Problems solved by technology

However, the shortcomings of strawberry seedling cultivation in cold and cool mountainous areas are short phenological period, weak stolon generation ability during seedling cultivation, and strong wind in spring in these areas, which is not conducive to stolon reproduction, so the number of stolon seedlings that can be used for plug seedling cultivation is insufficient
[0004] In southern (Yunnan and other places) nur...

Embodiment 1

[0045] This embodiment relates to a method for breeding strawberry plug seedlings from south to north, comprising the following steps:

[0046] 1) In March, strawberry varieties such as Hongyan, Jingzangxiang, Xiangye, Zhangji, Jingtaoxiang, and Sweet Charlie were cultivated at an altitude of about 1,500m in central Yunnan to make them grow a large number of stolons. During the cultivation process, far-infrared strawberries were used to Light is carried out light treatment to it, and the concrete condition of described treatment is that 10 days after planting fruit grows leaves, with the high beam lamp that power is 60w, 2m away from plant is irradiated, each time irradiates 2.5~3.5 hours, treats four weeks altogether;

[0047] 2) In June-July-August, the strawberry stolons are pre-cooled and transported to the Bashang area in the north of Beijing-Tianjin-Hebei region by cold chain. During the cold chain transportation, the temperature of the strawberry stolons is kept at 0-4°C...

Embodiment 2

[0053] This embodiment relates to a method for breeding strawberry plug seedlings from south to north, comprising the following steps:

[0054] 1) In March, strawberry varieties such as Hongyan, Jingzangxiang, Xiangye, Zhangji, Jingtaoxiang, and Sweet Charlie were cultivated in the north-central region of Hainan to make them grow a large number of stolons. Carry out spray treatment, the hormone is the combination of cytokinin and gibberellin solution, the concentration of said cytokinin is 1200ppm, and the concentration of said gibberellin is 300ppm;

[0055] 2) In June-July-August, the strawberry stolons are pre-cooled and transported to Changzhi, Shanxi by cold chain, and the temperature of the strawberry stolons is kept at 0-4°C and the humidity is 80-90% during the cold-chain transportation , and transported to the destination within 24 hours; after the stolons were transported to the cold and cool area in the north, they were placed in a cool place before cutting, sprayed...

Abstract

The invention relates to a southern propagation and northern breeding method for plug seedlings of strawberries. The southern propagation and northern breeding method comprises the following steps: 1)breeding strawberries in a warm and suitable area in the south in spring to grow a great number of healthy creeping stems; and 2) transporting the creeping stems to a cold and suitable area in the north in summer, and breeding the creeping stems by using a plug seedling raising method until the creeping stems blossom and bear fruits. According to the southern propagation and northern breeding method, the creeping stems of the strawberries are propagated and bred by sufficiently utilizing the warm climate in a specific region in the south in spring, and then, blossom buds of the seedlings of the strawberries are promoted to differentiate by utilizing advantages of the climate in a cold area of a specific region in the north in summer.

Description

technical field [0001] The invention relates to the technical field of strawberry seedling cultivation, in particular to a method for growing strawberry plug seedlings from south to north. Background technique [0002] In recent years, the strawberry industry has become a pillar industry in many areas of our country, and has produced huge social and economic benefits. The scale of strawberry planting and the demand for seedlings in my country have become the first in the world. The main season for strawberry seedlings is from spring to late summer and early autumn. In spring, seedlings are propagated through stolons. The higher the temperature, the greater the propagation coefficient of stolons. The shorter the sunshine in late summer and early autumn, the lower the temperature, the more conducive to the flower bud differentiation of seedlings, and the less pests and diseases. However, regions with warm spring and cool summer climate are very rare, which limits the nursery's...
