There are many reasons for the yellowing of the leaves of the rich tree. If it is caused by water shortage, it will increase the watering. If it is caused by too much watering, it will reduce the watering. If the light is too strong, it will reduce the light. If it is lack of fertilizer, it will increase the amount. Fertilizer, if it grows too lush, it will pruning and cutting leaves.

Reason one: improper watering

Rich trees like a warm and humid climate, too much or too little water will cause the leaves to yellow. Too much watering, the soil in the basin is often too wet, the roots of the tree are not smooth, the roots rot, and then gradually spread to the branches, and finally the leaves turn yellow, withered and shed, and the whole plant dies when severe. If the watering is too little, the soil on the potting soil will be dry and dry, which will not only affect the absorption of nutrients, but also cause the leaves to be dull and dull, and gradually fade from the bottom to the top, and the tree will be silently protesting against your laziness~

Solution: ventilate, turn basin or hydrate in time. When there is too much water, put it on the window and do a good job of ventilation. If the potting soil cannot be dried in a short time and it is muddy, you can put a layer of absorbent cotton cloth on the bottom of the flower pot. If it is wet, it will be replaced with a new one, or blow it with a fan. If you use all the methods and the soil does not dry out, then change the soil.

When the watering is too small, the surface of the soil is cracked, and in the case of not all yellowing, the hydration is gradually performed. Wet the surface of the soil first, pour a little one hour, and gradually pour water. Avoid watering the water at one time to prevent the roots from swelling and affecting growth.

Reason 2: Improper lighting

xx The fortune tree likes the sun, but it is not resistant to direct sunlight. The sun or the long-term shade will also cause the leaves to be yellow. Putting the fortune tree in the corner of the room, paying too much attention to the viewing effect, causing the rich tree to be in a shaded environment for a long time, will cause the new leaves to grow yellow and long, the old leaves are dull and a lot of falling off. Summer is hot, you can only blow air in the house, how can the rich tree survive the impact of the sun. If you forget to move it to the shaded place at noon, you can only accept the yellowing of the leaves.

Solution: Move to the semi-shade. For the sudden acceptance of the sun, resulting in the yellowing of the leaves of the rich tree, the chance of saving is not great. The leaves are yellow due to excessive exposure, and the moisture of the leaves is highly volatile. It is difficult to recover in a short time. It is recommended to move to the semi-shade. Appropriate watering, yellowing leaves will slowly fall off, to grow sprouts.

Reason three: too much fertilizer

You must be afraid of the rich tree, the lack of fertilizer to become malnourished, right? But excessive fertilization is not good either. The nutrients absorbed by the rich tree are quantitative. If the fertilizer is excessively applied and the plant absorbs sufficient nutrients, the remaining fertilizer will burn the roots of the tree, which will cause the leaves to yellow.

Solution: Rooting and changing soil. Too much fertilization leads to the decay of the roots of the tree, the plants are removed, the decayed parts are cleaned, replaced with new soil, and replanted. Or by watering, dilute the nutrients in the soil and reduce the fertility.

Reason four: temperature is not

Some people hate summer and winter, because a temperature is too high, a temperature is too low, in fact, plants are also like this, the suitable temperature for the growth of rich trees is 20 ° C ~ 30 ° C, too high or too low will affect its growth. If the temperature in the growing environment of the rich tree is too high, the transpiration is too strong, the water and nutrient supply in the roots are insufficient, and the leaves will gradually dry and yellow. However, if the temperature is too low, for example, if the temperature in winter is lower than 16 °C, the leaves will easily yellow and fall off, and it will easily die below 10 °C.

xx 解决方案:提高温度。在夏季,由于高温,树木的黄叶被制成,植物及时移动到阴影处,水被冷却。如果黄变不严重,它将慢慢恢复生长。在冬季,适当提高固化温度,以避免冻伤。

原因5:病虫害

幸运树被真菌和细菌侵染,导致叶斑病,叶片局部坏死,导致黄斑或斑点。在严重的情况下,整件是黄色和下降。不仅是细菌,还有许多害虫,如红蜘蛛和鳞虫,都会导致丰富树木叶片的黄叶。仔细看。

解决方案:喷药。加强通风,及时喷药。对于不同的病虫害,选择相应的杀菌剂,每5至7天喷一次,并喷洒3至4次即可。 (推荐药:多菌灵,百菌清,花保护神)

原因六:叶子太密集了

生长树具有很强的生长能力,树枝和叶子生长旺盛。如果你没有经常修剪的习惯,由于光线不足和无法通风,隐藏在底部的树叶会变黄并下垂。

解决方案:及时修剪。家里的许多富裕的树木已经长成草帽,没有修剪。作为一种观叶植物,丰富的树木很重要。但是太多的叶子阻碍了植物的生长是你的错。

幸运树增长得更快。对于盆栽植物,你可以修剪一些树枝,你不必勉强,豆芽很快就会生长,植物会变得更加茂盛。

原因七:土壤碱度

土壤是丰富树木生长不可或缺的因素。北方大部分土壤含有较多的盐碱,但丰富的树木喜欢酸度。土壤不是什么大问题。土壤缺乏富树所需的铁。营养不良的结果是叶子是黄色的。

Solution: Acidify the soil. The rich tree is suitable for growing in acidic soil, and changing the acidity and alkalinity of the soil in time can remedy the yellowing of the rich tree. There is no need to remove the basin, no need to change the soil, only need to apply a certain amount of ferrous sulfate in the soil, directly sprinkle it in the flower pot, which can increase the soil fertility and acidify the soil, killing two birds with one stone.

