Twig cutting method for ilex crenata golden gem

Abstract

The invention discloses a twig cutting method for an ilex crenata golden gem. Local yellow-core soil serves as a cutting matrix. A rooting agent is a water solution prepared by NAA and water of which are ratio is 1:1000 to 2000. Cutting is conducted in summer and semi-lignified branches of the upper portion of a tree crown without diseases in the current year are selected to serve as cutting slips. After being dipped in the prepared rooting agent for one hour, the cutting slips are inserted into the matrix. After being inserted into the matrix, the cutting slips are thoroughly watered. The cutting slips are placed in a greenhouse covered with a sunshade net and maintenance and management are conducted. According to the twig cutting method for the ilex crenata golden gem, the cutting period is short and the survival rate is high and reaches over 95%.

Description

technical field

[0001] The invention relates to the field of plant asexual propagation, in particular to a method for cutting twigs of holly holly. Background technique

[0002] Golden leaf tortoiseshell holly likes a warm, humid and sunny environment. It is semi-shade tolerant, medium growth rate, bright and pleasing to the eye, strong budding and branching ability, resistant to pruning, fast forming, and strong resistance to diseases and insect pests. The cutting method is a common propagation method of Ilex japonica, but the existing propagation method has a low survival rate. Contents of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method for cutting twigs of Ilex japonica.

[0004] Technical scheme: in order to achieve the above object, a kind of twig cutting method of golden-leaf tortoiseshell holly provided by the invention comprises the following steps:

Embodiment 1

[0013] A kind of twig cutting method of golden-leaf tortoiseshell holly, comprising the following steps:

[0014] 1) Preparation of seedbed and cutting substrate: choose a seedbed with a width of 1 meter and a length of 15 meters in the greenhouse, and cover it with soil;

[0015] 2) Prepare the cuttings: choose a healthy and pest-free golden-leaf tortoiseshell holly mother tree, take the semi-lignified branches that were born in the year, cut them into one leaf and two buds, and the length is 3-4 cm, which is the best cutting;

[0016] 3) Rooting agent preparation: mix naphthaleneacetic acid (NAA) with water at a ratio of 1:1000 to prepare rooting agent, and set aside;

[0017] 4) After soaking the cuttings in the prepared rooting agent for 1 hour, cut them in the seedbed. The density is based on the fact that the leaves do not overlap after cutting;

[0018] 5) Management after cuttings: After cuttings, water the substrate thoroughly, cover the greenhouse with sunshade nets...
