Үсемлек өчен күпме генә түгел, кайчан икәне дә мөһим

Безнең тикшеренү ничек үткәрелде

Һәр бодай үсемлеге бер элементы булмаган эремә салынган аерым савытта үсте. Бу нәкъ шул элемент җитмәгәндә үсемлек белән нәрсә булганын һәм ул күпме көтә алганын күрергә мөмкинлек бирә.

Бодай гына түгел

Кукуруз тәҗрибәсе 2026

2026 елда VMU теплицасында кукуруз да шул ук принцип буенча үстерелә: һәр үсемлек бер элементы җитмәгән аерым савытта үсә. Кальций (Ca) җитешсезлеге дә өйрәнелә.

Ни өчен BBCH 30–37 фазаларына игътибар кирәк?

Безнең тикшеренүдә язгы бодай гидропоника ысулы белән үстерелде. Бер макроэлемент җитешсезлеге BBCH 23 фазасында башланды һәм 21, 28 яки 35 көн дәвам итте; бу чорлар якынча BBCH 30, 32 һәм 37 фазаларына туры килде. Тәэсир элементка һәм озынлыкка бәйле булды: мәсәлән, 28 көнлек калий җитешсезлеге продуктив куаклар санын киметте, ә азот, фосфор яки кальций җитешсезлеге озайган саен биомасса югалтулары артты.

Мөһим: бу көннәр санын туфракка турыдан-туры күчерергә ярамый. Туфракта җитешсезлек 3–5 тапкыр тизрәк үсә. Туфракта үсемлекләр еш кына су җитмәүгә дә очрый, ә су беркайчан да җитмәгән булмаган гидропоникада үсемлек саклану халәтендә озаграк кала ала – ул сабыррак.

Басу тәҗрибәсеннән

Басуда вакыт берничә тапкыр тизрәк уза

Гидропоникада үсемлектә су һәрвакыт бар, шуңа күрә туклану җитмәү әкрен үсә. Туфракта, безнең агрономнар күзәтүләре буенча, шундый ук җитешсезлек 5–10 көндә, ә корылыкта бары 1–3 көндә үсә. Гидропоникадагы өч атналык ачлык басудагы бер атнага, ә коры чорда берничә көнгә генә тиң булырга мөмкин.

Шуңа күрә басуда берничә көн соңару да инде соң булырга мөмкин: үсемлек башка процессларны кабыза һәм аннары аңа башка элементлар кирәк булырга мөмкин. Җитешсезлекне күзгә күренгәнне көтмичә үлчәргә кирәк.

Басудагы вакытлар UAB „Žemdirbių konsultacijos“ агрономнары күзәтүләренә нигезләнгән; алар гидропоника тикшеренүе нәтиҗәсе түгел.

Практик белгеч нәтиҗәләре

SmartAgrometer җитешсезлек күрсәткәндә нәрсә эшләргә

Һәр җитешсезлекне бер төрле коткарырга кирәкми. Кайвакыт дөрес карар – басуга акча салуны туктату һәм ул ашламаларны башка, яхшырак басуга бирү. Түбәндә – безнең тикшеренүләрдән һәм басудагы эштән практик агроном ясаган нәтиҗәләр.

Практик агроном һәм VMU докторанты Ernestas Petrauskasның UAB „Žemdirbių konsultacijos“ тикшеренүләре һәм басудагы эше нигезендә ясаган нәтиҗәләре. Фәнни нигез: Petrauskas et al., 2026, Plants 15(7), 1094.

Тәҗрибә фотолары

12 җитешсезлек. Аларны күз белән аера алыр идегезме?

Шул ук көзге бодай тәҗрибәсе: һәр үсемлеккә бер элемент җитмәде. Кайбер аермалар ачык, ләкин күбесе күзгә күренми диярлек – бигрәк тә басуда, анда барлык үсемлекләр дә охшаш. SmartAgrometer җитешсезлекне саннар белән күрсәтә.

12 туклыклы элемент

Һәр элемент бодай өчен нәрсә эшли, аның җитешсезлеге ничек күренергә мөмкин, кайчан иң куркыныч һәм аны соңрак төзәтеп буламы.