Pay attention to the process of acidifying the soil, do not use vinegar. Vinegar can indeed make the soil sour, but because of the radical change, it will damage the organic matter in the soil and will lower the fertility of the soil.

How to prevent yellowing of leaves?

Control the amount of water

In order not to let you cry because the leaves of the rich tree are yellow, we must do everything when it is not yellowed, first grab the amount of watering. Watering the tree for wealth should follow the principle of “do not dry, water, and pour through”. Under normal maintenance, you can pour water once every 15 to 20 days.

Reasonable lighting

Keep your fortune tree and do your best every day. From the end of April, choose a sunny and warm noon, move it to the outdoor or balcony, receive the sun, start for 1-2 hours, then gradually extend the time. You will receive unexpected results. Of course, in summer, it is best to put time in the morning or evening. At this time, the sun is mild and will not cause damage to the tree.

Moderate fertilization

Fertilize the rich tree, follow the principle of “thin fertilizer and diligence”, fertilize according to the growth of the plant, apply liquid fertilizer or mixed flower fertilizer every 1 to 2 weeks in the growing season, and add it when the plant is changed. Decomposed base fertilizer.

Control soil pH

xx 事实上,家庭中的大部分土壤都是直接从市场上购买的,而土豆中的土壤是酸性的。但为什么会出现黄叶现象?这与我们的浇水和土壤变化有关。浇水时,尽量选择酸性水(雨水,河水,放置后的自来水);此外,我们可以给硫酸亚铁溶液浇水,以确保土壤的pH值在适当的范围内。

定期清理树枝和树叶

首先,应及时修剪,切断密集,长而且病变的枝条,以增强植物的半透明性。其次,必须清洁叶面上的灰尘。叶面上过多的灰尘不仅影响外观,还会降低光合作用,导致叶片变黄。

及时预防和控制病虫害

在富裕树木的室内养殖中,由于通风,光线和湿度,难以避免病虫害。关键是要采取预防措施。除了阴雨天和冬天,还必须确保环境中的空气顺畅流动;在额外的高温季节,应防止每次喷洒杀菌剂。

保持适宜的温度

幸运树对温度,热黄,冷和黄都很敏感,所以适当的温度非常重要。富树的适宜生长温度为22-35°C,高于35°C,生长速度减慢。冬季的最低温度为16-18°C(基本温度和室内温度相当)。低于此温度,叶子变黄并脱落,低于10°C的植物容易死亡。

富饶的树叶是否被黄色切断?

黄叶出现在茂密的树上后,必须切掉黄叶。因为泛黄的叶子不含叶绿素或只含有少量的叶绿素,不仅可以使植物合成营养,而且还会消耗植物本身的营养。所以你需要切断它。

1,需要切断

发财树出现黄叶之后,是需要将黄叶剪掉的。因为发黄的叶片之中已经不含叶绿素或是只含有少量的叶绿素,所以它不能够像正常叶片一样进行光合作用为植株提供营养。反而,它的存在会消耗掉植株本身的营养,所以需要将它剪掉。

2、修剪方法

将出现黄色的叶片从基部剪掉或者摘掉。

3、后期养护

剪掉黄叶之后,需要找到它出现黄叶的原因,然后据此来改变养殖它的条件。比如说,如果平时浇的水太多导致它产生了黄叶,那么以后就要少浇水;如果平时将它放到日光太强的位置导致它被晒伤,那么就需要将它移动到阴凉的地方养殖。

发财树叶子发黄脱落怎样挽救?

一、更换花土

原因:如果养发财树使用的土比较粘重,容易板结,内部透气能力不佳。就会导致它的根系在其中无法正常的呼吸,从而发生腐烂。一旦根烂掉,那么植株无法正常的汲取养分,养分就会不足。叶片缺少养分,就会出现变黄、脱落等不良现象。

处理方法:为它更换上透气性比较好的新土。具体来说,可以将六份园土、两份基肥、两份粗砂均匀混合,作为它的新土。

二、增加光照

原因:如果在平时一直将它养在缺少光照的环境中,它就会缺光,叶片也会因此无法正常的合成养分。因此,就会出现脱落、变黄等问题。

处理方法:改变养殖它的位置,把它放到光线更加明亮的地方养护。但要注意,不要让它被强光曝晒。

三、调节温度

xxxx Cause: If the ambient temperature of its growth is too low, or too high, to make it uncomfortable, it is also prone to this problem.

Treatment: Adjust the temperature around it and try to control it between 20 and 32 °C.
