The month is limited to injecting branches and stems, and there are more pruning strips and grafted stems. The disease occurred on the branches, which was originally reddish-purple spots, and then gradually spread to the large prototype. Nectar is dark brown, with reddish-brown or purple-brown edges, slightly upward. The contrast between the surrounding brown and purple edges and the green of the stem is obvious. Bachelor's spots are dark brown, with longitudinal cracks, dark brown granules, and ready-to-eat robes. This kind of crack is an important feature of mineral diseases. When the disease is serious, it expands and surrounds the branches, leading to some diseases and deaths. The dead zone spreads downward, the disease is slightly trapped in the boundary of excitation, and finally the dead branches turn yellow. This is spore, and this is spore. Petals are brown and will not bloom normally.
First, prevent the moon,
1. Find the branch and trim it.
2. After cutting off the broken branches, cut them near the axillary buds. Pruning should be carried out in sunny days, and cutting should use 1: 1: 15 copper sulfate, lime and water.
3. Spray after pruning, and the reagent can be a mixture of 50% hermaphrodite 800- 1000 times solution, 0.2% octyl zinc and 0. 1% benzoic acid.
Second, the top of this line is black:
The black pole on the moon is not necessarily sick, but it is probably a problem, especially the newly transplanted rose, which is easy to lead to the black pole on the moon without a new source.
But if it is a new root, it must be treated, which may be caused by pathogenic infection.
Processing method from the top of the moon:
1. For black branches, you must cut them thoroughly, don't disappear, just cut a little black branches, and you must cut them together with the healthy branches under the black branches, and you don't want to leave.
2. After the black branch is repaired, it is best to seal the wound with wax, and the wound is completely closed to avoid reinfection of the wound after the rain, and the black branch will continue.
Third, the lines turn black from bottom to top:
It is often difficult to get up from the black pole at the bottom of the moon, but it can be saved if it is not very serious. Of course it's all black, so it's really nothing.
Here, you will focus on the first aid methods in Hei Bang:
1. After discovering Hei Bang, we should devote ourselves to seeing the roots of the roots. The floor with lumps should be washed into rotating roots. The roots should be cleaned and inspected. If all the roots are black, it is really hopeless, but if there are good roots, it may be an attempt.
2. For roots that are not completely blackened, remove necrotic and dead roots and apply tissues to skin tissues. 3. Remove some dead branches and black spots, leaving only some slightly better leaves for photosynthesis.
4. After cleaning, spray the whole plant, especially the whole plant. You can use the soaking method.
After treatment, it is necessary to reconfigure the sterile and pollution-free new soil for plants. If this species is kept in a cool and ventilated place, it can gradually glow.
It should be pointed out that we should use other healthy plants to avoid infection during the whole rescue process.
6. When you find signs of success this month, don't rush to fertilize and continue to take root. Turn around and there is no light, so you must not violate the light and give it to the light. The full set should be given after the delay.
In order to improve the resistance to the moon, organic fertilizers fermented by pure plants can be used to enrich the phosphorus content, promote strong life and improve the resistance of plants.
