Planting method of Chinese rose

Pot planting method: the suitable temperature for rose growth is about 15-25 ℃, like light but not strong light, generally put on the pot during the dormant period, change the pot every year or every other year, culture in a place with ventilation and plenty of sunshine in spring, summer and autumn, timely watering and fertilization, and pruning branches. Open field planting: you can choose to plant in high terrain, sufficient light, good ventilation and slightly acidic soil, pay attention to reasonable close planting, and do a good job in fertilization management.

1. Potted planting method of Chinese rose

1. Lighting

Rose is a kind of light-loving plant, if the light is not enough, the branches will be relatively slender, but it can not be directed directly, which is not conducive to the development of flower buds.

2. Temperature

It takes about 45 days for rose flowers to sprout to blossom, and the suitable growth temperature is about 15-25 ℃. The flowers blooming at this temperature are larger and more beautiful. When the temperature rises to 30 ℃, the flowers grow slowly, more than 30 ℃, the flower color becomes lighter and the flowers are smaller.

3. Potted soil

For 2-3-year-old seedlings, it is better to trim the roots and put them on the pot first, properly cutting off the old roots is beneficial to promoting the development of new roots, and the plants should be correct when planting, so that the roots should be fully stretched and the basin soil should not be filled too full.

4. Change the basin

Generally, rose flowers go to the pot during the dormant period, the growth rate of rose is faster, and the demand for fertilizer is large. The basin should be changed once a year or every other year, and the basin needs to be changed during the dormant period. After changing the basin, it needs to be watered twice, except in winter. The other three seasons should be placed in a place with good ventilation, sufficient sunshine and no stagnant water.

5. Pruning

The rose can be pruned properly after the Qingming Festival, cutting off its weak branches, cross branches, transverse branches and over-dense branches, leaving only strong branches. In order not to let nutrient loss, the selected branches can be selected from the base with 3-5 bud holes, and all the above branches can be cut off, which is more conducive to leaving branches to absorb enough nutrients and promote their growth.

(1) pruning must be carried out after bud germination. Too late pruning will affect the first flowering. In order to grow evenly, each plant can leave 3-5 main branches, no more than 7 branches.

(2) the rose still needs to be pruned in the middle stage of growth, mainly cutting off the sprouting branches of the grafted rootstocks and removing the residual flowers and excess buds with leaves after anthesis.

(3) the rose needs to be pruned once before the beginning of winter, which must be evenly pruned. The big flower variety can leave 4-6 strong branches, each branch has a lateral strong bud at 30-40cm, the rest is cut off, the vine and vine varieties are cultivated, and the old branches, weak branches and disease and insect branches can be cut off.

6. Watering

Potted rose flowers need to be watered thoroughly, do not need to be watered, the summer temperature is higher, water evaporation is faster, need to appropriately increase the amount of water, especially in the evening.

7. Fertilization

Generally, there is no need to apply fertilizer in summer, and healthy plants can use the method of applying thin fertilizer frequently, about 1-2 times a week, shading properly before 11:00 in the morning, and lighting after 4 o'clock in the afternoon to avoid strong direct light as far as possible. it is beneficial to photosynthesis and accumulate nutrients for the next stubble flowers.

Rose flowers need to be fertilized after pruning. 50% of human feces and urine can be mixed with 2% superphosphate, and 3% of human feces and urine or 1% urea can be applied in the middle of February. Note that it must not be fertilized when it is slightly red, which will lead to young root injury, thus affecting plant growth and even death.

Second, the open field planting method of rose

The main results are as follows: 1. the root system of Chinese rose is relatively developed, the plant is strong, the growth rate is relatively fast, the flower is relatively large, and the ornamental value is relatively high, so it can be planted reasonably according to the habits of different varieties. When planting Chinese rose in the open field, it should be planted in relatively high topography, good ventilation, sufficient sunshine and slightly acidic soil.

2. After selecting the planting site, the soil preparation is fertilized, and the basic fertilizer is mainly organic fertilizer. The erect varieties can be planted according to the row spacing of about 75cm, the vertical varieties can be planted according to the row spacing of all 40cm, the expansive varieties can be planted according to the row spacing of about 100cm, and the rattan varieties can be planted according to the row spacing of 200cm.
