摘要:
A material for optimizing and maintaining at least one of water, nutrients, biocides, and other protectant or growth supporting chemicals in natural soils by decreasing leaching, evaporation, and volatility through application of agglomerated granules (prills) formed of engineered hydrating particles, a binder, nutrients, and protectants to the soil. Typical application is by applying prills simultaneously with seeds when drilled, broadcast, or otherwise distributed.

A seed-containing crayon includes an elongated member formed of a marking composition to leave a colored mark on a surface when the elongated member contacts the surface. The marking composition is formed of a wax, a pigment, and a plant nutrient that is activated by application of water to the elongated member. Plant seeds are embedded in the marking composition of the elongated member. The crayon can include a paper band that at least partially surrounds the elongated member along at least part of the length of the elongated member in which the plant seeds are embedded.
摘要:
A granular seed germination facilitating and plant growth supporting media formed of a plurality of granules including at least a plurality of starch-containing granules each preferably composed of a pellet extruded from a starch mixture forming extruded seed germination facilitating and plant growth supporting granules each containing water-soluble starch that more immediately activates upon coming into contact with moisture and containing less water soluble, e.g., insoluble material including cold water insoluble starch which provides seed germinating and and/or plant growth promoting material over an extended period of time. Such a media can be used to germinate and and/or facilitate distribution of seeds. A plurality of extruded pellets can be attached to a single seed and a plurality seeds can be attached to a single extruded pellet producing seed carrying germination initiating starch-containing granules that can be used independently or together with the media.

A three-dimensional netted vegetation blanket with upright loops is manufactured by mechanically weaving a plurality of longitudinal, transverse, and loop-forming threads. The transverse threads are woven into a plurality of horizontal net bodies having a predetermined thickness and presenting a plurality of interlocked double-ply rings. The longitudinal threads are twisted threads having a predetermined strength, and are extended through the horizontal net bodies. The loop-forming threads are upward and downward extended through the interlocked rings of the horizontal net bodies to form a plurality of upright loops over any two parallelly adjacent horizontal net bodies, so as to give the netted vegetation blanket an enhanced structural strength and provide a 3D growing space for vegetation seeds. The 3D netted vegetation blanket has high void ratio to advantageously grow seeds and support seedlings, and thereby provides good effect in soil and water conservation as well as vegetation engineering works.
摘要:
A composition particularly adapted for use as a growing medium for grass. The composition, which includes prescribed proportions of water-absorptive wood fiber and non-water-absorptive cellulose particles (preferably rice hulls), is convenient to use and holds vast quantities of water for nourishing the germinating and growing grass plants. The composition's consistency inhibits its formation into an air-impervious sheet, which otherwise could reduce its effectiveness. In addition, when allowed to dry, the composition is extremely light in weight, which makes it easier to handle during harvesting and relatively inexpensive to transport.
摘要:
Methods for bonding two substrates, one of which is polymeric, which comprise coating the surface of at least one substrate with an adhesive composition comprising a major component which is an adhesive for the first substrate and a minor disperse phase which is a solution of a polymer in a solvent for the polymeric substrate and contacting the coated surface of the one substrate with the surface of the other substrate, together with adhesive compositions useful for joining such substrates, laminates so formed, and articles comprised of such laminates.
摘要:
Biodegradable-environmentally degradable transplanter containers are formed from a biodegradable thermoplastic polymer, e.g., poly(epsilon-caprolactone) or poly(ethylene adipate), and an environmentally degradable normally-solid ethylene polymer based composition.
摘要:
The invention disclosed provides a seed-foam-fabric composite which may be readily applied over a ground area for supporting and protecting seeds during germination.
摘要:
Composite materials of this invention include an absorbent layer and a non-absorbent layer, the absorbent layer having a textured surface for absorbing and trapping liquids, for example, oil, grease, or water, and the non-absorbent layer having an oleophobic surface that acts as an oil and grease specific liquid barrier. In one example, the surface texture includes a system of ridges and valleys that enhance the composite materials' ability to absorb and hold liquids. The material further includes one or more lamination layers. The lamination layer acts as a general liquid barrier between the absorbent layer and non-absorbent layer. This additional liquid barrier enhances the liquid repelling effect of the non-absorbent layer to more effectively trap liquids in the absorbent layer, thereby preventing liquids from seeping through the material onto an external surface.
