Management measures of different seasons in the production of cut rose
(1) Winter: it is mainly sunny, the light is strong, and the temperature difference between day and night is large. There will be a short period of extremely low temperature at the end of December. There is a large temperature difference between day and night in southern Jiangxi, which is good for the dry matter accumulation of cut rose flowers, which have large heads, many petals and bright colors. However, the temperature difference between day and night in the greenhouse in winter is often more than 20 ℃, and the temperature difference between day and night is too large, which will lead to blackening of petal edges and flower deformities in many cut rose varieties. The lowest night temperature for the growth of cut rose is more than 8 ℃. Too low night temperature is not conducive to the growth of cut rose, which mainly affects germination and sprouting.

Prevention and treatment of element deficiency of cut rose in production
When there is a lack of nutrient elements, the main reasons for the lack of nutrient elements are as follows: the difference or error of effective components in fertilizer is not consistent with the actual amount of fertilizer; the improper operation of fertilizer and fertilization results in precipitation and loss, which makes the proportion of nutrient elements out of balance; soil pH value, soil temperature and poor permeability affect the effectiveness of nutrient elements, so that rose can not effectively absorb nutrients. Therefore, in soil cultivation, as long as we adhere to normal fertilization, it is generally not easy to lack large and medium elements, sometimes due to the rapid growth and high consumption of rose.

How to make roses bloom early
Rose is a kind of sensitive flower sequence, which often hibernates due to low temperature in northern China. However, due to its special physiological function of accumulating temperature and promoting growth, it can accumulate high and low temperatures under certain temperature and light conditions for its growth and development. Therefore, appropriate measures can be taken to make it bloom earlier at the beginning of the year. First, the selection of cold-resistant ink red, pink rose varieties This rose has thick branches, luxuriant branches do not have the characteristics of fast growth of new shoots, the first leaves purple-red, compound leaves are mostly composed of 3~5 leaflets, leaves are smaller and thicker. small

How to cultivate natural tree rose
Natural tree rose is very different from ordinary tree rose. Because of the use of special cultivation measures, it has effectively solved the problems such as the thickening of the trunk of ordinary tree rose, the difficulty of long-term coexistence of multiple varieties in one tree, and a new breakthrough in tree life. This method is unique from the cultivation of rootstocks to grafting and then to the later stage of management. it is a set of mature methods for cultivating high-quality tree roses. Industry experts generally believe that this technology is currently in the leading level at home and abroad. Cultivation of Natural Tree Rose

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

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. To avoid rose cuttings

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

Cutting technique of Autumn Rose
Rose can be cut all the year round, but the autumn cutting method is simple, easy to manage after winter, and can blossom in the same year after planting in the pot the next year. From September to October and the temperature from 20 ℃ to 25 ℃ is the best time to cut rose, and its survival rate is more than 95%. The neutral sandy loam with better water and fertilizer conditions (pH value 6.5 to 7) should be selected for cutting seedling raising in seedling bed preparation. If the soil is clayey and heavy, it can be mixed with appropriate amount of fine sand during soil preparation. If the soil has high sand content and low fertility, an appropriate amount of organic fertilizer can be applied during soil preparation.

Cultivation and Management of cut Rose
Rose, colorful, elegant aroma, has always been loved by people. The cultivation of fresh cut rose in solar greenhouse can supply the market all the year round, which can be regarded as another new way for farmers to get rich. First, grafting and propagation. Wild rose or special rootstock varieties were used as rootstocks and grafted by grafting or bud grafting. The rootstocks were sown in early April and transplanted in April of the following year. The nursery bed should choose fertile and loose sandy soil with a row spacing of 20 cm × 80 cm, budding in June and planting in the third spring.
