Embodiment 1

[0027] 1. Collection of cuttings: In June, the branches with a thickness of 0.3-0.4 cm that germinated outside the canopy and trunk of a strong adult tree in the previous year were harvested and then placed in a bucket with bottom water to prevent water loss.

[0028] 2. Cutting cuttings: Cut the cuttings into 6-8cm long cuttings, cut off the lower leaves and petioles, leave the upper 1-2 leaves, the upper cut is 0.5-1cm above the upper bud, and the lower cut is close to the petiole Cut flat at the birth place.

[0029] 3. Filling matrix of the hole tray: fill the hole tray with vermiculite, compact it slightly by hand, and place it under the awning (second-layer sunshade net). The tray is an ordinary plastic seedling tray with a specification of 50 holes and a hole size of 50mm*50mm*100mm.

[0030] 4. Cutting operation: Soak 2cm of the base of the cuttings in the 0.4%-0.6% solution of "Biaodian 3721 Drug" (online purchase active ingredient content: 95%) for 1.5-2.5 hours, an...

[0033] 1. Collection of cuttings: In June, the branches with a thickness of 0.3-0.4 cm that germinated outside the canopy and trunk of a strong adult tree in the previous year were harvested and then placed in a bucket with bottom water to prevent water loss.

[0034] 2. Cutting cuttings: Cut the cuttings into 6-8cm long cuttings, cut off the lower leaves and petioles, leave the upper 1-2 leaves, the upper cut is 0.5-1cm above the upper bud, and the lower cut is close to the petiole Cut flat at the birth place.

[0035] 3. Filling matrix of the hole tray: fill the hole tray with vermiculite, compact it slightly by hand, and place it under the awning (second-layer sunshade net). The tray is an ordinary plastic seedling tray with a specification of 50 holes and a hole size of 50mm*50mm*100mm.

[0036] 4. Cutting operation: Soak 2cm of the base of the cuttings in the 0.4%-0.6% solution of "Biaodian 3721" for 1.5-2.5 hours, then insert it straight into the vermiculite matrix to a...

Abstract

The invention discloses an ilex purpurea cell tray hardwood cutting seedling-raising method. The method comprises the following steps of 1, cutting collection: branches which grow last year at the trunk and the external portion of a strong adult crown and of which the thickness is 0.3-0.4 cm are collected, and after the branches are collected, water retention is conducted on the branches, 2, cutting slip cutting: cuttings are cut into cutting slips of which the length is 6-8 cm, lower portion leaves and leaf stalks are cut off, 1-2 leaves at the upper portion remain, upper pruning wound is 0.5-1 cm higher than an upper sprout, and the lower pruning wound is transversally cut close to the position where the leaf stalks insert, 3, vermiculite base material cell tray filling, 4, cuttage operation: 2 cm of cutting base is soaked in a rooting agent solution and is vertically inserted into a vermiculite base material, after the cutting base is inserted into the base material, the base material around the cottage base is pinched and compressed, and after the insertion, the cutting base is watered thoroughly, 5, management after the cottage: the cutting base is watered twice every day, the cutting base is kept wet, the base material flushed away is added in time when the cutting base is watered, and after the cutting base roots, the cutting base is transplanted. Compared with the prior art, according to the ilex purpurea cell tray hardwood cutting seedling-raising method, the difficulty that ilex purpurea cannot reproduce by using hardwood to raise cutting seedling can be solved, and the average rooting number, the survival rate and preserving rate of the ilex purpurea are significantly increased.

Description

technical field [0001] The invention relates to a method for growing seedlings of holly holly with plugs of hard branches, belonging to the technical field of cutting seedlings. Background technique [0002] Ilex corallina Franch. belongs to the Ilex family, the genus Ilex, and the subgenus Ilex. It is mainly distributed in the Yangtze River Basin. It is an evergreen tree with red fruit. It stays on the tree for a long time, generally extending from October of the current year to April to May of the next year. Therefore, it has high ornamental value when used in gardens. [0003] The hard branch cutting propagation seedlings of holly holly have the advantages of fast growth, strong resistance and high seedling preservation rate. Often take tender branch cuttings (survival rate 70%) in the plum rain season in production at present, hard branch cuttings are often not easy to take root and cause survival rate and preservation rate to be low and are not used. Contents of the ...
