Description

A kind of feature flowers and trees cultivation substrate

Technical field

The present invention relates to a kind of feature flowers and trees cultivation substrate, specifically a kind of collection support plant root growth, association Adjust many Lifestyle factors of supply, mitigate the several functions such as continuous cropping obstacle and stubble-cleaning flowers and trees cultivation substrate.

Background technology

Substrate culture is referred in certain place or container to be fixed its root system by substrate and absorbs nutritional solution and oxygen Plant cultivation method.According to statistics, 90% soilless culture form is all substrate culture in the world.Soilless culture substrate is to be Plant provides the stable water coordinated, gas, the somatomedin of fertile structure, and it is in addition to support, fixed plant, it is often more important that serve as The carrier of nutrient and moisture, makes the nutrient and moisture from nutritional solution be able to transfer, and root system of plant therefrom selects to absorb on demand.Base Matter is the basis of soilless culture and core.So, the selection of substrate is the key for cultivating success or not.For each of soilless culture Planting base Quality Research progressively becomes the comprehensive problem of the subjects such as agronomy and gardening.With deepening continuously for research, early stage is big Scale using various inorganic and organic substrate gradually show its shortcomings and limitations, new feature organic culture substrate Start appearance and good characteristic is shown in utilization, become the developing direction of substrate research and development.

Cultivation matrix the most frequently used at present is mainly the inorganic matrixes such as Vermiculitum, perlite and rock wool, and peat（Also known as grass Charcoal）Deng organic substrate.The high water retention property of expanded vermiculite and laminated structure, coordinate air and water balance in substrate, together When have and fixed support plant, various effects such as plant nutrient, water conservation, fertilizer conservation and improvement substrate physical behavior are provided.Perlite Many hollow billet spaces and ventilation space of its particle surface keep moisture and nutritional labeling to provide huge surface area for which, together When also provide extremely suitable drain and ventilation condition.Rock wool quality is loose, permeability good, is permitted in the world today More national wide variety of cultivation matrix.Peat is not only loose porous, with preferable ventilating permeable and larger specific surface Product, it is also strong with abundant fiber content, stronger absorption and sequestering power, and higher ion exchange and salt balance control Ability processed, also has enhancing plant drought, disease-resistant, low-temperature resistance, the performance of salt resistance stain concurrently, is even more widely used.These substrate can To be used alone, it is also possible to be used in mixed way according to certain ratio.

Although above substrate have many advantages, but has its respective shortcoming.As Soilless culture need to add nutritional solution, and mud Charcoal is non-renewable resource of limited amount and short-term etc..Since the later stage eighties in last century, American-European countries promulgates in succession Relevant environmental regulation is implemented, is such as forbidden the discharge of nutritional solution in order to avoid impurely descending or earth surface water source, is forbidden opening for mud and charcoal Adopt, promote soilless culture progressively to environment-friendly type, economical, poly-talented direction transformation.

The deficiency of existing HUAMU substrate on market：On market, existing HUAMU substrate is often because causing itself and underlay soil It is hardened, permeability is bad, nutrient balance be deteriorated, shock-absorbing capacity diminish, be unfavorable for promote seedling growth, when serious even Cause plant to show nutritional deficiency symptom and some other physiological disease, affect the performance of substrate culture superiority.Due to more frequently Numerous irrigation, the various nutrients of Medium Culture are easy to be lost in into surface water or subsoil water, pollute environment.Most substrate are even After continuous use, can also cause microbial diversity decline, self regulation and repair function decrease, harmful microorganism amount reproduction, Cause plurality of plant diseases, endanger nursery stock normal growth.

The content of the invention

The technical problem to be solved in the present invention be to provide a kind of collection support plant root growth, coordinate many Lifestyle factors of supply, Mitigate the several functions such as continuous cropping obstacle and stubble-cleaning flowers and trees cultivation substrate.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of feature flowers and trees cultivation substrate, its Innovative point is：It is made up of the composition of following components：

80 parts of earthworm excrement, organic 35 parts of fertilizer that becomes thoroughly decomposed, 20 parts of peat, 15 parts of edible fungi residues, 10 parts of slow releasing agent, plant growth inhibitor 0.005 part, 0.003 part of plant growth control agent.

It is an advantage of the current invention that：Lumbricuss promote the nutrients such as carbon, nitrogen phosphate and sulfur to follow by the decomposition and inversion to organic substance Ring, increases organic materials nutrient supply and by the improvement to its structure, coordination, and preferably meeting the various of plant growing will Ask；Lumbricuss have surprising phagocytic activity, and several times of its day amount of eating up to its body weight, digestive tract can extracellular proteinase, fat Various enzymes such as enzyme, cellulase, chitinase, amylase, decomposition of these enzymes to most organic wastes have stronger Biocatalysis；After organic substance is ingested by Lumbricuss, small part is utilized by directly assimilation, the mill in most of Jing Lumbricuss body Discharged with graininess after broken and squeezing action, function similarly to the effect of extruder grain, so as to reach the purpose of physical modification；Together When, in Lumbricuss body cavity, microbe species are various, active very high, accelerate dividing for Organic substance with the synergy between intestinal secretion thing Solution and conversion, the earthworm excrement of generation have very strong absorbability, produce during effectively removing or suppressing organic materials composting Foul smell；Additionally, Lumbricuss metabolic activity can also produce a large amount of bioactive substances, may advantageously facilitate plant growth, strengthen crop Resistance and improve crop quality.
