Grafting seedling method for improving adaptability of blueberries to soil with high pH value

Abstract

The invention belongs to the technical field of vegetative propagation of high-quality high-resistance nursery stocks of novel and special fruit tree blueberries, and relates to a grafting seedling method for improving the adaptability of blueberries to soil with a high pH value. The method comprises the following steps: constructing a cutting orchard, cultivating stock seedlings, cultivating grafting seedlings, moving the seedlings outside the cutting orchard, and constructing a blueberry garden. According to the method, vaccinium bracteatum in the Yangtze River regions of China is adopted to be grafted with a south highbush blueberry variety, namely sharpblue, the stock is easily available, and is easy to breed, the grafting method is simple and convenient, the survival rate is high, respective excellent biological characters of stock tree varieties and scion varieties are combined in the grafted tree, after being planted, the blueberry tree grows strongly and healthily when being compared with cuttage blueberry trees of the same age, the blueberry tree has the advantages that the early fruiting character and the yielding ability of the plants, the flavor of the fruits, the nutrition and the healthcare property of fruits are also remarkably improved compared with the cuttage blueberry trees, remarkable advantages and potentials are shown up, and the grafting seedling method is worthy of popularization in blueberry cultivation practice in China.

Description

technical field [0001] The invention belongs to the technical field of high-quality and high-resistance asexual propagation of blueberry (Vaccinium spp.) high-quality and high-resistance seedlings of emerging characteristic fruit trees, and in particular relates to a method of grafting and improving "Sharpblue" (Sharpblue) blueberry to high A technical approach to pH soil adaptation. Background technique [0002] The root system of blueberry fruit trees is slender, the tap root is not obvious, the root hairs are scarce, very underdeveloped, and the roots are often intertwined, and the distribution in the soil is shallow and the extension is very narrow. The physical and chemical properties of the soil have far greater influence on its growth and development than other Fruit tree species. In particular, blueberries like acidic and strongly acidic soils, and the suitable soil pH value is 3.8 to 5.0. Countries around the world, including China, almost without exception need to...
