Abstract
The invention relates to a culturing and seedling medium for cucurbits and vegetables. The culturing and seedling medium is prepared by uniformly mixing the following raw materials in percentage by weight: 10%-45% of urea resin foam particles, 10%-30% of straw-cow dung leavening and 15%-40% of wood fiber. A preparation method of the urea resin foam particles comprises the steps of regulating the pH of a 28% formaldehyde solution to be 5.8-6.4 by virtue of 20% sodium hydroxide, carrying out condensation polymerization on urea and the 28% formaldehyde solution for 1 hour to obtain a urea resin solution, mixing butyl naphthalene sodium sulfonate with phosphoric acid to prepare foaming liquid, adding the foaming liquid into the urea resin solution so as to obtain urea resin foam, and preparing the urea resin foam particles by virtue of foam particle production equipment. According to the culturing and seedling medium, the urea resin foam is of a particle shape, is large in particle size, strong in air permeability and is beneficial to the rooting and the germination of large-particle-size seeds; meanwhile, perlite and vermiculite are not used, so that dust harmful to human bodies is reduced by above 80%; by replacing grass carbon with the wood fiber and the straw-cow dung mixed leavening, the emission of solid waste of straws is reduced, and the excessive reliance on perlite and vermiculite is solved.
Description
Technical field:
The present invention relates to cultivation and seedling medium technical field, particularly a kind of melon dish cultivation and seedling medium.
Background technology:
Soilless culture (soilessculture) refer to without natural soil with matrix or only nursery time matrix, carry out the cultivating method of irrigating with nutritive medium after field planting, can Economization on land, because soilless culture can the good rhizospheric environment of artificial creation, effectively prevent soil from connecting and do disease and soil salt accumulates the physiological barrier caused, fully meet the needs of crop to envrionment conditionss such as mineral nutrition, moisture, gases, the basic material of cultivation again can recycle, therefore has water-saving, economizes the features such as fertilizer, saving of labor, high yield and high quality.
Live through the whole nation in 2010 on a large scale after snow disaster, industrial seedling rearing is accepted by many agriculture aspect knowledgeable people gradually, and this also greatly facilitates the research of the application aspect of seedling medium.More substrate material is used to have peat, rock wool, vermiculite, perlite, bagasse, mushroom slag, grit and haydite etc.Current rock wool and peat are most widely used general in the whole world, are the comparatively ideal cultivation matrixes of generally acknowledging in the world.But along with using in a large number year by year, its negative effect of bringing to society and ecotope also becomes clear day by day, on the one hand due to rock wool non-degradable, a large amount of use brings secondary pollution to environment; On the other hand, peat is non-renewable resource, and excessive exploitation has the danger of exhaustion; Therefore, to seek and the excellent Novel seedling raising matrix of excavating the be easy to get materials such as inexpensive, alternative peat, rock wool has become one of current researcher study hotspot.
Develop the organic substrates such as coconut fiber, bark, wood sawdust abroad, not only significantly can reduce cultivation cost, and decrease the pollution to environment.China starts late to matrix research, and " gather materials on the spot, research and development of suiting measures to local conditions " becomes common recognition, as strengthened the research of the reasonable employment after to charred rice husk on the south the Changjiang river; Slag is strengthened in North China, and coordinates the research that the material mixing such as the peat composed of rotten mosses, vermiculite, sawdust use; The research to the peat composed of rotten mosses, sawdust etc. is strengthened in northeast; And in Shandong, Jiangsu, Henan one band have studied and obtain larger popularization with seedling medium products such as perlite, vermiculite, the peats composed of rotten mosses with suiting measures to local conditions; The research etc. to sand culture technology is then strengthened in great Northwest.More domestic scientific research institutions have more or less carried out matrix development research at present, enter the practical stage, but cost is higher, consumption of natural resource is serious, and wherein replace perlite and vermiculite with urea formaldehyde resin foam particle, replace the peat composed of rotten mosses with xylon, production nursery or cultivation are that the research report of matrix body material is not seen.
Urea formaldehyde resin foam has the plurality of advantages such as quality is light, water absorbing and retaining properties good, manufacture abundant raw material, cheap, technique is simple, soilless culture substrate newer at present adopts urea formaldehyde resin foam plate, earthing earth, sand thereon, rich Nitrogen element, but lack phosphorus, potassium, organic matter and micro-.This matrix due to wherein lower floor be the comparatively high consumption of tabular to urea formaldehyde resin foam, not ideal enough, nutritive substance is positioned at upper strata in addition, and seedling is taken root on urea formaldehyde resin foam plate, and nutritive substance is not easy to arrive root, and effect is not ideal enough; Further, the rear bad process of urea formaldehyde resin foam plate, to imbed in soil decomposition rate or not ideal enough, becomes more reluctant rubbish.
The formula that domestic the most frequently used nursery and cultivation matrix use in addition is the peat composed of rotten mosses about 50%, vermiculite/perlite (or half-and-half) accounts for about 50%, this formula is most widely used general at home and abroad at present, is the generally acknowledged comparatively ideal nursery of melon dish or cultivation matrix.But along with using in a large number year by year, its negative effect of bringing to society and ecotope also becomes clear day by day.The peat composed of rotten mosses mainly originates in China northeast, and limiting by region and belong to Nonrenewable resources, is the sole support of wetland, along with constantly exploitation will inevitably resource exhaustion.And perlite and vermiculite are mineral products, need form through high-temperature calcination is expanded, not by soil degrading, a large amount of use brings secondary pollution and ecological damage etc. to environment; On the other hand, along with nursery and cultivation matrix are widely applied, perlite, vermiculite are as non-renewable resource, topography and geomorphology considerable damage is caused by excessive exploitation, landslide, also because long-distance transport causes unnecessary tail gas pollution and society's waste, only Shang Dao bio tech ltd in Shandong just needs perlite and vermiculite 10 ten thousand stere every year, life-time service, the danger that part is economized, autonomous region's resource has exhaustion; Therefore, seek and excavate the excellent Novel seedling raising matrix of the be easy to get materials such as inexpensive, alternative perlite, vermiculite and cultivation matrix has become one of current researcher study hotspot.
