Each gutter is provided to contain a plurality of crop units and the guide is provided to guide the gutters in a first direction and to gradually increase the distance between adjacent gutters in said direction so that the number of crop units per square metre in the area substantially decreases. The area comprises first and second zones, and each gutter in the first zone contains crop units with a first intermediate distance and each gutter in the second zone contains crop units with a second intermediate distance. The first intermediate distance is considerably smaller than the second intermediate distance and the distance between gutters in the first zone at the position of a transition from the first zone to the second zone is considerably greater than the distance between gutters in the second zone. ## Claims ### Claim 1 A system for cultivating a crop, comprising: a guide for guiding a plurality of gutters in a predetermined area, wherein each gutter is provided to contain a plurality of crop units of the crop and wherein the guide is provided to guide the gutters in a first direction extending from a first edge to a second edge of the area, wherein the guide is further provided to gradually increase the distance between adjacent gutters in said first direction, such that the number of crop units per square metre in the area substantially decreases from the first edge to the second edge, wherein the area comprises a first zone adjacent to the first edge and a second zone adjacent to the second edge, and wherein each gutter in the first zone is provided to contain crop units with a first intermediate distance and wherein each gutter in the second zone is provided to contain crop units with a second intermediate distance, and wherein the first intermediate distance is considerably smaller than the second intermediate distance and wherein the distance between adjacent gutters in the first zone at the position of a transition from the first zone to the second zone is considerably greater than the distance between adjacent gutters in the second zone at the position of the transition. ### Claim 2 (depends on 1) The system for cultivating a crop as claimed in claim 1, wherein the ratio of the first intermediate distance and the second intermediate distance and the ratio of the distance between adjacent gutters in the second zone and in the first zone at the position of the transition is chosen such that the number of crop units per square metre remains substantially constant along the transition. ### Claim 3 (depends on 1) The system for cultivating a crop as claimed in claim 1, wherein the guide comprises a drive for moving the gutters in the first direction, and wherein the drive is provided to change the distance between adjacent gutters in said first direction. ### Claim 4 (depends on 3) The system for cultivating a crop as claimed in claim 3, wherein the drive is formed by a plurality of pull rods and wherein at least one covering of a pull rod system connected to a chain and a separate pull rod system are provided in order to fill the gap created in the field with crop units, such that the gutters are pulled into this gap. ### Claim 5 (depends on 1) The system for cultivating a crop as claimed in claim 1, further comprising a device for transplanting at least part of the crop units along said transition from the first zone to the second zone. ### Claim 6 (depends on 5) The system for cultivating a crop as claimed in claim 5, wherein the device is provided to transplant all crop units from gutters in the first zone to gutters in the second zone. ### Claim 7 (depends on 1) The system for cultivating a crop as claimed in claim 1, wherein each gutter comprises a plurality of means for containing a crop unit, this plurality of means having predetermined intermediate distances in the longitudinal direction of the gutter. ### Claim 8 (depends on 7) The system for cultivating a crop as claimed in claim 7, wherein the gutters are tubular or U-shaped in cross-section with a lid, wherein the plurality of means are formed as openings in the cover, and wherein each opening is formed to contain a crop unit such that medium and roots of the crop unit are situated substantially under the cover while leaves of the crop unit are situated substantially above the cover. ### Claim 9 (depends on 1) The system for cultivating a crop as claimed in claim 1, wherein the gutters are placed in a draining manner and wherein the system comprises at the position of one end of the gutters a water dosing system and at the position of another end of the gutters a water collecting system, such that water flows through the gutters in a controlled manner during use of the system. ### Claim 10 (depends on 9) The system for cultivating a crop as claimed in claim 9, wherein the water collecting system is operatively connected to the water dosing system such that water can be recuperated. ### Claim 11 (depends on 9) The system for cultivating a crop as claimed in claim 9, wherein a plurality of water dosing systems and a plurality of water collecting systems are provided so that a different quantity of water and/or water with different properties can be supplied to various of said gutters. ### Claim 12 (depends on 1) The system for cultivating a crop as claimed in claim 1, wherein the system further comprises a raising zone with a further guide for guiding a plurality of raising gutters in a further area adjacent to the first edge, wherein each raising gutter is provided to contain a plurality of the crop units with a further intermediate distance which is considerably smaller than the first intermediate distance, wherein the guide is provided to gradually increase the distance between adjacent raising gutters in said first direction and wherein the distance between adjacent raising gutters at the position of a further transition from the raising zone to the first zone is considerably greater than the distance between adjacent gutters at the position of the further transition, such that the number of crop units per square metre remains substantially constant along the further transition. ### Claim 13 A method for cultivating a crop, comprising: planting crop units of the crop in a plurality of gutters at a position of a first edge of a predetermined area; guiding the plurality of gutters in a first direction which extends from the first edge to a second edge of the predetermined area, wherein the distance between adjacent gutters gradually increases during the guiding such that the number of crop units per square metre decreases from the first edge to the second edge; harvesting the crop units at the position of the second edge; wherein the method further comprises: transplanting at least part of the crop units along a transition from a first zone of the area adjacent to the first edge to a second zone of the area adjacent to the second edge, such that each gutter in the first zone is provided to contain crop units with a first intermediate distance and each gutter in the second zone is provided to contain crop units with a second intermediate distance, wherein the first intermediate distance is considerably smaller than the second intermediate distance and wherein the distance between adjacent gutters in the first zone at the position of the transition is considerably greater than the distance between adjacent gutters in the second zone at the position of the transition. ### Claim 14 (depends on 13) The method for cultivating a crop as claimed in claim 13, further comprising: advancing at least part of the plurality of gutters in the first direction by means of a drive.
