摘要:
A reactor includes a reaction vessel that defines a reaction chamber. Completely or partially within the reaction chamber is at least one spiroid. The spiroid is operably associated with the reaction vessel so that rotation of the reaction vessel causes the spiroid to rotate and liquid to be transferred through the spiroid. The spiroid can circulate gas and liquid within the reaction chamber, introduce fresh gas and liquid into the reaction chamber or discharge gas and liquid from the reaction chamber.
摘要:
A field transplant system including a machine for sequentially forming groups of polymerized soil plugs having seed receiving recesses in one end thereof and supported on a carrier, and in certain cases interconnected by strips, the carrier being used to transport the soil plugs through a seeding station and then to a germination station and then to a growing station either in the flat or on a plant turning machine in a greenhouse to grow the germinated seeds to transplant size, and then using the carrier to transport the soil plugs with the transplants growing therein to the field for transplanting by an automatic transplanter; several forms of soil plugs are disclosed, and several methods for supplying seeds to the soil plugs are disclosed, as well as an improved method of mounting a mat of soil plugs on the cylinder of a plant turning machine.
摘要:
Composition for the regulation and promotion of the growth rate and characteristics of a variety of plants by providing a method for increasing the concentration of N-.sup.6 -Benzyladenine in a concentrated solution of a solubilizing agent including a selected alcohol(s) or hydroxy compound(s), such as a glycol and a selected hydroxide. Included is a method of preparing a plant growth promoter concentrate from stable water dilutable liquid concentrates of N.sup.6 Benzyladenine, ("N.sup.6 BA"). A process of increasing iron absorption by plants utilizes a method of uniformly coating dry powdered humic acid and seaweed with a N.sup.6 BA concentrate solution by preparing a solution of N.sup.6 BA concentrate solution comprising an alcohol and an alkaline metal hydroxide, applying the N.sup.6 BA concentrate solution to a mixture of dry powdered humic acid and seaweed, evaporating the residual alcohol through low temperature drying forming a caked material, pulverizing the caked material to a powdered form, and suspending the finely powdered concentrate in an aqueous spray solution.
摘要:
A continuous molding machine (10) for forming two chains (55) of soil plugs (50) for use in germinating seeds or otherwise growing plants. A continuous sheet of paper (22) is corrugated to conform to a series of mold elements (14) and a reaction mixture (32) of polymerizing agent and soil slurry is added over the paper to conform to the mold element shape. Another sheet of paper (38) is added over the top of the mixture (32) and the entire assembly is then passed under a series of pressure belts (42, 44, 46) during which time the mixture (32) is cured. The chain of soil plugs (50) which emerges from the pressure belts (42, 44, 46) is encased on both sides by paper (22, 38) and may be cut to provide a pair of separate soil plug chains (55).
摘要:
A method of forming a hydrophilic urethane prepolymer comprising the steps of reacting an isocyanate compound to a hydrophilic polyether or polyester compound which has been heated to such a temperature that the temperature of the reactants after addition of isocyanate is at least as high as about 120.degree. C. The resulting urethane prepolymer may be reacted with water to form a cellular urethane polymer.
摘要:
A rooting media in the form of a resilient, integral body of spongy open-celled hydrophilic polymer forming a first essentially continuous phase extending throughout the body and having passages therethrough forming a second essentially continuous phase extending throughout the body, a quantity of particles of soil mixture distributed throughout the body of spongy polymer and held thereby with a substantial portion of the surface area of the particles of soil mixture exposed and in communication with the passages, the exposed particles of soil mixture providing colloidal contact exchange surfaces in communication with the passages and having collectively a porosity maintenance capacity and a water holding capacity and an ion exchange capacity and a pH buffering capacity; also disclosed is a method of making such a body of rooting media, as well as a release agent useful in that method; there further is disclosed a particular form of rooting media for use in propagation by air layering and a method of propagation by air layering.
