Embodiment Construction

[0014] Implementation site overview

[0015] 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°.

[0016] land preparation

[0017] 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 method for achieving waste mountain afforestation by using pine tree cutting seedlings. The method for achieving waste mountain afforestation by using the pine tree cutting seedlings is characterized by comprising the following steps that 1, a soil preparation method is adopted and comprises the steps that weeds of sloping fields of an afforestation waste mountain are removed, then deep ploughing for depth of more than 50 cm and leveling are performed to form platforms with the 1.5 m-2.0 m width in August or September, planting holes are dug according to the requirement for line spacing 1.5 m * plant spacing 1.0 m, the length of the holes is 50 cm, the width of the holes is 50 cm, and the depth of the holes is 40 cm; 2, a base fertilizer applying method is adopted and comprises the steps that a base fertilizer is firstly applied before nursery stock transplantation, 1 kg formula humus soil and 0.25 kg compound fertilizer are applied in each hole, and 5-7 cm earthing is performed; 3, a cutting seedling transplantation method is adopted and comprises the steps that defoliated biennial cutting seedlings are taken out of a seed bed, most of branch tips are cut off, then only 20 cm one-branch trunks are left, a 20 mg.L-1 GGR rooting reagent water solution is used for soaking the trunks for 5 hours, field planting is performed in the mountain, the trunks are exposed out of the ground for 5 cm, and thorough watering after planting is performed in October or November.

Description

technical field [0001] The invention relates to a method for afforestation of barren hills by cutting seedlings of pine trees. Background technique [0002] Afforestation techniques of pine seedlings have been preliminarily studied. Most studies believe that the best afforestation season for seedlings is 2-3 months after the beginning of spring; the best initial planting density of saplings is 2m×2m or 2m×3m; site conditions have a greater impact on the growth of pine trees, and site conditions are good For the land type, pine trees grow faster, and sandy loam soil is most suitable for the growth of pine trees. The research on base fertilizer treatment has not been reported. There is no report on the research on the afforestation technology of pine cuttings. [0003] Difficulty in the propagation of pine seedlings has always been a bottleneck problem restricting the large-scale cultivation of this fine timber resource. With the breakthrough of pine cutting seedling raisi...
