Embodiment 1

[0033] (1) Variety selection, mother plant planting and maintenance:

[0034] ① Variety selection: select a short-day strawberry variety with more than 20 flowers in a single inflorescence, scattered flowering time of each single flower in the same inflorescence, and a single inflorescence flowering time span of more than 1 month; the selected variety name is "Zhang Ji" , the "Zhang Ji" variety can be purchased from the market.

[0035] ②Mother plant planting maintenance: Use a black plastic cylinder nutrition bowl as the mother plant planting container. The inner diameter of the mother plant planting container is 250mm and the height is 250mm. -4 centimeters is advisable, and described cultivation medium is to form with peat and perlite by peat: the volume ratio of perlite is 2:1;

[0036] On February 1, 2012, the seedlings of the "Zhang Ji" variety were planted in the mother plant planting container filled with the cultivation medium as the mother plant vegetative propagati...

Embodiment 2

[0046] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0047] In step (1), the variety is Xuexiang, which can be purchased in the market. During the maintenance of the mother plant Xuexiang, 200 milliliters of nutrient solution is poured per mother plant every day. The nutrient solution is an aqueous solution with a N content of 150 mg / liter, a P content of 25 mg / liter and a K content of 100 mg / liter. The pH value of the nutrient solution is 5.9, and the conductivity is 1.2ds / m.

[0048] In step (2), on June 20, on average, 32 seedlings were harvested per mother plant.

[0049] In step (3), the flower urging effect identification results are: 91% of the flower urging treated plants complete flower bud differentiation, and the flower urging plants begin to bloom from August 23 to September 2.

Embodiment 3

[0051] Embodiment 3 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0052] In step (1), on February 1, 2012, the "Zhang Ji" variety plug seedlings were planted in the mother plant planting container filled with the cultivation medium as the mother plant vegetative propagation of seedlings.

[0053] The greenhouse is set up in Yunnan Agricultural Science and Technology Park, located in Jiuxi Town, Jiangchuan County, Yuxi City, that is, in central Yunnan, with an altitude of 1680 meters, east longitude of 102.663 degrees, and north latitude of 24.276 degrees.

[0054] In step (2), on April 3, 13, 23, May 3, 13, 23 and June 3, a total of seven batches of newborn seedlings were planted. On June 17, an average of 40 seedlings were harvested per mother plant.

[0055] In step (3), short-day flower-promoting treatment:

[0056] On June 17, 200 seedlings of step (2) were placed in a small shed, and the natural light time...

Abstract

The invention discloses a method for producing short-day strawberry flowering seedlings in the central region of Yunnan province. The method comprises the steps of variety selecting, stock plant field planting curing, seedling breeding and short-day flowering processing. The short-day strawberry variety with the properties that the number of flowers in simple inflorescence is more than 20, the flowering time of a single flower in the same inflorescence is scattered, and the flowering time of the simple inflorescence lasts for one or more months is selected; the stock plant field planting curing, the seedling breeding and short-day flowering processing are carried out in the central region of Yunnan province with the altitude ranging from 1,600 meters to 1,900 meters; a nutrient solution including 100-150 milligrams per liter of N, 20-25 milligrams per liter of P and 80-100 milligrams per liter of K is used for watering the seedlings during the stock plant curing period, the seedlings are processed for 10 hours in the short day and processed for 30-35 days under the natural temperature condition, and flower bud differentiation is achieved in more than 90 percent of seedlings. The flowering cost is low, the flowering seedling supply time is early, 30-40 seedlings can be harvested in each stock plant in the middle ten days of June, the fresh autumn short-day strawberries can be produced, and normal winter and spring fresh strawberry production can be guaranteed.

Description

technical field [0001] The invention relates to a production method of short-day strawberry seedlings in central Yunnan, belonging to the field of agricultural technology. Background technique [0002] Strawberry (Fragara x ananassa Duch.), also known as pineapple strawberry, belongs to the genus Fragaria of the Rosaceae (Rosaceae). Strawberries are bright in color, soft and juicy, rich in aroma, sweet and sour, and rich in nutrition. They are deeply loved by consumers at home and abroad. Short-day strawberries have high sweetness and good flavor, and are currently the main species in production. This type of strawberry flower bud differentiation requires low temperature and short-day conditions. Under natural conditions, the flower bud differentiation is completed in autumn (September), and flowering and fruit bearing begin in early winter, and continue until the end of the next spring (under the cultivation conditions promoted by greenhouses in temperate regions; Dormanc...
