Problems solved by technology
At present, the demand for seedlings is huge, and it is difficult to meet the production needs by natural root division and layering propagation
The traditional method of propagating A. glabrata is root cuttings and hard branch cuttings. Root cuttings need to excavate the original plantation, requiring a lot of manpower and material resources, and destroying the garden. The survival rate of hard branch cuttings is very low, and root cuttings and hard branch cuttings can only be carried out once a year. Irregularity, poor growth, longer out-of-the-nursery period, slow reproduction speed, and increased reproduction costs

Embodiment Construction
[0015] The technical solutions of the present invention will be further described below according to specific embodiments.
[0016] A method for cutting propagation of eucalyptus glabrata green branches is realized through the following steps:
[0017] 1) Management of picking orchard. Select land with deep soil and fertile soil to establish ear-picking gardens, manage fertilizer and water regularly, and prevent and control diseases and insect pests;
[0018] 2) Preparation and management before cutting. Takakuro is used in ordinary plastic greenhouses, with a height of 15-20cm and a width of 120cm, and a micro-spraying system in the middle of the furrow; according to the volume ratio of 3:2:4:1, crushed perlite, rice bran, peat, and tobacco powder are used as substrates , add 2.5kg neem powder per cubic meter, mix evenly to make a non-woven matrix container, the non-woven matrix container has a diameter of 4-5cm and a height of 7-8cm, and is placed on the furrow surface;

Abstract
The invention discloses a green branch cuttage propagation method for broussonetia papyrifera. The method includes the steps of cutting orchard management, pre-cuttage preparation management, cutting collection, cuttage branch preparation, cuttage, maintenance management and the like. Every time after cuttage in one bed is completed, water is sprayed immediately, a small shed is built on the bed, the matrix humidity is kept at 80% or so, and the temperature is kept at 28-35 DEG C; a 75% shading net is adopted for shading in July to October, sterilization is carried out once every 7-10 days, callus tissue is formed at cutting bases in 7-10 days, 5-7 new roots come up in 15-20 days, axillary buds emerge, the matrix humidity and the air humidity are controlled, thin film on the small sheds is removed, step-by-step seedling hardening is carried out, and broussonetia papyrifera seedlings can come up in 30-35 days. Compared with the prior art, the method effectively solves the problems of shortage and no source of seedlings, and has the advantages that cuttage rooting is fast, the rooting rate is high, the seedling formation cycle is short, propagation is fast, seedlings can come out of a nursery easily, seedlings are uniform, the cost is low, and the planting survival rate is high.
Description
technical field [0001] The invention relates to the technical field of horticultural cultivation, in particular to a method for cutting and propagating green branches of eucalyptus glabra. Background technique [0002] The fast-growing broad-leaved wood species, deciduous tree, belongs to Moraceae and Structura genus. This tree species can not only be used as greening and soil and water conservation tree species, but also has high economic value: it is easy to cultivate. Harvesting is a tree species with an ultra-short rotation period. The harvesting cycle is 3-4 months. It can germinate after felling. It can be planted in one year and harvested year after year. It has low production cost and fast capital turnover, which is conducive to the promotion of planting by farmers. It has strong adaptability, drought resistance and thin ridges, grows well in hills and river beaches, and is tolerant to salt and alkali (Moraceae plants themselves have a salt resistance of up to 3‰).
