Comprehensive explanation of rose cultivation generally has three forms of flowers and plants knowledge, let's take a look together.
Rose cultivation generally has three forms, potting, ground planting, and cut flower cultivation
Roses are known as the queen of flowers and monthly red. Nanyang roses bloom all year round, with strong fragrance, unique shapes, and are loved by many. Nanyang roses are widely used in parks and green belts, not only having high ornamental value but also special medicinal value. Many cities have rated roses as the city flower, which shows people's love for roses.
Tree roses do not have strict soil requirements, but loose, fertile, organic-rich, slightly acidic loam soil is more suitable. They prefer a warm, sunny, well-ventilated, and well-drained environment. Most Nanyang rose varieties are suitable for daytime temperatures of 15°C to 26°C and nighttime temperatures of 10°C to 15°C. In winter, when the temperature is lower than 0°C, they enter dormancy. Some varieties can withstand low temperatures of -15°C and high temperatures of 35°C, but when the summer temperature continuously exceeds 30°C, they enter semi-dormancy, the plant grows poorly, although they can form buds, the flowers are small with few petals, dull in color, and lack luster, losing ornamental value.
Rose cultivation generally has three forms, potting, ground planting, and cut flower cultivation. For cut flower rose cultivation, it is first necessary to select varieties according to market demand, usually focusing on HT series varieties, and the main technical points are as follows, please refer to the introduction by the editor of the tree rose planting base:
(1) Environment selection and seedling planting: The planting site should have a high and sunny terrain, good ventilation, deep turning before planting, and sufficient base fertilizer. The timing of seedling planting depends on the age of the seedlings, and can be done in spring or at the beginning of the plum rain season. The spacing of the planting rows, taking a 6-meter-wide flower greenhouse as an example, make four 2-meter-wide beds, plant 2 rows per bed, with a row spacing of 50 centimeters and a plant spacing of 20 centimeters. Different varieties may have some differences.
(2) Pruning: Pruning can determine the flowering date, the number of flowers per plant, and the grade of the flowers. Generally, HT series varieties are controlled to produce 18-25 branches per plant throughout the year. After flowering, it is necessary to remove diseased branches, weak branches, and degenerative branches in time, and properly adjust the height of the plant. When cutting flowers, the lower two sets of leaves should be retained. In the early stage of germination, it is necessary to thin the buds, promptly remove the lateral buds and secondary buds on the flowering branches to prevent the diffusion of nutrients.
(3) Fertilization and water management: Cut flower roses like fertilizer and water. In spring, summer, and autumn, they should be watered every other day. In summer, high temperature, combined with ditch irrigation, works better. In winter, water is applied every 5 days. Since frequent watering can cause soil compaction, it is necessary to loosen the soil in time. The amount of fertilizer, generally for a greenhouse of 180 square meters, the application of 40 kilograms of ripe dry cake fertilizer is sufficient. During the vegetative growth period, 5 kilograms of urea is applied monthly, and during the flowering period, phosphorus and potassium fertilizers should be increased, and nitrogen fertilizers reduced. For soil that has been continuously planted for three years, trace elements should be added.
(4) Winter insulation: The temperature for cultivating cut flower roses is 25°C during the day and 15°C at night, but it is difficult for general greenhouses or greenhouses to achieve this. If the temperature can be maintained at about 10°C at night, it can also grow normally. For a production greenhouse of 180 square meters, if it can be equipped with 3 overhead 1000-watt ground heating lines, it can withstand an outdoor temperature of -5°C. When the indoor temperature is lower than 0°C, small flower buds are easily frozen.
