盆栽植物叶子发黄是什么原因?

盆栽植物在我们日常生活中很常见,经常见到盆栽植物叶子发黄,这是什么原因呢?那今天我们山东绿化苗木

Plants in our daily life is very common, often seen in the leaves of potted plants yellow, which is why? That today we Shandong green seedlings small series to introduce you to:

盆栽植物应该适量浇水,坚持“见干见湿,浇则浇透”的原则,如给盆栽植物浇水过多,容易造成盆土长期水大,使根部窒息腐烂,不能正常吸收水分,从而导致盆栽植物黄页甚至脱落。如发现黄叶应停止浇水,疏松土壤,让其通风干燥。

Potted plants should be regular watering, adhere to the principle of "see dry see wet, irrigate irrigate through. As for watering potted plants too much, easy to cause the basin soil for water. The roots of asphyxia decay, does not absorb moisture, resulting in potted plants in the yellow pages or even fall off. That leaves should stop watering, loose soil, let it dry and ventilated.

施肥不当:在盆花生长期,长期不施肥或施肥不足等,会引起叶黄现象;施浓肥过多,花吸收不了把根烧伤,不能吸收水分同样会引起叶黄凋落,夏季每周施一次稀薄肥,切勿多施浓肥。若施肥过多,可多浇水稀释并冲去土壤中肥分。缺肥时可导致盆土板结,花叶黄、薄、瘦,枝条细长黄嫩。应立即施肥,一周内见效,可按期施肥,使花正常生长,开花多。

Improper fertilization: for a long time in the basin of peanut, long-term no fertilization or fertilizer is insufficient, cause leaf yellowing phenomenon; Shi concentrated fertilizer too many flowers can not absorb the root burn, cannot absorb all the water will also cause the yellow leaves fall, a week in summer Shi a thin fat, never apply more concentrated fertilizer. If too much fertilizer, can be more water diluted and rushed to the soil fertilizer. Lack of fertilizer can result in pot soil compaction, flower and leaf yellow, thin, thin, slender yellow and tender branches. Immediately fertilization, within a week of work, regular fertilization, the normal growth of flowers, flowers blooming.

Water shortage: flowers, such as water shortage, should immediately go to the water spray, to speed up the absorption of plants to water, and then to the pot of water, then pay attention to less water so that soil moisture can be, not to water.

Temperature is too high: in the summer high temperature season, likes the cool resistant female flowers in light and high temperature, according to the strength, extremely easy to cause leaf tip or leaf edges scorched, encounter this kind of to timely transfer to sunshading and ventilating place, water cooling, increase humidity favorable flower growth.

Flower bowl: due to spend a large root system, fertilizer, small basin can not meet the flower grows need, when the old leaves often dry yellow dull, leaves thin, yellow, it is necessary to change the appropriate basin, soil to add 3% humus soil and the flowers grew normally.

Branches and leaves a secret: the growth of branches and leaves, lush and not long after pruning, Chido Mieyokoteru insufficient, appear yellow leaf shedding phenomenon, should strengthen pruning ventilate the cella and proper fertilization.

Insufficient light: like sun flowers, such as rose, pomegranate long placed in the light too weak, it will make the plants gradually weak, thin and yellow leaves, flowers or less flowering.

Chill: because the spring flowers out of the room early by the cold, or the autumn cold, freezing injury and yellow leaves, burglary, insulation and advance cold acclimation of potted flowers flowers.

病虫危害:受到花叶病毒侵染后叶面上多现黄绿相嵌的斑块,受到真菌等病菌侵染而引起叶斑病,易使叶片局部坏死,应注意预防病害,及时喷药并给予充足的光照和通风。在夏季高温季节易产生虫害,要喷药预防,一般有蚜虫、红蜘蛛等,在叶背吸取营养和水分,使叶面枯黄甚至全株叶子萎黄脱落,及时灭虫可恢复。

Plant diseases and insect pests: by mosaic virus infection after foliar show more yellow green inlaid plaques by fungus pathogen infection caused by leaf spot disease, easy to make the blade local necrosis, should pay attention to the prevention of disease and spraying in time and give adequate light and ventilation. High temperature in summer season is easy to produce the pest, the spraying prevention, aphid, red spider, on the back of leaf and absorb nutrients and moisture, make the leaf withered and yellow or even whole plant Chlorosis on the leaves off, timely pest control can be restored.

其他:花卉在受到大气中有毒气体毒害,或者气温高时突然浇冷水会造成生理干旱,喷高浓度农药防治病虫害时,均会引起叶尖或叶面局部焦枯,甚至全株死亡,因此要注意排除空气污染源,或栽植抗污染植物,合理使用农药,炎热夏天在上午10时前,下午4时后浇水为宜。

Other: flower in the toxicity of toxic gases in the atmosphere, or high temperature suddenly poured cold water will cause physiological drought, spraying high concentration of pesticides to control pests and diseases will cause tip or foliar local scorch, even the death of the whole plant. Therefore, in order to pay attention to the exclusion of air pollution source, or anti pollution plant planting, rational use of pesticides, hot summer before 10 o'clock in the morning afternoon 4 when watering is appropriate.
