Can the climate in Yichun, Jiangxi grow roses?

The climate in Yichun, Jiangxi Province can grow roses, and this area is suitable for the growth of roses.

Description:

Yichun city is located in low latitude and has the characteristics of subtropical humid climate.

Although the weather is changeable in spring, it warms earlier. It is wet and rainy at the turn of spring and summer, sunny and hot in summer, dry in autumn and cold in winter, but the frost period is short.

Four distinct seasons, short spring and autumn, long summer and winter.

Generally speaking, the city has a warm climate, abundant sunshine, abundant rainfall and a long frost-free period.

The annual average temperature of the whole city 17.2℃.

The average temperature in the hottest month is 28.8℃ in July, 5.3℃ in Leng Yue 1 month and 267.9 days in frost-free period.

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.

China is 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.

So this area is suitable for the growth of roses.

Growing habits:

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.

Roses are masculine plants, which are rich in color and fragrance in sunny conditions.

If the sunshine is less than 8 hours in the growing season, it will grow white without flowering. The requirement for air humidity is not strict, and rust and powdery mildew will occur at low temperature and high humidity; The flowering period requires the air to have a certain humidity; When drying at high temperature, the oil yield will decrease. Roses do not require high pH value of soil, and can grow normally from slightly acidic soil to slightly alkaline soil.

In winter, snow-covered areas can tolerate the low temperature of -38℃ to -40℃, and areas without snow can tolerate the low temperature of -25℃ to -30℃, but they can't tolerate the dry wind in early spring.

In areas with unfrozen soil and windy ground, branches are often blown dry by the wind; If the soil has been thawed and the roots continuously transport water and nutrients to the stems, the wind will not cause serious damage.

Areas with dryness greater than 4 need irrigation conditions to develop normally.

Culture type:

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.

Training points:

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.
