Bio txhawb nqa-kev daws teeb meem rau kev ntxhov siab thiab txhim kho qoob loo tawm los

Vim tias muaj kev hloov pauv huab cua, huab cua thiab caij nyoog tau dhau los ua kev tsis paub ntau ntxiv, feem ntau ua rau qoob loo poob. Txheeb xyuas qhia tias 60% mus rau 80% ntawm cov qoob loo sai sai poob yog tshwm sim los ntawm kev siv kev ntxhov siab; Cov qoob loo qoob loo muaj cov huab cua zoo xyoo thiab muaj huab cua tsis zoo. Kev tsim kho me me tuaj yeem ua tau zoo rau cov teeb meem kev ntxhov siab ntxhov siab.

1. Bio-stimulants
Kev txhawb nqa yog ib chav ua yeeb yam thiab cov qauv lossis cov kab mob ua kom zoo, txhawb kev ua tau zoo, txhawb kev siv tau cov zaub mov zoo, thiab cov qoob loo zoo. Lawv cov teebmeem yog cov kev ywj pheej ntawm lawv cov ntsiab lus zoo.

Tam sim no, ntiaj teb pom tau tias poob rau hauv plaub pawg tseem ceeb: cov roj ntsha, cov roj ntsha, polypes thiab cov amino acids, thiab cov kua qaub uas muaj txiaj ntsig dawb. Qee lub koom haum kuj suav nrog Chitosan thiab cov zaub mov.

Cov kev siv hluav taws xob no muaj peb daim ntawv thov tseem ceeb, nyob ntawm lawv cov teebmeem tshwj xeeb thiab kev siv hluav taws xob: kev kho cov roj, lossis daim ntawv thov av.

Nws yog ib qho tseem ceeb kom nco ntsoov tias Bio-stimulants yog tsis cog nroj tsuag kev cai lij choj tsis tshuaj tua kab, tsis yog lawv fertilizers. Lawv tsis tuaj yeem hloov cog cov nroj tsuag cov neeg tswj hwm, tshuaj tua kab, lossis chiv; Lawv yog ib yam dab tsi hauv nruab nrab:

Lawv tsis cog tsob ntoo kev loj hlob regulators, tab sis lawv tuaj yeem ntxias cov nroj tsuag kom tsim cov tshuaj hormones endogenous, txhim kho nws tus kheej kev ntxhov siab tiv taus;

Lawv tsis yog fungicides, tab sis lawv tuaj yeem ntxias cog ua rau cov nroj tsuag fungal, cov kab mob, thiab kab mob kis;

Lawv tsis yog chiv, tab sis lawv tuaj yeem txhim kho cov kev nqus thiab siv cov chiv ntawm cov qoob loo, ua rau muaj cov qoob loo ntau dua thiab cov khoom lag luam ntau dua thiab zoo dua.

Qhov no yog tus yam ntxwv zoo tshaj plaws ntawm bio-stimulants.

2. Siv cov roj ntsha-stimulants

Kev txhawb nqa bio tuaj yeem hais txog kev tsim txom kev ntxhov siab uas tua kab thiab chiv tsis tuaj yeem daws tau. Yog li, yuav ua li cas lawv thiaj siv tau thiab siv tau zoo?

Peb ib txwm hais txog tias daim ntawv thov ntawm biological tshuaj tua kab yuav tsum tsom rau kev tiv thaiv, hloov los ntawm kev tiv thaiv kom siv tau. Tib yam siv rau bio-stimulants. Peb tuaj yeem faib cov kev siv bio-stimulants rau hauv peb theem: kev tiv thaiv, kev kho mob muaj tseeb, thiab kev kho mob. (1) Ua ntej kev ntxhov siab ua ntej kev ntxhov siab muaj tshwm sim (kev tiv thaiv / sensitization theem): Siv biostimulants los txhim kho cov qoob loo kev ntxhov siab.
(2) Thaum lub sijhawm tshwm sim ntawm kev siv phom sij (reactive / bioschlactic kev siv qoob loo ntau ntxiv thiab txhim kho cov qoob loo muaj sia nyob.
(3) Tom qab kev ua phem rau kev ntxhov siab (kho theem): Siv biostimulants los txhim kho cov qoob loo loj hlob thiab kev loj hlob.

