The invention relates to a biochar-based fertilizer for restoration of heavy metal contamination of arable soil. The biochar-based fertilizer is composed of, by mass, 50% of biochar, 15% of micropowder of water-chilled dreg from a blast furnace, 30% of fresh cow dung and 5% of a composite biological inoculum. As the biochar and the micropowder of water-chilled dreg from the blast furnace undergo strict screening and effective component activation, the pH value of the soil is increased, the granular structure of the soil is improved, adsorption effect on heavy metal elements in the soil is effectively strengthened, and soil heavy metal restoration effect is enhanced; and in the composite composed by the biochar, the micropowder of water-chilled dreg from the blast furnace, the fresh cow dung and the composite biological inoculum according to a certain proportion, the biochar improves adsorption of heavy metals in a soil solution, the micropowder of water-chilled dreg enhances the silicon utilization rate of crops under the action of an activator, the crops prevent and control migration of heavy metals to the bodies of plants while absorbing silicon so as to reduce heavy metal content in the crops, and the biochar and the micropowder of water-chilled dreg have synergistic interaction in controlling of absorption of heavy metal elements in the soil by the crops.

The invention discloses a corn multifunctional composite drought-resistant water retention agent and a preparation method thereof. The water retention agent is made from corn flour, polyacrylic acid, polyglycol, an adhesive agent, a salt compound, microelements, agricultural boric acid rare earth and a plant growth regulator which are prepared according to a certain proportion. The preparation method comprises the following steps that: (A) the corn flour and water are added in a container; (B) pasting is carried out at a certain temperature; (C) polyglycol, polyacrylic acid and adhesive agentare added and mixed after pasting so as to generate a gelatinous material; (D) the gelatinous material undergoes reaction in nitrogen gas and then is neutralized by calcium hydroxide; and (E), through graft copolymerization, explosive polymerization, cooling, slicing, drying and crushing, a natural macromolecular graft copolymer is obtained, and then a salt compound, microelements, agricultural nitric acid rare earth and a plant growth regulator are added to carry out crushing and mixing, thereby generating a mixture. The corn multifunctional composite drought-resistant water retention agent has quick water-absorption speed, strong water-absorption capacity, easily implemented method, simple technical process and convenient operation, and is suitable to be used in production in small and medium-sized enterprises.

The invention relates to a pot-planting method for wolfberry, in particular to a pot-planting method for Ningxia wolfberry. The pot-planting method comprises the following steps: selecting a variety; selecting a seedling; preparing a pot-planting medium; planting the seedling; performing cultivation and management; training and pruning; preventing and controlling plant diseases and insect pests; selling in a market and the like; the pot-planting method further comprises the specific management methods of implementing fertilizer and water management measures, implementing a growth period pruning measure for delaying the fruiting period of budding seats, implementing an overwintering measure of a pot tree and the like. Through a wolfberry pot-planting technology provided by the invention, the fruiting period of the budding seats can be brought forward or delayed; in a facility cultivation environment in a northwest region, pot-planting wolfberry can be planted in late October; the fruit matures in mid-to-late February; the pot-planting wolfberry appears on the market 4 months earlier than outdoor wolfberry; the pot-planting wolfberry is planted in the beginning of May and the fruit matures in the end of October; the marketing period of fresh wolfberry is delayed to December. Through the wolfberry pot-planting technology, a wolfberry tree shape for ornamental and production can be cultured.

The invention discloses a viscosity reducing method for freezing method nitrophosphate neutralized slurry. According to the viscosity reducing method, on the basis of the freezing method nitrophosphate technological process, a resin exchange procedure is added for removing metal ions of calcium, magnesium, aluminum and iron in defluorinated mother liquor, and the purpose of reducing the viscosity of the neutralized mother liquor slurry is achieved. Through the method, the viscosity of the neutralized slurry is reduced, the cost is low, operation is simple, secondary pollution is avoided, obtained products are good in physical and chemical property, high in water solubility and wide in application range and meet the integration demand of water and fertilizer.

The invention discloses a compound microbial preparation with a deodorization function. The compound microbial preparation comprises components in parts by weight as follows: 30-60 parts of chlorite schist powder, 6-9 parts of magnesium sulfate, 3-6 parts of cane molasses, 20-28 parts of potassium oxide powder, 5-15 parts of sawdust, 1-3 parts of shell ginger powder, 2-4 parts of mulberry leaf powder, 0.3-6 parts of a beef extract, 0.5-0.8 parts of gel, 4-8 parts of dextrin, 1-3 parts of amino acid, 8-12 parts of cellulase, 3-12 parts of protease, 12-20 parts of a compound microbial agent and 50-80 parts of water. Through skillful combination of specially prepared filler with the compound microbial agent, microorganisms as well as malodorous gas ammonia and indoleamine gas can be converted into amine salt, not only is fertilizer increased, but also odor of a bio-toilet is reduced greatly.

The invention discloses a method for improving washed soil, and relates to a method for improving soil. The method for improving washed soil comprises the following process: determining the proportion of sand granules of 0.025mm of washed soil according to a hydrometer method, when the proportion of sand granules greater than 0.025mm of the washed soil is 60%-80%, the additive amount of mushroom residue composite additives is 8wt%-10wt%; when the proportion of sand granules greater than 0.025mm of the washed soil is 40%-60%, the additive amount of mushroom residue composite additives is 3wt%-5wt%, and when the proportion of sand granules greater than 0.025mm of the washed soil is below 40%, the additive amount of mushroom residue composite additives is 1.5wt%-2.5wt%; and mushroom residue composite additive is formed by uniformly mixing mushroom residue after decomposition treatment, biogas residue and fulvic acid according to the mass ratio of 355:97:38. The method not only can be used for increasing the water retaining capacity of the washed soil, but also can replenish nutritional ingredients of the washed soil, meanwhile, is low in cost, has no engineering modification, and is high in feasibility in actual applications.
