Improved animal feeds and/or waters are provided, which include amendments comprising one or more copolymer salts serving to reduce volatilized ammonia derived from the excrement of animals. The copolymers are preferably water soluble and have substantially equimolar amounts of maleic and itaconic moieties.

Animal feed and/or water amendments for lowering ammonia concentrations in animal excrement

The invention relates to a floating two-stage osmunda japonica spore growing method. The floating two-stage osmunda japonica spore growing method is characterized in that the floating two-stage osmunda japonica spore growing method includes the following operation steps: (a) building of a seedling-growing greenhouse; (b) arrangement of floating water ponds; (c) making of floating trays; (d) loading and seeding; (e) post-seeding management; (f) preparation of a transplantation room and a temporary seedbed for two-stage seedlings; (g) temporary planting; (h) seedbed management. The floating two-stage osmunda japonica spore growing method has the advantages that the labor intensity is decreased, and the management is convenient; the seedling-growing period is shortened, so that seedlings can be transplanted into large fields from the nursery earlier; large-scale popularization and the progress of osmunda japonica industrialization are benefitted; and wild resources are protected.

Improved, low-cost agricultural products are provided comprising respective amounts of humic acid and a polyanionic polymer. The products may be mixed with or applied to fertilizers to enhance plant uptake of nutrients. The polyanionic polymer preferably includes maleic and itaconic repeat units, and optionally sulfonate repeat units.

Polymer soil treatment compositions including humic acids

Methods are provided for the treatment of livestock or poultry confinement facilities equipped with manure collection zones (e.g., a manure pit or litter), in order to reduce and mitigate the effects of gaseous ammonia within the facility. The treatment involves application of an aqueous mixture including a partial calcium salt of a maleic-itaconic copolymer and a partial ammonium salt of a maleic-itaconic copolymer. Preferably, the amount of the partial calcium salt copolymer is greater than the amount of the partial ammonium salt copolymer. The treatment methods provide prompt and lasting reductions in gaseous ammonia within the confinement facility.

Method of reducing atmospheric ammonia in livestock and poultry containment facilities

The invention relates to a selenium enrichment camellia oleifera tree interplanting method which refers to the method for jointly planting vetch and camellia oleifera trees in a mountain slope forest land. The method specifically comprises the steps that the mountain slope forest land is transformed through improved soil rich in organic selenium, land preparing, planting, pruning and fertilizer applying are carried out, survival sustaining is carried out in the first year of the camellia oleifera trees, and lower-concentration fertilizer pouring and complete flower thinning need to be carried out; sound seedlings are sustained in the second year, and accelerating nitrogen fertilizer needs to the applied before shoots bud; yield maintaining is carried out in the third year and the years afterwards, and the application amount of organizer fertilizer and phosphorus-potassium fertilizer needs to the increased. By means of the interplanting the camellia oleifera trees, the high yield of a single camellia oleifera tree can be achieved, and the economic benefits of agriculture and forestry planting can be improved.

The invention relates to a method for planting mikan vegetable, wherein it comprises that: transplanting, watering, fertilizing. And the invention is characterized in that: at each spring, transplanting wide mikan vegetable in the acid soil whose height is more than 650m, pH is 5.5-6.5, effective lead content is lower than 15 mug/g, and fertilizes at least 2000Kg in each field; the seed distance is 35-45cm, the row distance is 20-30cm, watering one time in transplantation; when the seed grows to 20-30cm, 45-55cm, and 70-80cm, watering, fertilizing at least 80Kg each field. After three years, the mikan vegetable will have developed root, strong branch and high yield as two harvests annually and 400-500Kg each field.

The invention discloses a microbial filler, and a preparation method and application thereof. The microbial filler is a composite-microbial-inoculant-carried fly ash nano modified filler. The fly ash nano modified filler is prepared by the following steps: by using fly ash and coal gangue as raw materials, adding auxiliary materials, adding nano Al2O3 as a nano modified filler, and firing. The composite microbial inoculant comprises Bacillus subtilis, Bacillus megaterium, nitrococcus, microzyme and lactobacillus. In the microbial filler, the microbial inoculant and modified filler have favorable synergistic actions; harmful substances in the sewage can be effectively removed by utilizing the adsorption characteristic of the filler and the degradation characteristic of the composite microbial inoculant; and thus, the microbial filler especially has excellent treatment effects on sewage containing rich organic substances, such as cultivation farm sewage, and implements harmless treatment and reduction on the sewage. Besides, the treated microbial filler can be used as a high-quality biofertilizer, and thus, does not have secondary pollution.

Microbial filler, and preparation method and application thereof

The invention discloses a leavening for cultivating earthworms and a method for cultivating earthworms. The leavening is prepared from fresh cow dung, rice straw and corn straw in parts by weight according to a ratio of 6:2:2 by virtue of mixing and fermenting. The leavening is obtained by respectively adding 35-45mL of EM bacterium solution with a mass percent of 10 percent in each kg of mixture of the fresh cow dung, the rice straw and the corn straw while fermenting for the first day, turning for a first time and turning for a second time by virtue of conventional natural piling and fermenting for 15 days. The fermentation time is short, and the fermentation is relatively full, and the leavening has no smell. The earthworms cultivated by applying the leavening are relatively high in nutritive value.
