Abstract
The invention discloses a phenolic resin foam medium block for cuttage. A specific activating agent is added in a phenolic resin matrix and is physically foamed by a foaming agent to form a loose cross-linking structure; then the loose cross-linking structure is cured to form a microporous foam body with a certain strength under the action of a curing agent; and finally the foam body is cut into a medium block for cuttage. The medium block is provided with microporous holes and is light in weight, low in price and high in planting percentage during cuttage for planting seedlings; due to the blocky characteristic, the phenolic resin is extremely firm, cultured seedlings are especially suitable for long-distance transportation, and thus the possibility that the root system is damaged is reduced; the damage to the root system hardly occurs when the cultured seedlings cut by the medium block are transplanted; the root system is strong in vitality and stress resistance, so that the recovering stage after the plants are transferred into basins is greatly shortened; and the plants are grown to be consistent after the seedlings cut by the medium block are transferred into the basins or transplanted and the rate of the finished products is high.
Description
Technical field
The invention belongs to field of plant growing technology, relate to a kind of cuttage and use medium, be specifically related to a kind of cuttage and use the phenolic resin foam medium block.
Background technology
The plant cuttage used medium is very extensive, and habitual inorganic medium comprises vermiculite, perlite, rock wool, sand, slag and haydite etc., and organic medium then comprises peat, bark, wood chip, wood shavings, burnt chaff and rice husk etc.
Vermiculite unit weight is 0.07 to 0.12 gram/cubic centimetre, and the pH value is 7 to 9, and body is light and have higher cation exchange capacity, and strong especially preserve moisture and fertility ability is arranged; Need not sterilize during use, but not contain any nutrient, life-time service; Be prone to fragmentation, hole diminishes, ventilation and drainage performance variation; Perlite unit weight is 0.08 to 0.18 gram/cubic centimetre, and the pH value is 7 to 7.5, is prone to draining, and permeability is good, and physicochemical property are stable, cleans asepticly, is neutral reaction, but does not have nutritive ingredient; Rock wool unit weight is 0.07 gram/cubic centimetre, and total porosity is 96%, and the pH value is sterilized through hyperthermia than higher fully; Definite shape is arranged, indeformable in the cultivation process, have higher water holding capacity and lower moisture tension, the cultivation initial stage is a slight alkalinity; But the shock-absorbing capacity of itself is low, and irrigation water is had relatively high expectations, if contain toxic substance in the irrigation water or cross secondary element; The capital damages, and can not degrade the occurring in nature rock wool, is prone to cause environmental pollution; Husky unit weight is bigger, can reach 1.5 to 1.8 gram/cubic centimetres, and husky water holding capacity and cation exchange capacity are less, and water displacement is good, and permeability is strong, low price, and wide material sources, but do not contain organic nutrient, and the preserve moisture and fertility ability, density is big, changes medium and takes a lot of work; The slag wide material sources, permeability is good, and unit weight 0.7 to 0.8 gram/cubic centimetre is difficult for being used as separately medium, is alkalescence; Haydite inside is cellular hole structure, and unit weight is 0.3 to 0.5 gram/cubic centimetre, can be not fine and close; Have suitable water holding capacity and cation exchange capacity, haydite can improve air permeability in potted plant medium, no pathogenic bacterium; No insect pest, no weed seed can not decompose; Can life-time service, can keep afloat.
Peat unit weight is little, is 0.2 to 0.3 gram/cubic centimetre, and porosity is up to 77% to 84%, light weight; The quality favorable and stable, slant acidity, the preserve moisture and fertility performance is good, and organic content is high; Water holding capacity and cation exchange capacity are high, have good permeability, can resist fast to decompose; But use the difficult suction of peat first and when its complete drying, be prone to form lump, moisture also is difficult for suction, and quality gently is not suitable for planting higher large-scale flowers and trees; The appearance matter of bark is compared with the peat composed of rotten mosses near the peat composed of rotten mosses, and cation exchange capacity and water holding capacity are lower, but carbon nitrogen ratio is higher; Be a kind of reasonable dielectric material, have good physical properties, can partly replace peat as cultivation medium; But the decomposition rate of fresh bark is fast, and bark should notice that wherein muriate should not surpass 0.25% in use; The content of manganese must not be higher than 200 mg/kg, surpasses this standard, and medium is not easy to do; Wood chip and bark have similar character, but are easier to decompose deposition, and too densification to be difficult for dried flower approximate with wood chip on forming, just individual big, air permeability is good, carbon nitrogen ratio is high, measure and cation exchange capacity lower; Burnt chaff unit weight is 0.24 gram/cubic centimetre, and aeration porosity can reach the pH value and be slight alkalinity, but after watering several times, can show neutral, and it is relatively poor to absorb the nutrient ability; Rice husk has good draining and air permeability, does not also influence the original pH value of blending agent, soluble salt or effectively nutrition, and can resist decomposition; Therefore higher use value is arranged, but how germ to carry out boiling before use usually, with kill pathogenic bacteria; When steam disinfection, can discharge the manganese of some amount, might make dunsiekte, carbon nitrogen ratio is high; To add about nitrogenous fertilizer of about 1.0% after the sterilization, to compensate the shortage of the nitrogen that high C/N ratio caused.
