The invention relates to an agricultural fertilizer, in particular to a microbial compound fertilizer and application thereof. The microbial compound fertilizer specifically consists of a zymophyte agent and a compound fertilizer, wherein each gram of the compound fertilizer comprises not less than 0.2*108 bacterial cells; the compound fertilizer comprises the following components in percentage by weight: 5 to 15 percent of farmyard manure, 10 to 30 percent of humic acid, 5 to 8 percent of grass carbonic acid, 15 to 30 percent of nutrient and the balance of boric sludge; and the zymophyte agent is obtained by fermenting silicate bacteria, azotobacter chroococcum, actinomycetes, saccharomyces cerevisiae and rhodopseudomonas sphaeroides, wherein the silicate bacteria, the azotobacter chroococcum, the actinomycetes, the saccharomyces cerevisiae and the rhodopseudomonas sphaeroides are mixed together in a weight fraction of 1:1:1:1:1. The microbial compound fertilizer acting on a big field can increase the yield of crops by 20 to 30 percent, and simultaneously can obviously increase the percentage of fertile fruits, reduce fruit dropping and overgrow the fruits; besides, the maturation stage is shortened by 5 to 7 days, the yield-increasing effect is obvious, and simultaneously, the microbial compound fertilizer can obviously improve the appearance, the mouthfeel, the color and luster and the like of products, improve the quality by 1 to 2 grades, and prolong the product freshness date.

The invention discloses an organic-inorganic compound fertilizer and a preparation method thereof. The organic-inorganic compound fertilizer comprises the following raw materials in parts by weight: 25-30 parts of green algae, 12-17 parts of humic acid, 7-12 parts of bagasse mortar, 8-12 parts of saw dust, 7-15 parts of vermiculite, 5-10 parts of filtration mud, 5-10 parts of yeast organic waste water concentrated liquid, 5-8 parts of cane slag, 2-5 parts of sugarcane top and 2-5 parts of microbial strain liquid. The amount of the compound fertilizer organic matter is large than or equal to 55 weight parts, the total amount of NPK inorganic matters is large than or equal to 12 weight parts, the amount of the moisture is less than or equal to 25 weight parts, the effective viable count is large than or equal to 2 hundred million / gram, and the pH is 5.0-8.5. The preparation method comprises the following steps: fermenting twice by using microbial strains; adding inorganic porosity vermiculite, evenly mixing, and naturally drying so as to obtain the organic-inorganic compound fertilizer. Biodegradable agricultural and industrial production waste water, waste slag and sugarcane top regeneration organic matters are fully utilized as the raw materials, thereby improving the acidity and basicity of soil, improving the cation exchange capability (CEC) of the soil, improving the utilization of fertilizer, promoting the growth of crop and increasing the yield of the crop. The organic-inorganic compound fertilizer has the advantages of good ecological benefits and circular economy benefits and can be used as an additional fertilizer for crops such as sugarcane, watermelon and the like.

The invention discloses a planting structure and a planting method thereof, aiming to solve the problem of water shortage for plant growth in arid regions and guarantee good plant growth and vegetation recovery in the arid regions. The planting structure comprises a planting pit and a planting soil layer in the planting pit. An impermeable film is arranged on the surface of the planting pit. An evaporation-resisting cover film is arranged at the upper end of the planting soil layer. A cover soil layer is arranged at the upper end of the cover film. By the planting structure, permeation and evaporative loss of moisture are remarkably reduced, rainwater collection, confluence and storage into the planting pit are facilitated, the planting pit can have sufficient moisture for plants to absorb, and accordingly, survival rate of planted plants is guaranteed. The planting method is simple in technology, low in cost and obvious in effect in the acid regions, and is of great significance in improving planting survival rate of plants in the acid regions and recovering vegetation.

The invention provides a biological organic / inorganic compound fertilizer. The biological organic / inorganic compound fertilizer contains 30-35% of total nutrients; the nutrient ratio of N to P2O5to K2O is (6-15) to (5-18) to (6-25); the living bacteria count in the bioactive organic insecticide-fertilizer is 50 million / g to 100 million / g; besides, the biological organic / inorganic compound fertilizer contains 15%-25% of organic matters, 0.15-0.20% of nicotine, less than or equal to 3.0% of chloride ions and less than or equal to 12% of moisture, has the fineness of 40-60 meshes and the pH of 6.0-7.0. The preparation method of the biological organic / inorganic compound fertilizer comprises the following steps: adding tobacco stems, cake meal, pig manure, artificial humic acid and a microbial fermentation agent to a mixer, adding water while mixing, and composting the materials for fermentation to obtain the fermented and decomposed materials; next, adding the fermented and decomposed materials, urea, ammonium dihydrogen phosphate, potassium chloride, active carbon nanopowder and a functional microbial agent to the mixer, mixing evenly and crushing, screening to obtain powder and packaging to obtain the biological organic / inorganic compound fertilizer which is high in content of nitrogen, phosphorus and potassium inorganic nutrients and organic matters, and has environment-friendly and insect-resistant effects.

The invention relates to the field of plant nutrient soil, and particularly relates to nutrient soil for a potted plant. The potting nutrient soil comprises the following active ingredients in parts by weight: 50-70 parts of needle-point leaf soil, 10-20 parts of chitosan, 5-10 parts of plant ash, 5-10 parts of pine bark, 1-3 parts of slaked lime, 10-20 parts of wormcast, 5-10 parts of river sand, 5-15 parts of bone meal, 2-5 parts of active microorganism, and 0.5-1.2 parts of liquorice. By adopting the technical scheme, the potting nutrient soil has the beneficial effects that the potting nutrient soil is rich in nutrient substances, good in water retention and nutrient preservation properties, good in soil permeability, and low in cost, potted plant can be directly placed in the potting nutrient soil for growth, the potting nutrient soil is high in nutrition value, rich in various mineral substances of calcium, phosphorus and the like, and can continuously provide nutrition. The potting nutrient soil is convenient to use, incapable of causing any environment pollution, good in solubility, popular with potted class, and has a broad market development space.
