What are the main cultivation techniques of carnation?
① prepares the land to build beds. In order to avoid continuous cropping land in field cultivation, fields with high topography, thick soil layer, loose texture, rich humus and good drainage should be selected, which should be deeply turned and exposed to the hot sun in order to achieve the purpose of soil disinfection. The mature organic fertilizer and a small amount of compound fertilizer were applied 3 weeks before planting, and the border surface was formed according to the row spacing of 20 cm × 40 cm and two rows of each species. ② colonization. Water the border once before planting, and when the water seeps and the soil is not sticky, it will be planted according to the plant spacing of 20 cm × 40 cm.

Why do carnations go to sleep in the city?
In 1908, a florist from Chicago in the State of Wu went to consult a botanist. He said, "there are many beautiful carnation flowers in my country. They bloom brightly there, but when I get to the city, I get sleepy." Botanists believe that it may be because the air composition in the city is different from that in the countryside. In order to prove his idea, he took all kinds of gases and put them in the glass cover, and then put the flowering carnation inside, only to find out. As long as the cover contains a few millionths of ethylene gas, the blooming carnation will wither down.

Coring and pruning of carnation with cut flowers
1. The coring technology of cut carnation the purpose of coring treatment of cut carnation is to increase the number of branches, increase the number of flowers per plant and adjust the florescence, balance and timely supply of flowers. The main results are as follows: (1) during the coring period, the first coring of carnation is usually carried out about 30 days after planting, when there are 6-7 pairs of leaves in the main stem of the seedling. When there are 5 or 6 nodes on the main stem, the growing point of the stem tip can be removed, and more or less 1 or 2 nodes can be left according to the characteristics of the occurrence of lateral branches of different varieties.

Control of Botrytis cinerea in cut Carnation
Symptoms: at first, the petals appear oval, brown, large and wet spots, followed by gray mildew, petals and whole flowers rot, and can also infect stems and buds. Reason: long-term exposure to low temperature and humid environment. Prevention and control methods: keep the plant dry as far as possible, it is best to use drip irrigation to control fertilizer and water; maintain good ventilation; spray 75% chlorothalonil 500 times liquid, or carbendazim 500 times liquid, use alternately, spray once every 7-10 days; 10% Sukeling aerosol can be applied in the greenhouse in the evening to seal the shed overnight.

Insect pests of carnation with cut flowers
The main results are as follows: (1) Red spider: generally, the high temperature above 25 ℃ (from July to August) is serious, and a small amount has occurred around the middle of April. Control methods: remove litter and weeds, improve cultivation conditions, appropriately increase air humidity, initial stage: spray 40% dicofol EC 1000 times 1500 times, or 40% dimethoate EC 1500 times, or 25% imidophos EC 1000 times, or fenvalerate 800 times, or fenvalerate 800 times, or carbendazine, nisolan, pyridazinone, carbendazim, mifenac, etc.

Control of Sclerotinia sclerotiorum stem blight of carnation
It mainly affected the root and neck of the plant and dried up and died quickly after infection. The pathogen infected the root neck of the seedlings near the soil surface, and brown or dark brown spots appeared at the initial stage, and gradually spread to the periphery. The base of the seedlings rotted and constricted, resulting in lodging. The seedlings with more aging stem base were damaged, and the cortex of the near soil surface was rotten and sticky. The leaves of the diseased plant were pale and drooping, and finally the whole plant withered and died. Control methods: (1) flowerpots and soil should be disinfected before cutting. (2) the plant should be planted in the high seedling bed, and the watering should be controlled so as not to make the basin soil too wet. (3) Disinfection

Prevent the calyx of carnation from breaking
In the cut flower cultivation of carnation (also known as carnation and carnation), a physiological disease-calyx rupture often occurs. The physiological cause of calyx rupture is the growth of petals, which quickly exceeds that of sweet potatoes and breaks the calyx, especially in large rotation with more than 60 petals. In addition, in the flowering stage, calyx cracks often occur due to the increase in the number of petals or flowers and the large temperature difference between day and night. Therefore, low temperature, too much watering or too much fertilizer, especially too much phosphorus, can easily cause calyx rupture. Ways to prevent calyx cleft:
