Embodiment 1

[0022] Torreya cuttings mainly include the following steps:

[0023] 1) Transplantation preparation: The cutting site is located in the greenhouse of the State Key Laboratory of Subtropical Forest Cultivation of Zhejiang Agriculture and Forestry University in Lin'an City, Zhejiang Province (29°56'-30°23' north latitude, 118°51'-119°52' east longitude). A 1.8m high iron frame is built on the cutting bed of the greenhouse, a sunshade net with a light transmittance of about 50% is laid, and automatic spraying equipment is equipped. The slotting bed is composed of 0.3m(W)×1.1m(L)×0.2m(H) foam grooves, fixed with iron wires, with drainage grooves and drainage holes at the bottom. Spray 0.03% potassium permanganate solution on the surface of the foam tank and cover it with a film and seal it for disinfection for 14 days;

[0024] 2) Cutting substrate: the substrate is peat (0-10mm, Pindstrup, Denmark), vermiculite (5-8mm), perlite (2-4mm), according to peat: perlite: vermiculite = ...

[0034] 1 Overview of the test site

[0035] The test site is located in the greenhouse and laboratory of the State Key Laboratory of Subtropical Forest Cultivation of Zhejiang A&F University in Lin'an City, Zhejiang Province (29°56'-30°23' north latitude, 118°51'-119°52' east longitude). A 1.8m high iron frame is built on the cutting bed of the greenhouse, a sunshade net with a light transmittance of about 50% is laid, and automatic spraying equipment is equipped.

[0036] 2 Materials and methods

[0037] 2.1 Test materials and treatment

[0038] In the morning or evening, at the Torreya nurturing base on the campus of Zhejiang A&F University, the branches that grew vigorously in the current year without pests and mechanical damage (hereinafter referred to as ordinary branches) were collected from 10-12 year old Torreya female plants. The processing of the cuttings should be completed within 2 hours after collection as far as possible, and the cuttings should be wrapped with...

Abstract

The invention discloses a Chinese torreya cutting propagation method and belongs to the technical field of vegetative propagation of plants. The method is characterized by mainly comprising the following steps: 1, slotting machine preparation; 2, cutting slip collection; 3, cutting slip treatment and cutting; 4, cutting later-period management; 5, transplanting; 6, transplanting later-period management. By means of the technical scheme of the method, the cutting rooting rate of Chinese torreya reaches 96.67%, the number of lateral roots is large, and the root system is robust; statistics is conducted after 14 months passes since cutting seedlings are transplanted, the survival rate reaches 91.67%, the shoot growing amount is 4.53 cm, the root system is robust, the problems that rooting is not easy to achieve for Chinese torreya cutting, and the rooting cycle is long are solved, the method is simple, easy to operate and low in cost, effective and rapid vegetative propagation of Chinese torreya can be achieved, and great practical significance is achieved for accelerating popularization of excellent Chinese torreya genotypes, promoting Chinese torreya nursing, popularizing afforestation and conducting reasonable resource utilization.

Description

technical field [0001] The invention belongs to the technical field of plant asexual propagation, in particular to a method for cutting and propagating Torreya torreya. Background technique [0002] Torreya ( Torreya grandis ‘Merrillii’) belongs to the genus Torreya (Taxaceae) Torreya Arn.) Torreya ( Torreya grandis Fort. ex Lindl) is a rare dried fruit unique to my country, with scarce resources and a long life cycle. It is a multi-purpose high-quality economic tree for fruit collection, oil use, medicine, wood, greening and ornamental, and ecology. species group. Torreya torreya seeds have very high nutritional value, rich in protein and various trace elements; processed into dried fruit, they can be used as delicious food, and they are also valuable Chinese medicinal materials. In addition, the bark of Torreya torreya can be extracted for industrial use. Its wood has straight grain and moderate hardness. It is an excellent material for shipbuilding, construction, sl...
