Problems solved by technology

[0004] The existing seed-collecting mother trees are generally more than 30 years old. Due to various reasons, they have lost control for a long time, the trees grow and age, the quality of the seeds produced is not high, the seedlings bred have poor resistance, and the growth stamina of the seedlings is insufficient.
Therefore, it is not enough to only breed seedlings in the prior art, and the asexual propagation method must be adopted simultaneously to obtain the seedlings with excellent properties through cutting propagation of the branches on the excellent mother tree.

Embodiment 1

[0025] 1. Choose a good nursery site

[0026] The choice of nursery land should be in a place with convenient transportation, flat terrain or gentle slope, and good water conditions. At the same time, the nursery should also choose a sandy mud field with deep soil, loose soil, and rich organic matter. Such soil has good ventilation and water permeability, and can retain water and fertilizer, which is conducive to the expansion and growth of seedling root systems.

[0027] 2. Preparation of the nursery

[0028] Before cutting, the nursery should be fertilized and deeply plowed. It is generally required to apply about 5 tons of high-quality decomposed organic fertilizer per mu. First spread the fertilizer evenly on the ground, and then dig into the soil about 25 cm deep. Then use a rotary tiller to break up the soil clods to mix the mud and fertilizer evenly, then ditch and ridge according to the seedling raising requirements, and level the head of the bed to facilitate cuttin...

Embodiment 2

[0041] Substantially the same as Example 1, the difference is that a new method of Hackberry vegetative propagation comprises the following steps:

[0042] 1) Selection of nursery land: choose light clay loam soil with deep soil layer, loose soil quality and rich organic matter, which is not too viscous;

[0043] 2) Reconstruction of the nursery: First spread high-quality decomposed organic fertilizer evenly on the ground, then plow into the soil 30 cm deep, then use a rotary tiller to break up the soil clods to mix the mud and fertilizer evenly, then ditch and ridge to level the nursery The nursery ground is 1.5 meters wide and 12 meters long, and the nursery trench is 35 centimeters deep;

[0044] 3) Cutting preparation: From February to early March, collect 1 to 2-year-old spikes with a diameter of 2 cm from a 5- to 10-year-old healthy mother tree and cut them into 10-cm-long cuttings. Make sure that there are 2 complete and full buds. The upper end of the cuttings is cut ...

Abstract

The invention discloses a new method for asexual propagation of a hackberry. The method comprises the following steps of: selecting a nursery land; improving the nursery land; making cutting preparation work; cutting; transplanting and performing management work on cutting seedlings. The new method for the asexual propagation of the hackberry is an asexual propagation method which is adopted in the current production for the first time and fills the blank of hard wood cutting of the hackberry. The hard wood cutting method has a high rooting rate; the nursery stock cultured in the same year is strong, the degree of lignification is high, the diseases and pests are extremely few, the out-planting rate is high, the survival rate for the transplanting of the nursery stock provided for afforestation is high and the adaptability is strong. The method has the advantages of simple production process, normal cuttings, low cost, convenience in use and easiness in generalization and application.

Description

technical field [0001] The invention belongs to the field of asexual propagation of seedlings, and in particular relates to a new method for asexual propagation of hackberry. Background technique [0002] Hackberry is a deciduous tree of the genus Hackberry in the family Ulmaceae, which is distributed in most parts of our province and is a unique native tree species in our province. It is a good timber tree species and a better ornamental landscaping tree species. Hackberry is a positive tree species, slightly tolerant to shade, water and humidity, and also has a certain ability to resist drought. It likes fertile, moist and deep neutral clay soil, and is also resistant to light saline-alkali soil, with deep roots, well-developed root system, and strong wind resistance. The branches of hackberry are flat, the crown is wide, the shade is rich, the autumn leaves are golden, elegant and picturesque, it is the main shade tree in urban parks and courtyards. It has the characte...
