How to raise carnations to be healthy?
Cultivation method of carnation:
1, soil selection: carnation is a fibrous root herb flower, and its root system likes to grow in loose and fertile soil or well-ventilated medium. The best soil for planting carnations is sandy loam. The ventilation gap of soil accounts for about 30% of the ideal. The sticky and silted soil is not conducive to the growth of carnation and needs to be improved. Its core is to coordinate the relationship among solid, liquid and gas in the soil.
2. Temperature requirement: Temperature plays a qualitative and quantitative role in the growth and development of carnation, which is manifested by its influence on its growth speed, the shape and size of flowers, leaves and stems, the output of cut flowers and the life span of cut flowers. Carnation is a cool plant. The optimum temperature for its growth and development is 65438 09 ~ 2L℃, and the temperature difference between day and night should be kept within 65438 00℃. When the temperature is too high during the day, carnations have narrow leaves, small flowers and poor branches. When the temperature is too high at night, there will be abnormal reactions such as weak stems, small flowers and good color. The temperature is higher than 350℃ in summer and lower than 9℃ in winter, and the growth is slow or abnormal or even stopped.
3. Requirements for light: Carnations have the highest requirements for light among known plants, so there is no need to worry about the adverse effects of strong light on carnations except for seedling raising or full flowering. Carnation is an accumulated long-day plant. The longer sunshine accumulation time, the more it can promote flower bud differentiation, and then bloom early, improve flowering uniformity and cut flower yield. Auxiliary lighting can not only promote the elongation of plant internodes and inhibit the growth of lateral branches, but also increase the diameter of corolla and increase the brightness and color of flowers.
4. Watering method: Carnations are shallow-rooted flowers, and the planting depth should not exceed 2 cm. After planting, water it 1 time, and then water it when the soil is dry. Carnations are not resistant to moisture. In addition to increasing the amount of water in the vigorous growth period, flowering period and midsummer, it is generally not advisable to water too much to maintain a certain amount of water in the soil. Avoid excessive soil moisture during flowering.
5. Fertilization method: Carnation is a shallow-rooted plant, and its root system is mainly distributed in 20 cm soil layer. Sufficient base fertilizer should be applied during cultivation. Organic fertilizers, such as manure, compost and bone meal, are used as base fertilizers to improve the physical properties of cultivated soil and enhance its fertility, making it a light and fertile loam rich in humus, and the base fertilizer can only be applied after composting. Carnation has a long growth period and needs to be supplemented with soil fertilizer. Topdressing is based on the principle of thin fertilizer and diligent application. Topdressing 1 time every 25 ~ 30 days for open field planting. If the original fertility of soil is not high, the interval of topdressing should be shortened. Potted plants can be topdressing 1 time every 7 ~ 10 days. In the two growth peaks, the number of topdressing can be increased. The fertilizer can be cake fertilizer water, chicken manure water, or compound fertilizer applied alternately.
Matters needing attention in carnation cultivation:
1. It is advisable to keep the soil moist during the vigorous growth period in spring and autumn to meet the needs of growth and development. In summer, the growth is restrained in high temperature period, so it is advisable to control watering, strengthen ventilation and keep the basin soil slightly dry.
2. Generally, the temperature should be controlled at 10 ~ 20℃ before and after the "first frost" enters the greenhouse. In order to delay the flowering period, the temperature can be raised or lowered appropriately. We should try to reduce the humidity in the greenhouse to reduce the occurrence of diseases.
3. Go indoors in winter and cultivate in a sunny and well-ventilated place. If the temperature is suitable, the flowering period can be extended to March of the following year.
