Yuav ua li cas fertilize zaub off-season nyob rau hauv greenhouses
Kev siv cov tsev cog khoom cog qoob loo rau lub caij nplooj ntoo hlav yog qhov txawv ntawm kev cog qoob loo los yog kev cog qoob loo raws caij nyoog, thiab yuav tsum muaj ntau dua tsev cog khoom ib puag ncig thiab kev tswj hwm cov tswv yim. Hauv tsab xov xwm no, peb tsuas yog piav qhia txog cov ntsiab lus tseem ceeb ntawm fertilization rau off-season zaub cog hauv tsev cog khoom.
1. Xaiv hom chiv zoo:
Fertilize raws li hom zaub. Cucumbers, peppers, txiv lws suav thiab lwm yam melon thiab txiv hmab txiv ntoo zaub, ntxiv rau nitrogen chiv, kuj muaj ib tug loj thov rau phosphorus thiab poov tshuaj chiv. Lub hauv paus chiv yuav tsum yog cov chiv sib xyaw nrog cov khoom noj sib npaug, thiab nws yuav tsum tau ua ke nrog cov chiv chiv.
Siv cov organic chiv ntau dua. Kev siv cov chiv tsis tuaj yeem tsuas yog txhim kho av lub cev, tshuaj lom neeg thiab cov yam ntxwv lom neeg, cov av ripen, fertilize av, txhim kho cov khoom zoo, txo nitrate thiab nitrite cov ntsiab lus hauv zaub, nce vitamin C cov ntsiab lus, thiab nce qab zib cov ntsiab lus hauv txiv hmab txiv ntoo thiab zaub. Daim ntawv thov ntawm cov organic chiv yuav tsum tau decomposed, tshwj xeeb tshaj yog qaib manure, uas yuav tsum tau ib tug high degree ntawm decompression thiab yuav tsum tau thov ua ntej.
2. Txiav txim siab qhov nyiaj txiag fertilization
Lub hauv paus ntawm kev txiav txim siab kev lag luam fertilization tus nqi kom tau raws li cov zaub xav tau yuav tsum tau xam raws li qib zaub yield thiab av fertility. Yog hais tias cov nitrogen, phosphorus thiab potassium nutrient mov ntawm cov av tuaj yeem ua tau raws li cov kev xav tau ntawm cov qoob loo, tus nqi fertilization yuav tsum raug xam raws li 20 feem pua -40 feem pua ntawm cov qoob loo nqa mus rau kev siv chiv. Nyob rau theem tam sim no ntawm fertility, tswj nitrogen, txo phosphorus, poov tshuaj stabilization, thiab tsom daim ntawv thov ntawm micro-fertilizers yuav tsum yog cov hauv paus ntsiab lus ntawm fertilization.
3. Xaiv hom chiv
Feem ntau, chlorine-raws li chiv, xws li potassium chloride thiab ammonium chloride, yuav tsum tsis txhob siv. Chloride ions tuaj yeem txo cov hmoov txhuv nplej siab hauv zaub thiab ua kom tsis zoo, thiab cov khoom seem hauv av tuaj yeem ua rau cov av compaction. Nws tsis raug nquahu kom siv cov chiv nitrogen tsis hloov pauv, xws li ammonium nitrate, ammonium bicarbonate thiab lwm yam chiv nitrogen. Yog tias siv, nws yog qhov zoo tshaj rau qhib ditches thiab thov lawv tob rau hauv cov av.
