(54) RESPONSEABLE STIMULATOR WHEN CONNECTING CONIFEROUS BREEDS

I

The invention relates to the field of song management and can be used in leshozes for livestock production.

A pitch stimulator is known for tripping conifers, consisting of an aqueous solution of malonic acid 1.

A disadvantage of the known stimulator is the insufficient growth of the gross collection of the resin.

The aim of the invention is to increase the gum release and the quality of the turpentine.

This goal is achieved by using as a stimulator of resin release during tripping of conifers of the acid yellow light resistant dye (n. Sulfofenyl) -3-methyl-4-phenylazo-5-oxy-pyrazole.

The dye is a yellow crystalline substance that is readily soluble in water, not poisonous, not extremely dangerous, does not lose its properties in moist air.

It is well preserved in the form of a paste of 50% moisture content and higher, which is most effective when used under production conditions 2.

The use of the proposed stimulator for tapping softwood does not require changing the technological mode of tapping and the tools used.

Example. To test the effectiveness of the proposed stimulator for tripping conifers, four stimulant compositions were prepared, each containing, in wt.%:

Composition 1. The lowest concentration. Yellow light resistant acid dye 0, 1 Water Else

Composition 2. Optimal concentration.

Yellow light resistant acid, dyeI, 0

The rest is sour. 3 The rest is acid

1.0 Else

The results of tapping are presented in table 1.

It can be seen from the above data that the treatment of the working surface with the proposed resin release stimulator makes it possible to increase the output of the resin compared to the known stimulator by 16-50%, which is equal to the annual increase in the gross collection of the resin of 14-16 thousand tons.

The yellow light resistant acid dye, falling into the sap, interacts with turpentine, finds 1 cim in the latter and leads to a rapid curing of the sap in the receiver (a monolithic piece of sap is formed). Each successive quantity of turpentine, flowing into the receiver, replenishes this piece of monolith resin. Instant barrasing of turpentine increases its quality,

T.K. the ingress of litter and water into this mass is reduced. The natural amount of water dissolved in the resin is within the normal range; no additional water is absorbed into the monolith of the resin obtained. Turpentine is easily selected from the receiver without the use of assembly blades.

Data on the content of water and litter and turpentine in the resin, collected during the experiments with the proposed stimulator, are given in Table 2.

The yellow light resistant colorant easily distills from the resin and does not degrade its quality. When distilling off a yellow light resistant acid dye, turpentine was present in the condensate. The presence of turpentine is 0.67% by weight.

It can be seen from the above data that the sap obtained with the proposed stimulator contains the minimum amount of water and litter; during processing, it allows the turpentine to be distilled from the sap completely.

The reduced content of turpentine in the sap is due to the fact that the experiments were conducted at the end of the season when it was. the amount in the sap is dramatically reduced.
