Embodiment 1

[0033] In 2015, a 750m planting area of ​​the present invention was built 2(length 75m, width 10m), in the planting area: in the autumn of one year before planting, after deep plowing of 25cm, rake and apply 1.5 tons of organic fertilizer; set up a raised bed, the height of the bed is 30cm, the width of the seedbed is 1.5m, and the width of the footpath is 50cm between the beds. The seedbed is 75m long. In the spring of the planting year, Nanjing lindens (250 plants) with an average seedling height of 1.0-1.5cm and an average ground diameter of 0.8cm-1cm were selected, planted in a narrow plant-wide row of 1.5m×2.0m, and rooted with rooting powder mud; Between the column, pull the wire rope, plant the bamboo pole while planting the seedlings in the planting hole; spray the closed herbicide acetochlor 70ml (diluted to 0.1%) after planting, and cover with black plastic film. Before germination, keep the full buds near the top by topping; after germination, even remove the roots...

Abstract

The invention discloses a tilia miqueliana high-quality full-crown engineering seedling cultivation method which comprises the following steps: pouring cement columns at two ends of a planting row, pulling steel wire ropes between the columns, and fixing the steel wire ropes at the tops of the columns; planting seedlings in spring, erecting bamboo poles beside planting holes, fixing the tops of the bamboo poles on the steel wire ropes, selecting one to two-year-old tilia miqueliana seedling bare-rooted seedlings, adding mud into a rooting powder aqueous solution for root dipping, performing earthing and treading, and positioning the seedlings and the steel wire ropes on two sides of the bamboo poles; thoroughly watering rooting water for two consecutive days after field planting; binding new shoots on the bamboo poles every 15 cm in the growing season, and removing terminal buds on side branches larger than 20 cm; removing lateral branches on the lower portion of the trunk in autumn, and trimming lateral branches on the upper portion according to the principle of controlling strength and strengthening weakness. According to the method, an existing tilia miqueliana engineering seedling cultivation technology is improved, and the problems that tilia miqueliana is poor in uprightness in the seedling stage, poor in finished seedling trunk shape and insufficient in crown are solved;and the method is simple and feasible in steps, and low in cost, can be easily accepted by producers and is beneficial to production, popularization and application.

Description

technical field [0001] The invention relates to a method for cultivating Nanjing linden fine-quality full-crown engineering seedlings, belonging to the technical field of seedling planting. Background technique [0002] Nanjing linden is a unique native tree species in my country. It is a tall tree with a tree height of up to 20 meters. It is an important economic tree species integrating timber, fiber, medicine, honey source, ornamental and cultural inheritance. The natural distribution range of Nanjing Linden extends from Suzhou, Anhui in the north, Taizhou in Zhejiang in the south, Zhoushan in Zhejiang in the east, and Huangshan in Anhui in the west, and has been successfully introduced and planted in Beijing and Northeast China. Broad application value and market prospect. Nanjing linden tree has a straight and round trunk, a wide and dense crown, rich fragrance of flowers, and peculiar bracts. It is easy to trim and can be used as an excellent landscaping tree species....
