Boron tuaj yeem muab sib xyaw rau hauv cov chiv qhuav xws li 0-0-60 lossis 0-14-42. Boron chiv muaj xws li borax (11 feem pua boron) thiab borate granular (14 feem pua boron). Solubor (20 feem pua boron kua) yog siv foliar thiab yuav tsum tau siv ntawm tus nqi pom zoo rau cov qoob loo tshwj xeeb.
Tsis tas li ntawd, dab tsi yog qhov zoo ntawm boron rau cov nroj tsuag?
COMMON BORON FERTILIZERS
| Boron qhov chaw | Formula | Kev sib xyaw |
|---|---|---|
| Borax | Na2B4O7 · 10H2O | 11% B |
| Boric acid | H3BO 3 | 17.5% B |
| Solubor | Na2B8O13·4H2O | 20% B |
Kuj Paub, koj ua li cas kho boron deficiency hauv cov nroj tsuag? Kev kho mob. Boric acid (16.5%) boron borax (11.3%) boron ) los yog Solubor (20.5% boron ) tuaj yeem siv rau cov av kom raug boron tsis muaj peev xwm . Hom kev siv ntawm qhov tseeb boron yog hais txog 1.1 kg / hectar los yog 1.0 lb / acre tab sis qib siab ntawm boron sib txawv nrog cog hom.
Ua raws li qhov no, koj yuav siv boron li cas rau hauv av?
Qhov tseeb boron yuav tsum tau kho tej yam av qhov tsis txaus yog tsawg li 1/2 rau 1 ounce ib 1,000 square feet. Thov qhov pom zoo boron mus rau av , thiab dej qhov chaw txav mus los boron mus rau hauv paus cheeb tsam. Hnav khaub ncaws tiv thaiv, nrog rau cov looj tsom iav, thiab ntxuav kom zoo nrog xab npum thiab dej tom qab thov tus boron.
Dab tsi ua rau boron deficiency?
Boron (B) yog cais raws li ib tug immobile keeb nyob rau hauv cov nroj tsuag. Cov xwm txheej uas tuaj yeem ua rau boron deficiency suav nrog qis boron hauv dej los yog chiv; calcium ntau ntau (uas tuaj yeem cuam tshuam boron txhawb nqa); inactive keeb kwm (dej los yog qhuav av, txias hauv paus cheeb tsam); high humidity; av ntim nruj heev; los yog pH siab.
