Is Gulang County in Gansu Province Suitable for Growing Roses?

Gulang County, Gansu Province is suitable for rose cultivation, which belongs to the range of species distribution, so it is enough to pay attention to suitable soil cultivation.

Analysis and explanation:

Gulang County belongs to Wuwei City, Gansu Province, located in the middle of Gansu Province, and has a temperate continental arid climate.

The terrain is high in the south and low in the north, with an altitude of1550m to 3469m. The landform types are complex and diverse, and the landform zoning phenomenon is obvious.

The southern part of the county is middle and high mountains, the middle part is low hills and gullies, the middle part is inclined plain oasis agricultural area, and the north part is desert area.

Roses are distributed in Beijing, Jiangxi, Sichuan, Yunnan, Qinghai, Shaanxi, Hubei, Xinjiang Uygur Autonomous Region, Hunan, Hebei, Shandong, Guangdong, Liaoning, Jiangsu, Gansu, Inner Mongolia Autonomous Region, Henan, Shanxi, Anhui and Ningxia Hui Autonomous Region.

Roses like sunny, cold-resistant and drought-tolerant, and loose and fertile loam or light loam with good drainage. They don't grow well in clay loam, and they don't bloom well.

It should be planted in a well-ventilated place away from the wall to prevent sunlight from reflecting, burning the bud and affecting flowering.

So this area can be cultivated.

Training points:

There are two main ways to cultivate roses: one is pruning. This method requires high pruning technology, slow flowering, high yield and low proportion of commercial flowers.

The second is the branch pressing method. The requirements for pruning techniques are not high, the flowers bloom quickly, the yield is low and the quality of flowers is good.

Before planting, dig deep into the soil and disinfect the soil with debittering agent to make the soil and fertilizer completely mixed. Frame width 12 cm, groove width 40 cm, and frame length 5.5~6.0m.

Don't beat the soil too fine, which will lead to slow growth of seedlings and slow growth in the later stage. Leave about 50 cm in the south of the greenhouse.

There is no strict restriction on planting time, and it can be planted all year round, with the best in spring and autumn.

When planting, two rows are planted in each border, the row spacing is 40 cm, the plant spacing is 10~ 12 cm, and the spacing between the two sides of the cultivation bed is 40 cm, with an average of 7~8 plants /m2, and the seedling protection is about 63,000 plants /hm2. Different varieties have different planting densities.

After slowly planting seedlings, timely intertillage and loosen the soil to prevent and control red spiders, aphids and powdery mildew. When the plant grows to about 25 cm, the branches will be pressed at noon on sunny days, otherwise it will break easily.

Roses are usually planted for five years, so fertilization should be more and heavier. Generally, about 60t/hm2 of organic fertilizer, 750kg/hm2 of diammonium phosphate and 2250kg/hm2 of calcium superphosphate should be applied, and the organic fertilizer should be fully decomposed.

Water the seedlings about 7 days before planting to protect the seedbed soil from moisture. Water in time after planting, and the planting water must be thoroughly watered. 12 ~ 16 In sunny days, water 1~2 times a day to keep the bed surface moist.

Water topdressing should be carried out according to soil conditions, climate conditions and the growth of branches and leaves.

In the process of rose cultivation, if the soil moisture is insufficient, the positive leaves of the plant will fall off.

When the surface is dry, water it in time to keep the surface moist.
