The soil organism refers to organic compound carbon containing in soil.The soil organism essential element composition be C, O, H,
N accounts for 52%-58%, 34%-9%, 3.3%-4.8%, 3.7%-4.1% respectively.Followed by P and S, C/N ratio are 10 or so.
The effect of the soil organism:
The content and soil fertility level of the soil organism are closely related.Although organic matter only accounts for the very little one of soil total amount
Part, but it is significant that it plays various effects in soil fertility.Feelings usually same or similar in other conditions
Under condition, in certain content range, content and the soil fertility level of organic matter are positively correlated.
It folds and plant nutrient is provided:
Contain a large amount of plant nutrient, such as N, P, K, Ca, Mg, S, Fe important element in the soil organism, there are also some
Microelement.The soil organism discharges a large amount of nutrient through mineralization process and provides nutrient for plant growth;Organic matter
Humification process synthesizes humus, saves nutrient, and humus is again through mineralization process Releasing nutrient once again, to guarantee plant
Grow the nutrient demand of overall process.
The CO2 that the mineralization procedure decomposition of organic matter generates is the important sources of plant carbon nutrition, it is estimated that, soil has
The CO2 that the decomposition of machine matter and microorganism and root respiration generate, it is annual up to 13,500,000,000 t, it is roughly equivalent to land plant
Requirement.It can be seen that the CO2 that the mineralization process of the soil organism generates is both the important sources of CO2 in atmosphere, and plant
Object light is closed and the important carbon source of effect.The soil organism or the most important nutrition library of soil N, P, are plant quick-acting N, P
Main source.The 92%-98% of soil total N is the organic N stored in the soil, and organic N is concentrated mainly in humus, one
As be the 5% of humus content, it was found that it is from soil that the nitrogen of plant absorption, which has 50%-70%,.It is organic in the soil organism
The content of state P typically constitutes from the 20%-50% of total Phosphorus In Soil, releases rapid available phosphorus with the decomposition of organic matter, supplies plant nutrient.
In most of non-calcareous soils, organic sulphur accounts for the 75%-95% of full sulphur in organic matter, with the mineralization process of organic matter
And discharge, it is absorbed and used by plants.
During decomposition and inversion, the organic acid and humic acid of generation have soil mineral part certain the soil organism
Solvability can promote Mineral Weathering, be conducive to the validation of certain nutrients.Some gold being complexed with organic acid and fulvic acid
Belonging to ion can be retained in the soil liquid, will not precipitate and increase its validity.Certainization that agron and iron are formed
Object is closed, is effective to plant and microorganism in acid or basic soil.
It folds and promotes plant growth and development:
The soil organism has aromatic polynary phenol functional group, can reinforce plant respiration process especially with wherein humic acid,
Cell permeability of the membrane is improved, nutrient is promoted to quickly enter plant.The sodium salt of humic acid, which has plant root growth, to be promoted
Effect, experiment results proved natrium humate, which has the root growth and development of the gramineae plants such as corn and careless class, to be greatly facilitated
Effect.In the soil organism also containing vitamin B1, B2, pyrrole alkyd and niacin, hormone, different growth hormone (β-heteroauxin),
Antibiotic (streptomysin, penicillin) etc. plays a driving role to the growth of plant, and can enhance plant resistance to environment stress.
Fold the physical property for improving soil:
Organic matter is various improving the effect in soil physical properties, wherein the most important and direct effect is improvement
Soil texture, promotes the formation of crumbled structure, to increase the sponginess of soil, improves the aeration and water penetration of soil.
Humus is the main cementing agent of soil agreegate, and the humus in soil seldom exists with free state, most and mineral grogs
It is combined with each other, by mechanism such as function base, hydrogen bond, Van der Waals forces, mineral grogs appearance is coated in the form of glue film, is formed with
Machine-inorganic complex.It is formed by aggregate, it is preferably to tie that large and small hole distribution, which rationally, and has stronger water stability,
Structure body.The cohesive force of agron is stronger than sand grains, in sand loam soil, can increase the caking property of sand and promote pellet shape knot
The formation of structure.The cohesive force of humus is smaller than clay, generally the 1/12 of viscous force, and adhesion strength is the 1/2 of clay, when humus covers
Lid clay surface reduces the direct contact between clay, can reduce the cohesive force between clay, and the cementation of organic matter can be formed
Biggish aggregate further reduces the contact surface of clay, substantially reduces the viscosity of soil, therefore can improve clay
Soil tilth and permeability.Organic matter reduces the swell-shrink characteristic of soil by improving viscosity, and prevent from occurring when soil drought is big
Crack.
