Embodiment Construction

[0015] Implementation site overview

[0016] The geographic coordinates of the test site are E106°50′14.73″, N26°42′11.45″, located in the Maochong Formation Mountain Field, Pei’e Village, Shuitian Town, Wudang District, Guiyang City, 19 kilometers away from Guiyang City. The test site is an independent slope with an average altitude of 1080m and a slope of 35°.

[0017] land preparation

[0018] Divide the slope head into 3 site types: slope top (slope of about 5°, area of ​​1.5 mu, soil layer thickness <10cm, gravel content of more than 70%, deep plowing of 50cm for reclamation; slope land (slope of about 35°, area of ​​1.5 Mu, soil layer thickness 15-25cm, gravel content about 20%, uncultivated); platform (slope below 2°, area 1.5 mu, soil thickness 10-15cm, gravel content about 40%, deep plowing 50cm land reclamation ). Dig planting holes according to the specifications of 50cm (length) × 50cm (width) × 40cm (depth), the hole spacing is 1.5m (row spacing) × 1.0m (pla...

Abstract

The invention discloses a barren hill afforestation method of Zelkovaschneideriana cutting seedlings. The barren hill afforestation method mainly comprises a soil preparation method, a base fertilizer applying method and a seedling transplanting method. By utilizing the barren hill afforestation method to perform barren hill afforestation of the Zelkovaschneideriana cutting seedlings, under the site condition that the gravel content of a barren hill is 30%-70%, the survival rate of afforestation can reach 100%-95%, the annual growth of the plant height of plants can reach 100.93cm-84.00cm, the annual growth of the ground diameter can reach 0.79cm-0.67cm, and the annual growth of the branch length of single branches can reach 27.35cm-23.13cm. The method provides afforestation technology support for large-scale cultivating Zelkovaschneideriana commercial forest by means of abandoned barren mountains.

Description

technical field [0001] The invention relates to a method for afforestation of barren hills by beech tree cutting seedlings. Background technique [0002] Ulmaceae Beech ( Zelkova ) plants are one of the precious hard broad-leaved timber species in my country. my country is the center of natural distribution of beech plants, and there are big-leaved beech (( Z. Schneideriana ), Beech ( Z. serrata ) and Beech ( Z. sinica )3 species; Guizhou naturally distributes two species of Zeech and Zeech, among which Zeech has a wide distribution range. Difficulty in seed collection and low natural germination rate of seeds lead to difficulties in natural regeneration of beech trees, coupled with man-made destructive logging, so its wild resources are becoming increasingly scarce, and it has been listed as a second-class national key protected plant. With the in-depth research on the development and utilization of zelkova, it has been found that zelkova has good medicinal value...
