The invention relates to a plant wound protective agent containing chitosan oligosaccharide which contains chitosan oligosaccharide and one or more of a nutritional agent, an adjusting agent and a sterilizing agent, wherein the weight percentage of the chitosan oligosaccharide accounting for the protective agent is 0.0015-0.03 percent. The plant wound protective agent can be used for spraying or smearing. The prepared solid preparation for smearing also contains a film-forming agent. On one to five days before pruning, girdling or grafting, the wound is sprayed by using the protective agent; and on one to five days after the pruning, girdling or grafting, the wound is smeared by the protective agent, so that disease attacks of the wound can be reduced and the healing of the wound can be promoted. The plant wound protective agent is used for apple trees, pear trees, peach trees, jujube trees, grape trees, mango trees, longan trees, lychee trees, citrus trees, watermelon, maidenhair trees, honeysuckle, Arabian jasmine flower and Chinese rose.

The invention discloses a ploughing method for grassland powder ridges to gather water and enrich grass. A high-horsepower rotary tiller is used to carry out moderately deep plowing. The specific requirements are as follows: a. A strip-shaped powder ridge is carried out with a tillage width of 80-200 cm, and the depth is 30-40 cm; b. In the edge area of ​​the forage planting area, plough the powder ridge once every 15-20m, so that the soil of the powder ridge is 10-12cm above the ground, and the bottom of the loosening tank is "U" shaped, which is convenient for water storage and water protection; Measures such as drainage channels, mulching, grass planting and management play an important role in maintaining the balance of water and soil in grassland areas, increasing forage production, and ultimately improving the development of animal husbandry.

The invention discloses a stabilization ponds-ecological corridors-constructed wetland based tail water treatment system, and belongs to the technical field of sewage treatment. The system comprises stabilization ponds (an aerated pond, a facultative pond and an aerobic pond), ecological corridors (1#, 2# and 3#) and a surface flow wetland; and tail water for treatment sequentially goes through the aerated pond, the 1# ecological corridor, the facultative pond, the 2# ecological corridor, the surface flow wetland, the 3# ecological corridor and the aerobic pond, and is discharged. The system uses biological treatment as a main means, is based on the theoretic research on the removal of pollutants through the aerated pond, a trench wetland and the constructed wetland, follows the conversion rule of main pollutants in tail water, optimally combines different types of the stabilization ponds with the constructed wetland, and utilizes the ecological corridors modeled on the trench wetland as a water conveying trench to form a tandem type aerobic-anaerobic reactor in order to promote the effective removal of the pollutants in the tail water.

The invention discloses an ectopic fermentation bed livestock breeding excrement treatment system and an application thereof. The ectopic fermentation bed livestock breeding excrement treatment system comprises at least one breeding house, a dirt collecting tank, a first cutting pump and a fermenting house, wherein the fermenting house comprises a plurality of ectopic fermentation beds, a spray tank and a spray device; the bottom of the breeding house communicates with the dirt collecting tank; one end of the first cutting pump communicates with the dirt collecting tank, and the other end of the first cutting pump is connected to the spray tank; the spray tank is positioned among the four ectopic fermentation beds; the spray device comprises a second cutting pump and a plurality of spray pipes; one end of the second cutting pump communicates with the spray tank, and the other end of the second cutting pump separately communicates with the plurality of the spray pipes; and each spray pipe is correspondingly arranged above one ectopic fermentation bed transversely, and a plurality of water spray holes are formed in the side walls of the spray pipes. According to the ectopic fermentation bed livestock breeding excrement treatment system, the excrement generated by pig breeding is mixed with padding for fermenting, so that the odor and toxin of the pig excrement are eliminated, the excrement treatment capacity is improved, the fermentation operation efficiency is improved, the service life of the padding is prolonged, and the fermentation quality of an organic fertilizer is improved.

The invention relates to a flow-guiding purifying system for artificial lake water and a construction method thereof. The flow-guiding purifying system comprises a first gabion flow-guiding dam arranged around a lake inlet in the artificial lake water; the artificial lake water is divided into a water inlet region and a purifying confluent region by the first gabion flow-guiding dam; aquatic plants are planted in the purifying confluent region; the first gabion flow-guiding dam comprises a dam body arranged on the bottom of the artificial lake water and a downstream slope arranged on the downstream side of the dam; a water permeable material layer is arranged on the slope surface of the downstream slope; rock ballasts are filled between the slope surface of the downstream slope and the dam; the dam is formed by piled gabions; the gabions include gabion nets on an exterior frame, soil bags filled in the gabion nets and water purifying fillers filled in the soil bags. The flow-guiding purifying system for artificial lake water is capable of boosting the circulation of the artificial lake water in the whole lake area, purifying water, reducing energy loss and enhancing the landscape effect of the artificial lake.

The invention discloses bacillus licheniformis for decomposing feathers of pigeons. The bacillus licheniformis is classified and named bacillus licheniformis; the strain number is NJ-01; the bacillus licheniformis is preserved in the China Center for Type Culture Collection on Oct.23th, 2013 with the preservation number of CCTCC NO: M2013489. The invention also discloses application of the strain. The new strain disclosed by the invention can be directly used for decomposing the feathers of pigeons, so that waste of the pigeons can be recycled favorably, and ecological and circulating breeding of the pigeons is promoted; the bacillus licheniformis belongs to a safe microorganism and can be used in the fields of decomposition of the feathers of the pigeons, fermentation of meat pigeon breeding waste and biological fertilizers.

The invention belongs to the field of water and soil loss management and ecological environment restoration, and particularly relates to a technical method for projects, soil fertilizers, plants and agriculture and the like, which is a new water and soil loss management mode with very strong capability of water and soil conservation and ecological restoration and capability of organically combining a complete rainfall infiltration project with a simple and efficient soil fertility cultivation measure through distributing horizontal jumping ditches in a high-density way, centered on improvement of soil fertility for water and soil loss characteristics.

The invention discloses a method for constructing an ecological zone close to the natural complex waterfront by using the combination of silt / waste residue, 1) making a water filter cofferdam on the periphery of the conversion ditch, making an ecological concrete protective enclosure and planting wet plants on the outside of the cofferdam; Sludge pretreatment; 3) Throw the silt into the cofferdam, then insert a biodegradable filter planting filler tube into the silt and plant plants; 4) During the placement of the silt clumps, part of the silt seepage flows out through the cofferdam and passes through the wet The raw plants are filtered and purified; part of the silt seeps into the planting filler tube and then pumped away; 5) As time goes by, the sludge gradually dries up, and the biodegradable filter planting filler tube gradually degrades, and the plants grow rapidly to cover the entire transformation ditch. The invention solves the problem of nearby disposal of dredging sludge, and at the same time solves the problem of resource utilization of other industrial waste residues, forms a near-natural complex water bank ecosystem, and greatly improves the ecological and landscape functions of the river bank.
