Preparation method of sand-stabilizing shrub silage

Abstract

The invention relates to a preparation method of silage for sand-fixing shrubs, which comprises the following steps: stumping and rejuvenating shrubs after the growing season ends, and keeping the stubble height not more than 10cm; in the next year of stumping, the shrub branches are stubbed and harvested in the growth season, and after being naturally aired for 1-2 days, the shrub branches are processed by a rubbing machine until no obvious stalks exist; the silage microbial inoculum is dissolved in warm water (20-30 DEG C) and then placed at normal temperature for 2-3 h, and the addition amount is 0.02 g.kg <-1 >; uniformly spraying the prepared fungicide solution on the shrubs, uniformly stirring, and controlling the water content of the raw materials to be 60-65%; filling into a vacuum bag, compacting, pumping out air, sealing, and fermenting in a dark place for 60 days. The method is suitable for preparing and processing unconventional silage such as silage shrubs, the source of silage raw materials can be widened, the feeding value of unconventional coarse feed is improved, and the method has important significance on resource utilization of regional sand-fixing plants and delicate development of the breeding industry.

Description

technical field [0001] The invention belongs to the field of feed preparation, and in particular relates to a method for preparing sand-fixing shrub silage. Background technique [0002] Facing the serious situation of desertification in my country, the arid and semi-arid sandy areas are actively responding to the national policy of returning farmland to forests and grasslands. While artificially planting sand-fixing shrubs and grasses in large areas, they also select excellent sand-fixing plant species so that they can be used in suitable conditions. The region exerts the optimal resource utilization value. Among them, the excellent sand-fixing shrubs and semi-shrubs not only generally have high economic feeding value, but also proper processing can help make full use of their nutrients and improve their feeding effect. Silage processing technology is widely used in unconventional feed resources such as shrubs and semi-shrubs in my country. As silage raw materials, shrubs h...

AI Technical Summary

Problems solved by technology

Silage processing technology is widely used in unconventional feed resources such as shrubs and semi-shrubs in my country. As silage raw materials, shrubs have problems such as low soluble carbohydrate content and high buffer energy value, which makes it difficult for conventional silage to succeed.

Moreover, my country's research and development models on sand-fixing plant resources for feeding are still relatively lacking.