Select suitable cultivation medium very important, clean, stable structure, enough air permeability and draining superperformance are arranged, the proper physical proterties can be provided for the growing environment in root district.Nowadays most of growth mediums are to be main blending agent with peat, add perlite, vermiculite, haydite, wood chip, bark or husky one or more central materials usually and mix, and these blending agents are applicable to most potted plants.Combining medium can be varied, but the basic demand in medium is prepared is consistent, and comprising: i.e. draining is good, can in the middle of twice irrigation, can keep the good humidity demand with the assurance plant simultaneously again.The solubility salt that contains on the one hand is relatively low, has enough ion-exchange capacities to keep on the other hand again and supplies with the required bioelement of plant-growth.Because pathogenic bacteria, grass seeds, toxic substance that peat soil contains comparatively speaking are few; Good physical behavior can be provided; Include good porosity and good water-holding power; And have good ion-exchange capacity and buffering ability, therefore most the employing with peat of business-like medium is main blending agent.
Use various cuttage media, rootage duration, surviving rate and the institute coefficient amount of taking root is not ideal enough, and because medium is not an integral body, and damage root system easily when long-distance transportation is grown seedlings and also damaged root system when transplanting easily.
Summary of the invention
In order to overcome the defective of existing various cuttage media, the invention provides a kind of medium block that is more suitable for cuttage, adopt phenolic resin foam to make.
This medium is as base material with resol; Under the effect that adds specific promoting agent; Physical blowing through whipping agent itself forms loose crosslinking structure; Under the solidifying agent effect, make it solidify to form the fine-celled foam body of certain intensity then, again foams are cut into medium block, use in order to cuttage.
Described phenolic resin foam PH is 5.5-6.5, EC≤0.3
This cuttage medium block profile can be Polygons, cylinder or round platform, and described Polygons can be the chamfered edge stage body, also can be square or rectangular parallelepiped.

The medium block that with the phenolic resin foam is base material is as cuttage, compares with seedling raising mannerses such as traditional turfy soil, perlites, and have following significant advantage: seedling rate is high, and energy-conservation saving of labor improves the greenhouse utilization ratio; This medium is cheap, and under the equal volume, its price has only 1/3rd of import turfy soil, big seedling cost; Be prone to loose comparing with the native ball that the import turfy soil is grown seedlings; The block characteristic of this medium is solid; Use growing seedlings of this medium to be particularly suitable for long distance and transport on the way, and be difficult for causing almost zero damage of root system when transplanting of growing seedlings of hindering the medium cuttage of root system, root system is energetic; Strong stress resistance makes that the seedling-slowing stage behind the basin shortens greatly on the plant; This medium is grown seedlings and has been solved fundamentally that bacterium fly (fungi mosquito) larva stings the food callus and the situation that causes cuttage survival rate to decline to a great extent; Basin or transplanting back plant strain growth neat and consistent on this medium cuttage seeding, the potted flower yield rate is high.
Embodiment
Below in conjunction with embodiment the present invention is done further detailed explanation, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Cuttage medium of the present invention is as base material with resol; Under the effect that adds specific promoting agent; Physical blowing through whipping agent itself forms loose crosslinking structure, under the solidifying agent effect, makes its fine-celled foam body that solidify to form certain intensity then, again foams is cut into 1 to 10 centimetre of thickness; Length and width are 1 to 5 centimetre medium block, use in order to cuttage.
The existing concrete application that this medium is described with cuttage poinsettia seedling:
1, in the last week of growing seedlings seedling cultivation greenhouse is weeded a garden, washes work such as ground, desinsection, sterilization up hill and dale.Simply, available calcium lime powder spreads ground, chlorinated lime or the spraying of other broad-spectrum germicide; Cave dish and other apparatus use common sterilizing agent sterilization, and blade is sterilized with 75% medical alcohol wiping, infect with the intrusion that prevents fungi, bacterium.In the greenhouse, hang subsequently and lure the yellow plate of worm, be ready to cuttage medium (specification: the high 3.5cm of the wide 2cm* of long 2cm*), water permeable.
