Podocarpus macrophyllus seedling cultivation method

Abstract

The invention discloses a podocarpus macrophyllus seedling cultivation method. The method comprises the following steps: S1, selecting to perform in spring or autumn; s2, collecting cutting slips, selecting and collecting semi-lignified lateral branches which grow robustly and germinate in the current year or are biennial, and disinfecting the lateral branches for later use; s3, branch treatment: quickly dipping the podocarpus macrophyllus lateral branches collected in S2 with a rooting agent solution for 5-10 seconds; s4, cutting of the cutting slips is carried out, branches 5 mm above leaves of the cutting slips selected in the S2 are cut off, and the cutting slips branches at the oblique cutting positions are 40-45 degrees; s5, seedbed cutting; s6, cutting. The method has the advantages that the podocarpus macrophyllus is convenient to move in the cuttage process, rapid propagation is facilitated, the seedbed is disinfected specially, so that microorganisms are not easy to dip and damage plant cutting slips, the water permeability and the air permeability are good, and seedlings cannot suffocate due to excessive moisture; particularly, the air humidity can be stabilized at 85% or above, so that the cutting slips grow in a suitable growth environment.

Description

technical field [0001] The invention relates to the technical field of pine tree cultivation, in particular to a method for cultivating Podocarpus seedlings. Background technique [0002] Podocarpus pine has lush and green branches in four seasons and has a kind of extraordinary temperament. If it can be tied and shaped, it will look even more beautiful. In addition, podocarpus has deep cultural connotations, and is even regarded as a symbol of wealth. However, Podocarpus is very precious. With the random digging of people, the resources of Podocarpus become more scarce, and it is already a national protected plant; [0003] Podocarpus is an evergreen tree; the leaves are spiral and alternate, strip-lanceolate, apex pointed, base narrowed into petiole-shaped, middle ribs on both sides raised, surface dark green, back yellow-green, flowers bisexual, male cones spike-shaped, often 3-5 in clusters in leaf axils; female cones are generally solitary in leaf axils, with stalks; f...

Problems solved by technology

[0004] As the city's demand for greening is increasing, the area of ​​greening is gradually expanding. Podocarpus plays an important role in landscaping, and it is easy to cultivate and manage. Therefore, in order to adapt to the development and needs of society, it is necessary to increase To understand Podocarpus pine, to optimize the cultivation technology of Podocarpus pine, seed breeding is one of the main ways of cultivating Podocarpus pine, but the seed oil of Podocarpus pine is high, which will inhibit the germination of seeds, and at the same time, the roots will develop after transplanting. Sluggish, growing way is slower, after transplanting and surviving, the growing way of Podocarpus pine is not luxuriant, grows dwarfly, and leaves are easy to wither and turn yellow;
