Description

CD 00 SL

The invention relates to the field of agriculture and forestry, namely to chemical means of stimulating the growth of plants.

It is known to use indolyl fl with vinegar fl and succinic acids ZD as a plant growth stimulator.

However, the known plant growth promoters are not sufficiently active.

The 2-deoxy-B-arab-hexhexone .1 calcium and the method for its preparation are known.

The purpose of the invention is to increase plant growth-promoting activity. .

A goal is achieved by using a calcium 2-deoxy-B-arabinohexonate of formula

The effect of the proposed compound on the survival rate of cuttings of spruce barbed blue

For 20 hours, they were treated in aqueous solutions at a concentration of 50.100 and 155 mg per 1 liter of water (in each experiment, 100 pieces of cuttings). Next, the cuttings were washed with running water and, together with the control variant, they were planted without treatment in the sandy soil in greenhouse conditions (air temperature 20-25 C, Relative humidity - 80-90%). The beginning of root formation in cuttings was observed 12-16 days after planting. The degree of stimulation is determined by the number of roots, the nature of their formation, and the length of the portion of the stem on which the roots are laid. The most active drug concentration was 100 mg / l sovfi.

Similarly, winter cuttings of decorative coniferous spruce trees of the spiny blue (Picea pungens Engeim) were rooted. The proposed drug compared with the control variant (without stimulant treatment) gives a high result. According to the results of the survival rate of spruce barbed, the activity of stimulation of the test compound exceeds the activity of the potassium salt of tetro-auxin (indolylacetic acid).

The results are shown in Table. one.

in distilled water in the same J mode. Next, the seeds were washed with running water. The treated and control seeds were grown in a thermostat according to GOST 12038-66. Accounting for germination was made on the fourth (germination) and eighth (full germination) days. The test results are presented in Table. 2

The effect of the proposed compound on germination

 As can be seen from table 2, the proposed connection increases the germination of beans by 17-40%.

The results of field experiments have shown that the preliminary o5 / processing of grain and. grain-bole crops (maize, beans) are a great stimulant, which significantly increases not only the activity of seed germination, but also yields
