A method of obtaining yellowed tender leaves from rubber tree big tree

Abstract

The invention relates to a method for acquiring etiolated tender leaves from a big rubber tree. The method comprises the steps of cutting branches, carrying out sealing with paraffin, carrying out primary shading treatment, carrying out secondary shading treatment and carrying out sampling. Through the adoption the method, etiolated tender leaves which has adequate quantity and can meet the requirement of resequencing can be acquired from a big rubber tree, so that the method solves the problem that the etiolated tender leaves of an excellent single big rubber tree cannot be acquired and solves the problems that the site facilities is complex, a large number of branches cannot be gathered, the branch cutting workload is large, and the etiolated leaves die before reaching experimental requirements in other methods for acquiring etiolated tender leaves. In addition, the method has the advantages of simple facility requirement, simple and easy operation steps and low operation cost.

Description

technical field [0001] The invention relates to a method for obtaining yellowed young leaves of rubber trees, in particular to a method for obtaining yellowed young leaves from large rubber trees, and belongs to the field of agriculture and forestry. Background technique [0002] rubber tree( Hevea brasiliensis Muell. Arg.) is currently the only large-scale industrialized source of natural rubber. The natural rubber products made of its latex have good elasticity, wear resistance, and the production process is environmentally friendly. At present, it cannot be replaced by synthetic rubber. Because natural rubber has special needs in the fields of industry and national defense, it is an important strategic material and is highly valued by countries all over the world. Since natural rubber can only be planted in tropical regions, the land suitable for planting is limited. To expand production, the only way to increase production per unit area is to select high-yield varietie...

Problems solved by technology

[0004] The prior art discloses a method of using branches to prepare etiolated seedlings. If the disclosed technology is used to collect excellent single branch cuttings of rubber trees for shading and yellowing treatment, one needs a complete set of cutting sites and facilities such as seedbeds and sheds; The survival rate of rubber tree branch cuttings is low, and a large number of branches are needed. For some scarce rubber tree germplasm, a large number of branches cannot be obtained; third, due to the loss of latex in rubber tree cutting branches, the nutrient reserves are limited, and the yellowed leaves have not yet reached the experimental sampling requirements. That is, aging or death, unable to obtain enough yellow leaves of excellent individual rubber trees that can meet the requirements of resequencing

[0005] The yellowed young leaves of excellent individual rubber trees that can meet the resequencing requirements cannot be obtained by other methods that have been published or reported so far, and there is no method for obtaining yellowed young leaves of excellent individual rubber trees, especially those that can meet the requirements of resequencing. Method for obtaining yellowed young leaves on a single large rubber tree that requires resequencing
