Abstract

A cruciferous seedling growing matrix is formed by uniformly mixing the following raw materials by weight percentage: 60-75% of urea-formaldehyde resin foam particles; 25-40% of vinasse powder particles. The preparation method of the vinasse powder particle comprises the following steps: adding VT-aerobic zymocyte in a vinasse, and the mass ratio between the VT-aerobic zymocyte and the vinasse is 1:2000; using pilling fermentation for 7-10 days; drying and smashing the material so as to obtain the vinasse powder particles. The urea-formaldehyde resin foam is in a particle shape; besides the self apertures of the urea-formaldehyde resin foam, mass apertures are formed between the urea-formaldehyde resin foam particles, thus ensuring water retaining, ventilation, rooting, and germination, and reducing urea-formaldehyde resin foam application amount, so the vinasse powder particles can be uniformly mixed; the vinasse powder particle can replace peat so as to reduce vinasse solid waste discharge, so the peat cannot be overly relied on, thus realizing sustainable development.

Description

Famous and precious trees seedling medium

Technical field:

The present invention relates to seedling medium technical field, particularly the famous and precious trees seedling medium of one.

Background technology:

Soilless culture (soilessculture) refer to without natural soil with matrix or only nursery time matrix, carry out the cultivation method of irrigating with nutrient solution 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 disorder caused, fully meet the needs of crop to environmental conditions such as mineral nutrition, moisture, gases, the stock of cultivation can recycle again, 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, factorial seedling growth is accepted by many agriculture aspect knowledgeable people gradually, and this also greatly facilitates the research of the application aspect of seedling medium.More host 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 cocoanut 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 the research coordinating the materials such as the peat composed of rotten mosses, vermiculite, sawdust used in combination; 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 developmental 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 xylem fibre, 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, nutriment is positioned at upper strata in addition, and seedling is taken root on urea formaldehyde resin foam plate, and nutriment 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.

In cultivation matrix conventional in addition large mainly with the peat composed of rotten mosses as primary raw material, and the peat composed of rotten mosses mainly originates in China northeast, belong to non-renewable resources by region restriction, along with continuous exploitation will inevitably resource exhaustion, find a kind of novel matrix and replace non-renewable resources to be very necessary.

Vinasse are remaining residues after the wine brewing such as rice, wheat, jowar, China is wine brewing big country, containing a large amount of dry matter, fiber, albumen and calcium, phosphorus in vinasse (white wine), can as the desirable substitute of the peat composed of rotten mosses, and because vinasse itself have passed through fermentation, zymophyte injected volume and shortening fermentation time in matrix production process can be reduced, and effectively can shorten fermentation time, be applicable to producing seedling medium fast.

Summary of the invention:

Given this, be necessary to design a kind of famous and precious trees seedling medium not containing the peat composed of rotten mosses, urea formaldehyde resin foam plate.

A kind of famous and precious trees seedling medium, is made up of the raw material Homogeneous phase mixing of following percentage by weight:

Urea formaldehyde resin foam particle 60 ~ 75%, vinasse powder 25 ~ 40%;

Described urea formaldehyde resin foam particle preparation method: by the formalin of 28% with 20% sodium hydroxide regulate pH value 5.8 ~ 6.4, formalin polycondensation reaction at 90 DEG C of urea and 28% is obtained urea-formaldehyde resin solution in 1 hour, by sodium butylnaphthalenesulfonate and phosphoric acid mixed configuration expanding foam solution, stir after expanding foam solution produces a large amount of foam and join urea-formaldehyde resin solution continuation stirring, obtain urea formaldehyde resin foam thing, obtain urea formaldehyde resin foam particle finally by foam beads production equipment, the particle diameter of urea formaldehyde resin foam particle is greater than 6mm and is less than 10mm;

The preparation method of described vinasse powder: add VT-aerobic fermentation bacterium in vinasse, the mass ratio of VT-aerobic fermentation bacterium and vinasse is 1:2000, and adopt raft fermentation 7 ~ 10 days, drying and crushing afterwards, obtains vinasse powder.

Urea formaldehyde resin foam of the present invention is granular, except the hole of urea formaldehyde resin foam itself, there is a large amount of hole between urea formaldehyde resin foam particle, just with water conservation, breathe freely, take root, teethe, reduce the usage amount of urea formaldehyde resin foam and convenient and vinasse powder Homogeneous phase mixing simultaneously; The discharge using vinasse powder to replace the peat composed of rotten mosses not only to decrease vinasse solid waste solves depending on unduly the peat composed of rotten mosses simultaneously, makes sustainable development become possibility, and effectively can shorten fermentation time, is applicable to producing seedling medium fast.
