Embodiment Construction

[0015] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] The embodiment of the present invention provides a method for cultivating apple hybrid seedlings, which uses cold storage to refrigerate the hybrid fruit instead of layering, collects the hybrid seeds at an appropriate time, sows them in a nutrient bowl in a greenhouse, manages them (including hardening), and finally transplants them in a nursery And post-planting management, specifically include the following steps:

[0017] S1. Refrigerated hybrid fruit: Harvest fully mature hybrid fruit, put it in a plastic fruit basket with holes, and refrigerate it in a cold storage at 1-4°C;

[0018] S2. Collection of hybrid seeds: collect apple hy...

Abstract

The invention discloses a method for cultivating apple hybrid seedlings. The method includes the following steps: picking up ripe apple hybrid fruits, and storing the ripe apple hybrid fruits in a refrigeration house at the temperature of 1-4 DEG C; acquiring hybrid seeds from the apple hybrid fruits stored in the refrigeration house, and using clean water to clean the hybrid seeds; preparing a bed with the width of about 1 meter in a greenhouse, putting a medium in nutriment pots, straightening the medium in the bed, watering the medium thoroughly, and allowing the medium to stand for 2-3 days; sowing the cleaned hybrid seeds in the nutriment pots, covering the hybrid seeds with wet nutriment soil with the thickness of 1 cm, and controlling the temperature of the greenhouse at 25-30 DEG C; changing the temperature of the greenhouse to 20-25 DEG C when the height of hybrid seedlings is 5-10 cm, keeping the relative humidity at 50-70%, performing ventilation at suitable time, transplanting the hybrid seedlings to a nursery garden after the hybrid seedlings are cultivated for 15-20 days, watering the hybrid seedlings once after transplanting, and performing management after planting. The method can avoid sand storage and germination accelerating in an apple hybrid seedling cultivation process, is easy to operate, and can improve the rate of emergence by about 25%.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a method for cultivating apple hybrid seedlings. Background technique [0002] Apple is one of the main fruits in the world. The apple industry is the main source of income for farmers in apple-producing areas in my country and the leading industry for poverty alleviation. Excellent varieties are the core elements of the development of the apple industry. At present, the breeding of new apple varieties is still dominated by hybrid breeding, and the cultivation of apple hybrid seedlings is the most critical in the process of apple hybrid breeding. [0003] The steps of cultivating apple hybrid seedlings are complicated and the technical requirements are high, and a little inappropriateness will lead to a low emergence rate and seriously affect the progress of apple breeding. Contents of the invention [0004] In order to solve the above problems, the invention provides...
