摘要:
The present invention provides a plant-activating agent for improving the activity of plants efficiently without a chemical injury onto the plant. The plant-activating agent is selected from the group consisting of (1) an organic acid derivative which is derived from the organic acid having two functional groups and wherein at least one of the above-mentioned functional groups is bonded to a group containing 1 to 30 carbon atoms; (2) a compound represented by the formula (II): RCOO(AO)nX1 (II) wherein R represents an alkyl or alkenyl group having 11 to 29 carbon atoms; X1 represents a hydrogen atom, an alkyl or acyl group having 1 to 30 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, or a counter ion; AO represents at least one group selected from oxyethylene, oxyprolylene and oxybutylene groups and may be random or block; and n represents an average number of moles added and is zero to 30; and (3) a glycerol derivative. If necessary, the agent is used together with a surfactant, a fertilizer component or a chelating agent.

The present invention provides a freshness-keeping agent for plants, such as a harvested plant, demonstrating an effect of keeping the freshness without selecting a type among various plants such as a harvested plant and also having a high safety. That is, the present invention provides a freshness-keeping agent for plants, such as a harvested plant, comprising a sugar derivative- or sugar alcohol derivative-based surfactant (A) and at least one selected from the group consisting of a sugar (B), a plant hormone (C), an aging inhibitor (D), an aggregating agent for colloidal particles (E) and a germicide, fungicide and preservative (F), preferably in a specific ratio by weight.

摘要:
The present invention provides a plant-activating agent which does not cause chemical injury on plants and which improves efficiently the activity of plants. The present invention uses a substance having not less than 5% of an improved degree in reproduction of green cells measured by a specific method as the plant-activating agent.
摘要:
The present invention provides a plant-activating agent which effects no chemical injury on plant and which makes an activity of plant improve efficiently. That is to say, the present invention provides a method of activating a plant, which comprises treating the plant with a mono-alcohol having 12 to 24 carbon atoms as a plant-activating agent; use of the mono-alcohol as a plant-activating agent; and a plant-activating agent or composition comprising the mono-alcohol; optionally with a surfactant, a fertilizer component and/or a chelating agent.

摘要:
A fertilizer absorption accelerator composition is provided which is capable of accelerating the absorption in a plant of such fertilizer components as calcium, nitrogen, phosphorus, and potassium. The composition is obtained by combining a fertilizer component with a surfactant and a heptonic acid or a salt thereof and is applied to the plant as sprayed to the surface of leaves thereof.
摘要:
The present invention provides an aqueous artificial medium comprising a water-absorbing polymer, which is suitable as a medium for cultivation in soil or hydroponic cultivation of plants. That is, the present invention provides an aqueous artificial medium and a polymer composition, comprising 0.01 to 10% by weight of a water-absorbing polymer and 0.001 to 10% by weight of a cationic polymer which is insoluble in water or an aqueous salt solution. Further, the present invention provides an aqueous artificial medium and a polymer composition, further comprising a porous water-supplying support having a communicating hole.
摘要:
An agrichemical-containing composition that exhibits excellent agrichemical efficacy is provided. The agrichemical-containing composition comprises hydroxypropyl cellulose, an agrichemical, an organic solvent having a saturated vapor pressure of 50 mmHg or higher at 25° C., and water. When the composition as a whole is taken as 100 wt %, the content of the organic solvent is 0.02 to 1 wt %, and the weight ratio of the hydroxypropyl cellulose to the organic solvent (hydroxypropyl cellulose/organic solvent) is in a range of 0.1 to 2.
