Field strawberry mother seedling culture device and culture method thereof

Abstract

A field strawberry mother seedling culture device comprises a device body, the body is a matrix container, the interior of the container is of a double-layer structure, the inner layer is a culture layer for containing mother seedlings, the outer layer is a heat preservation layer, a transversely-arranged groove for containing a film is formed in the top of the matrix container, and the height of the two sides of the groove is larger than that of the middle of the groove. A rectangular handheld part with the two sides protruding is formed, a handheld handle is arranged on the handheld part, extraction is convenient, and a plurality of positioning corners are further arranged on the two sides of the bottom of the container. According to the method, the growth time of the mother seedlings on the production seedlings is shortened, the influence on the production seedlings is reduced, and the disease infection rate of the mother seedlings is greatly reduced; mother seedlings without stolons are free of a rejuvenation period, management is simple, and the survival rate reaches up to 99%.

Description

technical field [0001] The invention relates to a field strawberry mother seedling cultivation device and a cultivation method thereof, belonging to the technical field of plant cultivation. Background technique [0002] Strawberry is a perennial evergreen herb belonging to the Rosaceae family. Strawberry has wide climate adaptability, wide production areas, and various cultivation methods. It is suitable for both open field cultivation and facility cultivation. At present, the top ten strawberry production countries in the world are China, the United States, Mexico, Turkey, Spain, Egypt, South Korea, Poland, Russia and Japan. The large-scale production of strawberry commodities in my country began in the 1980s. Because of its popularity with consumers and high planting benefits, the area of ​​strawberry cultivation expanded rapidly. In 1985, the national planting area was less than 50,000 mu. In 1995, it increased to 550,000 mu. In 2001 It reaches 900,000 mu annually. In ...

AI Technical Summary

Problems solved by technology

At present, most of the mother seedlings used for strawberry stolon propagation method are cultivated by clipping stolon cuttings for overwintering in the field. The stolons need to stay on the field production seedlings for more than one month to grow roots and grow strong seedlings. During this period, they are susceptible to diseases. Consuming the nutrition of the production seedlings affects the flower bud differentiation and yield of strawberries; in addition, when cutting the stolons, because they are bare-rooted seedlings, it takes a long time to slow down the seedlings, the survival rate is affected, and management is troublesome
