Abstract

Use of a compound of the formula: NdVO. tCSlNH,). as a growth promoter for plant growth & families of m tlikovyh, cabbage, maryovykh and solanaceous.

Description

The invention relates to a plant, namely, to chemical means of stimulating plant growth based on organoboron compounds. It is known to use boric acid and thiourea plants 1 as chemical stimulators of plant growth. The closest in terms of technical efficiency and positive effect to a stimuli-negative stimulator is a boron-ammonium-functional compound (BAMS) 2.; However, both boric acid and thiourea, and BAMS, are not effective enough as stimulators of plant growth in the families of small, cabbage solanaceous and marijuana. The purpose of the invention is to stimulate the growth of plants of these families possessing povivinnoy effektivnostyu. This goal is achieved by using the known compound, which is a complex of thiourea and boric acid of the formula, ltCS (NH5) 2 As a growth stimulator for the growth of the above families. The method of preparing the proposed compound (ij is described in and is that the boric acid is reacted with thiourea in an aqueous medium with heating (BO-70c). Example 1. The physiological activity of the preparation was tested under conditions of laboratory and field experiments in 1979 -1981 Seeds of cereal, cruciferous, solanaceous and marijuana were soaked in solutions of various concentrations before swelling, then germinated in distilled water. The germination energy and germination of seed were determined according to the method of rtoispytani minutes governmental agricultural crops (GOST 12047-66).

Optimal for pre-sowing treatment by soaking are 0,005-0,010% aqueous solutions of preyarate, which enhance the germination energy and increase. germination seeds n.

. Example 2. Stimulation of tomato plants of the variety Belyi naliz 241 was carried out by pre-sowing seeds soaking in a 0.00-5.5% aqueous solution of a boronthiourea compound (fl). Experiments have shown that the use of this compound for the pre-treatment of the seed tomato accelerates the onset of ripening and increases the yield of fruits,. I In tab. A: 2 shows the effect of pre-sowing treatment with a seed solution of boronthiourea compound (l) on the yield of tomato.

Table

Organic boron complex dineni, as can be seen from the table. 2, they increase both the overall yield of tomatoes and the input of early harvests and red fruits. Example 3, Stimulation of the growth of white cabbage plants was carried out by preseeding treatment of seeds. Seedlings were grown in peat pots in Russian greenhouses using biofuel. In tab. Figure 3 shows the effect of boron organic compounds on early cabbage yield Number One 147. Presowing treatment of seeds with a solution of boron-urea compound (1) accelerates the rate of leaf formation and increases the yield of early cabbage. Example 4. Stimulation of plant growth of fodder light varieties of Ekkendorfsk yellow was exaggerated by pre-sowing treatment with solutions of 1-bornic acid, thiourea, boron-emulsified (BAMS) and boron-thiourea (1) compounds under production conditions. Experiments were performed on light gray forest podzolized medium loamy soils. Preplanting seed treatment with organoboron compounds has a positive effect on an increase in the sedimentation surface and in the accumulation of the crop of root crops (Tables 4 and 5). 6 tab. Figure 4 shows the effect of seed pretreatment on the dingshik of the assimilation surface of fodder beet plants. In-table 5 shows the effect of pre-seeding seed treatment,

Example 5. Stimulation of buckwheat plants was carried out under field conditions by pre-soaking seed soaking in organoboron compounds. Before sowing, the seeds were dried to a flowable state.
