Problems solved by technology

However, these areas currently lack oat grass processing technology. The general oat hay processing technology has very strict requirements on water content. If the water content is greater than 15%, the hay will become moldy

Embodiment 1

[0017] The field experiment was carried out in Wangertang Township, Xiahe County, Gansu Province, at an altitude of 2380m. Longyan No.3 oats were drilled in April 2017 with a seeder (the seeding rate was 225kg / hm 2 ), no irrigation during the whole growth period, and manual weeding twice. During the flowering period, use a Shanghai Star MDM1700 disc mower to mow stubbles of 5cm and 15cm respectively, and dry them on the spot until the moisture content is 14%-16% (A), 20%-22% (B), and 25% -26% (C) three levels, and then use the New Holland BC5070 small square baler to make 25kg square bales. Transport the bales back to the straw storage shed, and put them in the shape of "pin", leaving a gap of 15cm between the bales. Samples were taken after storage for 0, 30d, 90d, and 180d, respectively, to check the mildew, and to measure the water content, crude protein, neutral detergent fiber, acid detergent fiber, and ash content.

Embodiment 2

[0023] Field experiments were conducted in Hezuo City, Gannan Prefecture, Gansu Province, at an altitude of 3090m. Baiyan No. 7 oats were drilled with a seeder in late April 2016 (the seeding rate was 225kg / hm 2 ), no irrigation during the whole growth period, and manual weeding once. During the flowering period, use a Shanghai Star MDM1700 disc mower to mow stubble at 5cm and 15cm respectively, and dry it until the water content is 14%-16% (A), 20%-22% (B), 25%-26 %(C) three levels, then use the New Holland BC5070 small square baler to make a 25kg square bundle. Transport the bales back to the straw storage shed, and place them in the shape of "pin", leaving a gap of 20cm between the bales. Samples were taken after storage for 0, 90d, and 180d respectively to check the mildew and determine the water content, crude protein, neutral detergent fiber, acid detergent fiber, and ash content.

Abstract

The invention discloses a high-moisture oat hay modulation method for alpine pasturing regions. The method comprises the following steps 1, variety selection, wherein an oat variety suitable for planting in the alpine pasturing regions is selected; 2, harvesting, wherein harvesting is carried out in the blooming state, and stubbles with the length of 15 cm are reserved; 3, airing, wherein harvested oat grass is aired until moisture is lost to 25-26%; 4, bundling, wherein the oat grass is bundled into square bundles or rectangular bundles with the weight of 25-50 kg by using a small bundling machine; 5, stacking, wherein the grass bundles are stacked in the shape like the Chinese character 'shan' or 'pin' in a straw shed, and the distance between every two adjacent grass bundles is 15 cm; the grass bundles can be directly stacked on cement ground; if the grass bundles are placed on soil, a frame which is 15-20 cm away from the ground is erected by using wood or steel ribs, and then thegrass bundles are stacked on the frame.

Description

technical field [0001] The invention relates to the field of oat grass processing, in particular to a method for preparing oat high-moisture hay in alpine pastoral areas. Background technique [0002] At present, traditional grazing is still the main method of raising livestock in my country's alpine pastoral areas. Due to the short frost-free period, limited grassland biomass, lack of dry and yellow natural pasture grass in winter and spring, and artificially processed pastures, there are few types and insufficient quantity, which seriously affects the development of local animal husbandry. develop. Therefore, it is necessary to vigorously develop artificial grassland. Oats can grow normally in alpine pastoral areas from 2,000 meters to more than 4,000 meters above sea level, providing high-quality forage for livestock. However, these areas currently lack oat grass processing technology, and the general oat hay processing technology has very strict requirements on water con...
