My god.(7) by the bamboo charcoal kiln discharge obtained after calcining in step (6) and be broken into the diameter bamboo charcoal powder less than 3mm, by bamboo charcoal powder with
Soil mixes with mass ratio 1:15.Advantages of the present invention: with pure natural bamboo wood as raw material, without any additive and lyotrope,
Prepared soil conditioner is a kind of Green Product corrosion-free, nontoxic, non-harmful, and can strengthen the suction of soil
Water, water conservation, fertilizer conservation performance, can change the pH value of soil, and high performance-price ratio is high simultaneously.
Detailed description of the invention
The detailed description of the invention of the present invention is described below.
The preparation and application of a kind of soil conditioner, comprises the following steps, and bamboo wood is placed on outdoor 5 to 7 days by (1)
After, then it is stacked at earth kiln.Using fuel (timber) to directly heat mode to heat earth kiln from kilneye, the heat of generation rises
After kiln crown, to kiln internal diffusion；(2) soil kiln temperature is controlled at 60 DEG C～100 DEG C, in burning kiln, be positioned at the portion of bottom simultaneously
Point bamboo wood, thus generate flue gas in earth kiln, by the way of sootiness, the bamboo wood put in earth kiln is carried out pre-dried 3 to
5 days, remove volatile material；(3) soil kiln temperature is controlled at 100 DEG C～150 DEG C, bamboo wood is dried process 5 to 7
My god；(4) soil kiln temperature is controlled at 150 DEG C～270 DEG C, bamboo wood is carried out pre-carbonization and processes 5 to 7 days；(5) by temperature in earth kiln
Degree controls at 270 DEG C～450 DEG C, bamboo wood carries out carbonization and processes 5 to 7 days；(6) soil kiln temperature is controlled at 450 DEG C～
1000 DEG C, bamboo wood is carried out calcination processing 5 to 7 days；With relief earth kiln natural cooling, kiln discharge when kilneye temperature is 50～60 DEG C
?；(7) by the bamboo charcoal kiln discharge obtained after calcining in step (6) and be broken into the diameter bamboo charcoal powder less than 3mm, by bamboo charcoal powder
Mix with mass ratio 1:15 with soil.
Preferably: above-mentioned bamboo wood is with 3 years above high mountain Phyllostachys pubescens Mazei ex H.de Lebaies of life as raw material, a length of 1m～1.5m thick bamboo tube.
In step (2), soil kiln temperature is controlled at 70 DEG C, bamboo wood is carried out pre-dried 5 days；In step (3), by temperature in earth kiln
Degree controls at 120 DEG C, and bamboo wood is dried process 6 days；In step (4), soil kiln temperature is controlled at 200 DEG C, to bamboo wood
Carry out pre-carbonization to process 5 days；In step (5), soil kiln temperature is controlled at 350 DEG C, bamboo wood is carried out carbonization and processes 5 days；Step
Suddenly, in (6), soil kiln temperature is controlled at 800 DEG C, bamboo wood is carried out calcination processing 6 days.
The following is the part that the bamboo charcoal soil conditioner of preparation shared by the present invention is carried out to detect and related conclusions:
1. bamboo charcoal particle diameter, the initial mass concentration of pesticide, adsorption column height, flow rate of liquid, solution ph are to bamboo Charcoal Adsorption acetyl
Bayer 71628 and dichlorvos all have a certain impact.When bamboo charcoal particle diameter be 0.3～0.245mm, at the beginning of orthene and dichlorvos
When beginning mass concentration is 0.3 g/L, pH value of solution=7, adsorbent packed height are 6 cm, flow rate of liquid is 8 mL/min, bamboo charcoal pair
The dynamic saturated adsorption capacity of orthene and dichlorvos is respectively 41mg/g and 30.6 mg/g.Visible, bamboo charcoal has in water
The absorption property of machine phosphorus insecticide is good.
2., when the mass ratio of bamboo charcoal Yu soil is 1:15, average moisture content when mixture absorbs water saturated in pure water is
33.5%, the average time keeping moisture when ambient temperature is 60 DEG C is 24.3 h.Add the chlorine that 50 ml concentration are 40 mg/L
Changing ammonium and potassium dihydrogen phosphate, after 4 drip washing, ammonium nitrogen and P elements cumulative leaching rate only have 10.4% and 12.7%.Can
Seeing, bamboo charcoal has potentiation to water suction, the water retention property of soil.
Learning the most after testing, bamboo charcoal is alkalescence, its pH value often between 7.7 ~ 10.2, the normal same carbonization temperature of pH value of bamboo charcoal
Having close being correlated with, along with carbonization temperature raises, in bamboo charcoal, acid volatile matter content is less, and pH value often can raise.It is contemplated that,
In acid ground, use bamboo charcoal, be conducive to the pH value of the soil improved and reduce the saturation of its aluminum.Test shows, at pH is
The tea garden soil of 4.3 is executed 0.5 kg m-2Bamboo charcoal, in the most continuous 2 years, the pH value of soil improves 0.5 ~ 1 unit.
Pot experiment shows, the effect of the bamboo charcoal pH value to improving chiltern and loamy texture soil is greater than clayey soil.
Equally, bamboo charcoal also has significantly impact to the degree of base saturation of soil.Soil can be caused to hand over after adding bamboo charcoal
Transsexual base cation substantially increases, and its value is often much larger than the increase of the base exchange capacity of soil, causes the most former of this phenomenon
Cause is that the ion in bamboo charcoal is most of not to exist under electrostatic force, and the state as soluble-salt exists, therefore,
Bamboo charcoal is not only soil conditioner, is also a kind of fertilizer.
To sum up, soil conditioner prepared by the present invention has the advantage that a, with pure natural bamboo wood as raw material, without any
Additive and lyotrope, be a kind of Green Product corrosion-free, nontoxic, non-harmful.B, the water suction of soil, guarantor can be strengthened
Water, fertilizer conservation performance；C, the pH value of soil can be changed；D, high performance-price ratio are high.
Above are only the detailed description of the invention of the present invention, but the design concept of the present invention is not limited thereto, all utilize this
Design carries out the change of unsubstantiality to the present invention, all should belong to the behavior invading scope.
