Description
Technical field
The present invention relates to bioassay technique field, more particularly to a kind of charcoal of analyzing is applicable the crop growth stage
Method.
Background technology
Charcoal be bio-organic materials (biomass) in anoxic or anoxybiotic environment, what is generated after high temperature pyrolysis consolidates
State product.The high-quality energy, soil conditioner are can not only be used for, can also be used as reducing agent, fertilizer slow release carrier and carbon dioxide envelope
Agent etc. is deposited, is widely used to carbon fixation and emission reduction, water source purifying, heavy metal adsorption and soil improvement etc., can be to a certain extent
The whole world hot issues deeply concerned such as climate change, environmental pollution and soil function degeneration provide solution.Charcoal can also carry
High agricultural productivity, reduce the demand to the intensive fertilizer of carbon.The pore space structure of charcoal particle very easily assemble nutriment and
Beneficial microbe, so that soil becomes fertile, beneficial to plant growth, agricultural is allowed to have more continuation while realizing volume increase.More
Wonderful, it is locked in carbon in biota, rather than allows it to be discharged into air.Biomass carbonated technology is generally acknowledged solution gas
Wait one of possible technique measure of variation issue, have raw material sources are extensive, production cost is low, ecological safety, it is pollution-free, can
The distinguishing feature such as it is widely applied.Charcoal caused by after biomass carbonated is applied to ecology and can subtracted with environmental area with carbon sequestration
Row, it is a kind of effective carbon remittance technology, is combined with agriculture, forestry can solve agriculture and forestry organic waste material pollution and be asked with greenhouse gas emission
Topic.Charcoal applies farmland, can be effectively improved soil physico-chemical property, increases crop yield, promotes agricultural sustainable development.Biology
Charcoal is a kind of economically viable mode of fixed carbon dioxide, not only have cured the carbon dioxide absorbed in trees and crop,
Its product " biological carbon " is stored in soil, and thousands of years all without changing, while producing regenerative resource, also improve
Soil fertility, improve crop yield.Charcoal can be embedded in discarded colliery, or place into the soil during cultivation.Charcoal is filled out
Bury to also help and improve drainage of soil system, and 80% or so such as nitric oxide and methane isothermal chamber gas are sealed up for safekeeping in soil
In earth, it is prevented to be discharged into air.
The crop growth stage is applicable also without unified analytical technology currently for charcoal, is only with plantation experience
Apply charcoal, the application effect for causing charcoal is played and do not come out by this, because the crops of different growth phases are to biology
The demand of charcoal is different, in order to improve the yield of crops, so, prior art proposes the applicability skill on charcoal
The research method of art, but analytical cycle length be present in this method, cumbersome, cost is high, and fluctuation is strong in processing procedure, is not easy
Control, gained applicability value is nonstandard, error is big, and crops are applicable therefore, being badly in need of exploitation one kind and can accurately analyze charcoal
The method of growth phase.
The content of the invention
Analytical cycle length existing for the method in crop growth stage is applicable in order to solve to analyze charcoal in the prior art,
Cumbersome, cost is high, is easy to error be present during analysis, the problems such as causing analyze data nonstandard, and the present invention provides
A kind of method analyzed charcoal and be applicable the crop growth stage.
Concrete technical scheme of the present invention is as follows：
The invention provides a kind of method analyzed charcoal and be applicable the crop growth stage, this method includes following step
Suddenly：
S1, soil are collected：Charcoal is uniformly applied into soil, is uniformly mixed charcoal with soil with cultivator,
Temperature is after being placed 3-5 days under 25-35 DEG C of ambient temperature, and the soil before collecting a box proportion of crop planting every 3 days is as soil
Earth sample 1,6 box pedotheques 1 are collected altogether, the weight per box pedotheque 1 is 30-40 grams, standby；
Sodium bicarbonate solution is separately added into S2, the 6 box pedotheques 1 collected into step S1, and vibrated successively,
Ultrasonic disperse, after centrifuging, obtain 6 box supernatants 1；
S3, the 6 box supernatants 1 obtained in step S2 are respectively placed in elemental analyser, and measured respectively in supernatant 1
The content of carbon, that is, carbon content corresponding to different sample times before proportion of crop planting is obtained, and draw out soil before proportion of crop planting
Carbon content standard curve；
S4, by proportion of crop planting in step S1 soil, after plantation 2-3 months, collected a box crops every 3 days
The soil of planting season collects 6 box pedotheques 2, the weight per box pedotheque 2 is 30-40 grams, standby altogether as pedotheque 2
With；
Sodium bicarbonate solution is separately added into S5, the 6 box pedotheques 2 collected to step S4, and is vibrated, surpassed successively
Sound is scattered, after centrifugation, obtains 6 box supernatants 2,6 box supernatants 2 are respectively placed in elemental analyser, and is measured respectively
The content of carbon in supernatant 2, that is, carbon content corresponding to difference sample time proportion of crop planting phase is obtained, and draw out farming species
Plant phase soil carbon content standard curve；
S6, after the crops planted in step S4 reach the maturity period, every the soil that 3 days collect a box crop maturity phase
Earth collects 6 box pedotheques 3, the weight per box pedotheque 3 is 30-40 grams, standby altogether as pedotheque 3；
Sodium bicarbonate solution is added in S7, the 6 box pedotheques 3 collected to step S6, and is vibrated successively, ultrasound point
Dissipate, after centrifugation, obtain the box supernatant 3 of 6 box supernatant 3,6 and be respectively placed in elemental analyser, and measure supernatant 3 respectively
The content of middle charcoal, that is, carbon content corresponding to difference sample time crop maturity phase is obtained, and draw out crop maturity
Phase soil carbon content standard curve；
The farming species that soil carbon content standard curve, step S5 are drawn before S8, the proportion of crop planting for drawing step S3
The crop maturity phase soil carbon content standard curve that plant phase soil carbon content standard curve and step S7 are drawn is through data analysis
Device carries out analysis and forms charcoal serviceability standards curve, and charcoal applicability is calculated by charcoal serviceability standards curve
Value.
Method provided by the invention is fairly simple, and charcoal compares in effect of the different time sections to soil and crops
Significantly, the yield of crops can be effectively improved, analysis method is simple, and the applicability value of obtained charcoal is accurate, analysis week
Phase is short, saves the time.
Further, the amount that charcoal is applied in step S1 soil is thousand grams/acre of 3-5.
Further, the sodium bicarbonate solution is prepared by the following method：Take 5~7g sodium bicarbonate solid powder
End, put it into agitator, thermometer three-necked flask in, while add with the sodium acid carbonate mass ratio be 1:2
Water, it is 70~80 DEG C in temperature, rotating speed stirs under conditions of being 150~180 revs/min, is completely dissolved the sodium acid carbonate,
Obtain sodium bicarbonate solution.Sodium bicarbonate solution is chosen so that data analysis fluctuation is smaller, in analysis method, is easy to
Control, use are more convenient.
Further, the tool of supernatant 1, supernatant 2 and supernatant 3 step S2, is prepared in step S5 and step S7 respectively
