SU506361A1 - Method of stimulating plant growth - Google Patents

Description

The invention relates to the field of agriculture and can be used to stimulate the growth and development of agricultural crops. There is a method of stimulating plant growth, which includes treating seeds and / or plants with an aqueous solution of a stimulator 1, 2, 5-trimethyl-4- / dimethylphosphone / piperidol-4. The disadvantage of this method is that the use of a stimulator does not make it possible to increase the yield of cultivated plants and improve the quality of the target products. The purpose of the invention is to increase the yield of cultivated plants and improve the quality of target products. According to the invention, the goal is achieved by using hydrochloride-2, 2, 5-trimethylpiperidone-4 (the conventional name AEC-4) as a stimulator. The method of drying is described as follows. A study of the effect of 2, 2, 5-trimethylpiperidone-4 stimulator on the yield and quality of tomatoes and onions was carried out using the method of soaking seeds or spraying plants. For this, vegetative and field experiments were performed. The repetition of vegetative experiments eight times. Soaking of seeds in freshly prepared stimulator solutions with a concentration of 0.001-0.01% lasted for 16 hours. Field experiments with tomatoes and onions were laid in four replications. Spraying of plants with stimulator solutions was performed twice: tomatoes in the period of mass flowering of the first brush and after 13-15 days, onions at the beginning of bulb formation and after 13-15 days. 1, 2, 5-trimethyl-4 dimethylphosphone, piperidol-4 (ACA-1) was used as a reference stimulator, and water was used as a control. As a result of the vegetative experiments performed, the most optimal concentrations of 0.01% and 0.001% aqueous solutions of the stimulator were established. According to the vegetation experiments of 1971-1973. when spraying tomato plants with 0.01-0.001% aqueous solutions, the increase in yield averaged 20-22% compared with the control. In tab. 1 shows data on the effect of the AES-4 drug on the yield of tomato varieties “Soviet 679 in the vegetative experiments of 1973.

Table 2 presents data on the effect of the AES-4 drug on the yield of tomato varieties

table 2

As can be seen from the table. 1 and 2, the AES-4 preparation at a concentration of 0.001%, when spraying tomato plants during the mass flowering period of the first brush and after 15-16 days, increases the yield by 26-27%, which is 98 centners.

As can be seen from the table. 3, the AES-4 preparation at a concentration of 0.01% yields 18 centners per hectare of additional yield compared with the control, which is 2 centners per hectare more than the yield obtained using the preparation ACA-1.

Field experiments to study the effect of AES-4 on the yield and quality of sugar beet were carried out in quadruplicate. The exposure time is 18 hours. The area of each experiment is 125 meters. Sugar beet seeds were treated with water plants in field experiments in 1973 to study the effect of the AES-4 drug on the onion yield were confirmed by those obtained under the conditions of vegetation experiments 1971-1973.

Data on the effect of the AES-4 drug on the yield and sugar content of sugar beet varieties Yaltushkovskoye sunshine under field conditions of 1973 are given in Table. four.

As can be seen from the table. 4, the use of AES-4 allows to increase the yield of sugar beet compared to the control by 87 centners per hectare, and compared to the preparation ACA-1 by 15 centners per hectare, the sugar content increases by 0.8% and 0.2%, respectively,

or it makes it possible to obtain an additional 15.1 centners per hectare of sugar compared with a control of 3.0 centners per hectare compared to the preparation ASA-1.

The results of field experiments to study the effect of the AES-4 drug on the yield of tomatoes, onions, and sugar beets show that the proposed drug is a highly effective stimulator of the growth and development of agricultural crops.
