Yuav cog txiv lws suav hauv tsev cog khoom li cas?

1. Kev xaiv noob

Xaiv ntau yam nrog cov kab mob muaj zog tiv thaiv, muaj zog tiv taus txias, zoo thiab muaj txiaj ntsig zoo, khaws cia thiab kev thauj mus los tsis zoo, tsis muaj teeb pom kev zoo thiab tsim nyog rau kev cog qoob loo. Cov txheej txheem ntawm kev kho cov noob muaj xws li cov noob soaking, kub tshuaj tua kab mob, noob soaking hauv cov kua zaub sov, thiab kev kho cua sov qhuav. Cov noob soaking dej kub yog 50 ~ 52 degree, tsau cov noob nrog 0.2 feem pua ​​~ 0.3 feem pua ​​ntawm cov tshuaj poov tshuaj permanganate, tsau cov noob rau 20 feeb, tshem tawm, yaug thiab qhuav; kub tshuaj tua kab mob yog kho cov noob nrog kub kub kom tua cov kab mob pathogenic txuas rau saum npoo ntawm cov noob; Sov kua zaub Sow Sod yog soaking cov noob nyob rau hauv dej ntawm li 55C rau 30 feeb kom tua cov fungus; Kev kho cua sov qhuav yog hais txog kev kho cua sov ntawm cov noob qhuav (nrog cov dej hauv qab 10 feem pua) hauv qhov cub ntawm 70C rau 72 teev.

2. Cov noob

Seedling chaw: 22-25 mesh kab-pov thawj nets thiab 65 feem pua ​​-75 feem pua ​​​​shading nets yuav tsum tau siv rau seedlings nyob rau hauv lub caij ntuj sov thiab lub caij nplooj zeeg, thiab seedlings nrog ntau tshaj 6 nplooj los yog loj seedlings nrog buds feem ntau yog siv rau yub cov tais nrog 72 qhov lossis 50 qhov. Siv cov yub pov tseg lossis cov tais uas siv tau rov qab, tom kawg yuav tsum tau ua kom tsis muaj menyuam ua ntej. Kev npaj matrix: Qhov piv ntawm matrix yog peat: vermiculite: perlite=3: 1: 1, thiab tus nqi ntawm perlite yuav tsum raug txo kom tsim nyog rau lub caij ntuj sov. Rau kev tua kab mob nrog carbendazim, ntxiv 100 grams ib cubic meter, thiab nyob rau tib lub sij hawm ntxiv 1.4 kilograms ntawm compound fertilizer, los yog tshwj xeeb chiv rau seedlings, 1 kilogram ntawm nitrogen, phosphorus thiab poov tshuaj cov ntsiab lus ntawm 20-20-20. Lub ntsiab lus tseem ceeb ntawm kev npaj matrix yog tias tag nrho cov khoom xyaw zoo sib xyaw thiab sib xyaw. Thaum sowing, lub degree ntawm dryness thiab ntub dej ntawm substrate yog xws li hais tias nws yuav tsum tau tsim nyob rau hauv ib pab pawg neeg los ntawm pinching nws, thiab nws yuav dispersed los ntawm maj mam poking nws tawm.
3. Nplej

Plug seedlings muaj qhov xav tau siab ntawm cov noob, thiab cov noob uas tsis muaj germination tsawg lossis tsis muaj zog yuav tsum tsis txhob siv. Lub substrate yuav tsum tau xoob loaded rau hauv lub tais ntsaws, nruj heev yuav cuam tshuam rau kev loj hlob ntawm seedlings, thiab lub substrate yuav tog tom qab watering yog heev xoob. Qhov tob tob yog li 1 cm, lub substrate yog muab tso rau ntawm ib lub phaj thiab stamped rau sowing, thiab ces lub substrate los yog vermiculite yog them nrog ib tug tuab ntawm 0.5 mus rau 1 cm.

4. Kev tswj cov noob

Lub caij kub kub nyob rau lub caij ntuj sov yog tsuas yog kom txias, tshwj xeeb tshaj yog tiv thaiv kub thaum hmo ntuj. Yog tias muaj qhov kub thiab txias tsis tu ncua thaum hmo ntuj, cov dej noo tuaj yeem tswj tau los tiv thaiv kev loj hlob leggy. Nyob rau lub caij ntuj sov, watering yuav tsum tsis txhob nyob rau yav tav su thiab yav tsaus ntuj, thiab feem ntau yog thaum sawv ntxov. Hmo ntuj kub nyob rau lub caij ntuj no yuav tsum tsis txhob qis dua 14 degree, thiab qhov kub thiab txias yuav tsum tau rhuab kom zoo. Cov yub tuaj yeem ua kom txias kom zoo thiab tswj dej tom qab peb nplooj thiab ib lub siab, thiab cov yub tuaj yeem ua kom tawv, tab sis qhov kub thiab txias tsis tuaj yeem qis dua 10 degree. Tus qauv ntawm caij nplooj ntoos hlav coj mus muag seedlings txawv nyob ntawm seb qhov luaj li cas ntawm lub qhov nyob rau hauv lub plug tais. Cov 72- qhov yub yub lub tais raug xaiv, nrog cov nroj tsuag qhov siab ntawm 18-20 cm, lub qia txoj kab uas hla ntawm 4.5 mm, nplooj nplooj ntawm 90-100 square cm, thiab 6-7 muaj tseeb nplooj thiab me paj buds. , nws yuav siv sij hawm 60-65 hnub ntawm cov noob muaj hnub nyoog; Lub caij ntuj sov seedlings xav tau 20 hnub, cog qhov siab yog 13-15 cm, qia txoj kab uas hla yog 3 hli, thiab nplooj cheeb tsam yog 30-35 square cm.
5. Colonization

Ua ntej kev npaj, basal chiv yuav tsum tau decomposed tag nrho, thiab txoj kev sai decomposing ntawm cov kab mob nquag siv tau. Tom qab cov qoob loo yav dhau los raug rub, lub vaj yuav tsum tau muab ntxuav hauv lub sijhawm thiab lub tsev cog khoom yuav tsum tsis muaj menyuam. Buckling shed roasting yuav tsum tau nqa tawm 15 mus rau 20 hnub ua ntej cog.

6. Colonization

Qhov kub hauv av ntawm 10 cm yog ruaj khov tshaj 10 degree, qhov tsawg kawg nkaus kub yog siab tshaj 6 degree, thiab nws yog ruaj khov rau 5 mus rau 7 hnub tom qab colonization. Kev cog qoob loo sib txawv raws caij nyoog thiab ntau yam thiab los ntawm txoj kev pruning. Ib lub qia pruning tuaj yeem cog kom zoo, nrog rau kab sib nrug ntawm 50 cm thiab cog qhov sib nrug ntawm 30-40 cm. Ob-stem pruning yuav tsum tau tsim nyog thinned. Ntau yam ntxov ntxov tuaj yeem cog tau ze, thiab cov hom nruab nrab thiab lig-loj hlob yog cog me ntsis sparsely.
