Embodiment 1

[0025] A method for asexual and rapid propagation of wild pagoda seedlings includes the following steps:

[0026] S1. Screening of mother plants: Carry out continuous observations for at least 3 years of the A. papyrifera plants to be selected as mother plants, with a large amount of fruit in each year, good fruits, and almost no large and small phenomena as candidate mother plants. Specifically, select the candidate mother plants that entered the fruit-bearing period that year and test their age. After the fruits are mature, all the fruits are picked and weighed, and the fruits are sent to the same testing agency to test the oil content of the whole dried fruit base using the same testing method. rate. For trees of the corresponding age, those that meet both the fruit bearing and oil content in Table 1 are regarded as mother plants.

Embodiment 2

[0034] A method for asexual and rapid propagation of mountain tongs seedlings mainly includes the following steps:

[0035] P1. Screening of mother plants: The method for screening mother plants in this example is the same as that in Example 1.

[0036] P2. Root harvesting and burying: according to the screening method of the mother plant, the daughter and mother plants of Fructus vulgaris are selected and cut from the roots of the mother plants with a diameter of 0.8-1cm and a length of 8-10cm, and the cut roots are soaked for rooting Buried in the seedbed after the medicine. The soaking method is: soaking in low-concentration rooting agent for 1h-6h or soaking in high-concentration rooting agent for 1-5 seconds. The concentration of the low-concentration rooting agent is 1-10 ppm; the concentration of the high-concentration rooting agent is 100-10000 ppm. The low concentration and high concentration rooting agent adopts STZ-PP1 type rooting agent. 6 hours before burial, use 1 ...

Abstract

The invention discloses an asexual rapid propagation method for idesia seedlings. The asexual rapid propagation method mainly comprises the steps of screening stock plants, cutting orchard and preprocessing, cutting orchard and cutting, raising seedlings and managing, taking the seedling out of gardens and performing subculture. Compared with the tissue culture in the prior art, the asexual rapid propagation method for idesia seedlings is simple in step, low in requirements of technology and devices and low in cost; and meanwhile, the culture of the idesia seedlings adopts branches of the excellent stock plants, so that the large-scale rapid propagation can be realized.

Description

Technical field [0001] The invention belongs to the technical field of vegetative and rapid propagation of plants, and specifically relates to a method for asexual and rapid propagation of wild pagoda seedlings. Background technique [0002] Mountain tongzi is a neutral shade tree species. It likes light, and its saplings are more tolerant to half shade, and it likes a mild and humid climate. It is also more resistant to cold and drought. It does not have strict requirements on the soil, but it is in deep, fertile and moist sandy loam It grows well in the middle. Born in deciduous broad-leaved forests and coniferous broad-leaved mixed forests such as hillsides and depressions in low mountainous areas 400-2500 meters above sea level, usually concentrated in mountains at an altitude of 900 meters (south of the Qinling Mountains) to 1400 meters (southwest) . The wood is soft and can be used for construction, furniture, appliances, etc.; it is an excellent tree species for the cons...
