Abstract
The invention provides a kind of method that use litter extract solution regulates and controls psilium succession, the method includes extracting grassland litter, and spray application on meadow leaching liquor, regulation and control of the litter extract solution to psilium succession are realized, so as to reach the reasonable utilization on meadow.
Description
Technical field
The present invention relates to grassland ecology technical field, drilled more particularly, to one kind litter extract solution regulation and control psilium
The method replaced.
Background technology
Grassland ecosystem is one of most important ecosystem-type, the normal performance of its function in terrestrial ecosystems
There is extremely important effect to maintaining the whole world and the regional ecological balance.Because the mankind are to the irrational utilization of natural resources
And the change of the environmental condition such as weather, ecology of grassland goes from bad to worse, and for desert steppe, the ecosystem is extremely crisp
Weak, due to inadequate natural endowment, in addition overgrazed, the denudation causes China's desert steppe large area to be degenerated, and desertifies and saline and alkaline
Change, in recent years, with the implementation of the great ecological engineerings such as conceding the land to forestry and grass and closed pasture, desert steppe is gradually controlled
Reversing occur in reason and recovery, ecological environment, and its core is by litter accumulation, covering and converts the soil moisture and nutrient that promote
Improvement, desert steppe Litter Layer is loosely organized, can effectively mitigate direct splash erosion of the raindrop to ground, can also intercept day
Right precipitation, makes soil water evaporation, increases soil moisture content, with important water conservation and water and soil conservation function.
Litter is the tie for connecting plant and soil in Grassland ecosystems, the self-holding core of Grassland ecosystems be by
The improvement of soil moisture and nutrient that litter coverage and decomposition bring, so that Productivity is improved, grassland degeneration situation
Alleviate, it is relatively early that the external research on litter is carried out, be initially that since forest ecosystem, Brary is equal to 1964
Forest Litter accumulation quantifier elimination has been carried out, important function of the litter in forest ecosystem, achievement in research has been discussed
So far be still cited, research of the China to litter is started late, progressively launch until the eighties in 20th century, mainly with forest,
Based on the research of Steppe litter.On the internal relation that meadow litter and soil nutrient are circulated, China is tender to pine flat
The region correlative study such as original is more, studies less to desert steppe, and desert steppe is compared with other Types of Grassland, and the ecosystem is more crisp
It is weak, desert steppe litter is goed deep into, systematic research, with extremely important and urgent realistic meaning.
The content of the invention
It is an object of the invention to provide a kind of method that use litter extract solution regulates and controls psilium succession, the method can
Realize the reasonable utilization to meadow.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of method that use litter extract solution regulates and controls psilium succession, the method includes soaking grassland litter
Carry, and leaching liquor is sprayed application on meadow, realize regulation and control of the litter extract solution to psilium succession.
Preferably, the method specifically includes following steps：
(1) species or composition of litter are determined；
(2) litter is collected in herbage withered and yellow phase, after natural air drying, crushes powdered storing for future use；
(3) a certain amount of litter powder, plus distillation flooding, filtering are weighed, Aqueous extracts mother liquor is obtained, is protected in 4 DEG C of lucifuges
Deposit；
(4) Aqueous extracts mother liquor is diluted, is sprayed application on meadow.
Preferably, the grassland is the grassland in Grazing Ecological Systems.
Preferably, the grassland is Alpine meadow.
Preferably, the litter includes grass family, sedge.
Preferably, the litter also includes composite family, pulse family, the plant of Ranunculaceae.
Preferably, the time of step (3) described extraction is 45-50h, preferably 48h.
Preferably, the liquid that being filtered into described in step (3) will obtain after extraction filters 2 prepared water extractions through double gauze
Liquid mother liquor.
Preferably, the concentration after step (4) the Aqueous extracts mother liquor dilution is respectively 5%, 10%, 20%.
Beneficial effects of the present invention are as follows：
1. gather materials on the spot, it is simple and convenient；
2. after test material applies meadow, residue will not be to soil, meadow, and domestic animal etc. causes harm；
3. the amount of meadow litter can be controlled by controlling the conservative distribution of burden, make it that highest Ecological Effect is reached to meadow
Should.
Specific embodiment
In order to illustrate more clearly of the present invention, with reference to preferred embodiment, the present invention is described further.Ability
Field technique personnel should be appreciated that following specifically described content is illustrative and be not restrictive, and should not limit this with this
The protection domain of invention.
It is most universal grassland utilization to herd, most economical Land use systems.Litter is main as soil-careless interface process
Medium, is the key factor for regulating and controlling ground-underground ecological process, and it is the important ecological process of material circulation that it is accumulated with decomposition,
Influence Productivity, bio-diversity, the recovery on degeneration meadow etc..The behavior manipulations such as feeding, trample, the excretion of domestic animal withered
The accumulation and decomposition of junk, and it is closely related with grazing intensity, system, season, domestic animal species.Different grassland, litter life
Yield is different, and the ecological effect that it is produced is different.At present, most methods are to eliminate rodent by applying fertilizer, cutting weeds, spray
The artificial compounds such as the agricultural chemicals of animal and insect regulate and control alpine meadow community function and structure, without to the spontaneous production in meadow
Material is rationally utilized, although be temporarily reached the purpose of regulation and control, but the sustainable use to grassland causes harm.
Inventor has found that one kind regulation and control psilium succession on the basis of meadow is developed in a healthy way, reaches sustainable use
Technology, be exactly to regulate and control psilium succession with the extract of grassland litter.
Litter Aqueous extracts are prepared, following steps are specifically included：
Step 1. determines the species or composition of litter；
Step 2. collects litter in herbage withered and yellow phase, after natural air drying, crushes powdered storing for future use；
Step 3. respectively weighs a certain amount of litter dry powder every time, plus distilled water is configured to required Cmax
Leaching liquor, is shaken up after 48h is extracted at room temperature through fully shaking, and leaching liquor is placed in volumetric flask after filtering 2 times through double gauze,
The leaching liquor of required concentration is made, 4 DEG C keep in dark place；
Step 4. before experiment, after the leaching liquor of preservation is fully mixed, takes concentration known leaching liquor, plus distillation moisture every time
The leaching liquor of other mass fractions is not diluted to, is uniformly sprayed application on meadow.
Litter Aqueous extracts prepared by the above method are applied to all Grazing Ecological Systems.
The present invention is suitable for all Grazing Ecological Systems, for reasonable utilization the on meadow provides scientific and effective method, together
When, also for the sustainable grazing management in meadow provides scientific basis, this is dynamic for the stabilization between foundation soil-grass-poultry, improves grass
Ground ecosystem service function has certain directive significance.
Specific operation of the invention is in Alpine meadow, in certain survey region, according to research area's average annual precipitation
