Problems solved by technology

Among the hay preparation methods of alfalfa, natural drying is the method with the lowest cost and the most widely used method, but it is also the method with the most uncontrollable factors, the easiest loss of nutrients, and the most difficult method
Drying and preparing alfalfa hay under natural conditions can easily cause nutrient loss of the hay, which is mainly reflected in two aspects: First, due to the different drying speeds of stems and leaves, when the moisture content of the leaves has reached the safe water content, the moisture content of the stems is still low. It is very high, and a large amount of leaves will fall off when slightly moved, resulting in a sharp decrease in protein; second, it is easily affected by the weather, especially in the rainy season (July-September) when the second and third crops of alfalfa are harvested in northern Shanxi. Soluble components are lost due to dissolution, which will further prolong the drying time and increase the loss of nutrients

Embodiment 1

[0027] Location: Dongwangzhuang Village, Shuibosi Township, Datong City, Shanxi Province, with an altitude of 1050m, an annual average rainfall of 370-460mm, and an evaporation rate of 1876mm. The strong evaporation period is in spring and autumn, with an annual average temperature of 7.0°C and a frost-free period of 138 days.

[0028] 1. Selection of fine varieties: choose alfalfa king and Algonquin that are suitable for local production as cultivation objects.

[0029] 2. Harvesting: in Northwest Shanxi, alfalfa can be sown twice in one year, and harvested three times in the second year; the first crop is best harvested from the budding stage to the early flowering stage, and the stubble height is 4-6cm ; The last mowing should be carried out in mid-September, and the stubble height is 7-10cm.

[0030] 3. Flattening: Use a flattening mower (New Holland Model 488) to flatten and mow.

[0031] 4. Natural drying: the flattened and cut alfalfa plants are dried on the ground for...

Embodiment 2

[0037] Location: Maozao, Huairen County, Xinzhou City, Shanxi Province, with an altitude of 1070m, an average annual rainfall of 350-470mm, and an evaporation rate of 1800mm. The strong evaporation period is in spring and autumn, the annual average temperature is 7.3°C, and the frost-free period is 135 days.

[0038] 1. Selection of fine varieties: Xinjiang Daye and Algonquin, which are suitable for local production, are selected as the cultivation objects.

[0039] 2. Harvesting: alfalfa sown in spring is mowed twice in one year, and harvested 3 times in the second year; the first crop is best harvested from bud budding to early flowering stage, and the stubble height is 4-6cm; the last crop Cutting should be carried out in mid-September, and the stubble height is 7-10cm.

[0040] 3. Flattening: After mowing, use the crushing method, that is, the layered flattening method of leguminous pasture and crop straw, and roll the alfalfa laid on the ground with a light tractor.

Abstract

The invention discloses a method for manufacturing alfalfa hay. The method includes particular steps of selecting improved varieties; clipping the improved varieties in due time; flattening the improved varieties; naturally airing the improved varieties; bundling the improved varieties; laying the improved varieties; artificially drying the improved varieties and storing the improved varieties. The method for manufacturing the alfalfa hay has the advantages that loss of nutrient substances of alfalfa in airing procedures implemented by a process for naturally drying the alfalfa can be obviously reduced, and the alfalfa hay can keep high nutrition value.

Description

technical field [0001] The invention relates to the field of agricultural science, and more specifically relates to a method for preparing alfalfa hay. Background technique [0002] At present, the status quo of the alfalfa industry in Shanxi is that the production technology is backward, the alfalfa processing machinery and equipment are simple, the product quality is poor, the commodity rate is low, and the competitiveness is poor. The variety, quality and quantity of grass products cannot meet the needs of the domestic and foreign markets, seriously restricting the development of the alfalfa industry. The preparation and processing of alfalfa is the key to obtain high-quality and high-efficiency grass products on the basis of high-yield alfalfa. Hay is one of the important products of alfalfa, and its preparation is an important part of the alfalfa industry, and the preparation technology is the key to ensure high-quality and high-efficiency products. Among the alfalfa ...
