What happens when the leaves of Schizandra turn yellow in summer?

The leaves of Schisandra chinensis are water-soaked, or the leaf margins turn yellow and black, and some even die of the whole leaf. The main reasons for this phenomenon are: low temperature and high humidity in spring, so that the new roots of the plants do not take root; At the same time, due to the low temperature of frost, the leaves are dehydrated and appear water-immersed; After low temperature, the temperature increases slightly, and a large amount of water vapor transpiration causes the herbicide to drift, which aggravates this damage. In addition, for some whole leaves to die, it is mostly caused by stem rot on the stem close to the ground.

It can be seen that there are multiple reasons for the yellowing and wilting of Schisandra chinensis leaves, and the degree of damage caused by different factors is also different. Farmers should analyze as appropriate. It's hard to defend against, and it's hard to ** when it happens.

For the leaves of the tall plants, the leaves are only partially yellow, and there is still a certain function, there is no human interference, and there is no leaf loss, which can be maintained until the old autumn, so do not rush to remove the leaves. For small seedlings, after the temperature rises and stabilizes, the yellow part of the top can be appropriately cut off to promote the production of new leaves or vines.

There are two causes: one is caused by drought and the other is caused by water damage. We don't ignore drought, but water stains are rarely found, and poor soil aeration causes water to be very watery.

Both of these conditions will cause the leaves to wither and yellow, and the natural growth environment of Schisandra chinensis is mostly loose and aerated humus. You look at the likelihood that that situation is caused.

The leaves of Schisandra chinensis are water-immersed, and some even die entirely.

This is too simple, there are several schisandra bases in the Northeast that spray like this in this situation. Look at the picture below whether it is yellow or white, and use the medicine three times.

Schisandra leaf blight and its control.

It mostly occurs from late May to mid-July, and the lesions are yellow. In the early stage, it starts from the tip of the leaf, gradually expands and spreads, and in severe cases, the whole leaf withers and dies. The disease is severe when there is high temperature, humidity and poor ventilation.

Prevention and control methods: "Liangguoan" 100-150 times + "garlic oil" 1000 times + "Wofengsu" 600 times + silicone spray, more than 3 times, each time with an interval of 5-7 days, ** in late April before the onset of the disease, spray once a week, even spray 2-3 times can also be sprayed with Bordeaux liquid once a day.

Let's see what others have to say.

You look at whether this ** is the above situation or the following situation, and you can quickly cure it with a method.
