The invention belongs to the technical field of aquaculture, and discloses application of chitosan oligosaccharide in preparation of fish feed for promoting fish growth and improving disease resistance of grass carp bodies. Chitosan oligosaccharide is found to be capable of promoting fish growth and improving the disease resistance of grass carp bodies. In the embodiment, chitosan oligosaccharide is added as an immunopotentiator, so that non-specific antioxidant enzyme expression of the liver of the grass carp can be effectively induced, and the autoimmunity of the grass carp is improved. The chitosan oligosaccharide can improve the intestinal flora structure of the grass carp. In the embodiment, the relative abundance of the clostridium of the 3% chitosan oligosaccharide addition group is remarkably higher than that of the control group, and the 3% chitosan oligosaccharide addition group is the most important bacterial genus of the clostridium, so that the chitosan oligosaccharide has a remarkable effect on improving the intestinal flora structure of the grass carp.

This invention discloses a biological agent suitable for squab growth, its preparation method, and its application, belonging to the field of feed technology. It comprises the following components by weight: 8-40 parts of microbial agent, 1-10 parts of additive, 1-10 parts of antioxidant, 0.5-5 parts of peptidoglycan, and 40-60 parts of montmorillonite. The microbial agent includes *Bifidobacterium animalis*, *Lactobacillus acidophilus*, *Lactobacillus paracasei*, and *Lactobacillus reuteri*. The additive includes at least one of yeast β-glucan and astragalus polysaccharide. The biological agent for squab growth of this application uses montmorillonite as a base material. Under the combined action of the microbial agent, additive, antioxidant, and peptidoglycan, it can regulate the intestinal health of breeding pigeons, improve their immunity, and increase immune factors in pigeon milk. This can improve the growth performance of squabs, reduce the culling rate of both breeding and squabs, thereby increasing economic benefits and showing broad application prospects.

The invention discloses a complete method for improving soil and supplementing various elements lacked by plants in a full-ecological mode. The complete method comprises the following steps that 1, organic fertilizer is prepared; 2) preparing an element fertilizer, and mixing the element fertilizer with an organic fertilizer to obtain a mixture; 3) changing the structure of the soil at a certain depth to loosen the soil, and spreading the mixture on the surface of the soil for mixing; and 4) preparing a microbial agent, and spraying the microbial agent to the surface of the soil.
