Cultivation method of plateau multi-flower bud strawberry seedlings

Abstract

The invention provides a cultivation method of plateau multi-flower bud strawberry seedlings. The cultivation method comprises the following steps: cutting stolons propagated by strawberry mother seedlings into a seedling culture container with the single seedling volume of 255+ / -10 mL in May, and enabling the strawberry seedlings to reach 1.2 cm or above of root necks in 60-90 days through lightand temperature regulation and fertilizer and water management, wherein the root system keeps white and does not age, and the primary root accounts for more than 50% of the total mass of the root system; and when the seedling age reaches 90-120 days, the total number of formed top flower buds and axillary flower buds is greater than or equal to 2. Under the plateau cold environment, through fertilizer and water management, light and temperature regulation and control, container specification and seedling age control and the like, early-stage strong seedling cultivation and later-stage flower bud differentiation regulation are achieved, formation of top flower buds can be promoted, abortion of the top flower buds can be prevented, and meanwhile, differentiation of axillary flower buds can be promoted. Compared with the prior art, the flower bud differentiation period of the strawberry seedlings is 40-60 days earlier, fruiting maturity can be achieved within 60 days after field planting,and the effects of premature yield and high yield are achieved.

Description

Technical field [0001] The invention relates to the field of strawberry planting, and more specifically, to a method for cultivating plateau multi-flower bud strawberry seedlings. Background technique [0002] Strawberry has high nutritional value, contains a variety of nutrients, and has health benefits, which is deeply loved by people. At present, facility strawberries are mainly planted with conventional bare-root seedlings. The fruiting period of strawberries is generally from December to May of the following year, and the supply of strawberries is in short supply at the beginning of the market. Therefore, promoting early differentiation and early fruiting of strawberry flower buds is of great significance, which can not only increase the economic income of strawberry growers, but also meet market demand. [0003] In recent years, the introduction of plug seedling cultivation technology can effectively prevent soil-borne diseases and achieve early fruiting by shortening the sl...

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.
