FIELD: agrochemistry.
SUBSTANCE: invention relates to a method for producing a plant growth activator, which consists in treating cellulose or a starting material containing it with 85% wt. orthophosphoric acid in an amount of at least 16.6 wt. parts of acid per 1 part of cellulose at a temperature of 18-30 ºC for 20-150 hours and further neutralization of the product with ammonia to isolate carbohydrate phosphates from the reaction mixture. The invention also relates to a method for separating carbohydrate phosphates from a mixture with phosphoric acid and a plant growth activator.
EFFECT: simple and inexpensive way to obtain carbohydrate phosphates, as well as to study their activity as plant growth activators.
