Problems solved by technology

[0002] At present, most of the apple orchards produced in our country were built in the 1980s and 1990s, and now they have gradually entered the aging period. However, many apple counties lack enough land to build new apple orchards, and many places have to replant apples. Continuous cropping has not yet been resolved. Obstacles are bound to bring serious economic losses to fruit farmers
[0003] At present, the traditional methods and measures to overcome the obstacles of repeated cropping in production are time-consuming, laborious, pollute the environment, waste resources, and it is difficult to improve the losses caused by the obstacles of repeated cropping on a large scale.

Embodiment 1

[0026] Embodiment 1 Screening test of the present invention

[0027] The first stage: primary selection of anti-stubble materials

[0028] 1) Choose an old apple orchard more than 20 years old, remove the original trees, and remove the residual roots in the soil.

[0029] 2) Take the position of the original tree as the center, and mark the position of the hole of the original tree.

[0030] 3) Level the soil and try not to damage the original soil structure. Sow the layered apple rootstock seeds in the spring of the first year by broadcasting. Spread as evenly as possible, cover 1-2cm with topsoil in the rest of the area, and cover with mulch.

[0031] 4) Take the original tree cave as the center, set the area within a radius of 50cm around it as area A, and the area within 50cm around area A as area B, and so on; each area can be divided into multiple small areas with equal areas , It is convenient for investigation and statistics, during which the seedlings are normally...

Abstract

The invention relates to an in-situ breeding method for a three-phase breeding apple continuous-cropping-resistant stock. The method is capable of using the undeveloped land of apple continuous-cropping garden, performing the in-situ resistance breeding to various apple stock seedlings, verifying and obtaining the resistance stock material after preliminary screening. The method is used for improving the specificity and breeding efficiency of the continuous-cropping-resistant breeding, and greatly shortening the time cycle of the continuous-cropping-resistant stock breeding. The continuous-cropping-resistant capacity of the obtained plant material is strong, and the characters are stable. In addition, the method is suitable for performing the resistance stock screening in other fruit tree species and soil types (such as, breeding peach stock by using the undeveloped soil of the aged peach garden, performing the drought resisting stock breeding by using the drought soil, and performing the nematode-resistant stock breeding by using the soil of the aged grape garden), and provides the more effective apple continuous-cropping-resistant stock type for the production.

Description

(1) Technical field [0001] The invention relates to a three-stage in-situ breeding method for breeding apple rootstocks resistant to heavy cropping, belonging to the field of fruit tree breeding. (2) Background technology [0002] At present, most of the apple orchards produced in my country were built in the 1980s and 1990s, and now they have gradually entered the aging period. However, many apple counties lack enough land to build new apple orchards, and many places have to replant apples. The unresolved continuous cropping problem Obstacles are bound to bring serious economic losses to fruit farmers. [0003] At present, the traditional methods and measures to overcome the obstacle of repeated cropping in production are time-consuming, laborious, pollute the environment, waste resources, and it is difficult to improve the losses caused by the obstacle of repeated cropping on a large scale. If the targeted breeding of resistant rootstocks is to utilize the resistance of di...
