01 Dab tsi yog qhov thib ob thiab micro- cov chiv chiv? Cov as-ham no suav nrog cov ntsiab lus thib ob (calcium, magnesium, thiab sulfur) thiab kab kawm (xws li zinc, boron, hlau, manganese, tooj liab, thiab molybdenum). Lawv ua zoo li "vitamin" rau cov qoob loo; thaum qhov xav tau kom muaj tsawg tsawg, qhov tsis txaus ntawm ib qho ntawm lawv tuaj yeem ua rau muaj teeb meem.

Piv txwv li, boron ncaj qha cuam tshuam cov qoob loo flowering thiab fruiting; Qhov tsis txaus tuaj yeem ua rau cov nroj tsuag rapeseed tsim paj tab sis ua tsis tau cov txiv hmab txiv ntoo, thiab ua rau cov txiv hmab txiv ntoo tsis zoo. Zinc cuam tshuam cov synthesis ntawm cov nroj tsuag auxins; tsis muaj zinc tuaj yeem ua rau "albino seedlings" hauv pob kws. Calcium yog ib feem ntawm cov phab ntsa ntawm tes; ib qho tsis muaj peev xwm ua rau paj tawg - kawg rot hauv txiv lws suav thiab "lub plawv qhuav" (tipburn) hauv Suav cabbage.

Cov lus nug tam sim no tshwm sim: yog vim li cas thiaj li muaj kev xav tau ntxiv rau cov ntsiab lus thib ob thiab kab? Qhov no feem ntau yog vim lub sijhawm ntev -, kev siv nitrogen ntau dhau, phosphorus, thiab potassium chiv, uas ua rau cov ntsiab lus no tau sai sai ntawm cov av yam tsis tau rov ua dua.

02 Koj tuaj yeem qhia tau li cas tias cov qoob loo tsis txaus? Qhov tseeb tshaj plaws los txiav txim qhov tsis txaus yog los ntawm kev sim av; Txawm li cas los xij, cov neeg ua liaj ua teb zoo tib yam kuj tuaj yeem ntsuas qhov xwm txheej los ntawm kev soj ntsuam cov qoob loo loj hlob.

Thaum koj pom cov tsos mob txawv txav hauv koj cov qoob loo, koj yuav tsum tau ceeb toom: Puas yog nplooj daj, deformed, lossis pom? Puas yog lub ntsiab lus loj hlob underdeveloped? Puas yog cov txiv hmab txiv ntoo misshapen los yog pom cov pob txha necrotic?

Cov tsos mob ntawm cov zaub mov tsis txaus sib txawv tshwm sim hauv txoj kev sib txawv. Piv txwv li, hlau tsis muaj peev xwm ua rau cov nplooj tshiab ntawm cov qoob loo tig daj thaum cov hlab ntsha tseem ntsuab; zinc deficiency ua rau luv luv internodes thiab nplooj me me; thiab molybdenum deficiency cuam tshuam rau hauv paus nodule tsim nyob rau hauv leguminous qoob loo.

Lwm txoj hauv kev ua tau zoo yog ua qhov me me - ntsuas kev sib piv: xaiv ib ntu me me ntawm daim teb rau kev siv cov chiv uas muaj cov khoom nruab nrab thiab micro- cov zaub mov thaum tawm hauv qhov seem tsis kho, tom qab ntawd sib piv cov qoob loo loj hlob thiab tawm los.

03 Cov Txheej Txheem rau Kev Siv Tau Zoo ntawm Kev Pabcuam Thib Ob thiab Micro- cov khoom noj - Daim Ntawv Thov av: Lub hauv paus ruaj khov rau kev tswj tau yooj yim dua tom qab. Daim ntawv thov av yog thawj txoj hauv kev ntxiv rau cov khoom nruab nrab thiab micro- cov zaub mov. Qhov zoo tshaj plaws, ua ntej sowing los yog transplanting, sib tov cov micro- cov zaub mov kom zoo nrog decomposed organic chiv los yog me ntsis moist av, thiab siv cov sib tov rau hauv furrows los yog cog qhov nrog rau basal chiv.

Tus nqi thov yog qhov tseem ceeb; Tus nqi ntawm cov kab mob chiv siv rau ib mu feem ntau yog tsawg heev: 1-2 kg / mu rau zinc sulfate thiab 0.5-1 kg / mu rau borax. Txawm hais tias qhov ntau npaum li cas yuav nce me ntsis rau cov txiv ntoo thiab zaub, nws feem ntau yuav tsum tsis txhob ntau tshaj 3-5 kg / mu. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias feem ntau cov kab mob chiv yuav tsum tsis txhob tov ncaj qha nrog phosphate chiv, vim tias lawv tuaj yeem tsim cov tshuaj insoluble uas sib koom ua ke txo cov chiv zoo.

