SU715079A1 - Method of stimulating potatoe tuber formation - Google Patents

Description

one

The invention relates to agriculture and can be used in the field of potato.

Methods are known for increasing potato yield and improving its quality by treating potato tubers before planting with stimulants, for example, rindite and thiourea 1.

A method of stimulating potato tuberization is also known, which consists in the fact that potato plants are treated with a stimulator with chloro-chlorine chloride at the end of bloom phase 2.

However, the known methods slightly change the quality of the potato, in particular the content of starch.

The aim of the invention is to increase the starch content in tubers of potatoes.

The goal is achieved by spraying the plants before budding with an aqueous solution of Na1-dimethyl-Na (y-chloroethyl) -hydrazine chloride at a dose of 2.4-2.7 kg / ha.

The specified chloride has a structural

This treatment contributes to an increase in underground shoots, accelerates tuberization, leads to faster maturation of tubers, an increase in starch accumulation in tubers, and an increase in potato yield per hectare.

Example 1. Belarusian early potatoes were grown in pots. Before budding, plants were treated with a solution of M1Y-dimethyl-S (B-chloroethyl) -hydrazine chloride in various doses. For comparison, a variant with treatment with (2-chloroethyl) trimethylammonium chloride is introduced. The results of the experiments are given in table. The most effective was the dose of the drug 2.5 kg / ha, the number of tubers increased by 20% compared with the control. Starch content in tubers increased by 18%.

Example 2. Belarussian Early Variety Potatoes were grown in field experiments. Before budding, the plants were treated with a solution of NY-dimethyl-N (US-chloroethyl) -hydrazine chloride in an optimal dose of 2.5 kg / ha.

Test results: Ni chloride N-dimethyl-N (yj-chloroethyl) -hydrazini.

From the data presented in the table, it follows that the processing of plants of potatoes

before budding with NI N-dimethyl-N (j3-chloroethyl) -hydrazine chloride solution, it accelerates the maturation of tubers by an average of 7-8 days, which is very important for early and middle ripening varieties. An increase in yield of tubers by an average of 20% and starch content of tubers by 1% gives an additional income of 150-200 rubles per hectare.

For the industrial production of hydrazine salts, there is a fairly well-stocked raw material base, so they can be widely used in agriculture.

Claims (1)

Claim A method of stimulating potato tuberization, including treating the aerial parts of potato plants with a chemical compound, characterized in that, in order to increase the starch content in the potato tubers, the treatment is carried out in the period before budding with the chemical compound at a dose of 2.4 - 2.7 kg / ha, the quality of which is used chloride ΝιΝ-dimethyl-N (/ 1 chloroethyl) -hydrazinium.
