Factory cutting seedling raising method for pinus elliottii

Abstract

The invention discloses a factory cutting seedling raising method for pinus elliottii. The method comprises the steps of building a greenhouse, dressing cutting beds, preparing a matrix and seedling raising containers, placing the seedling raising containers, subjecting the cutting beds and the cutting matrix to sterilization and disinfection, scissoring and treating cutting slips, disinfecting the cutting slips, carrying out cutting, building low arched sheds and carrying out later-stage management, wherein the later-stage management comprises the steps of (1) sterilization, (2) water and fertilizer management and (3) light, humidity and temperature control. The method is characterized in that basal planes of the cutting beds are transparent, the cutting matrix is prepared from coco coir,peat, vermiculite and pearlite, the seedling raising containers are bottomless coverless cylindrical bodies, and the cutting slips are one-year-old semi-lignified tree shoots. The method has the advantages that the survival rate of cutting is high, the root system is developed, the cutting management is convenient, the labor intensity is low, the transportation of nursery-grown plants is portableduring afforestation, and the survival rate of afforestation is high due to lightweight-matrix-carrying transplanting; and excellent quality characteristics are maintained, so that the method is applicable to large-scale factory seedling raising, and the positive effect of meeting the requirements of man-made pinus elliottii forests on improved variety is achieved.

Description

technical field [0001] The invention relates to the technical field of pine seedling cultivation, in particular to the cutting and seedling raising technology of pine trees, in particular to a method for industrialized cutting and seedling raising of slash pine. Background technique [0002] Slash pine ( pinus elliottii ) is a fast-growing evergreen tree native to the warm and humid low-altitude areas of the southeastern United States. It is not only an excellent industrial timber species, but also one of the species with the highest rosin yield and the best quality among pine species. At present, the main way of raising slash pine seedlings in my country is to breed seedlings by sowing. The source of slash pine seeds mainly depends on the slash pine seed gardens established at home and abroad. There are problems such as difficult seed harvesting, high cost, and large differences in the quality of seedlings cultivated from seeds; and the output of seed gardens varies from ...

AI Technical Summary

Problems solved by technology

Therefore, it has the following disadvantages: 1. The quality of sand in the cutting substrate is heavy, it is inconvenient for afforestation and transportation, and the cost is high. The sawdust market source range is narrow, and it is inconvenient to obtain materials

2. For cuttings, 2-3 years old lignified branches are used as cuttings. The young degree of cuttings is low, rooting is difficult, and the survival rate of cuttings is low.

[0003] It is worth pointing out that although the above-mentioned method for cutting seedlings of pine trees can solve or solve the problem that slash pine cutting seedlings can survive, it is difficult for cuttings to take root in the process of slash pine cutting seedlings, the rooting time is long, and the cuttings are easy to rot. not well resolved

Especially for large-scale industrial cutting seedlings to improve their survival rate, the saplings grow robustly, the root system is developed, and the management of seedlings is convenient and efficient, the transportation of seedlings is light, and the subsequent high survival rate of afforestation has not been effectively solved.
