Southern propagation and northern breeding method for plug seedlings of strawberries

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...

AI Technical Summary

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) nurseries, due to the long sunshine and hot climate from spring to autumn, the stolons of strawberry mother plants usually have a strong ability to produce stolons. However, the climate in warm southern regions is hot and humid. It is prone to diseases and insect pests, and the temperature in summer in warm southern regions is high, which is not conducive to the flower bud differentiation when harvesting in the later nursery
