Embodiment 1

[0036] Implementation location: In the greenhouse at the base of the Flower Research Institute of Yunnan Academy of Agricultural Sciences, Kunming City, Yunnan Province, at an altitude of 1896 meters.

[0037] (1) Mother plant selection and colonization

[0038] ① Install multiple rows of supports on the ground in the greenhouse, and place a strawberry cultivation trough on each support. The distance between two adjacent strawberry cultivation troughs is 1.1 meters; the notch of the strawberry cultivation trough is 100 cm away from the ground; 20 centimeters in width, 20 centimeters in width at the bottom, and 20 centimeters in height; the cultivation substrate is filled in the strawberry cultivation tank, and the cultivation substrate is mixed by peat and perlite at a volume ratio of 7:3 of peat: perlite; support and strawberry cultivation groove The amount is determined according to the production volume.

[0039] ②Tissue-cultured virus-free seedlings of short-day strawberr...

Embodiment 2

[0055] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0056] Implementation location: Yunnan Agricultural Science and Technology Park, Jiangchuan County, Yuxi City, Yunnan Province, with an altitude of 1680 meters.

[0057] Step (1) In the selection and planting of the mother plant, 'Taoxun' (ginkgo strawberry) was added to the variety; the planting date of the mother plant was August 31, 2014, and the distance between the strawberry cultivation tanks was 1.2 meters. The width is 25 cm, and the height is 25 cm; the mother plants are planted in double rows in the strawberry cultivation tank, the row spacing is 15 cm, the plant spacing is 25 cm, and 4400 plants are planted per mu.

[0058] Step (3) During the seedling propagation stage, mother plant maintenance and seedling harvesting, the two seedling harvesting dates were June 6, 2015 and August 6, 2015, respectively. 'Zhang Ji', 'Hongyan' and ' The ...

Embodiment 3

[0061] Embodiment 3 is the same as Embodiment 2 except that the following measures are different, and will not be repeated here.

[0062] Step (4) ③ place the hole tray with the seedlings inserted in the open field (embodiments 1 and 2 are in the greenhouse), and on the 43rd day after cutting, the outer wall of the cultivation substrate in the holes of the hole tray is covered with new roots of the inserted seedlings, The plug seedlings are the strawberry plug seedlings produced, which can be transplanted to produce fresh strawberry fruits. 'Zhangji', 'Hongyan' and 'Taoxun' had an average of 67, 62 and 67 cuttings per mother plant, respectively, and the seedling numbers of 'Zhangji' and 'Hongyan' were slightly higher than those in the greenhouse. The survival rate of cuttings of 'Zhang Ji', 'Hongyan' and 'Taoxun' reached 98.5%, 98.4% and 95.7% respectively.

Abstract

The invention provides a high-quality, efficient and economical production method of strawberry plug seedlings. The method comprises the main technical measures that tissue culture virus-free seedlings are selected as mother plants, and soilless culture is adopted in mother plant cultivation, juvenile seedling breeding and cutting; hybrid and bad plants are removed in the mother plant fruiting period, and transparent and colorless film mulching is conducted after juvenile seedling cutting; reproductive growth of the mother plants is controlled, and nitrogen fertilizer supply is increased. Health, high quality and high production efficiency of the seedlings are guaranteed, and the dependence degree of the cutting link on facilities is decreased; the mother plants are subjected to field planting in autumn and subjected to breed seedlings in summer after fruiting in winter and spring, the mother plants can produce juvenile seedlings in summer, each mother plant can produce 60-70 juvenile seedlings in summer, the mother plants can produce fresh fruits in winter and spring, and 300-400 g of fresh fruits can be harvested from each mother plant; the production cost is effectively shared, the strawberry plug seedling production time is short, the cutting seedlings reach the field planting standard 40 days after cutting, the cutting survival rate is high and reaches 93% or above, high-quality, efficient and economical production of the strawberry plug seedlings is achieved, the practical value is high, and the method can be applied to practical production in a large scale.

Description

technical field [0001] The invention relates to a high-quality, high-efficiency and economical production method for strawberry plug seedlings, belonging to the technical field of agricultural planting. 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. [0003] Short-day strawberries have high sweetness and good flavor, and are currently the main species in production. This type of strawberry begins to bloom and bear fruit in early winter under the cultivation conditions promoted by greenhouses in temperate regions, and lasts until early summer of the following year; under open field conditions, the plants dormant in winter, and bloom and bear fruit in the next spring; stolons begin to germinate in late spr...
