Method for fast breeding Chinese jongye poplar in coastal region

Abstract

The present invention relates to a rapid propagation method of poplar with red leaves in the coastal area. The method comprises nursery selection, nursery arrangement, cutting cutting production, cutting, and post-planting management; the cutting cutting production includes the following steps: in February to March, Choose hard branches with a diameter of 1-2cm, soak the branches in clean water for 3 days before cutting, change the water once a day, after soaking, cut into cuttings with a length of 10-15cm each, with 3-4 buds per section , the upper incision is 1-1.5cm away from the top bud, and the lower incision is 0.5-1cm away from the bottom bud, all of which are cut flat with sharp scissors without leaving any splitting wounds; the prepared cuttings are used with a concentration of 100-200mg / g Soak in naphthalene acetic acid solution for 12-24 hours. According to the method of the present invention to propagate the red leaf poplar, on the one hand, the emergence rate of the cuttings can be guaranteed, and the emergence rate can reach more than 90%;

Description

technical field [0001] The invention relates to an arbor propagation method, in particular to a rapid propagation method of red leaf poplar in coastal areas. Background technique [0002] Red leaf poplar (Populus deltoids cv. Zhonghuahongye), also known as Chinese red leaf poplar and color-changing poplar, is a new species of poplar cultivated by Professor Cheng Xiangjun and Professor Zhu Yanlin in 2000. This poplar species is a tall tree with a straight and round body and a plump crown. The leaves are large and thick, and the color changes with the seasons very obviously. Adult red-leaved poplar is 3-5cm long between nodes, 12-23cm wide and 12-25cm long, thick and blunt-toothed, broadly ovate, longer than wide, apex acuminate, heart-shaped leaf base, branch edge The lines are obvious, the skin color is deep purple, and the lenticels are few and obvious; the bud body is purple-black, the tip of the bud is curved inward, and it is dry, and the terminal bud is purple-black, t...

Problems solved by technology

[0003] Due to the impact of soil salinization in coastal areas, the survival rate of poplar cuttings is relatively low, and the color leaf period of poplar planted is short, which affects the landscape effect of poplar to a certain extent.
