Summary of the invention

The present invention mainly is the defective that solves existing in prior technology matrix in bulk, has also avoided the pollution problem that brings to soil as binding agent, water absorbing agent with chemical reagent in the compact type substrate simultaneously.

Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: compressed type plant culture stroma is made up of fertilizer, binding agent, plant growth regulator, and described fertilizer comprises wooden nutrient, fertilizer, composite bacteria; Described binding agent is an attapulgite, and described plant growth regulator is a rare earth addition.

The composition proportioning of its each material of compressed type plant culture stroma is: wooden nutrient 40～50, fertilizer 20～35, attapulgite 25～30, composite bacteria 0.2～0.3, rare earth addition 0.2～0.3; Described wooden nutrient is the powder mixture of things such as dry fruit shell, vegetable fiber and timber bits; Wherein the dry fruit shell be in walnut shell, peanut shell, melon seed cases, the rice hulls any one, vegetable fiber is in reed rod, sedge, agricultural crop straw, corncob, bagasse, the bamboo shoot shell any one two kinds; Described composite bacteria is by actinomycetes, and bacillus breathes out time Trichoderma, saccharomycete, and lactic acid bacteria, azotobacter, phosphate solubilizing bacteria, potassium solubilizing bacteria is formed;

The processing step of compressed type plant culture stroma is with the wooden nutrient of 5～50 purposes, with fertilizer and composite bacteria, attapulgite, mixes and stirs, briquet.With 100 kilograms of compressed type plant culture stromas of every production is example, must be the wooden nutrients of 5～50 purposes with 40～50 kilograms of specifications, with 20～30 kilograms fertilizer, and 0.2～0.3 kilogram of composite bacteria, 0.2～0.3 kilogram rare earth addition mix, and stirs; Add 35～40 kilograms again and be crushed to 5～20 purpose peat, 0.2～0.3 kilogram composite bacteria, 30～35 kilograms attapulgite, mixing and stirring is sent into block-making machine compression moulding.During use, make matrix suck capacity moisture after, can recoil to predetermined porosity, satisfy in the plant strain growth process requirement to nutrient, air, moisture.

The used wooden nutrient of the present invention mainly is from plant duff and vegetable garbage, wherein contained composition has cellulose, hemicellulose, lignin, pectic substance, natural gum, tannin, protein, pigment, fat, resin, ribosome and several mineral materials etc., but main component is a cellulose, account for 40%～50%, lignin accounts for 20%～24%, hemicellulose (poly pentose and methyl poly pentose) accounts for about 20%, and protein accounts for 0.6%～1.88%.

The used fertilizer of the present invention is that pig manure, cow dung, chicken manure etc. are made through the hot fermentation time, the nutrient of the inside all can change into the state that crop can directly absorb, germ, worm's ovum and the grass-seed etc. that hide wherein be can also eliminate, assanation and people, animal health helped.

The present invention adopts attapulgite as binding agent, can make matrix degree of tightness appropriateness, is beneficial to plant strain growth, and it not only plays the curing molding effect, also has to prolong the function that keeps the fertilizer efficiency time and improve fixed carbon content, anti-rain drop erosion in the matrix.

The used composite bacteria of the present invention is by actinomycetes, and bacillus breathes out time Trichoderma, saccharomycete, and lactic acid bacteria, azotobacter, phosphate solubilizing bacteria, potassium solubilizing bacteria is formed, and main effect is a fixed nitrogen, and cellulose, hemicellulose and lignin are resolved into polysaccharide, is beneficial to plant absorbing.
