dej zaub cas dej zaub watering precautions
Vim li cas dej zaub
Los ntawm kev tshawb fawb pom, cov nroj tsuag tuaj yeem loj hlob yam tsis muaj tshuaj chiv thiab tshuaj tua kab, tab sis lawv yuav tsum muaj dej. Thaum dej yog absorbed los ntawm lub hauv paus system, nws kuj nqa cov qoob loo loj hlob
Tom qab ntawd cov macronutrients raug thauj mus rau stems thiab txiv hmab txiv ntoo. Ib txhia ntawm lawv poob los ntawm transpiration ntawm nplooj, thiab lwm qhov yuav ploj los ntawm photosynthesis ntawm nplooj thiab stems.
hloov mus rau hauv cov as-ham.
Yuav ua li cas qhia yog tias zaub xav tau dej
1. Txiav txim seb puas yuav dej raws li cov av noo noo
Cov hauv paus zaub ncaj qha nqus dej los ntawm cov av, thiab cov dej hauv av ncaj qha cuam tshuam rau kev nqus ntawm cov hauv paus hniav. Yog li ntawd, watering tuaj yeem txiav txim los ntawm cov av noo noo. - Feem ntau, siv 10 cm tob av. Yog tias koj tuav nws rau hauv ib lub pob, muab tso rau ntawm lub duav thiab nthuav tawm rau hauv av, qhia tias cov ntsiab lus noo noo yog qhov tsim nyog thiab tsis tas yuav tsum tau ywg dej; yog tias cov av tsis tuaj yeem tuav tau rau hauv ib lub pob, nws qhia tau hais tias cov av tsis muaj dej thiab yuav tsum tau watered; yog tias dej tuav, nws yuav poob rau hauv av Yog tias nws tsis tawg, txhais tau hais tias cov av yog dej heev thiab tsis xav tau dej.
2. Txiav txim seb puas yuav dej raws li kev loj hlob ntawm cov zaub
(1) Noob germination theem: dej txaus yuav tsum tau rau cov noob nqus dej kom nthuav, txhawb germination thiab elongation ntawm hypocotyl. Lub sij hawm no yuav tsum tau irrigated los yog sown thaum cov av noo noo zoo.
(2) Seedling theem: nplooj nplooj ntawm cov nroj tsuag yog me me, tus nqi ntawm transpiration yog me me, thiab cov dej yuav tsum tau tsis ntau, tab sis lub faib ntawm lub hauv paus pab pawg neeg yog ntiav, thiab nws yog yooj yim cuam tshuam los ntawm drought. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tswj hwm cov av noo hauv kev cog qoob loo.
(3) Kev loj hlob ntawm kev loj hlob thiab lub sij hawm tsim khoom noj khoom haus: lub sij hawm nrog cov dej xav tau tshaj plaws. Kev saib xyuas yuav tsum tsis txhob muab dej ntau dhau thaum cov khoom noj khoom haus reservoir pib tsim, txhawm rau inhibit qhov kev loj hlob ntawm stems thiab nplooj thiab txhawb kev tsim cov khoom hauv nruab nrog cev. Thaum nkag mus rau lub sijhawm siab tshaj plaws ntawm cov khoom hauv nruab nrog cev, nws yuav tsum tau watered nquag.
(4) flowering thiab fruiting lub sij hawm: flowering thiab fruiting yuav tsum nruj me ntsis rau dej, dej ntau dhau, yooj yim ua rau stems thiab nplooj loj hlob leggy thiab ua paj thiab txiv hmab txiv ntoo; Cov dej tsawg dhau, cov dej hauv cov nroj tsuag tau rov faib dua, thiab cov dej yog absorbed los ntawm qhov chaw uas muaj dej tsawg dua (xws li cov tub ntxhais hluas tua, cov tub ntxhais hluas cov hauv paus hniav, thiab lwm yam) yuav ntws mus rau hauv cov nplooj uas muaj zog nqus dej, uas tseem yuav ua rau cov nroj tsuag muaj zog. paj thiab txiv hmab txiv ntoo poob. Yog li ntawd, irrigation yuav tsum tau tswj kom zoo thaum lub sij hawm flowering lub sij hawm. Tom qab nkag mus rau lub sijhawm tshwm sim. Tshwj xeeb tshaj yog nyob rau lub sij hawm txiv hmab txiv ntoo expansion los yog lub sij hawm fruiting, cov dej thov nce sharply thiab mus txog qhov siab tshaj plaws tus nqi. Cov dej txaus yuav tsum tau muab los ua kom cov txiv hmab txiv ntoo nthuav dav thiab loj hlob sai.
3. Irrigation raws li huab cua yam ntxwv
Txij lub Peb Hlis mus txog rau Lub Rau Hli, qhov kub ntawm sab nraud yuav maj mam nce, lub teeb yuav nce ntxiv, kev loj hlob ntawm cov zaub yuav nce ntxiv, thiab cov qoob loo yuav nce ntxiv. Thaum lub sij hawm no, tus nqi ntawm cov dej yuav tsum tau maj mam nce, tab sis tus nqi ntawm cov dej yuav tsum tsis txhob loj heev. Yog tias siv drip irrigation technology, nws yuav tsum tau tswj ntawm Txog 8 square acres txhua zaus.
From June to September, the cultivation in the protected area is mainly rain-proof and cooling cultivation, and the irrigation should be determined according to the rainfall. If there is a lot of rain and the air humidity is high, it should be irrigated less, and at the same time, waterlogging and drainage should be prevented; if there is little rain and the weather is dry, the number of irrigation times and the amount of irrigation should be appropriately increased, so as to meet the water demand of vegetables while reducing the ground temperature and promoting vegetable production.
Zaub loj hlob. .
Pib txij thaum nruab nrab Lub Cuaj Hli, kev cog qoob loo cog qoob loo yog tswj hwm los ntawm thaj chaw tiv thaiv, thiab sab nraud kub pib maj mam poob. Raws li kev loj hlob ntawm cov qoob loo thiab huab cua puag, tus nqi ntawm irrigation yuav tsum maj mam txo.
