The latest breeding method of Rose

Rose is one of the world-famous ornamental plants, happy to grow in the bushes by the roadside, by the field or in the hills. Wild roses are naturally distributed by streams, roadsides and garden sides, corners and other places, often dense and clustered, full of brilliant branches, light rain or morning dew, the petals are red and wet, the scenery is quite good, and it has high planting value. Let's take a look at the breeding methods of roses.

The planting time of the rose

The rose can be planted all the year round, keeping the root system moist in the growing season and preventing cold in winter, but it is suitable from autumn defoliation to spring sprouting, and the best planting period is from autumn defoliation to freezing. In order to make the plant grow and enlarge the flower cluster as soon as possible, large holes must be planted with 1 meter long and 1 meter wide, 0.6-0.8 meters deep, or digging planting ditches with 0.6-0.8 meters deep and 0.8 meters wide. Plant application of organic fertilizer, calcium superphosphate, mixed with the soil and concentrated application in the soil depth of 0.2 to 0.5 meters, after planting, timely irrigation.

Propagation methods of Rose

Rose seed can be used for raising seedlings, but it is easy to survive by using tender wood cuttings in the same year in production. Valuable varieties are difficult to cut and can be propagated by pressing or grafting. Seedlings of asexual reproduction can blossom in the same year. For the seedlings used as potted flowers, the older branches of fine varieties should be selected, the seedlings should be raised by striping method, and attention should be paid to pruning the main buds and artificial dwarfing. For seedlings used as cut flowers, varieties that can form mother branches and colorful flowers should be selected to raise seedlings. Roses can also be propagated by tissue culture, water culture, grafting, plantlet and so on.

Cultivation and Management of Rose

The main results are as follows: 1. Fertilization management: Rose likes fertilizer and tolerates barren. Liquid fertilizer dominated by nitrogen can be applied once or twice in March to promote the growth of branches and leaves. From April to May, fertilizers dominated by phosphorus and potassium are applied three times to promote more flowering of its poly-pregnant buds. After anthesis, there can be no more fertilization. Rose positive flowers, like warmth, but also hardy, North China and its south, can survive the winter outdoors safely.

2. Watering management: the rose is happy and moist and afraid of waterlogging. From budding to blooming, the water can be watered more appropriately, with the soil moist but not waterlogged as the degree, not too much watering after flowering, the soil should be dry and wet, and attention should be paid to drainage and waterlogging in the rainy season.

3, pruning: the rose has strong sprouting power and luxuriant growth. if it is not pruned in time, under the conditions of muggy, humid, lack of light and poor ventilation, diseases and insect pests are easy to occur, so a pruning should be carried out after flowering. When pruning, you can choose the sturdy branches that are semi-lignified in the same year, place them in the semi-shade, transplant them in the following spring after survival, or cut off the roots of the sprouting daughter plants before sprouting in early spring.
