Alfalfa quality improving drying method

Abstract

The present invention relates to an alfalfa quality improving drying method which comprises the following steps: 1) harvesting and flattening; 2) a first turn-over; 3) a second turn-over; 4) bundling; and 5) natural air-drying or desiccant drying. The alfalfa production drying methods are different in rain or shine weather, high or low latitudes, and specific time of turn-over and turning sun-drying. According to wet and dry, and different rainfall amount in different regions, and different drying methods, the solar thermal power and wind energy in the nature are maximumly taken advantages of and thus the drying quality is ensured at the same time. By harvesting and flattening, turn-over and ventilation, bundling, and sun-drying, green drying is achieved. The produced alfalfa bundle is emerald green, has a leaf containing rate of 62-65%, is high in cellulose, protein, and carotene content, and is good in palatability and commodity.

Description

technical field

[0001] The invention belongs to the field of pasture processing, and in particular relates to a drying method for improving the quality of alfalfa. Background technique

[0002] The country's more than 2 billion (only) grass-fed livestock and poultry lack more than 200 million tons of high-quality forage every year, which is an important guarantee for adjusting the agricultural structure and developing grain-saving animal husbandry. Forage industry is the foundation and guarantee for maintaining food security, ecological security, and homeland security in my country, and is a prerequisite for promoting the sustainable development of modern grassland animal husbandry.

[0003] Alfalfa is a general term for plants of the genus Medicago, commonly known as "clover" (clover can also be called other clover plants). It is a perennial flowering plant. The most famous of these is alfalfa (Medicagosativa) used as pasture. Alfalfa is livestock feed. Annual or perenn...

[0026] Such as figure 1 Shown, a kind of drying method that improves alfalfa quality, comprises the following steps:

[0027] 1) Harvesting and flattening;

[0028] When less than 1 / 10 of the alfalfa blooms and the moisture content of the alfalfa is 78-80%, the alfalfa plants that are more than 5cm above the ground are flattened by a harvester or manually, and the field is directly laid;

[0029] 2) Turn over once;

[0030] After drying in the sun for 9 hours on a sunny day, turn over the alfalfa in the flat field once;

[0031] 3) Second flip;

[0032] After drying in the sun for 32 hours on a sunny day, turn over the alfalfa in the flat field for the second time;

[0033] 4) bundling;

[0034] When the moisture content of the alfalfa in the flat field is 65-70% after drying for 48 hours, the bales are bundled at 7:00-11:00 on cloudy days, and the diameter of the bales is not more than 30 cm;
