Sweet cherry seedling raising and garden establishing method in high altitude cool areas

Abstract

The invention provides a sweet cherry seedling raising and garden establishing method in high altitude cool areas. The method comprises five steps as follows: grafted variety and stock selection; stock breeding; collection and storage of scions; grafting operation and management; and nursery stock transplanting and final-period management. The method using the technical scheme has the beneficial effects that the survival rate of single plant nursery stock is improved by 95% when sweet cherry seedlings in the high altitude cool areas at the altitude of 2200 to 2600 m and the mean annual temperature of 9 to 13 DEG C are grafted, the transplanting survival rate of the nursery stocks during garden establishing is improved to more than 95%, and the transplanted nursery stocks are vigorous in growth and relatively high in resistance; the juvenile phase of fruit trees is shortened, and the single plant yield in the third year after cultivation can reach more than 1.50 kg; a traditional cultivation pattern that mainly-planted variety and pollination variety are matched for planting is changed, the management cost is reduced while early fruiting and high yield in the garden are realized, and the economic benefit of the garden can be improved by more than 30%.

Description

technical field [0001] The invention relates to a method for cultivating fruit tree seedlings, belonging to the field of plant cultivation, in particular to a method for cultivating sweet cherry seedlings and gardening in high-altitude and cool regions. Background technique [0002] At present, in high-altitude and cool areas with an altitude of 2200-2600m and an annual average temperature of 9-13°C, the usual method for planting and building sweet cherry gardens is to use Gisela series or rootstocks such as Daqingye and Maocherry, and each A variety of sweet cherry is grafted on the rootstock, and the grafted sweet cherry seedlings are transplanted with bare roots in autumn and winter or before the plants germinate in spring, and the main species and pollinated varieties are planted in a certain proportion. [0003] The main disadvantages of this method are: 1. Due to the high-altitude and cool area with an altitude of 2200-2600m and an annual average temperature of 9-13°C,...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of this method are: 1. Due to the high-altitude and cool area with an altitude of 2200-2600m and an annual average temperature of 9-13°C, the temperature is low from winter to early spring, and the temperature varies greatly, which is easy to cause freezing damage. As a result, the survival rate of transplanted sweet cherry seedlings is low; 2. Due to the high-altitude and cool areas with an altitude of 2200-2600m and an annual average temperature of 9-13°C, the effective accumulated temperature during the growth period of sweet cherry seedlings is low, and the growth period of the plants is relatively low. Shorter, resulting in weak growth of seedlings, long childhood, and late fruit bearing; 3. Because the main planting varieties and pollinating varieties have different requirements for soil, water, fertilizer and other cultivation conditions, differentiated and fine management is required, which makes orchard management more difficult , the cost of production becomes higher, thereby reducing the orchard's income
