Embodiment Construction

[0014] A kind of method of improving high-moisture alfalfa silage quality by adding jujube powder for forage in the embodiment of the present invention is as follows:

[0015] 1. Harvest the alfalfa and chop it to a length of 2-3cm, and weigh it.

[0016] 2. Put the chopped fresh alfalfa into the silo, and flatten it. The flattened thickness is about 8-12cm, generally about 10cm; according to the weight of the alfalfa, weigh 3%-12% for feeding Jujube powder, and evenly sprayed on the flattened alfalfa, the optimal amount of jujube powder for feeding is 6%.

[0017] 3. Use special cellar pressing machinery or suitable alternative machinery for compaction, and the compaction density should be controlled at 500kg / m 3 -650kg / m 3 If the compaction density is too low, there will be too much residual air in the silo, which will affect the quality of fermentation and alfalfa silage; if the compaction density is too high, the juice in the alfalfa will seep out in large quantities, re...

Abstract

The invention relates to a method for improving the quality of high-moisture alfalfa silage. The method steps are as follows: 1. Harvest the alfalfa and chop it to a length of 2-3 cm, and weigh it. 2. Pour the chopped fresh alfalfa into the silo, and flatten it. The thickness of the flattened alfalfa is about 8-12cm; according to the weight of the alfalfa when weighing, weigh 3%-12% of the alfalfa's weight. Powder, and evenly sprayed on the flattened alfalfa. 3. Use special pit-pressing machinery or suitable alternative machinery for compaction, and the compaction density should be controlled at 500kg / m3-650kg / m3; and so on, carry out layer-by-layer compaction and then fill until the silage pit is filled. 4. Cover and seal the top of the filled silo with a plastic cloth and suppress it. The invention can economically and effectively complete high-moisture alfalfa silage, improve the quality of alfalfa silage at the same time, expand the effective utilization way of forage jujube powder, organically combine the production of alfalfa and the waste utilization of jujube industry, and achieve a win-win effect .

Description

technical field [0001] The invention relates to a method for making high-moisture alfalfa silage, in particular to a method for improving the quality of high-moisture alfalfa silage by adding feed jujube powder. Background technique [0002] In the production of alfalfa silage, the sugar content of raw materials is low and it is difficult to silage, especially the high-moisture alfalfa (moisture content 70%-80%) silage. At present, additives are often used in the world to solve this problem. However, most of the existing additives are imported or packaged products, which are expensive and increase the production cost of silage; at the same time, most of the additives are more suitable for low-moisture alfalfa silage, but not ideal for high-moisture alfalfa silage. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the quality of high-moisture alfalfa silage by adding jujube powder for forage. The effective utilizat...
