SU1423054A1 - Stimulant for resinification when tapping pine trees - Google Patents

Abstract

This invention relates to a forestry owner. The purpose of the invention is to increase the yield of resin. The stimulator of resin release contains, in wt.%: The hydrel is 0.5-5.0; diethanolamine 0.2-2.0 and water - the rest. Diethanolamine performs the function of activating the release of ethylene from the hydrel, shifting the pH of the working solutions towards a weak alkaline reaction. The stimulating effect of the mixture considerably exceeds the sum of the effects of input w, their components into it, which gives grounds to state their synergism. The use of a new stimulator makes it possible to obtain a gum yield of 6–13% higher. 1 tab.

The invention relates to forestry, in particular to tapping of coniferous trees.

The aim of the invention is to increase the yield of sap when tapping pine.

A combined use of a hydrorel and diethanolamine is proposed in the following ratio of components in the stimulator, wt%: Hydrel 0.5-5.0

Diethanolamine 0.2-2.0

Water the rest.

The effect of the hydrella stimulator is a-; but above all with its ability to make ethylene gas. The decomposition of the hydrel in solution with the formation of ethi-: lene most intensely proceeds in an alkaline medium.

 Diethanolamine in the proposed stimulator performs the function of activating the release of ethylene from the hydrel, shifting the pH of the working solutions towards a weakly alkaline reaction. In addition, the addition of diethanol-amine increases the viscosity of the working solutions, thereby improving the period of contact of the stimulator with the tissues of the tree when applied to the trim. The above CONDITIONS determine the synergistic effect of the action of the developed stimulator. To test the effectiveness of the proposed stimulant formulation, three mixtures of components were prepared.

Comparative effectiveness of the proposed stimulator and its components

Note: Efficiency - Carrodecymetr subnote.

Stimulator 1 (minimum concentration of components): (hydrel and diethanolamine were successively dissolved in water) in the following ratio of components, wt.%: Hydre 0.5

Diethanolamine 0,2

Water the rest.

Stimulator 2 (average values of component concentrations): hydrel and diethanol-amine in the stimulator are taken in the following ratio, wt%:

Hydrel

Diethanolamine Water

2.5 1.0

Rest

Stimulator 3 (maximum concentration of components): the hydrel and diethanolamine are dissolved in the following ratios, wt .-%:

Hydrel5.0

Diethanolamine2,0

Water the rest.

An infusion (extract) of fodder yeast was prepared at a concentration of 2.5% according to the active ingredient, which was governed by approved regulations.

The results of tapping using the proposed and known stimulators are presented in the table.

The data in the table indicate the high effectiveness of the proposed stimulator, both with respect to the base object used by the industry (yeast) and with respect to each component of it. At the same time, the stimulating effect significantly exceeds the sum of the effects of the INPUTS. THEIR components in it, which gives grounds to state their synergy.

The use of a new stimulator makes it possible to obtain a gum output, 6–13% higher than the output, with a hydrel.
