US-20260123591-A1 - APPARATUS AND METHODS FOR PLANT POLLINATION

Abstract

Embodiments of the present disclosure relate to apparatus and methods for mechanized pollination. Grow towers vertically disposed on a grow line are moved into a pollination chamber and mechanized pollination is performed utilizing pneumatic, acoustic, or mechanical methods to pollinate plants growing in the grow towers. In one embodiment, a plurality of rotatable brush towers are disposed on opposite sides of the grow line and bristles from the brush towers are rotated over the plants to facilitate pollination as the grow towers traverse along the grow line. In another embodiment, a plurality of conduits internal to the grow towers are coupled to one or more nozzles on a face of the grow towers. Pollen is delivered through the nozzles toward the plants utilizing pressurized gas.

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Divisional of U.S. application Ser. No. 18/027,539 filed Mar. 21, 2023 which is a National Phase Application under 35 U.S.C. 371 of International Application No. PCT/US2021/051427, filed Sep. 22, 2021, which claims priority to U.S. Provisional Patent Application No. 63/082,984 filed Sep. 24, 2020, all of which are herein incorporated by reference in their entirety. BACKGROUND Field Embodiments of the present disclosure generally relate to environmentally controlled indoor agricultural systems. More specifically, embodiments of the present disclosure relate to apparatus and methods for plant pollination. Description of the Related Art Conventional agricultural practices have evolved rapidly over the twentieth century to what can now be considered a fast-moving high-tech industry. Global food shortages, climate change, a societal changes instigated a transition from manually implemented agriculture techniques toward advanced farming methods, such as mechanized and automated farming. While conventional agricultural practices often limit a farmer to one growing season, indoor farming can eliminate environmental constraints and increase crop production. However, commercial scale controlled environment agriculture is still in its relative infancy when compared to conventional agricultural practices. Although there exists great potential for production of many different types of plants in controlled environment agriculture, plants requiring pollination for produce production present additional challenges to successful implementation. For example, conventional agricultural practices utilize naturally occurring pollination vectors, such as bees or the like, to facilitate pollination. Effective implementation of live pollination vectors in controlled environment agricultural systems is an additional challenge and is not well developed. Thus, what is needed in the art are improved apparatus and methods for plant pollination. More specifically, what is needed are improved mechanized pollination apparatus and methods for controlled environment agriculture systems.