Foliar spraying: kho sai nrog cov txiaj ntsig tam sim. Thaum cov qoob loo twb pom cov tsos mob ntawm cov as-ham tsis txaus, foliar txau yog txoj kev kho sai tshaj plaws. Nplooj nqus cov as-ham sai dua li cov hauv paus hniav, ua cov txheej txheem no zoo tagnrho rau kev ntxiv cov as-ham sai sai thaum lub sijhawm loj hlob tseem ceeb. Cov tshuaj tsuag yuav tsum tau tswj nruj me ntsis: 0.05% -0.25% rau boric acid lossis borax, 0.02% -0.05% rau ammonium molybdate, thiab 0.01% -0.02% rau tooj liab sulfate.

Kev kho cov noob yog ib qho nqi-txoj kev zoo los xyuas kom meej qhov sib xws thiab muaj zog yub tshwm sim, tshwj xeeb tshaj yog rau kev siv qee yam kab. Piv txwv li, txheej cov noob txiv laum huab xeeb nrog ammonium molybdate (ntawm tus nqi ntawm 15 grams ib mu) los yog kho cov noob txiv ntoo nrog *Rhizobium* inoculants tuaj yeem txhim kho nitrogen-fixation efficiency. Noob soaking yog lwm txoj kev; soaking txiv laum huab xeeb hauv cov tshuaj ferrous sulfate rau 4 mus rau 5 teev tuaj yeem tiv thaiv tsis muaj hlau.

04 Khaws cov ntsiab lus no hauv siab thaum thov kom tsis txhob muaj teeb meem tshwm sim. Qhov tseem ceeb tshaj, zam dhau - daim ntawv thov. Cov npoo ntawm qhov tsis muaj peev xwm thiab toxicity rau cov kab lus yog nqaim; txawm me ntsis carelessness tuaj yeem ua rau chiv hlawv. Ua tib zoo saib xyuas kev sib raug zoo thaum sib xyaw cov khoom; Tsis txhob sib xyaw cov tshuaj micronutrient chiv nrog cov tshuaj tua kab alkaline lossis tshuaj chiv, vim qhov no tuaj yeem txo qhov ua tau zoo. Kev txhim kho av ib puag ncig yog qhov tseem ceeb. Qhov tsis zoo hauv cov ntsiab lus thib ob thiab kab mob feem ntau tsis yog los ntawm cov ntsiab lus ntawm cov av tsawg, tab sis los ntawm cov ntsiab lus tau "tso" thiab yog li muaj bioavailability tsawg. Kev txhim kho av lub cev thiab tshuaj lom neeg cov khoom- xws li los ntawm kev siv cov chiv chiv los yog cov av txias- tuaj yeem txhim kho qhov muaj ntawm cov khoom no.

Tailor fertilization rau cov qoob loo tshwj xeeb. Cov qoob loo sib txawv muaj qhov sib txawv ntawm cov kev xav tau ntawm cov khoom nruab nrab thiab cov micronutrients: pob kws thiab nplej yog cov rhiab heev rau zinc; rapeseed thiab paj rwb yog rhiab heev rau boron; thiab legumes yog rhiab heev rau molybdenum thiab hlau. Cov chiv uas muaj cov as-ham no ua haujlwm zoo li "cov rog tshwj xeeb" rau koj cov qoob loo-thaum cov khoom siv me me, lawv qhov cuam tshuam tseem ceeb heev. Los ntawm kev ua raws li cov hauv paus ntsiab lus ntawm kev siv tus nqi tsim nyog thaum lub sijhawm los hais txog cov kev xav tau tshwj xeeb, koj tuaj yeem ua kom rov qab los ntawm koj cov peev txheej chiv. Lwm zaus koj fertilize, siv sij hawm ib pliag kom paub meej tias koj cov qoob loo tsis muaj dab tsi ua ntej xaiv cov chiv tsim nyog thiab daim ntawv thov. Kev siv cov chiv chiv theem nrab thiab micronutrient zoo yuav ua rau cov qoob loo muaj zog ntau dua, txhim kho kab mob tiv thaiv, thiab txhim kho tseem ceeb ntawm kev tawm los thiab zoo.
