Embodiment 1

[0015] ① Disinfection treatment of light matrix nutrient bag and cutting seedbed: the light matrix nutrient bag used for cutting is soaked in a 0.1% potassium permanganate disinfectant, drained out after 7 hours and covered with a film for 2 days before being used for cutting. Before cutting, put the sterilized light matrix nutrition bags into the breeding plugs in turn, and place the plugs filled with the light matrix nutrition bags on the seedbed. Wash the light matrix with tap water to allow the disinfectant in the light matrix to flow out naturally , Use the outflow of disinfectant to disinfect the seedbed. When the light matrix nutrition bag is poured and washed until no red liquid flows out, the cutting can be done. .

[0016] ②Disinfection and rooting induction method of cuttings: In late May, select healthy, disease-free semi-lignified twigs (spring shoots) from fine woodcutting phoebe trees, and cut them into cuttings of 3~5cm, and keep each cutting. 2 leaves and 1 axi...

[0022] ① Disinfection treatment of light matrix nutrient bag and cutting seedbed: the light matrix nutrient bag used for cutting is soaked in a 0.1% potassium permanganate disinfectant, drained out after 9 hours and covered with a film for 2 days before being used for cutting. Before cutting, put the sterilized light matrix nutrition bags into the breeding plugs in turn, and place the plugs filled with the light matrix nutrition bags on the seedbed. Wash the light matrix with tap water to allow the disinfectant in the light matrix to flow out naturally , Use the outflow of disinfectant to disinfect the seedbed. When the light matrix nutrition bag is poured and washed until no red liquid flows out, the cutting can be done. .

[0023] ②Disinfection and rooting induction method of cuttings: In late September, select healthy, disease-free semi-lignified twigs (autumn shoots) from fine wood shavings plants and cut them into cuttings of 3 to 5 cm, and each cutting shall be kept. 2 le...

Abstract

The invention relates to a method for cultivating Machilus pauhoi with high cutting seedling planting percent by light-matrix nutrition bags. The adopted technical scheme is that in May to September, the nutrition bags filled with light matrices are placed in disinfectant to be soaked for 6-10h, are taken out, are hermetically covered by thin films for 2 days and are used for cuttage; before cuttage, the disinfected nutrition light-matrix nutrition bags are placed into breeding trays in sequence, and the trays filled with the light-matrix nutrition bags are placed on a seedbed; half-lignification twigs which grow in the current year are collected from excellent Machilus pauhoi plants and are cut into cutting slips, and the cutting slips are placed into complex liquid to be soaked, are taken out after 1h and are aired for 0.5h; the cutting slips are inserted into the disinfected light-matrix nutrition bags, an arch-shaped shed is built and is sealed by a thin film, 70 percent of transmissivity is kept, relative humidity in the film is kept to be over 80 percent, and disinfection and sterilization are performed with carbendazim regularly. After the Machilus pauhoi is subjected to light-matrix nutrition bag cutting seedling cultivation according to the method, the cuttage planting percent can reach over 95 percent.

Description

Technical field [0001] The invention relates to the technical field of vegetative cultivation of phoebe cypress seedlings, in particular to a method for cultivating high seedling rate by cutting and cultivating seedlings with light-substrate nutrient bags. technical background [0002] Machiluspauhoi (Machiluspauhoi) is a fine evergreen broad-leaved native tree that grows fast, has a beautiful appearance, and is versatile. In recent years, with the increasing demand for this tree species at home and abroad, a large number of natural wood shavings have been harvested, and many areas only retain a small number of natural young trees. The problem of shortage of market resources has become more prominent, and resource prices have been increasing year by year. The market price is 3000-3600 yuan / kg (fresh weight), which has attracted serious attention from relevant departments. Therefore, a large area of ​​artificial seedlings is urgently needed to solve the shortage of seedling resou...
