Rust of carnation
[pathogen] Uromycescaryophyllinus (Schrank) Wint., belongs to the subphylum of fungal basidiomycetes and monospore rust. The rust fungus is produced by the transferred host. [symptoms] the disease is mainly harmful to leaves, but also to stems and calyx. The injured site initially showed small light-colored protuberant spots, followed by yellow around. When severe occurs, leaves and stems are twisted. During the growing season, a small brown powder pile appears on the back of the susceptible leaf or on the stem and sepals, that is, the summer spore pile of the pathogen, autumn and winter.

Leaf spot of Carnation
There are many kinds of diseases and insect pests that harm carnation. Unsuitable cultivation environment and mismanagement can induce the aggravation of diseases and insect pests. Carnation leaf spot disease, also known as carnation white spot disease, can harm a variety of flowers of Carnation family. [pathogen] Neurosporum caryophyllum (SeptoriadianthiDesm.) belongs to the subphylum of fungal semi-knowledge, Cercospora. [symptoms] the disease damages leaves and stems.

Prevention and control of blight of carnation
Symptomatic stem and root disease. It was infected at the seedling stage, causing root rot and death. After planting, the main stem and branches were infected, and the injured part was flooded, gray when dry, and the stems and leaves above the injured part withered. The pathogen PhytophthoranicotianaeBreda is called Phytophthora tobaccoides, which belongs to the subphylum flagellate fungi. The cyst pedicel protrudes from the stomata, 10-744 microns long, sporangia solitary, oval or ovate, 28.8-67.5 × 12.5-30 microns in size.

Seedling cultivation of Carnation
Propagation method Carnation cut flower production seedlings can be propagated by cutting, striping, tissue culture and other methods, usually mainly by cutting. Cutting can be carried out at any time except in summer, but it is suitable to be carried out from January to March, especially from late January to early February, and the survival rate is the highest. It is better to cut in the morning, evening or cloudy day. Through the variety cultivation experiment, the lateral buds (i.e. the 3rd and 4th buds) of the mother plant with strong growth and good quality were selected as cuttings. When the diameter of the apical bud is lcm, pull down the branch to make

Cross breeding of Carnation
Carnation (Dianthuscaryophyllus), also known as carnation (Carnation), belongs to the genus Carnation of Carnation family. The flower color is delicate and beautiful, and the flowering period of a single flower is longer, so it is an important cut flower plant in contemporary times. Carnation originated in southern Europe, the northern shore of the Mediterranean, France to Greece, now widely cultivated all over the world, mainly in Italy, the Netherlands, Poland, Israel, Colombia, the United States and so on. With the commercial production of carnation, there are many companies specializing in breeding and breeding.

Cultivation and Management techniques of Carnation
Cultivation and management techniques 1. Environmental selection and capital construction according to the characteristics of carnation, the cultivation environment should be clay soil with dry terrain, convenient drainage and irrigation, flat land and low salt content. In winter, the groundwater level is below 80-100 cm, the root system will not be flooded during flood and waterlogging, and the salt content of 20 cm topsoil is less than 0.1%. The soil with high salt content and excessive alkalinity will affect the root growth, and even burn roots and die seedlings, which must be fully leached by Rain Water or deeply flooded to reduce the salt content.

Cultivation Techniques of Carnation
Dianthus caryoPhylus) also known as carnation, carnation family, carnation genus. Due to its delicate color, long flowering period of single flower, good decoration effect, high yield per unit area, suitable for industrial production, transportation, storage, easy preservation, it is the cut flower with the largest cultivation area and the highest sales volume in the world. At present, in addition to Italy, Holland, France, the United States, Colombia, Kenya, Israel and other countries have also become important carnation producing countries, China's Shanghai, Yunnan and other places have also been planted in large quantities, supply domestic and foreign markets.

Planting techniques of Carnation
Carnation is suitable to grow in a relatively dry and ventilated environment. Therefore, it is necessary to reduce the number of irrigation and room temperature in rainy and hot seasons. Carnation is a light-loving plant, so it is necessary to choose a place with plenty of sunshine and ventilation. At the same time, the root system of carnation is shallow, which is suitable for growth in loose, fertile and rich humus. A moist sandy loam with good drainage. If the soil is sticky and heavy, sawdust should be mixed with topsoil. The suitable pH value of soil is pH6.0~7.5. [propagation methods] Cuttage, sowing and tissue culture are commonly used.

Cutting of Carnation in Winter and Spring
Carnation is an annual or perennial tufted herbaceous flower of Carnation family. Its propagation can be carried out by sowing, cutting, striping, tissue culture and other methods, generally using cutting propagation, in winter and spring. Generally speaking, the cutting of carnation can be carried out from December to April of the following year, especially from January to February, when the lateral buds used for cuttings grow healthily and have the best quality; at the same time, cutting during this period can control the flowering of plants in the second year New Year's Day and the Spring Festival. And the survival rate of cuttings in March is also
