Description

The invention relates to forestry and agriculture, in particular to growth regulators of wood-shrub plants.

A known composition for stimulating plant growth based on peat, water-soluble active components and water (1). The disadvantage of this stimulant is the introduction of chemical compounds, which is associated with economic costs.

It is known to use magnetic (2) and degassed water (3) as a plant growth stimulator. The disadvantage of these stimulants is low efficiency, poor reproducibility, the difficulty of obtaining and storage.

It is known to use snow water as a plant growth stimulator (4). The disadvantage of using snow water is the seasonal limitations of its use.

The purpose of the invention is to increase the germination of seeds, stimulate their growth and expand the range of effective, cheap and affordable stimulants.

This goal is achieved by the fact that Florentine linear waters (fir, spruce, pine, larch, ledum, birch) are used as a stimulator of growth of woody plant seedlings - the second product formed during the distillation of essential oils.

When logging in the cutting areas of the Khabarovsk Territory alone, over 700 thousand tons of green wood waste remain annually, from which biologically active products are obtained - essential oils and Florentine waters, which are currently widely used by the population. The linear water formed during the distillation of oils was previously a waste product and was not used. Florentine waters contain a large number of biologically active substances: up to 0.2% of essential oil, vitamins, trace elements, minerals.

Experimental testing of running water was carried out in the greenhouses of the Khekhtsir experimental farm of the FGI “DalNIIILH” (Khabarovsk Territory) and OJSC “Melnichniy” (Primorsky Territory) on seedlings of Daurian buckthorn, Japanese quince, fluffy lilac, Korean pine, Gmelin larch, white fir, white fir.

Examples of experiments:

1. A month before sowing, the seeds of buckthorn, quince and lilac are soaked in running water (deciduous) for 24 hours at a temperature of 20-22 ° C, placed for stratification in sawdust sifted and moistened with the same water. Stratification is carried out for a month at a temperature of 18-20 ° C. In the early days of May, they are sown with lines on the ridges. The seeding rate is the same for the experimental and control crops, is 4-5 g per 1 meter of sowing furrow. Shoots appear on the 14-16th day after sowing. Crops of each breed are divided into four equal parts. One part remains the control, and the remaining three are allotted for irrigation with running water with dosages of 2.4 and 6 liters per 1 m ^{2 of} sowing.

The first watering is carried out 21 days after sowing. Subsequent watering is carried out with an interval of 7 days. In total, 6 irrigations are carried out during the growing season. Irrigation water rate, taking into account stimulants, was equal for all sites. In control plots, watering is carried out by river or lake water, in experimental plots - with a prescribed dosage stimulator.

During the summer, crops are subject to routine agricultural care; if necessary, additional irrigation with ordinary water is carried out. At the end of the growing season, 50 seedlings are selected from each plot using random sampling and the height of their stems is determined.

All experiments are laid in 3-fold repetition. Results are processed statistically. The data of specific experience are presented in table 1.

Table 1. The results of statistical processing of experimental irrigation stimulator (Florentine water) Doses of the stimulator for one irrigation, l / m ² Seedling height by the end of the growing season Daurian buckthorn Japonica Hairy lilac h ± m, cm % to control h ± m, cm % to control h ± m, cm % to control 2 23.6 ± 0.9 109 17.9 ± 0.6 107 11.4 ± 0.6 110 four 25.7 ± 0.6 120 21.6 ± 0.6 129 12.8 ± 0.5 123 6 22.0 ± 0.6 102 18.5 ± 0.6 110 10.4 ± 0.4 one hundred The control 21.6 ± 0.8 - 16.0 ± 0.5 - 10.0 ± 0.5 - Note: h - average height, m - average error

From the above data it follows that periodic irrigation with running water increases the growth of deciduous trees and shrubs. With an optimal dose of irrigation of 4 liters per 1 m ^{2 of} crops, the average seedling height exceeds the control by 20-29%. The accuracy of the experiments in all cases does not exceed ± 5%.

2. In the second version of the experiments, the effect of stimulants - linear water on the germination of coniferous seeds is tested.

Pre-sowing treatment of coniferous seeds is carried out with the above-mentioned linear waters. All preparations were tested in 4 variants: 25, 50, 75 and 100 cm ³ per 1 kg of seeds. Exposure time - 60 minutes. As a reference, the systemic funicidal bayleton was used. Coniferous crops are grown on specially prepared substrates from forest soil or peat deposited on loam. Crops are mulched with sawdust. The ground germination of Korean pine in the control experiment was about 280 pieces per 1 m ^{2 of} soil. After root treatment with Florentine waters, the germination rate increased from 14 to 36% depending on the stimulant taken and amounted to over 550 pieces per 1 m ² at a dosage of 25 cm ³ . With increasing doses of stimulants to 50, 75 and 100 cm ^3, germination increased from 30 to 46% (table 2).

Table 2. The results of pre-sowing soaking of seeds in Florentine waters at a dosage of 100 cm ³ per 1 m ² Name Name of plants and seed germination per 1 m ² ,% stimulant (water) White fir Ayan spruce Korean pine Larch Gmelin Fir 44 thirty 40 28 Spruce 32 33 38 24 Pine tree thirty 28 46 22 Larch 28 24 thirty 32 Ledum 24 fourteen 32 eighteen Birch twenty eighteen thirty fourteen

Pre-soaking of the seeds of larch Gmelin in Florentine waters gave an increase in soil germination by 14-32%.

Presowing soaking of Ayansky spruce seeds in solutions of Florentine waters gave an increase in germination by 14-33%; white fir - from 20 to 44%.

The data presented indicate the possibility of using Florentine (linear) waters: fir, spruce, pine, larch, ledum and birch as stimulants for the growth of tree-shrub plants.
