Problems solved by technology

[0004] At present, the main problems of "Southern Fruits and Northern Planting" are: the investment cost in the protected cultivation of fruit trees is relatively high, and growers often hope that the fruit trees will be transplanted in the same year to achieve economic benefits in the same year, which requires 4-5 years of transplanting. tree, and it needs to be transplanted from the south to the north. At present, there is no relevant experience for reference in the northward migration of southern fruits. The huge difference between the transplanting of large trees and the transplanting environment results in a low survival rate of transplanting, such as transplanting for 1-2 years. Young trees can increase the survival rate, but they will bear fruit after 2-3 years of planting, resulting in an increase in operating costs

Embodiment 1

[0040] A method for cultivating tropical and subtropical fruits in protected areas in the north, specifically:

[0041] 1. Seedling selection: Take 180 4-year-old seedlings of Shiranui Zagan, which bear fruit in the first year and have 3 branches.

[0042] 2. Seedling domestication: It is divided into two steps: domestication of seedlings in the south and domestication of transplanting in the north.

[0043] The first step is to domesticate the seedlings in the south: In the seedling breeding base in Meishan, Sichuan, in late August 2017, the seedlings were pruned. The root system of the seedlings should be trimmed, and the vertical main roots with a thickness of more than 3 mm should be cut by 1 / 3, and the parallel capillary roots beyond the drip line of the seedlings should be cut off; then the seedlings should be put into degradable non-woven seedling bags, and filled with matrix soil. Then put the prepared bagged seedlings in the open space, close the seedling bags and th...

Embodiment 2

[0063] A method for cultivating tropical and subtropical fruits in protected areas in the north, specifically:

[0064] 1. Seedling selection: Take 100 'Big Five Star' loquat 5-year-old seedlings, fruit trees in the first year, with 5 branches.

[0065] 2. Seedling domestication: It is divided into two steps: domestication of seedlings in the south and domestication of transplanting in the north.

[0066] The first step is to domesticate the seedlings in the south: in the Zhejiang Pujiang seedling breeding base, in late August 2015, the seedlings were pruned, and the back branches, competing branches, leggy branches, etc. of the seedlings were cut off, and all the flowers and fruits of the year were cut off. Raise the seedlings and trim the root system, shorten the main root of the seedlings with a thickness of more than 3mm by 1 / 2, and cut off the parallel capillary roots outside the drip line of the seedlings; then put the seedlings into a degradable non-woven seedling bag a...

Abstract

The invention discloses a northern protected land cultivation method for tropical and subtropical fruits, and belongs to the technical field of fruit cultivation. The cultivation method comprises the steps of nursery stock selection, nursery stock domestication and nursery stock field planting; the seedling domestication comprises domestication in a southern seedling raising land and domestication in a northern transplanting land; according to the cultivation method, the survival rate of tropical and subtropical fruit trees transplanted in the north can be increased, current-year transplanting and current-year fruiting can be achieved, high yield can be achieved in the second year, and the average fruiting weight of each plant can be increased.

Description

technical field [0001] The invention belongs to the technical field of fruit cultivation, and in particular relates to a method for cultivating tropical and subtropical fruits in northern protected areas. Background technique [0002] With the adjustment of agricultural structure and the improvement of people's living standards, the people's requirements for high-quality specialty fruits are getting higher and higher, especially the demand for high-quality fruits in the south in the north is increasing. As a result, the quality of tropical fruits shipped to the north is not high, which seriously hinders the demand of the northern people for high-quality tropical fruits. [0003] At present, with the extensive application of protected cultivation techniques in the north and the rapid development of greenhouse insulation technology in advanced facilities, the border of subtropical fruit planting is gradually advancing to the north. The cultivation of subtropical fruits in nort...
