Problems solved by technology

[0005] However, there is no necessary relationship between the cold tolerance or frost resistance of turfgrass and the early rejuvenation and prolongation of green period of turfgrass. Northeast, Jilin, Heilongjiang and other very cold areas can be planted and grow normally for many years, known as "the leading grass species in the north", while tall fescue is a grass species with weak cold resistance, and it has survived for three years in the above areas. It will disappear in five years and is called a "short-lived perennial cool-season turfgrass", but the green period of bluegrass and tall fescue is similar; Zoysia is the most cold-resistant of warm-season turfgrasses Grass species, reflected in the early dormancy and yellowing period after the temperature drops, this is the plant's own protection mechanism, which is conducive to its resistance to the adverse effects of low temperature; coastal paspalum usually has a longer green period than zoysia grass, and the dormancy period is longer than that of zoysia. After the grass is pushed back, some varieties even remain green throughout the winter, but they often fail to turn green in the next year, indicating that their cold resistance is poor

Embodiment 1

[0017] The tiller of creeping bentgrass is planted in the pot (5x20cm) of full sandy soil, cultivates 60 days in the greenhouse, and greenhouse temperature is controlled at 23 / 20 ℃ (day / night), the relative humidity of 60%, 14 hours photoperiod, 680 μmol m -2 the s -1 During the cultivation period, the material was watered once a day, 1 / 2 Hoagland nutrient solution twice a week, and pruned weekly to maintain a canopy height of 2 cm. After the material grows closed, it is transferred to a growth chamber for pre-incubation before experimental treatments.

[0018] Creeping bentgrass leaves were sprayed with water (control) and 100mM betaine (treatment), and then the material was placed in a gradually lowering chilling stress for low-temperature acclimation. The temperature was set at 15 / 10°C (day / night) for 21 days, 10 / 10°C (day / night) for 15 days, 4 / 4°C (day / night) for 3 days and -2 / -2°C (day / night) for 3 days. GB was sprayed on the first day of chilling injury treatment, and...

Abstract

The invention discloses an application of GB in promoting turfgrass revival and prolonging green period. The invention discovers for the first time that the quality of turf where GB is sprayed under chilling injury stress and low-temperature domestication is remarkably higher than that of control. Agrostis stolonifera is transferred to an environment lower than 10 DEG C from a freeze injury environment, the green turf of a material where GB is sprayed is remarkably improved as compared with a material without GB spraying, and revival is brought forward.

Description

technical field [0001] The invention belongs to the field of lawn planting and maintenance management, and relates to the application of betaine in promoting lawn grass turning green and prolonging the green period. Background technique [0002] Betaine (GB) is a nitrogen-rich alkaloid that accumulates in chloroplasts. It can protect thylakoid membranes and maintain photosynthesis in plants under adverse conditions, thereby maintaining the normal life activities of plants. Exogenous application of GB can improve polytrophic Heat resistance, drought resistance, drought resistance, etc. of plant species. [0003] The promoting effect of GB on plant cold resistance mainly depends on the osmoregulation that can inhibit cell dehydration, and the antioxidant system in the ascorbic acid-glutathione cycle. In addition to GB, amino acids and carbohydrates can also accumulate during low temperature acclimatization, protecting cells from chilling and freezing damage. The main carbohy...
