Problems solved by technology

In recent years, the rain-sheltered rack-type seedlings have been introduced in production. This technology is highly sought after by the market because of its labor-saving and high efficiency. However, due to the large amount of planting of the mother plant, the investment cost of seedlings is high. At the same time, the time for planting is too long and the supply of fertilizer and water is unreasonable. , the root of the mother plant is easy to age during the high temperature period, and it is difficult to maintain the growth of the plant, resulting in a decrease in the quality of the stolon seedlings. It is urgent to improve this technology to reduce production costs and improve efficiency

Embodiment 1

[0024] A method for secondary seedling raising of strawberries, comprising the steps of:

[0025] (1) Planting of mother plants: On October 25, 2018, 60 original seedlings of "Ningyu" were planted in flowerpots of plastic greenhouses, with an inner diameter of 20cm and a height of 16cm. The matrix ratio was peat: coconut bran: perlite = 5:3:2, routine management to keep warm and moisturizing;

[0026] (2) Mother plant management: From November 10th to February 8th, 2019, cover the film for heat preservation according to the temperature change to ensure that the temperature in the shed is not lower than 5 °C to prevent dormancy; from February 9th to April 17th, after the temperature rises, pass The method of closing the shed early and opening the shed late is the night temperature of 12°C, to ensure that the stolons are continuously pumped, and conventional fertilizer and water management;

[0027] (3) Secondary mother plant cultivation and field planting: On April 17th, the s...

Embodiment 2

[0031] This example is basically the same as Example 1, the difference is that in the fertilizer and water management of the secondary mother plant, 4.5 mg of nitrogen-containing fertilizer per plant was applied on April 24, and the initial frequency was once every 5 days for 4 consecutive times. Once in 7 days, each time increases by 1.5mg per plant, 8 times in a row, accumulatively 112mg / plant, according to the characteristics of "Ningyu" stolon extraction, it provides sufficient nutrition for the secondary mother plant, and promotes the extraction of robust seedlings from the plant; independent In the cutting and cultivation of seedlings, 7-10 days after the cutting, new leaves and new roots will grow. Start to apply nitrogen fertilizer 4.5mg / plant. The initial frequency is once every 5 days, 4 times in a row, with a total of 18mg / plant. Entering August Control off nitrogen fertilizer, promote flower bud differentiation, and routine light treatment.

Abstract

The invention belongs to the technical field of horticultural strawberry seedling breeding, and discloses a strawberry secondary seedling raising method, including mother plant planting, mother plant management, secondary mother plant cultivation and planting, secondary mother plant fertilizer and water management, and independent seedling cutting and cultivation steps. Under the conditions of facility greenhouses, the present invention promotes early extraction of seedlings from the mother plant, uses the extracted seedlings as the secondary mother plant, optimizes the supply of fertilizer and water according to the stolon extraction rules of different strawberry varieties, and maintains the strawberry mother plant during the high temperature period. The growth and stolon pumping ability can effectively improve the breeding quality of strawberry varieties. The strawberry secondary seedling raising method provided by the present invention provides a new approach and technical support for the supply of strawberry seedlings and the breeding of strong seedlings, thereby establishing a strawberry annual seedling raising technology system, forming an independent research and development, and an integrated application technology, which is of great importance to strawberry in my country. The sustainable and steady development of the industry is of great significance.

Description

technical field [0001] The invention relates to a secondary seedling raising method of strawberry, belonging to the technical field of strawberry seedling breeding. Background technique [0002] Since the founding of New China, great achievements have been made in the scientific research of strawberries in my country. According to incomplete statistics, the strawberry area in China reached 173 333hm in 2018 2 , The total output is 5 million t, and the cultivation area and output rank first in the world. Strawberry is a vegetatively propagated crop, and seedling breeding is an important part of strawberry production. With the vigorous development of the strawberry industry, high-quality seedlings are not only the key to the high yield of strawberries, but also a new economic growth point for the strawberry industry. [0003] As China has entered an aging society, strawberry cultivation methods have gradually shifted to labor-saving rack cultivation. One of the main measure...
