Problems solved by technology

Although it is known that 5-aminolevulinic acid enriches the stem of lawn grass, increases leaf density, and enhances the green color (Patent Document 2), it is still not sufficiently satisfactory to use 5-aminolevulinic acid alone.

Embodiment 1

[0043] Effects of 5-aminolevulinic acid hydrochloride and various gibberellin biosynthesis inhibitors on turfgrass dwarf promotion and stem enrichment

[0044] Cut the commercially available Zoysia sativa into 10×10 cm. Add a sufficient amount of volcanic ash soil (black volcanic soil) with a certain weight per pot in the container (1 / 44, 444×10a), and apply fertilizer (N-P-K=8-8-8) according to the nitrogen content of 2.6kg-N / 10a Fertilize and plant the cut Zoysia foliage. After confirming the survival of the grass, various gibberellin biosynthesis inhibitors and 5-aminolevulinic acid hydrochloride (treatment amount 600mg / 10a) were combined to treat the stems and leaves according to the treatment liquid amount 150L / 10a. After 26 days of treatment, the plant height was measured to check the dwarfing effect. In addition, since the combination of 5-aminolevulinic acid hydrochloride and the gibberellin biosynthesis inhibitor was shown to promote the growth of turfgrass stems, t...

Embodiment 2

[0059] Effects of 5-aminolevulinic acid hydrochloride and gibberellin biosynthesis inhibitor on leaf number increase and green improvement

[0060] Commercially available bentgrass was cut into circles with a diameter of 10 cm. Add a sufficient amount of volcanic ash soil (black volcanic soil) to the container (1 / 17, 500×10a), fertilize the liquid fertilizer (HYPONICA) with a nitrogen content of 3kg-N / 10a, and plant the cut bentgrass. After confirming the survival of the grass, combine the gibberellin biosynthesis inhibitor and 5-aminolevulinic acid hydrochloride (treatment amount 200mg / 10a) and carry out the stem and leaf treatment according to the treatment liquid amount 150L / 10a. After 30 days of treatment, the number of leaves of the lawn grass was measured with a magnifying glass, and the L of the lawn grass was measured with a color difference meter (manufactured by Konica Minolta). * a * b * .

Abstract

Provided is an agent for improving lawn grass qualities which has excellent effects of promoting dwarfing, fattening stem, increasing leaf count and improving green color. An agent for improving lawn grass qualities which comprises as the active ingredients 5-aminolevulinic acid or a derivative or salt thereof represented by general formula (1) and a gibberellin biosynthesis inhibitor: general formula (1) R2R1NCH2COCH2CH2COR3 (1) wherein R1 and R2 each independently represents a hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group, an aryl group or an aralkyl group; and R3 represents a hydroxy group, an alkoxy group, an acyloxy group, an alkoxycarbonyloxy group, an aryloxy group, an aralkyloxy group or an amino group.

Description

technical field [0001] The present invention relates to an agent for improving the quality of turfgrass, in particular, to a dwarfing promotion agent that suppresses elongation of turfgrass, enriches stems that increase stem weight, increases the number of leaves that increase leaf density, and improves greenness. Turfgrass quality improver with one or more effects of improving greenness. Background technique [0002] Turfgrass is widely used for sports, leisure, ornamental and security purposes, and is especially necessary for golf courses. In the management of turfgrass, pruning is harmful to the physiology of turfgrass, but on the other hand, by maintaining a suitable height, the density of stems and leaves is increased, and the germination of weeds is suppressed. Therefore, it is very important to maintain plant height by pruning. However, frequent pruning to maintain plant height requires labor, so dwarfing agents for turfgrass are used to reduce labor. [0003] Vari...
