Embodiment 1

[0042] A method for branch propagation of Adiantum lotus leaf, comprising the following steps:

[0043] 1.1 Experimental materials: Select plants that grow robustly in the greenhouse and have full roots in pots as ramet materials.

[0044] 1.2 Time for ramets: In the early stage of new bud germination, ramets are carried out in conjunction with changing pots.

[0045] 1.3 Selection and treatment of substrates and pots: the substrates used in step S2 are divided into mixed substrate I and mixed substrate II, which respectively include the following components in parts by weight, mixed substrate I: 300 parts of river sand, 100 parts of sawdust ; Mixed substrate II: 300 parts of peat, 100 parts of coal cinder, 50 parts of river sand, and 100 parts of cake fertilizer residue. Spray the substrate with a mixed solution of potassium permanganate and cypermethrin 500-800 times each in fine weather and stir evenly, seal it with a film and sterilize it in the sun for 2 days, and open i...

Embodiment 2

[0072] 1.5 In the propagule treatment step: when transplanting to 130 pots, put 2-3cm thick crushed and fermented peanut shells and peat mass ratio of 1:1 substrate at the bottom, and then add 20-30 grains of American Austrian green manure, the total weight Be 3-5g, other and embodiment 1 are placed on the P in greenhouse shed 3 The groups were treated the same, and the results are shown in Table 6.

[0073] Table 6. Effects of basal fertilizers on the reproduction of Adiantum lotus leaf ramets

[0074]

[0075] It can be seen from Table 6 that when the pots were moved to 130 pots, the number of seedlings increased significantly, and the leaves were bright and large after adding peanut shells and American Austrian green manure. After the peanut shells are fermented, they are placed under the pot soil, which can be used as a water filter layer, so that they will not cause rotten roots to die due to water accumulation in the pot during later maintenance, and the substances r...

Abstract

The invention relates to a division propagation method of adiantum reniforme, and belongs to the technical field of forest tree propagation. Robust and luxuriant plants are taken as materials, the transplanting survival rate of propagules is effectively increased and the cultivation time is shortened with different treatment methods of the propagules before transplanting and management methods after transplanting. With adoption of the division propagation technology of adiantum reniforme for cultivation, the transplanting survival rate is high, seedlings grow fast, the production cost can be reduced, and the method has great significance for protection of rare and endangered species in China.

Description

technical field [0001] The invention relates to the technical field of tree breeding, in particular to a method for branch propagation of Adiantum lotus leaf. Background technique [0002] Adiantum lotus leaf, also known as lotus leaf money grass and wire grass, is a unique species in China under the genus Adiantum in the family Adiantum. It is only distributed in the Three Gorges of the Yangtze River in my country, with an altitude of 80-430m. The rhizome of Adiantum lotus leaf is short and erect, with single leaves in clusters, kidney-shaped leaves, bright black petioles, small and chic for viewing; it also has important medicinal value for jaundice hepatitis, urinary system infection, otitis media, etc. The disease has a better curative effect. However, the natural reproductive ability of Adiantum lotus leaf is weak, and the number is scarce. After the construction of the Three Gorges Project, the original area below 175m above sea level will be submerged. In addition, ...
