Problems solved by technology

[0003] At present, the cultivation of tree seedlings of Liriodendron genus mainly includes seed breeding and branch cutting. However, due to the physiological and genetic characteristics of the tree species itself, these two seedling cultivation methods have shown great disadvantages.
The embryonic rate of the winged seeds of Liriodendron species is only 1% to 3%, and having embryos cannot guarantee normal germination, so its germination rate is extremely low; in addition, the prior art is all artificial seed collection, because Liriodendron The genus tree species belong to tall trees, and the aggregated fruits are mostly located in the middle and lower parts, and the nutrient supply and sunlight exposure of the middle and lower branches are insufficient, resulting in poor development of seeds in the aggregated fruits, and the maturity time of the seeds in the aggregated fruits is inconsistent, resulting in the growth of Liriodendron species. Germination rate is very low
The use of branch cuttings for vegetative propagation is a relatively common method of seedling cultivation on forest trees, but Liriodendron genus species, whether it is hard branch cuttings or young branch cuttings, show many problems such as difficult rooting, long rooting time, less rooting, and difficulty in transplanting. question
In addition, the use of branch cuttings for seedling cultivation has higher requirements for cultivation facilities and management techniques, which will greatly increase the cost of tree seedling cultivation

Embodiment 1

[0042] In 2017, the experiment was carried out in a field of mixed Yamei horse-gown in Yangxi Town, Anfu County, Ji'an City, Jiangxi Province. The age of the Yamei horse-wax tree is 18 years old, the forest density is about 50 trees / mu, the average tree height is 35.78m, and the average diameter at breast height is 35.78m. It is 37.43cm, the slope of the woodland is about 7°, and the area is about 20 mu. This time, 10 mu of forest land is cultivated for forest land and seedlings, and the remaining 10 mu is used as a control, and the control woodland is not subjected to any treatment. Follow the steps below to deal with the forest land: thinning in early February, removing some trees that do not grow well, and other miscellaneous trees. After thinning, the forest canopy density is about 55%, and the side branches below 3m are pruned. , thinning is carried out every 4 years; ditching, fertilization and soil covering work are carried out at the end of February, the depth of ditchi...

Embodiment 2

[0049] In 2016, the experiment was carried out in a mixed Yamei horse-gown forest in Maquan Town, Yujiang District, Yingtan City, Jiangxi Province. The Yamei horse-gown forest is 16 years old, the forest density is about 60 trees / mu, and the average tree height is 25.53m , the average diameter at breast height is 32.26cm, and the area is about 2000 mu. In this experiment, 30 mu of woodland was selected for the forest seedling cultivation test, and the selected woodland slope was about 12°. Three treatments were set up in the experiment: ①Example 2 woodland was treated according to the method of Example 1; ②CK1 was only subjected to thinning and pruning, and the woodland soil was not treated; ③CK2 did not undergo any treatment. In February and October 2017, and in February and October 2018, 20m×20m quadrats were set up to investigate the emergence of seedlings at the beginning of the year and the seedling storage at the end of the year for two consecutive years. The results are...

Abstract

The invention belongs to the technical field of protection and utilization of plant resources, and in particular relates to a method for cultivating tree seedlings of the genus Liriodendron. The method for cultivating Liriodendron forest tree seedlings provided by the invention directly utilizes forest land resources to increase the nutrient supply and photosynthesis of the mother tree through thinning, pruning and fertilization, so as to improve the quality of the seeds; The fallen leaves of tree species are mixed into the soil to keep the soil loose and air-permeable, and promote seed germination; furthermore, by spreading agricultural water-retaining agent and chaff ash, the water-holding capacity and air-permeability of the soil can be increased, and the cost of irrigation can be reduced; The surface fertilizer promotes the growth of seedlings and strong roots, and increases the survival rate of transplanting. The cultivation method of Liriodendron tree seedlings provided by the invention not only has a high seedling emergence rate, but also is simple and easy to implement, saves land, has low technical difficulty, and is easy to popularize. Rapid development has a great impetus.

Description

technical field [0001] The invention belongs to the technical field of plant resource protection and utilization, and in particular relates to a method for cultivating tree seedlings of the genus Liriodendron. Background technique [0002] Liriodendron is a tree species of Magnoliaceae, which is a relic species of the Tertiary period. It is a relatively ancient tree species and has been listed as a national second-class rare and endangered tree species. Liriodendron, as the surviving and endangered bispecies on earth, is considered to be the original group of angiosperms. In addition to being used for cross-breeding, it is also of great value for the study of the origin, distribution and phylogeny of flowering plants. In addition, Liriodendron species has unique and beautiful leaves. It is a precious ornamental tree species in parks and urban greening. It can also be used as a shade tree and street tree. Its wood is used for construction, furniture, joinery, etc. Catalonia ...
