Large zelkova schneideriana seedling cultivation method

Abstract

The invention discloses a large zelkova schneideriana seedling cultivation method. The method includes steps: (1) nursery land selection; (2) land preparation and bedding; (3) soil disinfection; (4) base fertilizer applying; (5) transplanting seedling selection; (6) transplanting time selection; (7) transplanting; (8) density adjustment; (9) transplanting root cultivation; (10) stem form cultivation; (11) pruning; (12) water and fertilizer management; (13) intertillage and weeding; (14) pest control; (15) outputting. According to the method, large landscaping zelkova schneideriana seedlings which are larger than 5cm in diameter at breast height, straight thoroughly, round completely, well developed in root system, robust and flourishing in growth are cultivated. In a large seedling cultivation process, by initial-density continuous pruning, transplanting, adjusting, operating and management, large landscaping zelkova schneideriana seedlings in different sizes are cultivated batch by batch and stage by stage to meet zelkova schneideriana fast-growing high-yield plantation and urban landscaping requirements, woodland productivity and output capacity are increased, and economical, social and ecological benefits are achieved.

Description

technical field [0001] The invention relates to a method for cultivating large beech seedlings. Background technique [0002] Beech is a national second-level key protected tree species, which has good economic and ecological value. However, the production cycle of small beech seedlings in the current cultivation of beech is long, and the survival rate of planting cannot reach 100%. The growth of trees is not uniform, and the quality of forest stands is not high, so the productivity and output rate of forest land are low, and it is difficult to achieve fast growth and high yield and rapid formation of landscape effects. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for cultivating beech tree seedlings. The beech tree greening seedlings cultivated by the method can meet the needs of beech tree fast-growing and high-yield afforestation and urban landscaping, so as to improve woodland productivity and output r...
