Novel method for efficient and rapid seedling establishment of strawberry stolons

Abstract

The invention discloses a novel method for efficient and rapid seedling establishment of strawberry stolons. The method comprises the following seedling establishment steps of strawberry stolon inducing, stolon cutting, grading and preprocessing, aerial root inducing, transplanting and seedling establishment. The method can be used for efficient and rapid seedling establishment of elevated stolons of excellent new strawberry species of Hongyan, Zhangji and the like. According to the novel method, the defect that rooting of stolons formed early is difficult is overcome, and by inducing the early stolons to generate aerial roots and then transplanting the stolons to a substrate and adopting a mode of short-term darkness culture, efficient and rapid seedling establishment of the strawberry stolons is achieved. By means of the novel method, the seedling establishment rate is generally 85%-89% or above, and the advantages of being simple, convenient to operate, high in seedling establishment speed and the like are achieved. Compared with cuttage, the method for inducing the stolons to generate the aerial roots is simple and convenient, and needed time is short and concentrated; the quality of offspring stolon seedlings generated through the method in different times and different batches is high and more stable.

Description

technical field [0001] The invention belongs to the technical field of seedling raising of horticultural crops, and in particular relates to a new method for efficiently and quickly growing seedlings of strawberry stolons. Background technique [0002] Strawberry is a perennial herbaceous plant belonging to the Rosaceae Strawberry genus. It has the characteristics of strong adaptability, short production cycle, quick effect, and high income. It is also rich in protein and vitamins. It is known as the "Queen of Fruits" and is well received by producers and consumers. of favor. Using solar greenhouses, plastic greenhouses and other facilities to cultivate and cooperate with corresponding technical measures can make strawberries go on the market in advance and become high-quality fruits during major festivals such as Christmas, New Year's Day, and Spring Festival, and the economic benefits are very considerable. [0003] Despite the remarkable development of strawberry protect...

Problems solved by technology

[0003] Despite the remarkable development of strawberry protected seedling breeding technology, due to various reasons, most growers still adopt the relatively simple and extensive open field stolon breeding method for self-propagation and self-use for a long time, resulting in frequent viral diseases in strawberry seedling breeding occurrence, serious variety degradation, serious anthracnose infection, low reproduction coefficient, uneven abundance, and serious soil-borne diseases, which increase the risk of production

[0004] While the above-mentioned problems increase production costs and increase production risks, they also seriously restrict the rapid promotion of excellent strawberry varieties.

Especially in recent years, the large-scale planting of some excellent varieties such as Hongyan and Zhangji has been welcomed by producers and consumers because their fruit quality is obviously better than that of old varieties such as Mingbao and Fengxiang. However, the seedling cultivation of these new varieties is difficult a difficulty

At present, some professional strawberry seedling breeding companies mainly use the stolons pumped on the elevated to plant the nutrient pots on both sides of the suspension or cut the stolons for cutting seedlings. Although the above methods can breed a large number of seedlings, but It is labor-intensive and time-consuming, and the adventitious roots formed on the stolons are gradually necrotic due to the long exposure time, so the seedling rate of cutting seedlings is relatively low, and the time required for seedlings is relatively long, which affects the popularization and application of strawberry elevated seedlings.
