Abstract
The invention relates to a tobacco stem charcoal soil conditioner of acidic tobacco planting soil, and a processing method thereof. The chitosan thin film layer of the conditioner is wrapped outside a core layer, and the wrapping thickness of the chitosan thin film layer is 0.6-0.8mm; and the core layer is mainly composed of tobacco stem charcoal, calcium nitrate, magnesium nitrate, zinc oxide, borax and phosphate dissolving bacteria. The processing method of the conditioner mainly comprises the following steps: preparing tobacco stem charcoal from waste tobacco stems; crushing the tobacco stem charcoal; uniformly mixing all components of the core layer; sprinkling the phosphate dissolving bacteria; sprinkling a binder, and granulating; and dressing by using chitosan. In the invention, the tobacco stem charcoal has extremely strong water absorption and water retention abilities, an extremely high specific surface area and a loose physical structure, can effectively improve the content of organic carbon in soil, improves the soil nitrogen retention ability and potassium supply ability, improves the nutrients needed by the growth of tobacco, increases the mineralization release of effective phosphorus in soil, and can effectively improve the southern acidic tobacco planting soil.
Description
Technical field
The invention belongs to soil improvement agent technical field, relate to a kind of charcoal type soil improvement agent and working method thereof of acid tobacco-growing soil, be specially adapted to the improvement of acid tobacco-growing soil.
Background technology
Charcoal be agricultural crop straw, xyloid material, fowl and animal excrement or other organic materialss under low-oxygen environment, the class obtained through high temperature (300 DEG C-700 DEG C) pyrolysis has that specific surface area is large, hole is many, the height aromatize carbon rich material matter of absorption and the feature such as stability is strong.In recent years, charcoal causes extensive concern as the application of a kind of functional materials in the many research fields of agricultural, environment and the energy, and it presents considerable potentiality in soil tilth improvement, fertility lifting, reduction of greenhouse gas discharge and pollution amelioration etc.
Since the middle and later periods nineties 20th century, charcoal is increasing as the research of soil improvement agent and solid carbon agent, large quantity research shows that charcoal can significantly improve soil organic carbon after imposing on soil, be beneficial to the formation of soil agreegate and reduce the soil weight, improve acid soil pH, improve fertilizer nutrient utilization, strengthen guarantor's accumulation of energy power of soil available N and P potassium nutrition.And having good interaction due to charcoal and nitrogenous fertilizer, major part test proves that charcoal can promote seed germination, plant-growth improve crop yield and quality.
Yunnan Province cultivation cigarette is with a long history, and quality of tobacco has long enjoyed a good reputation, and is one of the whole nation and even foremost tobacco leaf main producing region, the world.But Crop Diseases in Yunnan pattern of farming development imbalances in recent years, in addition long-term unreasonable fertilising makes the field edatope of much planting tobacco run down, fertility declines, nutrient supply is unbalanced, harden serious, unit weight continues to increase, and cause cigarette strain retarded growth, larger fluctuation appears in quality of tobacco.
At present, charcoal applied research has carried out some research in wheat, corn, paddy rice and Soybean and Other Crops, but research on tobacco is also fewer, also not for the charcoal type soil improvement agent of typical cigarette district, south acid soil.To charcoal physico-chemical property quality standard, the preparation method of suitable tobacco, to rational formula, the amount of application of charcoal type soil improvement agent, and to the improved effect of soil and promote that the investigation and application of the aspects such as tobacco growth lacks the research of long-term field.
Summary of the invention
The present invention is directed in prior art the means lacking permanently effective stable lifting vega soil quality, lack product charcoal technology be applied in the improvement of tobacco planting field, particularly lack the situation of discarded cigarette stalk processing cigarette stalk charcoal soil improvement agent technology, a kind of cigarette stalk charcoal soil improvement agent and working method thereof of acid tobacco-growing soil are provided.
Technical scheme of the present invention is: a kind of cigarette stalk charcoal soil improvement agent of acid tobacco-growing soil and working method thereof, the cigarette stalk charcoal soil improvement agent of acid tobacco-growing soil mainly includes sandwich layer and chitosan film layer composition, chitosan film layer is wrapped in outside sandwich layer, and the Jacket thickness of chitosan film layer is 0.6mm-0.8mm; Calculate by weight, sandwich layer is made up of following ingredients, cigarette stalk charcoal 900-1000 part, nitrocalcite 50-60 part, magnesium nitrate 8-12 part, zinc oxide 8-12 part, borax 25-35 part.
The cigarette stalk charcoal soil improvement agent of acid tobacco-growing soil is obtained by following methods:
(1) cigarette stalk charcoal is prepared: the cigarette stalk staying field after being gathered in the crops by tobacco leaf dries and collects, the bar section that length is less than 10cm is chopped into stock cutter, put into charring furnace to carbonize, under anaerobic environment, control charing in-furnace temperature at 450 DEG C, cigarette stalk is carbonized gradually;
(2) obtained cigarette stalk charcoal is ground into the particle of particle diameter 2mm ± 0.5mm, for subsequent use;
(3) by each composition of sandwich layer, take and send into stirrer in right amount, stir; Spray phosphate solubilizing bacteria stoste thereon, in stoste, living bacteria count is no less than 25,000,000,000/mL, and the amount of sprinkling controls to be no less than 2.5 hundred million containing phosphate solubilizing bacteria living bacteria count in every gram of material, leaves standstill 6 hours;
(4) spray binding agent at material, the composition of binding agent is Xylo-Mucine, again stirs material, the wet stock mixed is sent into Squeezinggranulator granulation, naturally dries after granulation;
(5) adopt chitosan to carry out dressing to the particulate materials after oven dry, naturally dry after dressing, after dressing, the thickness of chitosan film is 0.6mm-0.8mm, is left standstill by material bagging and obtains finished product.
Cigarette stalk charcoal in above-mentioned working method after charing, all technical is:
