Processing method of alfalfa silage

Abstract

The invention provides a processing method of alfalfa silage. The processing method of the alfalfa silage comprises the following steps: (1), carrying out cutting and sun-drying, namely harvesting alfalfa, paspalum notatum flugge and sweet potato vines by performing cutting, sun-drying the alfalfa until the water content is 55-65%, sun-drying the paspalum notatum flugge until the water content is 50-60%, and sun-drying the sweet potato vines until the water content is 55-60%; (2) preparing materials, namely cutting the sun-dried alfalfa into pieces of which the length is 2-3 centimeters, cutting the sun-dried paspalum notatum flugge and sweet potato vines into pieces of which the length is 1-2 centimeters, and then, crushing retinervus luffae fructus and carrying out sieving so as to obtian retinervus luffae fructus powder; (3), chopping the alfalfa, the paspalum notatum flugge and the sweet potato vines, and fully mixing the chopped alfalfa, the chopped paspalum notatum flugge, the chopped sweet potato vines and the retinervus luffae fructus powder according to a weight ratio of (5-8) to (1-2) to (0.5-1) to (0.05-0.1) so as to obtain uniformly mixed materials; and (4), carrying out ensiling, namely containing the mixed materials into plastic bags, pumping vacuum and carrying out sealing, and carrying out storing at 22-28 DEG C for 40-50 days so as to obtain the alfalfa silage. The raw materials of the alfalfa silage are easy to obtain, the processing method is simple, the ensiling time is short, and the success rate is high; moreover, the nutritional characteristics of the raw materials can be maintained for a long time. The prepared silage is rich and comprehensive in nutrition, fine in animal palatability, and good in quality.

Description

technical field [0001] The invention relates to the field of forage processing, in particular to a method for processing alfalfa silage. Background technique [0002] It is recognized as an excellent leguminous forage grass in China and even in the world, and it is the leading grass industry in the world. It plays an extremely important role in animal husbandry production and rural economy. However, there is an imbalance between the production area and the market in China, and the green cut alfalfa cannot be supplied in a balanced manner throughout the year. Especially in many places in my country, the production of hay all causes 20-30% losses due to factors such as rain and fallen leaves. In the main producing areas of alfalfa, the fresh grass of alfalfa produced during the growth period is large and concentrated, and it is difficult to fully utilize it only by local animal husbandry.

Problems solved by technology

However, there is an imbalance between the production area and the market in my country, and the supply of green-cut alfalfa cannot be balanced throughout the year, especially in many parts of our country, the production of hay will cause 20-30% losses due to factors such as rain and fallen leaves.

In the main producing areas of alfalfa, the amount of fresh alfalfa grass produced during the growth period is large and concentrated, and it is difficult to fully utilize it only by local animal husbandry

Cause fresh grass to be surplus in the growing season, and after the full flowering period, due to the increase of crude fiber and the decrease of nutrient content, the quality of the grass is seriously affected

If it is not mowed in time from the bud to the early flowering stage, it will affect the yield of fresh grass

A large amount of harvested alfalfa fresh grass is prone to mold and rot in the rainy season, and there is no rainproof equipment for drying, and no drying equipment for hay preparation, which not only affects the appearance and nutritional quality of alfalfa, but also affects the sustainability of the local grass industry economy. develop
