Definitions

  • the invention relates to methods for growing plants in which the rate of flow of irrigation water through the environment of the plant roots is controlled.
  • a growth substrate in particular a mineral wool growth substrate.
  • It also relates to an apparatus for carrying out the method.
  • It is well known to cultivate plants in a natural or artificial growth substrate, in particular a mineral wool growth substrate, such as rock wool or glass wool.
  • Water and, if necessary, fertiliser and other additives are supplied to the growth--, substrate, generally by ' causing water, optionally containing fertiliser and other additives, to flow through the substrate. It is important that the plants receive an adequate supply of water, of oxygen and of other materials such as fertiliser which are carried by the water.
  • Water is one of the means by which oxygen is carried into the growth substrate (although oxygen does enter the growth substrate by other means, such as directly from the air) .
  • oxygen does enter the growth substrate by other means, such as directly from the air.
  • water is supplied from a dripper positioned above a mineral wool growth substrate, the drops falling onto the substrate are highly oxygen-rich. This oxygen is carried into the substrate and taken up by the roots of the plant. Similar considerations apply to other additives dissolved in the water, such as fertiliser.
  • a greater rate of flow of water into the substrate increases the rate of supply of additives carried by the water. It is advantageous to have adequate water flow for other reasons. Increased water flow leads to increased turbulence around the roots, which increases the rate of transfer of beneficial components such as water and fertiliser into the roots.
  • Flow of water also removes undesirable by-products released into the growth substrate by the plants.
  • the maximum flow rate is normally determined by the maximum flow rate of water through the growth substrate under gravity. If the rate of supply of water exceeds this through-flow rate then excess water simply overflows. It is possible to modify the growth substrate so as to obtain a higher maximum through-flow rate. However, this generally requires reduction in growth substrate density, in particular in the case of mineral wool . This in itself leads to an inferior water distribution through the substrate.
  • the water level at the top of the growth substrate is much lower than at the bottom of the growth substrate. The top can become too dry and the bottom can become over-saturated.
  • EP-A-300,536 and EP-A-409, 348 disclose active water flow systems .
  • EP-A-300,536 discloses a system in which water flow through the growth substrate is controlled by a capillary system. Water conduits extend into the growth substrate and connect with a water pump. This is set at a predetermined rate to pump water out of the substrate. The conduit system is substantially filled with water and the flow rate is determined essentially by the rate set for the water pump.
  • This publication discusses "suction pressure" but this is in the context of the force required to be exerted by the plant to remove water from the substrate.
  • EP-A-409, 438 relates to the same water pump system. Additionally it provides coupling members between the conduit system and the growth substrate. The intention of these is to prevent growth of plant roots into the conduit system. It is stated that an advantage of the coupling members is that they remain more moist than the surrounding growth substrate and prevent air entering the conduit system from the slab side.
  • WO95/31094 describes a drainage system for active and passive liquid drainage of growth substrates. A series of growth substrates are provided each having a "suction plug" coupled to a siphon hose which drains into a standpipe.
  • the water content of the mineral wool is kept constant by supplying water to the mineral wool growth substrate via watering pipes and removing it via drain pipes.
  • a common pipe system is used for water supply and drainage.
  • this system as in the systems of EP-A-300,536 and EP-A-409, 346 discussed above, there is a continuous connection between water in the growth substrate and water in the drainage system.
  • Another known system for growing plants is known as the n ⁇ trient film .technique (NFT) system. In- this system plants are grown in small propagation blocks or even in no substrate at all, the plants, and blocks if used, being contained in a plastic container, such as a plastic film container.
  • WO03/005808 describes a system which addresses all of these problems in effective manner. It describes a system comprising a liquid drawing and air-locking device integrated within a growth system and which is part of a conduit system which uses a cavity partly filled with -liquid and. partly filled -with air to induce controlled release of liquid from the substrate.

  • the suction device is said to be made of a porous material, including stone (especially volcanic stone) , ceramic, mineral wool or porous glass.
  • Organic polymer foam and organic polymer fibres are also disclosed as potential materials for the suction device.

  • the preferred suction device materials in this publication have certain disadvantages. In particular, after a period of use nutrients in the water irrigating the system tend to precipitate at the surface of a stone or ceramic suction device. Given the small pore size of the suction device, this can result in clogging of the suction device.
