Blueberry cutting seedling method convenient to root

Abstract

The present invention discloses a blueberry cutting seedling method, and relates to the technical field of blueberry plantation. The method comprises a first step of seedbed establishment, 13-16 cm thick coarse coal slags being laid at a bottom layer of the seedbed, 8-11 cm coarse sand is laid at a middle layer, and 13-16 cm fine river sand being laid at an upper layer; a second step of cutting collecting and processing, selecting strong current-year semi-lignified forky green branches from seed trees as cuttings, trimming the forky branches to be L-shaped, a lower part of each branch being 8-10 cm in cutting length with tender shoots being removed while an upper part being 6-8 cm in cutting length with 1-2 tender shoots being retained, removing the lower part, soaking a root part of the lower part by ABT No.1 rooting powder of 400 mg / kg, and carrying out cuttage after 30 seconds of soaking; a third step of cuttage and seedbed management, cuttage depth being 4-5 cm, a lower part of each cutting being fully buried into the soil while an upper part is perpendicular to the ground, with only one apical bud being exposed; a fourth step of antiseptic treatment; and a fifth step of transplantation, nursery-grown plants generally living through the winter on the seedbed. The method provided by the present invention is standard in management, high in cutting seedling survival rate and fast in root growth.

Description

Technical field: [0001] The invention relates to the technical field of blueberry planting, in particular to a method for growing blueberry cutting seedlings convenient for rooting. Background technique: [0002] Blueberry is a low shrub, wild with short legs, small particles, and rich in anthocyanins; the second type is artificially cultivated blueberries, which can grow to 240cm in height, with larger fruits and plump flesh, which improves the taste of wild blueberries and enhances the taste of wild blueberries. Improve the body's absorption of anthocyanins. There are more than 400 species of Vaccinium distributed all over the world. It originates in and is mainly produced in the United States and is also known as American blueberry. Wild blueberries in my country are mainly produced in the forest areas of Changbai Mountain, Daxinganling and Xiaoxinganling. It has only been successfully domesticated and cultivated in recent years. There are many ways to reproduce bluebe...

Problems solved by technology

The existing cutting seedling management is not standardized, the cuttings are all trimmed into straight shapes, and the rooting of the cuttings has a certain depth requirement, the parts that are too shallow or too deep have little or no rooting, and the blueberry branches have more roots The part is located at 4-5cm below the soil, and there are very few cuttings at this depth, so the rooting probability and speed will be relatively slow, so the survival rate of cutting seedlings is low, especially the rooting survival rate of some varieties when cutting Very low, the rooting speed is slow, and the time span required for planting is long
