Definitions

  • the invention relates to a method for the culti ⁇ vation of plants.
  • the invention relates in particular to a method for the cultivation of plants wherein an organic material is used as substrate.
  • potting compost In horticulture, potting compost or rockwool is used as substrate.
  • potting compost is a substrate which has already been known for a long time, there are a number of disadvantages associated with potting compost.
  • stringent quality require ⁇ ments are imposed on potting compost.
  • potting compost must, for example, be substantially free from germs and seeds. Because potting compost is produced and transported on a large scale, potting compost regularly comes into contact with the at ⁇ mosphere. The seeds and germs floating around in the atmosphere can contaminate the potting compost. The consequence of this is that when potting compost is used in the cultivation of plants all sorts of undesired plant growth also occurs, for example the growth of weeds.
  • the invention provides a solution to these problems.
  • the invention therefore relates to a method for the cultivation of plants, wherein a substrate of cellulose which has a pF value of less than -0.05 cm" 1 is used.
  • a pF value is understood to have the following meaning.
  • a so-called pF curve is determined. This determination involves measuring the % by vol. water or the % by vol. air in the substrate as a function of the so-called pressure head.
  • Tray B is then lowered by, for example, 2 cm.
  • the pressure head is therefore 2 cm.
  • the equilibrium between tray A and tray B is then allowed to establish itself again and the % by vol. water in the sample is then determined at this pressure head. If it is desired to determine different % by vol. water in the sample as a function of the pressure head, the measurement ac- cording to the method described above can be carried out at the desired pressure heads. When the different % by vol. water are plotted against the pressure head, a so-called pF curve is obtained.
  • the pF value is thus the coefficient of the ex ⁇ ponential pF curve, that is to say a constant value.
  • a substrate wherein the substrate has a pF value of less than -0.04 cm '1 is preferably used.
  • the method according to the invention is suitable for the cultivation of various varieties of plants, the method according to the invention is pre ⁇ ferably used for the cultivation of seedlings, more preferentially seedlings of Perilla, Eruca, Raphanus and Brassica varieties.
  • the method according to the invention is used for the cultivation of Perilla arguta (Shiso purple), Perilla ocium frutescens (Shiso green), Brassica sinapis alba (mustard cress), Eruca vesicaria Spp sativa (rocket), Raphanus satival L ongipinatus (Daikon cress), Brassica juncea, Brassica lepidum (garden cress), sorrel, bio-cress, Basilicum (dark Opal) and Crypto- taenia japonica.
  • the method according to the invention can also be used for the cultivation of vegetable plants for culti ⁇ vation under glass.
  • This cultivation is carried out using so-called speedlings in trays.
  • This method of cultivation comprises filling squared racks, which are provided with rectangular cavities, with the substrate according to the invention, after which seeds are sown in the substrate. After the plants have reached a specific height, the substrate and the plants as a whole can be removed from the rectangular cavities with the aid of a pin, which is pressed against the under ⁇ side of the cavities.
  • the method according to the invention can also be used, for example: for cultivation of vegetable plants in the open ground, for example for raising in so-called “paper pots", for cultivation of flowering plants under glass, for example carnations, chrysanthemums and cuttings thereof, - for the cultivation of bedding and ornamental plants and other flowering plants for cultivation in the open air, as a propagating medium for tree nursery plants, as a growth medium for the cultivation of forced bulbous plants, for example for the cultivation of tulips and narcissi, and as a growth medium for the cultivation of herbs, for example parsley, dill, basil, and edible mushrooms, for example shitake, cultivated mushrooms and oyster mushrooms.
  • the invention also provides a method for making a substrate of cellulose for the cultivation of plants, wherein: a) cellulose is dispersed in an aqueous medium to produce a pumpable slurry, b) the slurry obtained in step a) is fed to one or more containers which are intended for the culti ⁇ vation of plants, c) all or part of the liquid is removed from the slurry contained in the containers mentioned in step b), with the formation of a substrate base in the bottom of the containers. It will be clear that not too much cellulose is dispersed in the aqueous medium, because the slurry would then become so thick that pumping thereof is virtually impossible.
  • step a) preferably 20-40 kg cellulose per 1000 1 aqueous medium, and in particular 15 to 30 kg cellulose per 1000 1 aqueous medium, are used.
  • the stirring speed used when dispersing the cellulose in the aqueous medium is such that the cellulose fibres do not break, tear or undergo another process which results in a change in the dimensions of the fibres.
  • the containers which are filled with the substrate can have all sorts of dimensions.
  • the containers can be circular, rectangular or square.
  • the containers can be combined with one another in racks, for example so- called trays, or can be individual containers.
  • the material from which the containers are made is not of essential importance.
  • the containers must, however, be such that they are permeable to the fluid, that is to say that the containers are provided with openings through which essentially only the fluid and not the substrate is able to run off or that the material from which the containers are made is permeable to the fluid. Examples of a material of this type are card ⁇ board or paper.
  • the substrate takes up about 10-50 % by vol. of the container or containers after complete or partial removal of the fluid and after the moist substrate has settled out.
