How to cultivate Carnation Culture methods and points for attention of Carnation Culture

Carnation is a kind of plant that likes temperature and light. It grows best in a warm environment. Now carnation is a very common domestic flower, because of its high ornamental value, it has attracted a lot of people's breeding. Presumably many people before breeding, the most want to know is its methods and skills.

How to raise carnations

1. Temperature requirement. Carnation is a cool plant, the optimum temperature for growth and development is 19: 21 ℃, and the temperature difference between day and night should be less than 10 ℃. If the temperature is too high during the day, the carnation will have bad phenomena such as small flowers, narrow leaves and few branches, and the temperature between leaves should not be too high, otherwise there will be abnormal reactions with weak stems, small flowers and good flower color. If the summer temperature is higher than 35 ℃ and the winter temperature is lower than 9 ℃, the plant will grow slowly or poorly or even stop growing.

2. Lighting requirements. Carnations have high requirements for plant light, in addition to seedling or full flowering, there is no need to worry about the adverse effects of strong light on carnations. As a long-day plant, the longer the sunshine, the more it can promote the differentiation of flower buds and bloom earlier. With the help of auxiliary light, it can not only promote the growth of plant internodes and inhibit the growth of lateral branches, but also increase the diameter of Corolla and the freshness of flower color.

Culture method of carnation

1. Soil: clayey soil that requires good drainage, rich humus, good fertilizer retention and slightly alkaline.

2. Watering: carnations grow strongly and are more resistant to drought. In rainy and wet areas, the soil is easy to harden and the root system develops abnormally due to poor ventilation, so attention should be paid to loosening the soil and drainage in the rainy season. Except for timely watering during the growing and blooming season. It is advisable to keep the soil moist by watering less at ordinary times. The air wettability should be kept at about 75%, and proper spraying of water before flowering can prevent the bud from cracking in advance.

3. Fertilization: carnations like fertilizer, apply sufficient amount of baking fertilizer and bone meal before planting, and apply liquid fertilizer continuously during the growing period, generally applying mature thin fertilizer and water every 10 days or so, and applying topdressing after flower picking.

Points for attention of carnations

1. During the vigorous growth period of spring and autumn, it is appropriate to keep the soil moist to meet the needs of growth and development. When the growth is inhibited during the high temperature period in summer, watering should be controlled to strengthen ventilation in order to keep the basin soil slightly dry.

2. In general, when "Frosts Descent" enters the greenhouse before and after, the most suitable temperature control is 10-20 ℃. In order to prolong the florescence, the temperature can be increased or lowered appropriately. Efforts should be made to reduce the humidity in the greenhouse in order to reduce the occurrence of diseases. Enter the room in winter and train in places with plenty of sunshine and good ventilation. If the temperature is suitable, the florescence can be extended to March of the following year.

Disease and insect Pest Control of Carnation

1. Carnation leaf spot

Control methods: when planting, disease-free branches should be selected from strong plants to prevent the first infection of pathogens, and fine-leaf varieties with strong antibacterial ability can also be introduced. After picking buds and cutting flowers, you can choose 8-1000 times liquid of Billi shark, 2000-3000 times liquid of Penicillium, and 75% chlorothalonil 500 times liquid spray, the effect is very good. If the disease occurs during the growing period, diseased leaves or diseased plants should be removed in time, and the above-mentioned agents should be sprayed to prevent the spread of the disease.

2. Rust

Prevention and control methods: if the carnation has rust, it can be sprayed with 2000-3000 times liquid of Penicillium, which has a good control effect, and other agents such as must shark and strychnine can also be used.

3. Botrytis cinerea

Prevention and treatment: pay attention to indoor ventilation and light transmission, reduce humidity. Get rid of the diseased plant in time. Spray 8-1000 times liquid of must shark every 15 days or so, spray 2-3 times continuously, effective and good control effect.

4. Carnations are endangered by aphids and red spiders.

Prevention and control methods: spray with 40.7% EC diluted 1000 ~ 2000 times, 40% dimethoate emulsion 1000 times or 80% dichlorvos emulsion 1000 times.

When raising carnations, we must pay attention to its Wendy. Too high temperature in summer or too low temperature in winter may affect its growth. Carnations are also vulnerable to diseases and insect pests, so it is necessary to strengthen the prevention and control of diseases and insect pests in the later stage of breeding.
