Problems solved by technology

At present, these areas lack alfalfa processing technology. The general alfalfa processing technology is to pack alfalfa into bales or bales, but this method has strict requirements on water content. Mildew can occur, reducing the nutritional value of alfalfa

Embodiment 1

[0023] The processing technology of alfalfa spiral hay bales in alpine pastoral areas includes the following steps:

[0024] (1) Variety selection: the selected alfalfa variety is Golden Queen;

[0025] (2) Harvesting: the first crop is harvested at the budding stage or early flowering stage in mid-July, and the second crop is harvested at the full flowering stage in late September;

[0026] (3) Spiraling: Firstly spread the fresh alfalfa grass harvested by farmers and herdsmen with conventional household iron forks or wooden forks, so that the stems and leaves are randomly distributed evenly, and spread in the sun for 2 days until the moisture content reaches 50% , screw the alfalfa grass, 2m is 1 unit, then fold it in half and twist it into a twist shape and place it obliquely;

[0027] (4) Drying: Dry the twisted hay bundles in the air again, and store them in the warehouse for natural drying when the water loss reaches 25%.

[0028] (5) Storage: Stack 3-meter-high piles ...

Embodiment 2

[0031] A technology for processing alfalfa spiral hay bundles in alpine pastoral areas, comprising the following steps:

[0032] (1) Variety selection: Algonquin alfalfa;

[0033] (2) Harvesting: the first crop is harvested at the budding stage or early flowering stage in mid-July, and the second crop is harvested at the full flowering stage in late September;

[0034] (3) Spiraling: The harvested alfalfa fresh grass is spread flat on the open concrete floor, and spread with an iron fork or a wooden fork to make the branches and leaves evenly distributed. The machine spirals like a rope, 2m is a unit, then folded in half and twisted into a twist, and placed obliquely;

[0035] (4) Drying: Dry the twisted hay bundles in the air again, and store them in the warehouse for natural drying when the water loss reaches 30%;

[0036] (5) Storage: Stack 3-meter-high piles or erect them with grass racks, and store them for later use.

[0037] The protein content of Algonquin alfalfa h...

Abstract

The invention discloses an alpine-pastoral-area alfalfa spiral-type hay bundle processing technology in a severe cold pasturing area, which comprises the following steps of: (1) selection of variety; (2) harvesting; (3) forming the spiral type; (4) airing; and (5) storage. The alfalfa spiral-type hay bundle processing technology has the advantages of long pasture storage time, low requirement in water content, simplicity and easiness in operation and completeness in protein reservation.

Description

technical field [0001] The invention relates to a pasture processing technology, in particular to a processing technology of an alfalfa spiral hay bundle in an alpine pastoral area. Background technique [0002] At present, the traditional free grazing is still the main way to raise livestock in the alpine pastoral areas of my country. Due to the short frost-free period, the limited biological yield of grassland, the lack of dry and yellow natural pasture grass in winter and spring, and the artificially processed forage species are few and insufficient, resulting in "summer strong" in livestock. Therefore, it is necessary to vigorously develop artificial grassland. Alfalfa can grow normally in pastoral areas below 2800m above sea level, providing high-yield and high-quality forage for livestock. At present, these areas lack alfalfa processing technology. The general alfalfa processing technology is to pack alfalfa into bales or bales, but this method has strict requirements ...
