Study on Cutting Propagation Technology of Pterocarya stenoptera C. DC

ABSTRACT

This paper is mainly about cutting propagation of Pterocarya stenoptera C. DC, especially hardwood cutting propagation. The cutting propagation techniques of Pterocarya stenoptera C. DC are mainly inverted storage, mother plant rejuvenation, biochemical treatment and full light intermittent spraying. In this experiment, the effects of different parts, different lengths, and the different coarseness (other conditions) on the Cuttage Propagation of Chinese Maple young were studied in three aspects. The results showed that: the best parts of cutting propagation of P. Maple were: base, 14-16cm and 6-9mm. Moreover, according to the actual effect and the evaluation of the root effect index, so in order to obtain higher survival rate and ideal income, the branches of 14-16cm and 6-9mm of the base of maple poplar should be selected as inserts. The 1 year old seedling stem is used for cutting the ear with a certain length of the base (generally greater than 10cm).The cuttings are not suitable to be done near the tip. And 1 year old seedlings are used as cuttings, and the base material is beneficial to the cultivation of the strong seedlings. The value of maple young is high, including medicinal value, ecological value and application value of wood. High value determines its position and application prospect in today’s social production. On the basis of ensuring the survival rate of maple young, a series of Cuttage Propagation Technology is carried out, and the prospect of its application can be seen from it. Get great benefits.

Key words:Chinese ash;Hardwood cutting propagation;Branches of different parts; Branches of different coarseness;Branches of different lengths
