flatten

[0072] The distance between the two pressing rollers of the mowing and flattening machine is set to 20 cm, and the stems of the mowed alfalfa are crushed.

[0073] (4) Tanning

[0074] The alfalfa after the stem fracturing is directly spread in the field, and the alfalfa is placed in rows. The thickness of each row is 20cm-30cm, the width is 1.1m-1.2m, and the distan...

Abstract

The invention relates to a quick field drying method for alfalfa hay blending, comprising the following steps of: pre-processing, beginning to mow from the squaring period to the primary flowering stage of the alfalfa, flattening, spreading to air, tedding, and picking. All steps are finished by the natural conditions, such as insolation, blowing with wind and the like, no special drying equipment is required, and the quick field drying method has low production cost and is simple and easy to operate. The produced alfalfa hay has aromatic scent of green grass, and also has good palatability and higher nutrition ingredients.

Description

technical field [0001] The invention relates to a field rapid drying method prepared from alfalfa hay, which belongs to the technical field of feed processing. Background technique [0002] Alfalfa (Medicago stativa L.) is a perennial leguminous forage, and it is also the forage species with the largest planting area in my country and even in the world. Because of its strong adaptability, high yield, and good quality, it is known as the "King of Forage Grass". With the development of society and economy, especially driven by the adjustment of agricultural structure, the project of returning farmland to grassland, the project of grass field rotation and the rapid development of animal husbandry, the alfalfa planting area and hay production in my country have increased year by year in recent years, and the scale of industrialization has continued to expand. However, the current domestic alfalfa hay products are still in short supply, and the number of imports is increasing yea...
