The present disclosure discloses a method for tomato soilless cultivation with suspended trough, including four aspects: setting of soilless cultivation substrate trough, preparation of soilless cultivation substrate, efficient and economical grafting and plant management. The efficient and economical grafting includes seedling raising, preparation of new scion, grafting and healing culture. The plant management includes planting, pruning and vine raising, flower and fruit management, and plant type maintenance. the present disclosure utilizes a soilless cultivation substrate trough, which can overcome the shortcomings of poor water retention, difficult control of temperature and water and fertilizer application in substrate bag cultivation and give full play to the characteristics of the cultivation substrate. The use of efficient and economical grafting and supporting plant management methods can optimize plants configuration, simplifying the work content of plant management, and improving the utilization rate of cultivation space.

The application provides a method for improving nutrient supply of female floral branches of Populus deltoides artificial hybridization. According to the technical links of the hybridization operation, the method separately integrates and improves the cultivation of female floral branch nutrient-supply seedlings (i.e., grafting rootstocks of floral branches), the pre-management of female floral branch nutrient-supply seedlings, the hydroponic management of floral branches, the Marching between female floral branches and rootstocks, the management of female floral branch nutrient-supply seedlings and the hydroponic management of female floral branches, so the goal of improving the seed-setting rate and quality of poplar hybrid seeds which came from the floral branches cultured in water has been achieved. Compared with the conventional method, the method of the invention not only can realize good seed quality, but also improve the seed-setting rate, and has a remarkable effect when applied to Populus deltoides artificial hybridization.

The present invention is a single blade clone cutter. The single blade clone cutter comprises a u-shaped housing with a single removable blade. The blade is locked into the u-shaped housing to secure the blade from moving during the process of cutting. It is important to have a single blade that cuts onto a flat surface so there is no damage being done to the fibers at the end of a cutting.

An electro-mechanical device cuts plant stems at a desired angle after a stem is inserted into a stem shaft and a sensor triggers activation of a blade along a blade path at a desired angle. A portable device powered by batteries can be used with plantings where they are growing or a powered device can be used for line production or high volume work.

A hand-held device cuts plant stems at a desired angle after a stem is inserted into a stem shaft and a blade is actuated along a blade path at a desired angle.

A plant propagation system is provided that includes a holder for holding at least two plants in relative spaced apart relation to enable a predetermined operation (such as, for example, a cutting operation) to be performed on each of the plants within the holder during a single pass.

A Tray and Trellis System includes vertical posts or legs, longitudinal members, and cross members. Combs include tines fixed at one end to longitudinal members on one side, and releasably engaged at their other end to other longitudinal members on the other side. Further combs include tines fixed to a cross member at one end, and releasably engaged to another cross member at the other end. There may be intermediate cross members having tines fixed to them and other tines releasably engaged to them. Fixation of the tines may be by clips, rings, welding, bonding, fastening, or by molding as a single piece. The releasably engaged ends of the tines may be engaged with snap-fit slot features in the longitudinal members, the cross members, or the clips or rings, or may be engaged with open grommets inserted into openings in the longitudinal members or cross members.

A grafting member including: a scion part including a first contact portion configured to contact a stem of a plant at a first position; a rootstock part detachable from the scion part, the rootstock part including a second contact portion configured to contact the stem at a second position located close to roots of the plant as compared with the first position; a first holder securable to the scion part, the first holder including a first press portion configured to press the stem of the plant against the first contact portion; and a second holder securable to the rootstock part, the second holder including a second press portion configured to press the stem of the plant against the second contact portion. A space is provided between the first holder secured to the scion part and the second holder secured to the rootstock part to expose the stem.

A grafting member including: a scion part including a first contact portion configured to contact a stem of a plant at a first position; a rootstock part detachable from the scion part, the rootstock part including a second contact portion configured to contact the stem at a second position located close to roots of the plant as compared with the first position; a first holder securable to the scion part, the first holder including a first press portion configured to press the stem of the plant against the first contact portion; and a second holder securable to the rootstock part, the second holder including a second press portion configured to press the stem of the plant against the second contact portion. A space is provided between the first holder secured to the scion part and the second holder secured to the rootstock part to expose the stem.
