Embodiment Construction

[0010] The present invention will be further described below:

[0011] The present invention comprises the following steps:

[0012] (1) Fertilization: Every spring, after the soil is thawed, excavate a strip ditch with a width of 40 cm and a depth of 30 cm in the north-south direction of the tree body for fertilization; Centimeter deep strip ditch, fertilize, and then fill up the fertilization ditch to ensure the safe wintering of the hazel root system;

[0013] (2) Root-cutting treatment: From the third year after the hazel tree is planted, root-cutting will be carried out 3 times a year to guide the main root to extend deep into the soil. The specific method is: the first root-cutting treatment around May 20, and wait until the tree leaves , at a distance of 40-50 cm from the horizontal position of the main pole, dig a ring-shaped ditch with a depth of 40 cm to prevent the root system from growing horizontally, and at the same time loosen the soil and fertilize to induce t...

Abstract

The invention discloses a root cutting method for promoting stable growth of sandy-area filbert. The root cutting method includes the steps that on May 20th about, primary root cutting treatment is carried out, when leaves of a tree body are expanded, an annular furrow with the depth of 40 cm is dug at the portion 40 cm to 50 cm away from the horizontal position of a main rod, a root system is stopped to grow in the horizontal direction, soil loosening and fertilizer applying are simultaneously carried out, and the root system is induced to extend towards the soil depth; on June 20th about, secondary root cutting treatment is carried out with the same method, the depth is 50 cm about, and soil loosening and fertilizer applying are simultaneously carried out; on July 20th about, tertiary root cutting treatment is carried out with the same method, and the depth is 60 cm about. Compared with the prior art, the innovative scientific principles are adopted, the resistance such as drought resistance and cold resistance of the filbert is greatly improved, the space range when the filbert absorbs soil moisture is widened, healthy growth when the filbert is cultivated in sandy areas is promoted, the fruiting period is shortened, economic benefits are improved, and the high-quality and high-yield aim is achieved.

Description

technical field [0001] The invention relates to the technical field of forestry cultivation, in particular to a root-cutting method for promoting the stable growth of hazel trees in sandy areas. Background technique [0002] Hazelnut (Corylus) is a deciduous shrub or small tree belonging to Betulaceae (Betulaceae). It is one of the four major nuts in the world and has the reputation of "the king of nuts". Hazelnut is a woody grain and woody oil tree species with high comprehensive utilization value and wide application. However, hazelnut belongs to shallow-rooted tree species, and its root system is mainly distributed in the surface soil layer within 5-40cm. It is not resistant to drought, which affects the root system to develop in depth, and also hinders soil loosening and fertilization. The Mu Us Sandy Area is dominated by sandy soil and sandy loam soil, and the water content of the topsoil is poor. Moreover, the atmospheric drought in the Mu Us Sandy Area is severe from...
