2. Scorched npoo ntawm cov nplooj laus - Potassium deficiency spasm - Cov tsos mob: Nplooj nplooj tshwm scorched, maj withering inwards - Ua rau: Ntev - lub sij hawm siv nitrogen chiv (xws li urea) - Kev kho mob xwm txheej ceev: Txau nrog ntoo tshauv leachate (1:50) ob zaug ib hlis.

3. Daj -cov kab txaij ntsuab ntawm nplooj - Magnesium deficiency malnutrition - Cov tsos mob: Cov kab txaij daj tshwm ntawm nplooj nplooj, zoo li kab txaij zebra.

- Ua rau: Cov av acidic yog qhov ua rau tsis muaj magnesium (ntau nyob rau yav qab teb cheeb tsam) - Kev kho mob xwm txheej ceev: Siv tshuaj magnesium sulfate (1:1500) peb zaug sib law liag.

Qhov "invisible killer" tom qab qhov chaw

1. Cov kab xeb xeb ntawm nplooj - Zinc deficiency ntawm daim tawv nqaij kab mob - Cov tsos mob: daj- xim av tshwm ntawm nplooj, nplooj tshiab deformed - Ua rau: Ntev- siv lub sij hawm siv uncomposted organic chiv - Kev kho mob xwm txheej ceev: Txau nrog zinc sulfate tov (1: 2000) txiv neej ua ke nrog zinc sulfate (1: 2000).

2. Dawb, scorched nplooj nplooj - Boron deficiency metabolic teeb meem - Cov tsos mob: Whitening ntawm nplooj npoo, necrosis ntawm qhov loj hlob point - Ua rau: Boron deficiency nyob rau hauv cov av (xws li, xuab zeb av) - Kev kho mob xwm txheej ceev: Drench cov cag nrog ib tug borax tov (1:2500), tsom rau hauv paus cheeb tsam.

Ib qho teeb meem kev nyuaj siab los ntawm kev loj hlob tsis zoo

1. Twisted thiab withered tshiab tua – Calcium deficiency rickets - Cov tsos mob: Terminal buds tuag, nplooj tshiab curl zoo li qaib taw - Ua rau: Ntev- lub sij hawm watering nrog purified dej (tsis muaj minerals) - Kev kho mob thaum muaj xwm ceev: Siv cov hmoov nplej hmoov calcium (% chloride) los yog tshuaj 3.

2. Small and brittle leaves – Copper deficiency stunting – Symptoms: Thin leaves, easily broken, leaf edges curling inward – Cause: Soil pH too high (>7.5) - Kev kho mob xwm txheej ceev: Siv cov tshuaj tooj liab sulfate (1: 3000) ua ke nrog humic acid
