Embodiment Construction

[0018] 1. Complete the preparations for the following nursery facilities in early July. Seedling raising facilities: 180㎡ simple greenhouse (length 30m, width 6m), remove the plastic film, and only cover the sunshade net with a shading rate of 50%. Surround three seedbeds with a width of 1.5m, a length of 29m, and a height of 35cm with bricks; pulverize the sandy loam core soil developed by shale into sand with a particle size of less than 0.5cm, put it into the seedbed with a thickness of more than 30cm, pour water thoroughly, and cover Moisturizing film.

[0019] 2. In late July or early August, after the semi-lignified branches of wild beech mother trees with a tree age of 2 to 30 years (the branches have certain toughness and hardness, all of which are yellowish brown), in the early morning of cloudy or light rainy days, the crown of beech tree The branches with a thickness of 1 to 2 cm in the middle and upper parts are collected and placed in a cool place indoors. ...

Abstract

The invention relates to a field cutting seedling raising method of Zelkovaschneideriana semi-lignification twigs. The field cutting seedling raising method mainly comprises a cut slip pruning method, a hormone treatment method, a matrix using method and a nursery garden temperature and humidity managing method. By utilizing the field cutting seedling raising method to perform large-scale field cutting seedling raising of the ZelkovaSchneideriana, cut slips and matrixes are sufficient, cost is low, final-period management is simple, the cutting survival rate can reach more than 86.0%, root systems of the cultivated biennial cutting seedlings are flourishing, and seedling using requirements of afforestation in autumn can be met.

Description

technical field [0001] The invention relates to a field cutting seedling raising method of beech twigs. Background technique [0002] Beech (( Zelkova. Schneideriana ), also known as beech tree, is a plant of the genus Beech with a wide distribution range in my country, and it is also a traditional precious furniture timber tree species. Difficulty in seed collection and low natural germination rate of seeds lead to difficulties in natural regeneration of beech trees, coupled with man-made destructive logging, so its wild resources are becoming increasingly scarce, and it has been listed as a second-class national key protected plant. With the in-depth research on the development and utilization of beech, it is found that beech has good medicinal value, and has good resistance and purification ability to air pollution. However, the difficulty in the propagation of beech seedlings has always been a bottleneck problem restricting the large-scale cultivation of this excellen...
