Abstract

The invention provides a method for producing proportioned granulated feed by using crop straws on a large scale. The method comprises the following steps: respectively preparing lignin enzyme bacterial solution and cellulose enzyme bacterial solution; after harvesting crops, immediately spraying the lignin enzyme bacterial solution on the scattered straws, collecting and bundling the straws, transporting the straws to a straw bulk storing yard for stocking and storing, and carrying out specific low temperature-rise or no temperature-rise fermentation by virtue of the process of stocking and storing the straws to complete degradation of lignin in the straws; in slack seasons, spraying the cellulose enzyme bacterial solution on the straws which are unbound and cut short to complete degradation of cellulose in the straws by virtue of the short-term fermentation process on a flat bed in a workshop; and according to the preset or pre-selected recipes for different animal proportioned feed, mixing crop straw feed after double degradation with other feedstuffs to obtain the finished granulated feed product. The method of the invention can realize rapid collection of the crop straws for producing the proportioned granulated feed on a large scale, and effectively improve utilization ratio of agricultural biological yield.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a method for producing compound granular feed using crop straws on a large scale. Background technique [0002] Crop straw is the second largest photosynthetic product in nature after seeds. Since the existing crop straw utilization methods failed to achieve the purpose of rapid harvesting and full utilization of agricultural biomass, a large amount of crop straw was inevitably left idle or burned. Contents of the invention [0003] The purpose of the present invention is to provide a step-by-step spraying treatment of two kinds of bacterial liquids to quickly collect and store crop stalks, and use the treated crop stalks as feed materials that can be effectively used by animals, and then further cooperate with other raw materials to prepare Pellet feed technology. [0004] Method of the present invention comprises the following steps: [0005] 1) Prepara...
