Abstract
The invention relates to a nutrition sustained-release type plant culture medium prepared from straw raw material biogas residues and a processing method thereof. The biogas residues generated in biogas engineering taking straw as a main raw material are efficiently recycled, the raw material source of the plant culture medium is broadened, and the production cost of the plant culture medium is reduced; the biogas residues subjected to anaerobic fermentation are rich in various nutritional components, and can effectively promote plant growth and improve physicochemical properties of soil; meanwhile, the culture medium can be processed into various solid shapes and sizes according to the requirement to facilitate transportation and use. The culture medium consists of the following components: the straw biogas residues, sustained-release control substances, wheat bran, soybean cake power, light calcium carbonate, a trace amount of complex enzyme, an additive containing nitrogen, phosphorus and potassium, and plant seeds. A preparation method comprises the following steps of: drying the straw raw material biogas residues until the water content is lower than 18 percent, grinding, mixing the raw materials in a ratio, adding water, uniformly stirring, pouring into a mold, pre-embedding the plant seeds, appropriately extruding, and forming.
Description
Technical field
What present technique related to a kind of natural pond slag utilizes method again, is specifically related to a kind of nutrition slow-release type plant culture and working method thereof based on stalk natural pond slag.
Background technology
Plant culture claims " cultivation is gathered materials " or " slow-release nutrient soil " again, its principal feature is: directly utilize soil, perhaps process the matrix environment of a suitable plant-growth by manual type, the nutritive ingredient that plant-growth is required is placed wherein in advance, pre-buried as requested again plant or plant seed.Plant culture is all very convenient in transportation and use, and can greatly improve the survival rate of plant, so the wide range of its application.Composition as the disclosed biological multielement slow-release nutrient soil of CN1422829A is: contain organic and bioactive soil 50-90%, Semen Maydis powder 5-10%, rice bran 1-3%, wheat bran 0.5-3%, straw 1-10%, animal excrement 1-10%, oil meal 0-0.5%, the additive of micro-complex element and nitrogenous phosphorus potassium.At present common on the market plant culture and above-mentioned composition are similar, mainly are made up of five parts: inorganic nutrients thing, carbon source, VITAMIN, organic annexation, growth regulatory substance also will add other component simultaneously according to the actual requirements.But because part material cost higher (as micro-complex element), the processing of plant culture is subjected to certain limitation, and then has influenced its applying in every field.
On the other hand, China's stalk marsh gas development at present is very rapid, its final natural pond slag that produces is good organic fertilizer matrix, detect proof: organic substance is in anaerobic fermentation process, except carbon, hydrogen, elements such as oxygen are decomposition and inversion progressively, generate methane at last, outside the gases such as carbonic acid gas, all the other various nutrient elements substantially all are retained in the residuum after the fermentation, wherein a part of water-soluble substances is retained in the liquid of natural pond, another part does not dissolve or difficult decompose organic, inorganic solid substance then is retained in the slag of natural pond, has also adsorbed a large amount of solubility available nutrient on the surface of natural pond slag.So the natural pond slag contains more comprehensive micro-complex element and abundant organic substance, the essential nutrient contents in the slag of natural pond has: 30%～50% organic matter, 10%～20% humic acid, 0.8%～2.0% full nitrogen (N), 0.4%～1.2% full phosphorus (P), 0.6%～2.0% full potassium (K).But investigation finds, at present the stalk natural pond slag that produces of the stalk marsh gas engineering of China except that a part by the direct returning to farmland utilization, the overwhelming majority is dropped.Although so stalk natural pond slag is rich in nutrient, its utilising efficiency is not high.
Summary of the invention
The object of the present invention is to provide a kind of nutrition slow-release type plant culture based on stalk natural pond slag, the present invention will be the biogas engineering natural pond slag draining of raw material with the stalk and dry to water ratio also pulverizing below 18%, become one of main raw material of making plant culture, greatly widen the starting material source of plant culture, reduced the production cost of plant culture.Realized simultaneously deeply having excavated the nutritive value and the economic worth of stalk natural pond slag to being that the biogas engineering of main raw material produces efficiently utilizing again of natural pond slag with the stalk.
Another object of the present invention is to provide the working method of described nutrition slow-release type plant culture based on stalk natural pond slag.
Purpose of the present invention is achieved through the following technical solutions:
A kind of nutrition slow-release type plant culture based on stalk natural pond slag is characterized in that this culture medium raw material is composed as follows, is weight part:
