US3869826A — Cultivation of plants in greenhouses

Claim 1

Independent Claim 193 words

A process for cultivating physiologically and morphologically valuable plants in greenhouses which comprises cultivating said plants in a greenhouse having openings extending to groundlevel in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of groundlevel atmospheric air into openings in one wall and out of openings in another wall, said plants being supported in said greenhouse at a height whereby at least the uppermost portion of the atmospheric air flow passes through the foliage of said plants, thereby providing in the greenhouse movement of air which is closely similar to the groundlevel atmospheric air in direction, strength and natural rhythm, whereby the plants cultivated in said greenhouse are closely similar in habit and growth to the same types of plants cultivated and grown in the open atmosphere and applying a herbicidal composition to said plants to test the effectiveness thereof, and making statistical evaluations of the herbicidal activity upon said plants by said composition to obtain toxicity results approximating the herbicidal activity of the same composition when similarly applied to the same plants growing in the open atmosphere.

Claim 2

Dependent Claim 193 words

A process for cultivating physiologically and morphologically valuable plants in greenhouses which comprises cultivating said plants in a greenhouse having openings extending to groundlevel in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of groundlevel atmospheric air into openings in one wall and out of openings in another wall, said plants being supported in said greenhouse at a height whereby at least the uppermost portion of the atmospheric air flow passes through the foliage of said plants, thereby providing in the greenhouse movement of air which is closely similar to the groundlevel atmospheric air in direction, strength and natural rhythm, whereby the plants cultivated in said greenhouse are closely similar in habit and growth to the same types of plants cultivated and grown in the open atmosphere and applying a herbicidal composition to said plants to test the effectiveness thereof, and making statistical evaluations of the herbicidal activity upon said plants by said composition to obtain toxicity results approximating the herbicidal activity of the same composition when similarly applied to the same plants growing in the open atmosphere.

Claim 3

Dependent Claim 149 words

A process for cultivating physiologically and morphologically valuable plants in greenhouses which comprises cultivating said plants in a greenhouse having openings in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of atmospheric air into openings in one wall and out of openings in another wall, thereby providing in the greenhouse movement of air which is closely similar to the atmospheric air in direction, strength and natural rhythm, whereby the plants cultivated in said greenhouse are closely similar in habit and growth to the same types of plants cultivated and grown in the open atmosphere, and in pots supported in respective recesses in trays, which in turn are supported on parallel, spaced, horizontal arms of racks supporting said trays above the floor of the greenhouse, the air circulating through the greenhouse passing through said racks.

Claim 4

Dependent Claim 149 words

A process for cultivating physiologically and morphologically valuable plants in greenhouses which comprises cultivating said plants in a greenhouse having openings in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of atmospheric air into openings in one wall and out of openings in another wall, thereby providing in the greenhouse movement of air which is closely similar to the atmospheric air in direction, strength and natural rhythm, whereby the plants cultivated in said greenhouse are closely similar in habit and growth to the same types of plants cultivated and grown in the open atmosphere, and in pots supported in respective recesses in trays, which in turn are supported on parallel, spaced, horizontal arms of racks supporting said trays above the floor of the greenhouse, the air circulating through the greenhouse passing through said racks.

Claim 5

Dependent Claim 43 words

A process as claimed in claim 2, and providing in the side wall of each of said recesses in said tray an overflow opening to allow a reservoir of water to accumulate in each recess up to the height of its overflow opening.

Claim 6

Dependent Claim 98 words

A plant cultivating device useful in greenhouse cultivation of plants comprising a rack having a plurality of parallel, spaced, horizontal arms, a plurality of trays resting on and extending between contiguous arms, and pot-forming members with soil therein and plants growing in said soil supported by said trays, said trays each having a plurality of upwardly opening recesses therein with the pot-forming members seated in respective recesses, said recesses comprising a side wall and a bottom wall, and each recess having in its side wall a hole through which excess water accumulated in the respective recess can overflow.

Claim 7

Dependent Claim 98 words

A plant cultivating device useful in greenhouse cultivation of plants comprising a rack having a plurality of parallel, spaced, horizontal arms, a plurality of trays resting on and extending between contiguous arms, and pot-forming members with soil therein and plants growing in said soil supported by said trays, said trays each having a plurality of upwardly opening recesses therein with the pot-forming members seated in respective recesses, said recesses comprising a side wall and a bottom wall, and each recess having in its side wall a hole through which excess water accumulated in the respective recess can overflow.

Claim 8

Dependent Claim 27 words

A plant cultivating device as claimed in claim 4, and projections on the bottom wall of said recesses supporting the respective pot-forming members above the bottom wall.

Claim 9

Dependent Claim 145 words

A greenhouse for cultivating physiologically and morphologically valuable plants, said greenhouse having openings in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of atmospheric air into openings in one wall and out of openings in another wall, thereby providing in the greenhouse movement of air which is closely similar to the atmospheric air in direction, strength and natural rhythm, and said plants being planted in pot-forming members with soil therein, and said pot-forming members being supported by a plurality of trays, and said trays in turn being supported by racks in said greenhouse, each rack having a plurality of parallel, spaced, horizontal arms with said trays resting on and extending between contiguous arms, whereby the air circulating through said greenhouse may circulate through said racks as well above said racks.

Claim 10

Dependent Claim 145 words

A greenhouse for cultivating physiologically and morphologically valuable plants, said greenhouse having openings in the lower portions of at least two side walls of said greenhouse to maintain circulation of air through the greenhouse by natural movement of atmospheric air into openings in one wall and out of openings in another wall, thereby providing in the greenhouse movement of air which is closely similar to the atmospheric air in direction, strength and natural rhythm, and said plants being planted in pot-forming members with soil therein, and said pot-forming members being supported by a plurality of trays, and said trays in turn being supported by racks in said greenhouse, each rack having a plurality of parallel, spaced, horizontal arms with said trays resting on and extending between contiguous arms, whereby the air circulating through said greenhouse may circulate through said racks as well above said racks.

Claim 11

Dependent Claim 145 words
