A kind of cultivation method of plateau multi-flower bud strawberry seedling

Abstract

The invention provides a method for cultivating strawberry seedlings with multi-flowered buds on the plateau. The cultivating method comprises: cutting the stolons propagated by the strawberry mother seedlings in May into a seedling cultivation container with a single seedling volume of 255±10mL; Management makes the strawberry seedlings reach the root neck of 1.2cm or more in 60-90 days, the root system remains white and does not age, and the primary root accounts for more than 50% of the total mass of the root system; when the seedling age reaches 90-120 days, the total number of top flower buds and axillary flower buds are formed ≥2. In the cold and cool environment of the plateau, the invention realizes the cultivation of strong seedlings in the early stage and the regulation of flower bud differentiation in the later stage through fertilizer and water management, light and temperature regulation, container specification and seedling age control, which can not only promote the formation of top flower buds, but also prevent their abortion At the same time, it can also promote the differentiation of axillary flower buds, so that the flower bud differentiation period of strawberry seedlings is advanced by 40-60 days compared with the existing technology. After planting, it can mature within 60 days and achieve the effect of premature and high yield.

Description

technical field [0001] The invention relates to the field of strawberry planting, in particular to a method for cultivating plateau multi-flowered strawberry seedlings. Background technique [0002] Strawberries have high nutritional value, contain a variety of nutrients, and have health benefits, so they are deeply loved by people. At present, strawberries in facilities are mainly planted with conventional bare-root seedlings in the open field. The fruiting period of strawberries is generally from December to May of the following year, and the supply of strawberries exceeds demand at the initial stage of listing. Therefore, it is of great significance to promote the early differentiation and early fruiting of strawberry flower buds, which can not only improve the economic income of strawberry growers, but also meet the market demand. [0003] In recent years, the introduction of plug seedling cultivation technology can effectively prevent and control soil-borne diseases, a...

Problems solved by technology

[0004] Among the above four methods, except for alpine seedling cultivation, a large amount of labor and input costs are required, energy and labor are consumed, and large-scale seedlings are difficult to handle.

However, the existing alpine seedling cultivation has the problem of aborted flower buds, so it needs to be further improved to achieve premature and high yield of strawberries.
