Problems solved by technology

Existing red alder vegetative propagation mostly adopts twig cutting propagation technology, generally adopts GGR, IAA, ABT1 and other hormone treatment before cutting, but the rooting effect is not good, and branch cutting is mostly carried out in summer and autumn, the light intensity, moisture, Difficult temperature management and low production efficiency
There is no complete report on hardwood cutting technology

Embodiment

[0018] Example: A method for raising seedlings by hardwood cuttings of red alder, using 1-2-year-old young forest branches of young forests as cuttings:

[0019] 1. Matrix screening: choose perlite as its rooting matrix;

[0020] 2. Production of cutting bed: use the existing perlite cutting pool, the thickness of perlite is about 20cm;

[0021] 3. Substrate treatment: 24 hours before cutting, use 1000 times of carbendazim or other sterilizing agents to spray for sterilization;

[0022] 4. Cutting time: before the middle of March, especially before the red alder branches germinate;

[0023] 5. Cutting cuttings: Make full use of the pruned branches of red alder, select the ones that are free from diseases and insect pests, strong and full of buds. At the cutting site, use the method of cutting while cutting. The length of the cuttings is about 15cm. 2~3cm, the bottom incision is obliquely cut, about 1~1.5cm away from the bud, the incision is smooth without tearing;

Abstract

The invention discloses a method for raising seedlings of red alder through hard wood cutting. The method includes the following steps that trimmed branches are cut into cutting slips with the length being about 15 cm, one third to one second of the lower ends of the cutting slips are inserted into a perlite cutting pool, density control is conducted, daily management is conducted, and outplanting and transplanting are conducted. According to the method, the branches to be trimmed are fully used, the breeding cost is reduced, and the purpose of rapid breeding is achieved; the cutting rooting rate of the red alder is increased by effectively using season advantages, the breeding speed of the red alder is increased, and the transplanting survival rate is high; a cutting medium is simple, the production cost is low, no rooting hormone is used, the cutting rooting process is simple, operation is simple, cutting steps and the management process are simplified, and the management cost is reduced.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a cutting method of red alder. Background technique [0002] At present, the propagation methods of red alder are mainly seed propagation and cutting propagation. Seed germination rate is high, but seedling rate is low. There are two types of cutting propagation: hard branch cuttings and soft branch cuttings. Existing red alder vegetative propagation mostly adopts twig cutting propagation technology, generally adopts GGR, IAA, ABT1 and other hormone treatment before cutting, but the rooting effect is not good, and branch cutting is mostly carried out in summer and autumn, the light intensity, moisture, It is difficult to manage temperature and so on, and the production efficiency is low. There is no complete report on hardwood cutting technology. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to overcome the deficiencies in...
