Tilia miqueliana high-quality full-crown engineering seedling cultivation method

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.
