Данное исследование описывает влияние азотных, фосфорных и калийных удобрений на рост и урожайность кок-сагыза при помощи эксперимента в полевых условиях. Мы обнаружили, что правильное внесение азотных, фосфорных и калийных удобрений может значительно увеличить урожайность корней, выход каучука и общего сахара у кок-сагыза. При внесении количества азотно-основного удобрения, увеличенного с 0 до 107,2 г м–2, тенденция изменения урожайности каучука соответствовала явному увеличению; при внесении количества фосфорноосновного удобрения, увеличенного с 0 до 10,5 г м–2, тенденция изменения урожайности каучука также соответствовала значительному увеличению; при внесении удобрения на основе калия, увеличенного с 0 до 35,3 г м–2, тенденция изменения урожайности каучука соответствовала наибольшему увеличению.Согласно нашим рекомендациям, в местных почвенных условиях экспериментальной станции в Харбине (N45.592729°, E126.581668°) количество основного удобрения должно составлять: 107,2 г м–2 мочевины, 43,4 г м–2 суперфосфата кальция, 10,5 г м–2 хлористого калия.</p></abstract><trans-abstract xml:lang="en"><p>Taraxacum kok-saghyz (TKS) is a promising natural rubber plant. In the current study we investigated effects of nitrogen, phosphorus, and potassium base fertilizers on growth and yield of TKS through the field experiments. We found that appropriate application of nitrogen, phosphorus, and potassium base fertilizers can significantly increase root, rubber and total sugar yield of TKS. The TKS rubber yield enhanced significantly when the amount of nitrogen and phosphorus, potassium increased accordingly to 107.2, 10.5 and 35.3 g m–2. Maximum accumulation of rubber in the TSK roots is caused by application of potassium fertilizer.According to the obtained results the recommended amount of base fertilizers under conditions of Harbin Experimental Station (N45.592729°, E126.581668°) is 107.2 g m–2 of urea, 43.4 g m–2 of calcium superphosphate, 10.5 g m–2 of potassium chloride.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кок-сагыз</kwd><kwd>азот</kwd><kwd>фосфор</kwd><kwd>калий</kwd><kwd>базовое удобрение</kwd><kwd>каучук</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fertilizer effects</kwd><kwd>rubber</kwd><kwd>sugar</kwd><kwd>leaf biomass</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была поддержана Фондом научных исследований Академии наук провинции Хэйлунцзян в рамках гранта № KY2019ZR02; работа выполнялась в рамках государственного задания согласно тематическому плану ВИР по проекту № OFGEM-2022-0005.</funding-statement><funding-statement xml:lang="en">The work was supported by the Scientific Research Fund of Heilongjiang Academy of Sciences under grant number KY2019ZR02; the work was performed within the framework of the state task according to the theme plan of VIR, Project No. FGEM-2022-0005.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Baligar V.C., Bennett O.L.
