Problems solved by technology

This invention is a cuttage breeding method of Podocarpus pine. Selecting semi-lignified branches with heels can promote the rooting of cuttings more easily. By disinfecting the cuttings and treating them with auxin, and timely fertilizing, weeding, and insect removal, the growth rate of Podocarpus can be increased. The survival rate of cutting propagation, but picking a large number of strips will also cause great damage to the existing shape of Podocarpus podocarpus, seriously affecting the propagation process, far from meeting market demand

Embodiment 1

[0038] A method for cutting and breeding red-leaved Podocarpus pine leaves, comprising the steps of:

[0039] (1) Preparation before cutting seedlings

[0040] a. Substrate preparation: fully mix the volume ratio of peat soil: vermiculite: perlite = 1:1:1, fill it into a seedling tray, and place it on the seedbed in the shade greenhouse for standby;

[0041] b. Substrate disinfection: 1 day before cutting, use thiophanate-methyl 1000 times solution to water the substrate for disinfection and sterilization, and then cover it tightly with a film for later use;

[0042] (2) Selection of cutting leaves

[0043] a. Mother tree selection: choose the red-leaf Podocarpus pine that is free from pests and diseases and grows robustly; on the same plant, try to choose the middle and upper parts of the mother tree; on the same branch, try to choose the middle leaves, do not choose too old or too tender leaves; leaf selection Robust leaves without wormholes, yellow leaves, variegated leav...

Embodiment 2

[0059] All the other are identical with embodiment 1, and difference is: step matrix disinfection in the above-mentioned steps (1): 1.5 days before cutting, water matrix with potassium permanganate 1000 times of liquid and carry out disinfection and sterilization, then cover tightly with film for subsequent use; step (4) The compound method of rooting agent described in (4) is as follows, adopts naphthalene acetic acid rooting powder to add alcohol to dissolve, adds water dilution and is mixed with 300mg / L mass concentration rooting agent.

Embodiment 3

[0061] All the other are the same as in Example 1, the difference is: step matrix disinfection in the above-mentioned steps (1): 2 days before the cutting, water the matrix with 1000 times of liquid thiophanate-methyl to carry out disinfection and sterilization, then cover tightly with film for subsequent use; step (4) The compound method of rooting agent described in (4) is as follows, adopts naphthalene acetic acid rooting powder to add alcohol to dissolve, adds water dilution and is mixed with 400mg / L mass concentration rooting agent.

[0062] Select the seed of Podocarpus podocarpus as breeding female parent, as control group, with germination time, germination rate, average seedling height, seedling area, main root number, lateral root length and main root length as embodiment 1, embodiment 2, embodiment 3 and The control group test indicators, the results are as follows:

[0063]

[0064] As can be seen from the above table, the germination time and seedling area of ​...

Abstract

The invention discloses a red-leaf P .macrophyllus var .macrophyllus leaf cutting propagation method, and relates to the technical field of seedling propagation. The method includes the following steps of preparation before seedling raising by cutting, selection of cutting leaves, treatment of the cutting leaves, leaf cutting, management after cutting and fertilizer and water management. Red-leafP .macrophyllus var .macrophyllus leaves are adopted for cutting propagation, due to the fact that the sprouting capacity of red-leaf P .macrophyllus var .macrophyllus is high, the leaves are lanceolar in a strip-shaped mode, the leaves are tightly arranged, the mature leaves are 5-12 cm long and 0.5-1 cm wide, a large number of cutting leaves are available, the propagation bottleneck of existingred-leaf P .macrophyllus var .macrophyllus can be overcome, and the factory-like propagation process can be carried out within a short period.

Description

technical field [0001] The invention relates to the technical field of seedling breeding, in particular to a method for cutting and breeding red leaf podocarpus leaves. Background technique [0002] Podocarpus var.macrophyllus (P.macrophyllus var.macrophyllus) is an arbor species of the genus Podocarpus in the gymnosperm family Podocarpus family. It is mainly distributed in Jiangsu, Zhejiang, Fujian, Jiangxi, Guangdong and Guangxi in the south of the Yangtze River. Humid climate conditions, not resistant to severe cold, in the north can only be potted indoors to survive the winter. Podocarpus pine trees are elegant, with dense branches and leaves, and are resistant to pruning. They are suitable for trimming into various shapes, especially when the new leaves of podocarpus pine germinate in spring are red, and the clusters of buds are like blooming red flowers. It is magnificent and charming. Qingya is an excellent ornamental tree species for gardens, temples, courtyards, an...
