The invention discloses a deep-ploughing-free compound microbial fertilizer, and each ton of the fertilizer contains 10-25 kg of polyacrylamide, 10-30 kg of bacillus subtilis, 5-25 kg of streptomyces microflavus, 5-20 kg of bacillus laterosporus, 1-4 kg of diethylaminoethyl hexanoate, 20-50 kg of a polyaspartic acid, 5-25 kg of EDTA (Ethylene Diamine Tetraacetic Acid), 10-30 kg of urea, 5-20 kg of potassium humate, and the balance of organic filler. The fertilizer disclosed by the invention is high in microbial activity and strong in biological stability, can be used for effectively improving the soil aggregate structure, eliminating the soil hardening, enhancing the infiltration capacity of soil, and improving the cushioning properties of soil, and can be used for alleviating the damages on crops caused by soil secondary salinization due to excess fertilization; and the fertilizer disclosed by the invention also can be used for promoting the growth and development of beneficial microorganisms in the soil, thereby improving the utilization rate of the fertilizer and promoting the root growth of crops, so that roots are developed, the disease resistance of crops is enhanced, and the yield-increasing effect is obvious.

The invention discloses a compound fertilizer, which consists of the following raw materials: 6 percent of fulvic acid, 0.5 percent of magnesium sulfate, 0.5 percent of ferrous sulfate, 1 percent of zinc sulfate, 2 percent of ammonium sulfate, 0.5 percent of manganese sulfate, 0.2 percent of ammonium molybdate, 1.2 percent of borax, 6 percent of superphosphate, 25 percent of polypeptide urea and 15 percent of potassium sulfate. The compound fertilizer has the advantages of adjusting too low or too high soil acidity or alkalinity, resisting salinity and alkalinity, improving hardened soil, promoting the growth of crops, improving disease-resistant capacity of the crops, resisting lodging, resisting continuous cropping, resisting plant diseases and insect pests, resisting freeze injury, protecting soil against water loss, improving drought resistance capacity, improving the yield of the crops, improving the quality of the crops, vegetables, melons and fruits, improving the original quality and taste of the vegetables, melons and fruits, and prolonging the refreshing time thereof.

The invention relates to a method for preparing a soil conditioner of saline-alkaline soil, in particular to a method for preparing a soil conditioner of saline-alkaline soil. The soil conditioner is prepared by the following steps of: inoculating BM microbial inoculums into base materials, fungi and additives, which serve as raw materials, and performing heap fermentation, wherein the mass ratio of the base material to the fungus to the additive is 70-80:15-20:5-10. By the soil conditioner prepared by the method, the physical and chemical properties of saline-alkali soil can be improved, the fertilizer efficiency of the saline-alkaline soil can be enhanced, nutritional substances can be provided for edaphon, soil-borne insects and diseases can be inhibited, and utilization rate of fertilizer can be improved.

The invention discloses a lightweight matrix for sky-rise greenery and belongs to the technical field of gardening. The lightweight matrix is prepared from a material mixture of vinegar residue, cassava residue and crop straw powder which are subjected to fermenting and composting, minced coco coir, plant ash, peat and pearlite and is characterized by being prepared from the ingredients in parts by volume: 3-6 parts of vinegar residue, cassava residue and straw powder mixed organic fermented material, 1-2 parts of minced coco coir, 1-2 parts of plant ash, 1-2 parts of peat, 0.5-1 part of pearlite and a ternary compound fertilizer, of which the weight is 0.2-0.5% of the total weight; the matrix has the characteristics that the grain size is not greater than 5mm, the moisture content is 35-50%, the total porosity is 65-75%, and the volume weight is 0.35-0.5g / ml; in a dry matrix, the content of organic matters is not lower than 30%, the content of total nutrients is 2-3%, the EC value is 1.0-2.0sM / cm, the gas-water ratio is 1:(2-4), and the pH is 5.5-7.0; the matrix is granular solid, of which the appearance is dark-brown or black-brown, and is odorless. The lightweight matrix disclosed by the invention is loose in texture, light in specific weight and high in nutrient and is very applicable to the sky-rise greenery, such as urban primary road guardrails and pedestrian overpasses.

The invention discloses a fly ash-based soil water-retaining conditioner and a preparation method thereof, belonging to the technical field of soil water-retaining conditioners. The fly ash-based soilwater-retaining conditioner comprises fly ash clinker and a soil composite mineral type conditioner. The fly ash clinker is prepared from the following components in parts by mass through a calciningprocess, and the mass ratio of fly ash to calcium oxide or calcium carbonate to sodium carbonate to potassium carbonate is 1: (0-1) or (0-1.4): (0-0.5): (0-0.5). Through the water absorption and drainage principle of the generated dicalcium silicate, the effect of keeping moisture in the soil is achieved; the soil composite mineral conditioner is composed of humus soil, humic acid and cured pig manure, and can improve physical, chemical and microbial reactions of soil and increase fertility of the soil.

The invention discloses a biological soil conditioner. The biological soil conditioner is prepared from, by weight, 5-10 parts of plant ash, 40-60 parts of biological straw, 20-40 parts of organic materials, 5-25 parts of humic acid, 3-6 parts of biological active enzymes, 2-10 parts of biological strains, 5-15 parts of ammonia fertilizer, 1-5 parts of trace elements and 3-15 parts of animal faeces. According to the biological soil conditioner, the biological straw and the organic materials are adopted as composting materials, the strains are added for preparing fermented compost, the biological soil conditioner can effectively improve soil properties, improve soil organic matter, increase the crop yield and improve the crop quality, the cost is low, and the preparation technology is simple.