Lub hom phiaj kawg yog txhawm rau txhim kho cov qoob loo uas muaj kev cuam tshuam nrog cov qoob loo thiab ua kom lawv muaj kev ntxhov siab zoo dua. Qhov kev sib tw no tseem ua rau txo cov tshuaj tua kab tshuaj tua kab thiab txo cov tshuaj tua tshuaj tua tshuaj tua kab.


2.1 Ua ntej thiab thaum pib siv kev ntxhov siab - kev tiv thaiv thiab qib teb

(1) Kev kho noob noob

Soaking nplej thiab pob kws noob hauv 0.1 ml / l thiab 1.5 m

(2) pre-emptive thov thiab av kho

Nrog kua dej nrog biostimulant tau thov rau cauliflower 21 hnub tom qab hloov pauv. Thaum sau qoob loo, cov txiaj ntsig tau pom tias Biostimulant-kho cov zaub mov muaj ntau dua ntawm 1.15 ntau dua ib hectare (11% nce), thiab rov qab los ntawm kev nqis peev ntawm 16-35 zaug.

Thov biostsimulant ntawm ntau ntawm 0, 6, 12, thiab 25 kg / HMOOG 1, thiab 25 Lub 25 kg / HMOOV ua tau zoo tshaj plaws.

Ob hlis tom qab ob daim ntawv thov ntawm biostimulant, txiv tsawb nroj tsuag tau pom zoo dua kev loj hlob piv rau cov pab pawg tswj.

(3) Cov Kev Txau Foliar

Qos nroj tsuag tau txau nrog 4.5 l / HM² ntawm BIostimulant 5 hnub ua ntej muaj kev ntxhov siab txias. Cov nroj tsuag muaj dhau los 60 hnub ntawm kev ntxhov siab txias (suav nrog 6 cov xwm txheej te, nrog qhov tsawg kawg ntawm -3.6 ° C). Thaum sau qoob, cov biostimulant-kho cov qos yaj ywm pom muaj cov tawm tsam ntau dua, loj dua tuber loj, thiab ntau dua cov tubers.

Xaus Lus: Txawm siv los ntawm kev kho cov noob, daim ntawv thov av, lossis rov qab ua kom muaj kev puas tsuaj rau cov qoob loo, thiab txo cov txiaj ntsig sai sai thaum lub sijhawm thiab ua ntej kev siv phom sij.

2.2 Tom qab kev cuam tshuam kev ntxhov siab - kev kho theem

Tom qab lawg ua kev puas tsuaj rau pob kws nroj tsuag loj hlob nyob rau hauv saline av, ib foliar thov ntawm 3 l / h "ntawm ib tug biostimulant yog tus neeg thov. Thaum sau, tawm tau raug ntsuas: piv rau kev tswj hwm, kho cov pob kws muaj cov khoom lag luam ntau dua rau ib tsob ntoo) thiab cov khoom lag luam siab dua.

Thaum lub sij hawm ntuj qhuav heev nyob hauv Tebchaws Europe, qos ntoo nyob ntawm cov liaj teb yam tsis muaj dej khov kho kev ntxhov siab. Peb daim foliar cov ntawv thov ntawm 3 l / his ntawm biostimulant txhim kho cog kev noj qab haus huv, ua rau cov lus siab dua thaum sau qoob loo.

Cov kev sim no qhia tau tias biostimulants muaj peev xwm txo qhov kev cuam tshuam ntawm kev ua phem rau kev ntxhov siab ntawm cov qoob loo. Kev tsom xam cov ntaub ntawv ntau yam qhia tau tias kev siv biostimulants thaum 17%, piv rau kev ntxhov siab thiab tsuas yog 8% tom qab kev ntxhov siab.

Yog li ntawd, qhov xaus yog tias siv biostimulants ua ntej kev ntxhov siab (raws li kev tiv thaiv kev ntsuas) muaj txiaj ntsig zoo dua. Qhov no ua tau txiaj ntsig zoo ntawm cov txiaj ntsig ntawm biostimulants thiab minimizes qhov cuam tshuam tsis zoo ntawm kev ntxhov siab ntawm cov qoob loo tawm.

Cov kev sim ua ntej tau lees paub qhov xaus no. Piv rau kev tswj hwm, kev thov biostimulant raws li kev tiv thaiv kev ntsuas ntau dua los ntawm 12,8%, thaum daim ntawv thov tom qab tau nce tawm los ntawm 7.3%.
