How to prevent the phenomenon of "fake living" of rose cuttings
Autumn is a good time for softwood cuttings of rose. At present, cutting is still the main method of breeding rose, it can not only maintain the characteristics of excellent rose varieties, but also has high propagation coefficient, short production cycle, low investment and quick effect, so it is still used by the majority of flower farmers. However, in the process of rose cutting, the phenomenon of "fake living" often occurs because of lack of experience or improper methods. In other words, when the cuttings were cut for 10 days, the axillary buds on the cuttings sprouted or sprouted leaves, and they looked alive, but soon wilted and died.
If you want to avoid the phenomenon of "fake living" of rose cuttings, first of all, when selecting cuttings, you can not choose the branches that have sprouted shoots to do cuttings. Especially when using tender wood cuttings in the growing season, we should also pay attention to selecting branches with high maturity, full axillary buds and ungerminated branches as cuttings. If there is an urgent need to use the germinated branches of axillary buds as cuttings, and when the length is more than long, the germinated section can be cut off and reused. If it is a short branch, the germinated axillary buds can be removed with a sharp knife or completely removed to inhibit their development and let the lower axillary buds sprout. In this way, it can be promoted to take root first, and then sprout leaves.
Secondly, if you want the rose cuttings to root and then send leaves, you should not only master the appropriate temperature and humidity, but also pay special attention to making the temperature of the cutting seedbed medium higher than the air temperature 1 ℃, which can adjust the internal nutrition of the cuttings to transfer to the lower end, first for the rooting needs of the lower part, and can promote the husband to root and then send leaves.
Third, especially in autumn, it is a good time for rose softwood cutting, when rose is in the growing season, it is very important to protect mother leaves and prevent shedding when cutting with tender wood. Because the mother leaf now undertakes the task of forming callus, producing adventitious roots and axillary bud sprouting leaves in the process of cuttings survival. Therefore, it is more important to ensure that the mother leaves do not fall off, especially for softwood cuttings in autumn. It must be noted that cuttings must not be cut from the diseased mother plant, and the seedbed and media should be strictly disinfected and sterilized, and can see the light as soon as possible, do a good job of seedbed ventilation, and ensure to improve the survival rate of rose cutting.

How to control downy mildew of rose
Downy mildew is a fungal infectious disease. Downy mildew of rose is a destructive disease with rapid onset and serious harm. It mainly damages the new branches and leaves in the middle and lower parts of plants. At the early stage, chlorosis spots appeared on the back of lower leaves, and the spots were irregular and covered with frost mold layer. At the late stage, they were dark purple, like water immersion, until they became brown. The disease spots were polygonal and gradually became burning. When the damage was serious, all the leaves fell off and the plants died. Control measures 1. Reasonable close planting, each square meter area should not exceed 12 plants, at the same time

Autumn rose should prevent diseases and promote growth.
The post-autumn rose has once again entered a period of peak growth. However, some roses begin to yellowing, with black spots in the middle, a few fallen leaves at the base and all the leaves at the base, and the bud falls before it opens. This is mainly due to mismanagement. In autumn, due to too much water, it is easy to cause rose diseases, mainly black spot. In addition, the basin soil is often too wet and it is difficult to breathe at the root, which leads to the complication of ldquo; & rdquo;, makes the bud wither and fall. The rescue method is to remove the diseased leaves and diseased branches in time and destroy them to prevent
