Description
Technical field
The present invention relates to technical field of agricultural cultivation more particularly to a kind of nutrient matrixes and its system for Ornamental Bamboo cultivation
Preparation Method.
Background technology
Bamboo belongs to grass family (Poaceae) Bambusoideae (Bambusoideae) perennial evergreen plant, the whole world there are about
70 belong to more than 1200 kinds, are distributed mainly on Asia.Bamboo is the important component of the forest reserves, and China is the center producing region of bamboo
One of, the good reputation of " bamboo kingdom " is known as, either《The Book of Songs》In " order order this card, faint South Mountain " or Soviet Union and Eastern Europe slope it is " peaceful
Edible no meat, can not occupy no bamboo ", all it is seen that Chinese bamboo culture trace of long standing and well established.As bamboo resource in the world most
Abundant country, China have more than 500 kinds of bamboo class of category, bamboo grove Class area estimation more than 40 to have as many as more than 400 ten thousand hectares, be mainly distributed on China
Southern each province accounts for about the 3% of the national forest gross area, accounts for the 25% of world's bamboo grove gross area.With higher economic use value
Mao bamboon (Phyllostachys pubescens) woods have 2,800,000 hectares, account for 70% or so.
Bamboo is fast-growing type plant resources, and growth soon, is easily bred, the period is short, per unit area yield is high, and disposable cultivation is afforested, every year
Go out the long bamboo of bamboo shoot, become a useful person within 3 or five years, annual reasonable intermediate cutting can continuously utilize decades.Bamboo is with its unique biology, ecology
And the features such as multipurpose, the attention of people is increasingly subject to, is just being played in Sustainable Development Strategy of China more and more important
Effect.
However, the phenolic acid containing higher concentration in existing nutrient matrix, and photosynthetic rate of the phenolic acid to bamboo, chlorophyll
Content, cauline leaf growth, root system development and biomass accumulation etc. have inhibiting effect, are unfavorable for the growth and development of bamboo, and seek
Content of beary metal is big in foster matrix, be easy to cause the heavy metal pollution of soil.
Invention content
In view of this, the object of the present invention is to provide a kind of nutrient matrix and preparation method thereof for Ornamental Bamboo cultivation,
To reduce the content of phenolic acid in nutrient matrix, inhibition of the reduction phenolic acid to bamboo growth and development improves the survival rate that bamboo is cultivated,
The content of beary metal in nutrient matrix is reduced simultaneously, improves the feature of environmental protection of nutrient matrix.
The present invention solves above-mentioned technical problem by following technological means：
A kind of nutrient matrix for Ornamental Bamboo cultivation includes the raw material of following parts by weight：30~40 parts of dredging silt,
20~30 parts of bamboo shoot shell, 10~15 parts of cinder powder, 10~15 parts of fresh pig dung, 5~10 parts of rape cake, 5~8 parts of pine bark, concave convex rod
Stone clay/3~5 parts of chitosan particle.
In addition, the present invention also provides a kind of preparation method of the nutrient matrix for Ornamental Bamboo cultivation, including following step
Suddenly：
1) processing of raw material：Bamboo shoot shell, rape cake, pine bark are dried, then is crushed with pulverizer and crosses 120 mesh sieve, is obtained
Mixed-powder takes fresh pig dung to add in mixed-powder, is stirred evenly under the rotating speed of 300~500r/min, obtain fermentation material；
2) decomposed fermentation：1) fermentation material obtained in is poured into the porose fermenter in bottom, is uniformly blended into fermentation material
The zymophyte of 1.2% times of weight, then watering wetting fermentation material, makes fermentation material water content reach 75~80%, then at 45~55
15~20d of continuing fermentation at DEG C, obtains decomposed manure；
3) degradation of phenolic acid：2) decomposed manure that will be obtained in adds in the Fenton reagent of 2~3% times of weight of fermentation material,
It is uniformly mixed, 30~60min is reacted under room temperature；
4) preparation of nutrient matrix：First cinder powder, attapulgite clay/chitosan particle and dredging silt are uniformly mixed
It closes, the decomposed manure in then adding in 3) after the degradation treatment of phenolic acid, pH value is adjusted to 5~6, then at 40~50 DEG C
Drying is to get to nutrient matrix
Further, the zymophyte in step 2) includes EM bacterium, ferment bacterium and Gymboree zymophyte.
Further, during the decomposed fermentation in step 2), a stirring and moisturizing is carried out every 3~5d, keeps fermentation material
Water content 50~80%.
Further, the preparation method of attapulgite clay/chitosan particle described in step 4) is as follows：
Step 1, the activation of attapulgite clay：Attapulgite clay is taken, crush and crosses 120 mesh sieve, at 750 DEG C
1h is roasted, is cooled to room temperature, is then immersed in the hydrochloric acid of 10 times of volume 1mol/L, 3h is stirred at 80 DEG C, centrifugation goes demineralizing acid molten
Liquid, the multiple water of precipitation deionization rinse, then the precipitation after flushing is immersed the oxalic acid solution that mass fraction is 10%, in room temperature
It is lower to use supersonic oscillations 2h, it then filters except oxalic acid solution, the multiple water of precipitation deionization rinses, then dry in 110 DEG C
To activation attapulgite clay powder；
Step 2, the preparation of chitosan colloidal sol：Chitosan is taken to immerse the oxalic acid solution that 10 times of volume mass scores are 10%
In, it is fully dissolved under 50 DEG C of magnetic agitation, obtains chitosan colloidal sol；
Step 3, the load of chitosan：The chitosan colloidal sol that step 2 obtains is taken to add in isometric deionized water dilution,
The activation attapulgite that the step of being sufficiently stirred, obtaining chitosan colloidal sol dilution, take 6~10 times of weight of chitosan one obtains sticks
Native powder is added to chitosan colloidal sol dilution, then persistently stirs 5h, then stand 5h while stirring, removes supernatant, will be heavy
It forms sediment and pours into the NaOH solution of 5 times of volume 1mol/L, after stirring 30min under the rotating speed of 1500~3000r/min, it is molten to filter removal
Then agent, then rinsed with deionized water to neutrality is dried in vacuo to get to attapulgite clay/chitosan particle.
Further, the power of the ultrasonic wave in step 1 is 120W, frequency of oscillation 50kHz.
Further, the vacuum drying condition of step 3 is：Temperature 60 C, vacuum degree 0.09MPa~0.1MPa, time
20h。
Beneficial effects of the present invention：
1. the content of phenolic acid is low in nutrient matrix prepared by the present invention, the photosynthetic rate of bamboo, chlorophyll content, cauline leaf life
Long, root system development and biomass accumulation will not be suppressed, and the growth and development ability of bamboo is strong, the survival rate of bamboo cultivation
It is high；
2. prepared by the present invention, nutrient matrix water imbibition, water-retaining property are strong, can promote the water suction and development of bamboo root system, simultaneously
The light-weight of nutrient matrix, quality are loose, more convenient to be transported in packing box, promote the aerobic respiration of bamboo root system；
