Embodiment 1

[0070] Grafting methods include bud grafting or branch grafting. What is used in this embodiment is the split grafting method in branch grafting. It is generally carried out before the rootstock buds germinate or when they start to germinate without spreading leaves. If the damage by diseases and insect pests is too late, it will easily cause the tree to weaken and even die in winter. In practice, spring grafting is most suitable from 10 days before germination to the germination period. At the same time, it is better to survive grafting in high temperature and sunny weather. The optimum temperature is 15-25°C, and the absolute humidity of the soil is 20-25%. The steps are:

[0071] (1). Select 3 poplar branches full of buds as the scion, cut a long 3 cm long bevel on both sides of the lower end of the scion, the bevel should be smooth, and then soak the wooden wedge-shaped lower end of the scion in the grafting liquid for subsequent use;

[0072] (2). Select Zhongtian poplar...

[0081]Grafting methods include bud grafting or branch grafting. What is used in this embodiment is the split grafting method in branch grafting. It is generally carried out before the rootstock buds germinate or when they start to germinate without spreading leaves. If the damage by diseases and insect pests is too late, it will easily cause the tree to weaken and even die in winter.

The optimum temperature is 15-25°C, and the absolute humidity of the soil is 20-25%. The steps are:

[0082] (1). Select 4 golden crown poplar branches with full buds as the scion, cut a 5 cm long bevel on both sides of the lower end of the scion, the bevel should be smooth, and the angle is moderate;

[0083] (2). Select the Zhongtian Populus plant that grows robustly and has no damage by diseases and in...

Abstract

The invention relates to a cultivation method of golden leaf poplar trees. In the method, a populus tree species in salicaceae is taken as a rootstock, and the populus tree species in the salicaceae is taken as a scion for grafting. The method comprises the following steps: (1) selecting a scion branch with 2-4 full buds, cutting the lower end of the scion into a wooden wedge shape; (2) cutting off the rootstock at a position where the straight rootstock bark has no knot, and splitting a vertical split mouth with the depth slightly longer than the scion in the middle of a cutting plane; (3) inserting the lower end of the scion into a cut of the rootstock, binding and properly sealing an interface with plastics; (4) removing rootstock shoots in time; and (5) removing the binding plastics after the scion survives, thus completing the cultivation of color leaf poplar trees. The method is characterized by a few steps and easy operation, and the cultivated golden leaf poplar trees have the advantages of salt and alkali resistance and ornamental value, are good materials for urban and rural road forest networks (especially for urban greening), are applicable to being planted in saline-alkali tideland and infertile soil areas, and are a tree species which enriches and expands urban greening gardens and has ornamental value.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating golden leaf poplar. Populus plants were selected as rootstocks and Populus plants were used as scions, and the method of grafting was used to cultivate golden-leaf poplar trees that can resist salt and alkali and have ornamental value. Background technique [0002] Trees are very important to people. Large-scale tree planting can purify the air and reduce soil erosion. At the same time, it also beautifies and decorates the modern city made of steel and concrete, so that people living in the city can breathe fresh air and Different colors can be appreciated. [0003] Salicaceae plants are mainly distributed in the northern temperate zone and subtropical zone, and a few species are distributed in the tropics and southern hemisphere. In China, it is distributed in all parts of the north and south. The root system of the undergraduate plants is we...
