What should I do if the cherry blossom sapling is fake? 20

The phenomenon of fake life.

At this time, the planting of cherry trees is an anti-seasonal attack.

Although the leaves grow after transplanting, the root system is seriously injured and loses its function, and the shoots grow by the water in the tree, without the support of water, once the water in the body is exhausted, the shoots will wither and appear"Fake live"Phenomenon.

It should be transplanted during the dormant period.

There are many causes, usually diseases or drug damage.

1.In the growing season, herbicides have been applied to the ground, and the roots die after low temperature in winter, and the trees begin to sprout and develop leaves in the spring germination season, but the root system dies and cannot provide nutrients, and the leaves begin to wilt and die after the nutrients of the trunk are consumed.

2.The soil is heavy and clay, causing the roots to be unable to breathe and slowly die. The soil is clayey and not suitable for growing cherry blossoms. The root system of cherry blossoms is very shallow, and if the water is waterlogged for more than 24 hours, the root system will not be able to breathe and suffocate and die.

3.Rhizobia. You can peel off the soil to see if there is a round black or brown ball on the root, that is the root nodules, if the leaves have wilted, then it is basically hopeless, if the dead horse is regarded as a live horse doctor, you can pick up the soil to remove the root nodules and then use rooting agent and fungicide with water to irrigate the roots.

4.In the case of insect infestation, it can usually be seen from the outside, but if the trunk is not drilled, it is generally not an insect infestation.

Transplanting this kind of sapling, there will be this phenomenon of dead seedlings, 100 1-5 trees are within the normal range, this is the process of transplanting itself, the root system is injured and infected, or there are bacteria in the soil that cause damage to the root system, the root system is not developing and rooting, or the rooting is slow, and the inhibition is more serious, which will cause an illusion.

The half-moon growth after transplanting is still relatively good, germination when it is time to germinate, and leaves are grown when it is time to grow leaves, but the root system does not transport nutrients at all, or only transports a very small part of nutrients, and in the process of growth, it is only consuming the plant's own nutrients, when it is consumed, when it is dead! This is a common occurrence of such dead seedlings.

There is also the process of maintenance, especially the potted cherry blossoms, the choice of soil is very important, the root system of the cherry blossoms is relatively shallow, the selection of soil must be loose and breathable, slightly sandy soil is the best, loose soil can also be with the help of the fertilizer of the fungus.

The cherry blossoms are most afraid of long-term water accumulation, the root system of cherry blossoms encounters poor breathing, and the waterlogged soil will have local root rot symptoms, although the root system also has a certain self-healing ability, the fear is that the soil is silted up for a long time, and soon a large area of rotten roots will appear, and the natural plant will slowly die.

Pay attention to the selection of soil when transplanting and potting, remember to kill and sterilize when potting bare roots, and the soil can only be used after being exposed to the sun! Only in this way can the phenomenon of fake life be reduced.

This is the 'fake life' of the cherry blossom seedling after planting, that is, it does not really survive, but only relies on the original nutrients in its own body to sprout and grow leaves. Once the nutrients in the body are depleted, the leaves that grow are unable to survive due to food and water depletion.

After the seedlings are planted in spring every year, some seedlings often have the following phenomena: 1Seedlings germinate and develop leaves quickly, but when they grow for a period of time, they will suddenly die of branches and leaves, which is called "fake life"; 2.

Seedlings do not germinate for a long time, and only germinate and grow after a period of time or even the next year, this phenomenon is called "suspended animation".

The phenomenon of "fake life" of seedlings is because some seedlings extract branches by virtue of their own stored nutrients, but because the root system is too weak or the damage is too heavy when transplanting, or the planting is too deep, the conditions are unsuitable and die, when the seedlings that germinate and shoot do not get the best water and nutrients for a long time, and the nutrients stored in the seedling body are exhausted, so they dry up and die. The phenomenon of "suspended animation" of seedlings is mainly caused by poor seedling quality, poor root growth and development or excessive injury to seedlings, and failure to create a suitable environmental conditions for seedling growth and development after planting.

Control measures: 1) Planted seedlings should be strong, fresh and with developed roots. At the same time, when moving seedlings, pay attention not to hurt the roots too much, and try to maintain more roots.

2) When planting seedlings, the pit should be larger, and the gravel, bricks and tiles should be cleaned up, loam should be placed, and an appropriate amount of fertilizer should be applied.

3) When planting, it should not be too deep, and it is generally appropriate to have the root neck or grafting interface level with the surface.

4) When planting seedlings, the root system should not be in direct contact with the chemical fertilizer, but the chemical fertilizer should be mixed with the soil, and covered with some loam on it, and then planted.

5) Watering thoroughly is also very important to avoid hanging roots.

6) The stem of the seedling should be determined by the tree and the bud, and the full bud must be selected when shaping, so as to avoid leaving weak buds and blind buds.

7) When watering, water the roots of the happy forest rooting liquid and resurrection spirits in time to promote the growth of new roots and prevent root rot.

8) Timely replenish the hanging needle solution or activation solution of the happy forest to the trunk to regulate the growth and supplement the nutrients and water required after tree transplantation.

Generally speaking, any tree will survive for a while after transplanting, and this is because the tree itself has a certain amount of nutrient water in it. The longest can survive for 5 months. Therefore, to observe whether the trees are alive or not, we have to wait for half a year to know.

Good lychee net planting lychee is based on the second germination after half a year.