2, should go cuttage after the fringe incision is dried again with inserting during cuttage, influence rooting rate to prevent to insert a large amount of losses of juice in the fringe body.Select the stalwartness big or small, that thickness is consistent to insert fringe, cutting length is 4 to 4.5 centimetres, and the cuttage degree of depth is inserted fringe for inserting 1 to 1.5 centimetre in medium.
3, cuttage temperature is controlled at 21～22 ℃ of nights, 25～28 ℃ of daytimes.
4, cuttage humidity: after the cuttage in 3 days; For preventing that inserting fringe causes the blade dehydration because of transpiration, humidity is controlled at 90～95%, and callus is completed into after the week; Humidity should be reduced to 70～80% gradually, every other day tackles the cuttage medium block and waters big flood one time.
5, illumination (after cuttage 5～10 days) before callus forms remains on 5000～8000Lux, strengthens gradually later on, after root system forms, begins to refine seedling about 15000～20000Lux.
6, medicament uses: promptly with 1000 times of liquid sprayings of 70% m-tetrachlorophthalodinitrile 2～3 times, till being sprayed onto the blade face and having water droplet to flow down, later per sterilant that once used different mechanism in 7～10 days is in turn sprayed and is prevented the generation of disease after the cuttage.
The slotting fringe female parent of this cuttage test should guarantee not have disease and pest; Fertilizer uses 200～300ppm20-10-20 water soluble composite fertilizer; Also answer every month 80ppm nitrocalcite of supplementation administration+40ppm sal epsom EC value to be controlled at 1.5～2.0; PH value is controlled at 5.5～6.5, and intensity of illumination is controlled at about 30000～50, and illumination at noon is crossed by force and should suitably be shaded.The principles such as " do between wet ", " do not do and do not irrigate " of watering and to follow.Basin soil overdrying is prone to make the nutrition fibrous root drying shrinkage of plant impaired, and is unfavorable to root growth; Basin soil is wet excessively, because of ponding in the basin, causes its nutrition fibrous root to rot, and is harmful to the growth of root system equally, and general 50% above basin soil surface is done (the soil table turns white) and just can be watered, and minority basin soil is done and should be noted timely moisturizing.PH value of one week survey and EC value.The too high or too low meeting of pH value causes nutritional deficiency, acid adjustment in time; The EC value is hanged down excessively and is answered application in time.At least surveyed twice pH value and EC value in one month.In order to control the excessive growth of inserting fringe, per 7～10 days use growth control agents (700～1000ppm alar-85+700～1000ppm choline dichloride).
This test is accomplished under same greenhouse state, and all cuttage 1000 strains poinsettia of the same size inserts fringe in every kind of medium.Can find out that from last table result in all slotting fringes, poinsettia seedling rootage duration is the fastest under the phenolic resin foam medium, surviving rate is the highest, and institute's coefficient amount of taking root is also maximum:
1, the cuttage root-taking time has shortened to 13 days by 20 to 25 days of the duration of growing seedlings of original traditional way;
2, surviving rate is up to 99.6%;
3, root quantity showed increased, root system is longlyer living.
Compare with seedling raising mannerses such as traditional turfy soil, perlites, have following significant advantage: seedling rate is high, and energy-conservation saving of labor improves the greenhouse utilization ratio; This medium is cheap, and under the equal volume, its price has only 1/3rd of import turfy soil, greatly reduces seedling cost; The native ball of growing seedlings with the import turfy soil is prone to loose comparing, and the block characteristic of this medium is extremely firm, uses growing seedlings of this medium to be particularly suitable for long distance and transports on the way, and be difficult for causing the injury of root system; Almost zero damage of root system when transplanting of growing seedlings of this medium cuttage, root system is energetic, and strong stress resistance makes that the seedling-slowing stage behind the basin shortens greatly on the plant; Having solved bacterium fly (fungi mosquito) larva on this medium is grown seedlings
stings the food callus and causes cuttage survival rate significantly to descend condition; Basin or transplanting back plant strain growth neat and consistent on this medium cuttage seeding, the potted flower yield rate is high.
Because this medium bulk itself, microvesicle hole, light-weight characteristics are very suitable for the multilayer cuttage simultaneously because its low density (itself is suspended in the water surface) makes that plantation water gardening sightseeing plant becomes possibility on the water surface.
Cuttage of the present invention is not limited to the application in the cuttage of poinsettia seedling with the phenolic resin foam medium block, is applicable to the cuttage or the soilless culture of other plant seedling too.