  • this granulated cellulose is mixed with a suitable nutrient solution to a slurry with which the containers are filled by hand to a level corresponding to 80 to 100 % of the height of the container. It appeared that a substrate thus obtained does hardly or not settle. It will further be clear that when the substrate after complete or partial removal of the fluid and after settling of the substrate occupies only a part of the volume of the containers), a further quantity cellulose containing slurry may be transferred to the containers) to fill the container(s) completely or at least mainly com ⁇ pletely.
  • the granules comprising the granulated cellulose have a size of from 1 mm to 2 cm, preferably of from 2 mm to 1.5 cm and in particular of from 5 mm to 1 cm.
  • a substrate base may also be prepared from the granulated cellulose in an other way. First a slurry comprising the cellulose is prepared which contains an excess of water. The slurry is then pumped to a dis- charge device while the excess of water is removed from the slurry.
  • granules are prepared from this slurry, e.g. by rubbing or turning apart the cellulose particles contained by the slurry.
  • the granules thus obtained do, however, contain a particu- lar amount of water.
  • the container(s) are filled with the granules consisting of cellulose followed by moistening the granules. Any excess of water is then removed from the container by passing the water through the holes of the container. In this way a substrate is obtained having a relatively flat surface on which seeds are easily sown.
  • a cellulose is used which meets certain requirements and norms. This is particularly important when a substrate is made from the cellulose on which edible plants are cultivated. It will be clear that the cellulose must certainly not contain any substances which are harmful to the health of humans or animals and which, for example, can be absorbed by the plants. It is also undesirable that the cellulose contains substances which are soluble, emulsifiable or dispersible in the aqueous medium. According to the invention, therefore, a cellulose is used with which the quantity of material which can be extracted from the cellulose is preferably less than 0.2 % and in particular less than 0.1 %. The quantity of extractable material can be determined, for example, by the CPGA G.13 method or the SCAN-C 7:62 method.
  • a cellulose is used wherein the apparent density of the cellulose is between 450 and 500 kg/m 3 .
  • the cellulose is preferably not particularly strong, because a high strength makes dispersion of the cellulose in the aqueous medium more difficult.
  • a cellulose is preferably used which has a bursting index which is lower than 1 kPam 2 g.
  • the bursting index is a measure for the hydrostatic pressure which is needed to cause the cellulose to fall apart in a specific apparatus and under suitable conditions.
  • the bursting index is pre- ferably determined using the SCAN standard method.
  • a cellulose which has a pH of about 7.
  • a cellulose is used wherein the pH of the cellulose is between 6.5 and 7.5.
  • a nutrient solution can then be used which has a pH which is optimum for a specific plant.
  • a nutrient solution is preferably used which has a pH of about 4.5 to 6.5, in particular of 5.5.
  • a cellulose is preferably used wherein the fibres of the cellulose are not too large and not too small. If a cellulose with small fibres is used, when completely or partially removing the aqueous medium a large number of small fibres will also be entrained when the aqueous medium flows out via openings in the container. In such a case, a large quantity of the slurry would have to be fed to the containers in order to obtain a substrate base of the desired thickness.
  • Another disadvantage of fibres which are too small is that the density of the substrate then becomes too high. As a consequence, too little oxygen is able to penetrate into the substrate, which leads to a moderate growth of the roots.
  • a substrate base can be obtained in which the plants do not root well. The consequence of this is that the roots have less hold, as a result of which it is then frequently difficult or even impossible when harvesting the plants to remove the substrate and the plants growing thereon from the container as a whole.
  • a cor ⁇ rect fibre size and fibre size distribution are there- fore extremely important. According to the invention, therefore, a cellulose is used wherein the cellulose has more than 60 % fibres of more than 30 mesh and less than 20 % fibres of more than 200 mesh.
  • a cellulose is prefer ⁇ ably used wherein the specific volume of the cellulose in the dry state is between 15 and 25 dm 3 /kg.
  • the substrate according to the invention can also be used as a packing material for, for example, amaryl- lis plants.
  • the substrate can be saturated with a nutrient solution and then dried, the substrate being provided with nutrients which are needed for the growth of the plant. Said substrate can then be pressed into a desired shape. Later on the substrate pressed into a specific shape can be used for the cultivation of plants by moistening said nutrient-containing substrate with water and applying the seeds thereon.
  • a substrate of this type is very suitable for the cultivation of all sorts of plants by the amateur gardener.
  • a nutrient-containing substrate of this type can also be produced and transported on a large scale, as is customary with potting compost and rockwool.
  • During storage of the cellulose it may be conta ⁇ minated by micro-organisms such as bacteria and/or fungi which caused infection of the cellulose. These contaminations may occur when the cellulose comes in contact with the atmosphere and when during the pre- paration of the substrate the latter comes in contact with the nutrient solution.
  • the result is that undesired growth of bacteria and/or fungi may occur by which the ultimately grown plants are also contaminated with these bacteria and/or fungi. It is furthermore possible that the growth of the plants is adversely influenced by these bacteria and/or fungi.
  • lactic acid bacteria examples include Streptococcus clemoris, Streptococcus lactis, Streptococcus thermophilus, Lactobacillus bulgaricus and some subspecies of the genus Pseudomonas.
  • the slurry thus obtained is fed to racks of containers which are about 8 cm high. After the con ⁇ tainers have been almost completely filled with the slurry, the fluid is allowed to run off. Containers which are provided with an approximately 3 cm deep substrate base are thus obtained.
