Problems solved by technology

Cornucopia usually shows a certain salt resistance ability under natural conditions, but its drought resistance ability is weak. Therefore, it is imminent to screen the drought-resistant and salt-resistant germplasm resources of ornamental plants or medicinal plants such as Qumai and improve the drought-resistant and salt-resistant ability.

Embodiment 1

[0036] A method for improving the salt resistance of Qumai, which specifically includes (1) selecting potted seedlings of biennial Qumai; (2) uniformly spraying salicylic acid with a concentration of 0.5mmol / L and 5-nitrogen with a concentration of 1.0mmol / L on the leaves. Sodium guaiacol mixed solution, the mixed solution is first prepared with the solutions of the above concentrations respectively, and then mixed according to equal volume ratio, sprayed once in the morning and evening, and sprayed on 1st, 3rd, and 5th for 3 days respectively.

Embodiment 2

[0038] The application of a method for improving the drought resistance of Qumai in regulating the expression of Qumai drought gene and alleviating the damage to Qumai plants caused by water stress, specifically includes (1) selecting annual potted seedlings of Qumai; 0.5mmol / L salicylic acid was sprayed once in the morning and evening, and sprayed continuously for 3 days. The water content of the potted quince was 50%.

Embodiment 3

[0040] The application of a method for improving the drought resistance of Qumai in regulating the expression of Qumai drought gene and alleviating the damage to Qumai plants caused by water stress includes (1) selecting biennial potted seedlings of Qumai; (2) spraying the leaves evenly Salicylic acid with a concentration of 0.5mmol / L is sprayed once in the morning and evening, and sprayed continuously for 3 days. The water content of the potted quince is 35%.

Abstract

The invention provides a method for improving the drought resistance and the salt resistance of dianthus superbus, and relates to the technical field of agricultural cultivation. Moisture is an important environmental factor affecting plant growth, drought conditions cause physiological and biochemical metabolism disorder of plants through ion poisoning and osmotic stress, so that growth and development of the plants are affected. Meanwhile, salt is an important environmental factor affecting plant growth, salt stress causes physiological and biochemical metabolism disorder of plants through ion poisoning and osmotic stress, and then growth and development of the plants are affected. The dianthus superbus generally shows certain salt resistance under natural conditions, but the drought resistance of the dianthus superbus is weak, so that research on screening of drought-resistant and salt-resistant germplasm resources of ornamental plants or medicinal plants and improvement of the drought resistance and salt resistance of the plants are extremely urgent. According to the method for improving the drought resistance and the salt resistance of dianthus superbus, drought resistance and salt resistance of ornamental plant or medicinal plant fringed pink are enhanced, comprehensive stress resistance of disease resistance, insect resistance and the like is improved, and growth of dianthus superbus is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for improving the drought resistance and salt resistance of quince. Background technique [0002] Qumai (Dianthus superbus L.), also known as wild wheat, osmanthus fragrans, ten bamboo flowers, ten kinds of scenery flowers, giant sentence wheat, etc., is a perennial herbaceous plant of the genus Dianthus in the family Caryophyllaceae (Huang Jian et al., 2011), and is a traditional Chinese medicine. , mainly used in the treatment of urinary system infections (Li Shuiqing et al., 2014). Because of its bright colors and few pests and diseases, it is often used in landscaping (Li Ying et al., 2011), and can also be used as potted plants, ground covers or cut flowers. Qumai, 50-60 cm high, flowering period June-September, fruit period August-October, when blooming, there are many flowers, dense growth, colorful and diverse colors, and it is an ornamental flo...
