Blueberry seed selection and breeding method

Abstract

The invention discloses a blueberry seed selection and breeding method, which comprises the following steps of seeding bed preparation: uniformly mixing rotten moss, turf and river sand; watering a substrate so that the substrate keeps wet; cutting: selecting 1-2-year branches without plant diseases or insect pests; trimming a cutting opening into an inclined opening; putting a cutting branch into rooting nutrition liquid for 2 to 20 minutes; taking out the branches; vertically inserting the branches into the substrate; spraying water; temperature and humidity control: controlling the temperature to be 22 to 27 DEG C; watering the substrate so that the substrate keeps wet; fertilizer management: starting to apply fertilizers in a liquid state after the cutting branch roots; transplanting: transplanting the rooting seedling into a nutrition pot to be cultured. The blueberry seed selection and breeding method has the advantages that the cutting breeding is mainly used; the method is simple; the implementation is easy; the seedling forming speed is high; the survival rate is high; the ventilation and the watering need to be frequently performed in the cutting seedling breeding process; the water required for growth is sufficiently given, but the humidity is not too high; the air temperature change is observed at any time, so that the seedling fast breeds and roots.

Description

technical field [0001] The invention relates to the field of blueberry planting, in particular to a blueberry seed selection and breeding method. Background technique [0002] Blueberry is an emerging health-care berry. Blueberry fruit is rich in natural pigments and natural antioxidants. It also includes vitamin E, vitamin A, vitamin B, SOD, protein, fat and other special ingredients that are rare in other fruits. Its health effects are summarized It mainly has the following aspects: (1) it has functions such as preventing brain nerve aging, strengthening the heart, softening blood vessels, and enhancing human body immunity; (2) the anthocyanins in blueberry fruit have a good health care effect on the eyes and can relieve Eye fatigue and improve night vision; (3) has a good effect on eliminating inflammation in the body, especially for urinary tract infection and chronic nephritis; (4) has anti-cancer effect. It can be seen that blueberry is not only a delicious fruit, but...

[0003] However, the growth of blueberries has high requirements on the ecological environment, especially the requirements on soil conditions are unique, because its root system needs acidic environmental conditions, so not only the soil pH is required to be between 4.0 and 5.5, but also the soil is required to be moist. , high organic matter content and good ventilation, which restricts the commercial and industrial cultivation of blueberries and the reproduction of blueberry seedlings, resulting in the slow development of blueberry planting
