Problem advocate camellia is raised work is good, shu Lei reachs the designated position, rectify what body length situation has been in to be able to accuse limits inside. Symptom of this tea lamina agrees with Mr. Huang Jingzhai to analyse.
Is the leaf dry edge that you ask to bask in injury or go to the bad? Because this kind of phenomenon is common, not be ill to me. How to say? Say disease does not make disease namely, blame disease has hidden trouble however.
Come to bask in injury or infection of go to the bad then? Accurate saying is not to be basked in, but with heat (temperature is concerned) . But the root that do not have an injury, it is foliaceous watch only.
Graphic: Red circle brown of predestined relationship of 1 lamina leaf is withered have weather-shack, but place of speckle brim apophysis has mark of corrupt of apparent yellow water, apparent two kinds. See green arrowhead is in.
Pink encircles 2 leaves predestined relationship is red circle the symptom before 1 lamina pathological changes, namely does 2 leaves predestined relationship develop pink later period namely red? ? 1 lamina now symptom. Pink encircles green arrowhead to indicate place, yellow is begin pathological change, black is already changed, come on this disease the rule appears entirely come out.
Graphic 2: Red circle 2 Alexandrine, 1 apex does La Juan a bit pointed, this is root system has bit of uncomfortable show a bit.
Inscribe so far advocate place of camellia lamina symptom shows a problem to already was decomposed end. A word, this phenomenon basically is cause by high temperature and damp and hot, origin or environment are ventilated problem.
Old observation comes down, room of central heating of this phenomenon winter, although Nanyang stage is proper ventilated, because winter is dry,meet blade gush water. When I discover blade gush water, be about the window is ventilated, as long as ventilated do not reach the designated position or frequency of blade gush water adds high temperature too much dry, can appear this problem.
Manage together, summertime high temperature is high wet season, although indoor and round-the-clock a window is ventilated, want a basin only under window plane, indoor blame north and south to convection wind, blade also can appear this phenomenon.
Pathogeny basin earth waters overmuch, blade gush water is overmuch. Root system is bibulous full after closing, ventilated do not reach the designated position, blade rising fast be less than water portion to supply fast when, receive high temperature strong light, especially the summer midday that paragraph, blade evaporates because of water portion slow, water portion is supplied excessive when increase part of a historical period of tall wet broil, cause yellow corrupt of sex of water be soiled, root system of the imply when blade Huang Futong suffers a bacterium to invade and have unwell, root system is unwell express do a needle namely through Xie Jian.
Origin of all pathological changes is solved, say to improve finally: This phenomenon is not ill. Enhance land of ventilated and loose basin can. To earth up of upside of root system of the indoor proposal that raise tea with thin had better, conduce to basin land root system coming loose wet. Root system can breathe freely to be able to reduce an odds of wet sodden root.
Basin earth should do dry wet loop, "Dry see the flower is wet see a part of a historical period " explained the marrow that raise a flower. Root Mi is fighting the ability in wet loop environment only good growth, reduce hidden danger.
Blade can use Mi bright amine to control. The proposal does next basin earth worm. Harrass of damp and hot of high temperature of estivate of root system classics, conceal have conceal fungus, had better do next antiseptic mulch had better.
Like to fall rain says the flower nods attention.
