Abstract
A medium technique for soilless culture features use of square rock wool blocks with a certain thickness. Said rock wool block is made up of rock ore through such technological steps as mixing it with limestone and cork, smelting in a high-frequency furnace, naturally flowing into a pottery pot, dropping molten liquid at 200 deg.C from hole at bottom of the pottery pot to centrifugal flywheel, centrifugal formation of rock wool, immersing the rock wool in solution of phenol or naphthylamino acid binder and using roll pressure with wood rod. Its advantages include high porosity, high water preservation, continuous culture, high elasticity and stable quality.
Description
The present invention relates to the soilless culture media technology, be applied to the sowing of class plants such as leaf vegetables, fruit and vegetable is cultivated.
Chinese patent application number is 98215501.8 and is called " a kind of device of planting flowers and plants " a kind of soilless culture medium that is foamed burnt stone is provided.Because foamed burnt stone is graininess, diameter is bigger, and the seed that spreads out during sowing moves to below the bottom water bit line along the space between foamed burnt stone, causes anoxic or soaks phenomenons such as rotten.Chinese patent application number is 88108546.4 to disclose a kind of being entitled as " pure asbestos composite ".It adopts basalt or diabase is raw material, adds lime stone, at high temperature obtains molten mass, after centrifugal the getting rid of of high speed rotating is drawn into pure rock wool.Its deficiency is that performance of keeping humidity is poor, is not suitable for the soilless culture medium.
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of performance of keeping humidity good medium product for soilless culture and the production method thereof that is applicable to the sowing cultivation.
Purpose of the present invention can reach by following measure: adopting basalt or diabase is raw material, adds limestone, and oozes with cork make molten mass in coreless induction furnace behind high temperature.Molten mass flows out in the buckpot naturally by the outage of coreless induction furnace side bottom.Buckpot is positioned at the below of coreless induction furnace side, and its bottom has an equally spaced pin hole, and the fused solution that flows out in the pin hole becomes wire to drop on the centrifugal flywheel of high speed rotating down continuously; Centrifugal flywheel rotating speed is not less than per minute 2000 to be changeed; The distance length that falls is cooled to 200 ℃ with the fused solution end temperature by air and is as the criterion.Behind centrifugal flywheel pull, form rock wool.After a certain amount of rock wool process phenol or naphthalene propylhomoserin binder solution soak is that available pin is rolled into the rectangular block with certain thickness and specification.
The present invention compares with prior art has following advantage:
1, the voidage height has excellent air permeability, is beneficial to plant growing;
2, since after adhesive soaks rolling forming, the rock wool body is not removed on it last one and is made remaining root system and destroy, so can plough continuously
Do;
3, elastic performance is good, not the deformation that produces irrecoverable original state because of common external force effect: training matter stay in grade, and pH value is moderate;
4, the pouring fertilising easily; The results post processing is easy;
5, do not have spreading of continuous cropping germ;
6, light weight is beneficial to the combination vertical cultivation;
7, low cost of manufacture.
In the enforcement, can select pyrophillite (emerald green stone) for use is raw material, adds limestone and cork (being wood chip), and by 60%, 20%, 20% the weight ratio coreless induction furnace of packing into, 1000 ℃ of right left sides can become molten mass to the three respectively.Compare with other ore, adopt pyrophillite (emerald green stone) to have the lower advantage of fusing point, can play the effect of saving the energy.The fused solution whereabouts distance that pin hole flows out at the bottom of the buckpot is approximately 1.5 meters, and the fused solution of falling on the centrifugal flywheel is cooled to about 2002.Can adopt phenol or naphthalene propylhomoserin to make adhesive separately and also both can be mixed use by arbitrary proportion.The mineral wool block specification of pin rolling forming can be with reference to selecting 5 centimeters of thickness for use, and length is 2 meters, and wide is 1.1 meters.
Claims (3)
1, a kind of medium product for soilless culture is characterized in that mineral wool block.
2, a kind of production method of medium product for soilless culture, adopting the rock ore deposit is raw material, add limestone, melt after centrifugal the making of centrifugal flywheel of high speed rotating with high temperature furnace, it is characterized in that in coreless induction furnace, infiltrating cork, molten mass spontaneous current after the fusing is to buckpot, and the temperature that drops on the centrifugal flywheel under the fused solution that flows out in the pin hole is about 200 ℃: make with the pin roll extrusion after rock wool that centrifugal flywheel pull forms is soaked through phenol or naphthalene propylhomoserin binder solution.
3, the production method of a kind of medium product for soilless culture according to claim 2 is characterized in that the raw material of selecting for use is pyrophillite (an emerald green stone), and infiltrates a certain amount of cork that the weight ratio of comparing the three with limestone is 60%: 20%: 20%.
