Embodiment Construction

[0014] 1. Overview of the implementation site

[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] 2. Soil 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...

Abstract

The invention discloses a barren hill afforestation method for pine cuttage seedlings. The method is characterized by comprising the following steps: carrying out a land preparation method: completely removing weeds from hillside fields of a barren hill to be afforested in August to September, then, deeply ploughing the fields to the depth over 50cm, carrying out leveling so as to prepare platforms with the width of 1.5-2.0m, and digging planting holes in accordance with that the row spacing is 1.5m and the plant spacing is 1.0m, wherein the size of each hole is that the length is 50cm, the width is 50cm, and the depth is 40cm; carrying out a base fertilizer application method: firstly carrying out base fertilizer application before nursery-grown plant transplanting, applying 1kg of formulated humus soil and 0.25kg of compounded fertilizer to each hole, and covering each hole with soil with the thickness of 5-7cm; and carrying out a cuttage seedling transplantation method: taking out just-defoliated biennial cuttage seedlings from seedling beds in October to November, trimming off most of branches and tips, then, only reserving one trunk with the height of 20cm for each cuttage seedling, soaking the cuttage seedlings with a 20mg / L GGR rooting agent aqueous solution for 5 hours, carrying out field planting on the hill in a manner that each trunk is exposed the ground by 5cm, and thoroughly irrigating the planted cuttage seedlings with rooting water.

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...
