The present invention provides a method for preparing compounded type humic acid water-retaining agent. Said method includes the following steps: adopting acrylic acid, starch and potassium hydroxide as main agent, compounding humic acid protective function group, controlling by items, respectively modifying and improving humate and potassium polyacrylate water-absorbing resin to make both them have reaction activity, then uniformly mixing them, and under the condition of heating and melting them making them implement compounding reaction so as to obtain the invented water-retaining agent with the function of promoting plant rooting, germination and growth.

A novel cell suited for mass production of Hemagglutinating Virus of Japan (HVJ), a method for obtaining the cell and use of the cell are disclosed. The human cell is originated from a transformed human kidney cell line, the doubling time thereof in logarithmic growth phase in suspension culture in a serum-free medium is not more than 40 hours, the cell has a freeze-recovery property, the maximum density of viable cells in suspension culture is not less than 106 cells / mL, and HVJ can grow in the cell. The method for obtaining the human cell comprises the steps of suspension-culturing a human transformed kidney cell line in a serum-free medium, and cloning the grown cells; and selecting, from the cloned cells, a cell whose doubling time in logarithmic growth phase in suspension culture in a serum-free medium is not more than 40 hours, which has a freeze-recovery property, whose maximum density of viable cells in suspension culture is not less than 106 cells / mL, in which HVJ can grow.

The invention discloses a soft PVC (Poly Vinyl Chloride) plasticizer prepared from the following components in parts by weight: 10-20 parts of fatty acid methyl ester, 20-30 parts of epoxy fatty acid methyl ester, 5-8 parts of benzoic acid, 5-10 parts of ethylene glycol, 3-5 parts of carbonyl diamine, 5-8 parts of soluble polyvinyl alcohol and 2-6 parts of epoxy soybean oil. The soft PVC plasticizer disclosed by the invention has the advantages of no toxicity, environment friendliness, good compatibility with PVC resin, high plasticizing efficiency and favorable durability.

The method for treating wastewater, comprising treating wastewater in an anaerobic zone to remove organic matter from the wastewater in an anaerobic zone to remove organic matter from the wastewater and to form granules of a biomass; transferring wastewater effluent from the anaerobic zone to an aeration zone; treating the wastewater effluent with a source of oxygen and an activated sludge in the aeration zone to further remove organic matter from the wastewater effluent and to form additional activated sludge; and transferring a portion of the activated sludge from the aeration zone to the anaerobic zone.

The invention relates to a rivier giantarum rhizome pit planting method, and belongs to the technical field of crop cultivation. The method comprises the specific steps that 1, seeds are selected, wherein 100-250 g of rivier giantarum rhizomes with no scab or rot are selected as seed rivier giantarum rhizomes; 2, storage is carried out, wherein the seed rivier giantarum rhizomes are stored at the indoor temperature in a heat preservation mode after being dried in the sun; 3, grooves are dug, wherein land parcel outer edges are selected, and grooves are dug along the land edges; 4, backfilling is carried out, wherein the grooves are backfilled with straw and fine soil, and strip-shaped planting belts are formed through accumulation; 5, seeding is carried out, wherein seeding is carried out in mid-to-late April next year. By the adoption of the rivier giantarum rhizome pit planting method, the soil organic matter can be increased, the soil quality can be improved, the soil water permeability and breathability are improved, the development space is expanded, the problems that the rivier giantarum rhizomes have harsh requirements for land parcels and a few of appropriate planting areas exist are solved, and the purpose of controlling and relieving diseases and improving the yield of the rivier giantarum rhizomes is achieved. Chemical fertilizer and pesticide can be replaced, or the usage amount of chemical fertilizer and pesticide can be reduced, high yield and stable yield of the rivier giantarum rhizomes are achieved, and it is ensured that the product is environmentally friendly and safe in quality.
