Culture methods and matters needing attention of small roses in the four seasons

Soil: it is suitable to choose slightly acidic or slightly alkaline soil mixed with sandy soil, vermiculite and coarse sand. Watering: water 1-2 times a week to avoid stagnant water. Fertilization: during the growing period, diammonium phosphate solution was sprayed on the leaf surface, once a week, farm manure was applied in spring, human and animal manure or flower fertilizer was applied after budding, calcium superphosphate or dihydrogen phosphate solution was applied in bud, nitrogen fertilizer was avoided in flowering stage. Lighting: need to ensure 6 hours of light every day. Temperature: 15-25 ℃ is the best, not higher than 30 ℃.

First, the culture method of small roses of the four seasons

1. Soil selection

The four seasons small rose has strong adaptability, and the slightly acidic or slightly alkaline soil mixed with sandy soil, vermiculite and coarse sand can be planted, but try to choose the area with sunny leeward, good drainage, fertile and loose, which is beneficial to crop growth.

If it is planted in a large area, you need to build a nursery ground, first make a nursery bed with wide 100cm and high 25cm, and a wide 50cm trail, build a high 50cm arch shed at the top, cover it with film, build a shade shed at the left and right distance of 80cm above the arch shed, cover the bottom with a layer of 10cm gravel or coarse sand, and cover with a layer of fine sand soil that has been screened, and try to make the soil slightly flat after crushing to keep the channel unobstructed.

2. Watering method

Small roses in the four seasons do not need too much watering in the growth process, more resistant to drought, so usually watering can be kept dry watering, usually watering 1-2 times a week, the summer temperature is high, water evaporation fast should increase the watering times, usually the amount of water should be moderate to avoid causing stagnant water.

3. Fertilization management

During the growing period of small roses of the four seasons, diammonium phosphate solution should be sprayed on the leaves, once a week, rotten farm manure should be applied before spring germination, human and animal manure or flower fertilizer should be applied after germination, calcium superphosphate or dihydrogen phosphate should be applied according to aqueous solution during budding, nitrogen fertilizer should be avoided during flowering to prevent falling flowers, and if the winter temperature is low, the fertilizer can be buried in the pit around the root of the crop and then watered.

4. Sufficient light

Siji small rose is a kind of sun-loving crop, sufficient light can promote its growth, lack of light will lead to crop malnutrition and plant dwarfism. Light time should be guaranteed at least 6 hours a day, so that the flowers will be colorful.

5. The best temperature

Temperature is very important and strict for the growth of small roses of the four seasons. When the temperature is higher than 30 ℃, it will lead to plant withering, and if the temperature is lower than 8 ℃, it will cause freezing injury. The most suitable temperature for the four seasons roses is 15-25 ℃. If the temperature is well controlled, the quality of the crops will be high.

Matters needing attention of the four Seasons Little Rose

1. Ramet

The rhizome of Siji rose is tenacious, with many and luxuriant ramets, which can concentrate nutrients and promote growth and development. Ramets usually occur before spring germination or after defoliation in autumn, which is also one of the methods of crop reproduction.

2. Pruning

The timing of pruning should be carried out during the dormant period of deciduous leaves in winter, cutting off 2/3 of the old, weak and withered branches, and the rest to promote the re-growth of new branches at the bottom. Because the flower buds grow at the top, they should be pruned rather than cut short.

3. Watering

The small rose of the four seasons is a shallow-rooted tree species, which can be watered for 5 days in summer. It is usually properly watered, watered before and after flowering, and watered in rainy season.

4. Removal

After flowering, the four Seasons Rose should remove and clean up the residual flowers and fruits, so as to ensure that the nutrition of the plant will not be superfluously absorbed, can effectively promote branch growth and prolong the flowering period, and the flowering effect is much higher than that of the crop plants without removal management.