Agron is hydrophilic colloid, has huge specific surface area and hydrophilic radical, the according to surveying and determination water suction of humus
Rate is 500% or so, and the water absorption rate of clay mineral is only 50% or so, therefore, can improve the effect water capacity of soil, this is to sand
Soil has great significance.Humus is that brown is brown or atrament, keeps soil color dimmed after being surrounded by grogs, thus
The ability of soil heat absorption is increased, improves the soil moisture, it is especially important that this characteristic promotes seed to sprout the northern time in early spring.
Ratio of heat capacities air, the minerals of humus are big, and smaller than water, and thermal conductivity is placed in the middle, therefore, the high soil of soil organic matter content
Its soil moisture is relatively high, and luffing is small, good heat preservation performance.
The soil organism is the main source of nutrient needed for edaphon vital movement and energy.Without it there will be no
All Biochemical processes in soil.The population of edaphon, quantity and activity increase with the content of organic matter and are increased, tool
There is extremely significant positive correlation.The mineral rate of the soil organism is low, will not generate as fresh plant residuum to microorganism fast
Violent priming effect, but lasting stability to microorganism provide the energy.Therefore, rich in the soil of organic matter, fertility is steady
And the excessive growth and de- fertile phenomenon of plant are not easily caused persistently.
(such as earthworm) having in soil animal is also using organic matter as food and energy source;Organic mass-energy improves soil object
Environment is managed, porousness is increased and improves permeability (then reducing permeability for sand), to be the activity of soil animal
Good condition is provided, and soil animal itself accelerates the decomposition (decomposition of especially fresh organic matter) of organic matter.
Further improve soil permeability, creates good environmental condition for edaphon and plant growth.
Agron is a kind of colloid, there is huge specific surface and surface energy, and humus colloid is with negatively charged
It is main, so as to adsorb such as K+, NH4+ of the exchangeable cation in the soil liquid, Ca2+, Mg2+ etc., on the one hand can avoid with water
It is lost, on the other hand can be got off again by exchange and be utilized for plant absorption.Its fertilizer conservation performance highly significant.Agron and clay
Mineral are the same, have stronger adsorption capacity, but the ability of unit mass humus preservation cation nutrients is bigger than clay mineral
Several times to tens times, therefore, the soil organism has huge fertilizer-preserving ability.Humic acid itself is a kind of weak acid, humic acid and
Its esters may make up buffer system, buffers H+ concentration variation in the soil liquid, soil is made to have certain buffer capacity.It is more important
Be humus be a kind of colloid, there is stronger absorption property and higher cationic replacement ability therefore have soil
Stronger cushion performance.
Organic matter has the function of activating phosphorus:
Phosphorus in soil often exists generally not with the presence of quick-acting states to imitate state and slow state late.Therefore P availability in soil
It is low.The soil organism has characteristic with the phosphorus reaction of slightly solubility, can increase the solubility of phosphorus, to improve having for phosphorus in soil
The utilization rate of effect property and phosphate fertilizer.In addition, soil humic acid is proved to be a kind of physiological activator, it can accelerate seed to sprout,
Enhance root activity, promote plant growth, for edaphon, humic acid is also that a kind of physiology of enhancing development is living
Property substance.It must be noted that organic matter when decomposing, can also generate and some be unfavorable for plant growth or even harmful centre
Substance, especially under anaerobic condition, such case is easier to occur.
Increase and keep:
The soil organism is exactly that the warehouse of nutrient is provided for crop growth.It is the large family in soil nutrient.In addition, it
Or judge one of the important indicator of soil girth of a garment standard.So organic matter status in the soil and quantity, have to keep
One relatively stable number is better.The soil organic matter content in China, general nonirrigated farmland are 0.5%-3.0%, paddy field 1.5%-6.0%.
Because the decomposition and conversion of organic matter be ongoing, the soil organism is during growth and decline, soil fertility also phase
Change with continuous with answering.
