Qingzhou city flower cyclamen seed price is about how much per jin? When will you plant it? How to maintain it? What if the leaves turn yellow?

Cyclamen is also known as radish begonia, rabbit ear flower, rabbit flower, a crown, bonspark, petal lotus, is Primulaceae, cyclamen belongs to perennial herbs. So how much is the price of cyclamen seed per jin? When will you plant it? How to maintain it? What if the leaves turn yellow? It is learned from Jiangxi flower planting base that the price of cyclamen seed is 8-12 yuan / jin, the sowing amount per mu is about 4muri / 5jin, the plant height is 38--68cm, the flowering time is 75m / mu for 100 days, and the flowering situation is slightly different in different places. And the price of cyclamen is 3 yuan, 5 yuan, 10 yuan, 15 yuan and 20 yuan, and the larger one is 30 yuan during the Spring Festival. If the quality is different, the size is different, the price is not the same.

When will cyclamen be planted?

The main results are as follows: 1. The sowing time of cyclamen is determined by the genetic characteristics of the seed, the climatic conditions of the planting site and the market time of the finished product. In the southern region (F1 generation), the large flower type varieties are generally from November to February of the following year, the medium flower type varieties can be postponed by 15-30 days, and the mini type varieties should be carried out between January and March. With the increase of latitude (the average temperature decreases), the sowing date should be advanced appropriately. However, in areas where cyclamen has no obstacles in the summer, the sowing date can be relatively delayed.

2. Sowing and reproduction is one of the common methods of cyclamen reproduction. Cyclamen seeds can only be obtained after artificial pollination. The seeds generally mature in May and should be harvested in time. Cyclamen seeds are larger, with a 1000-seed weight of about 10g and a general germination rate of 85% to 95%. In order to promote seed germination, the seeds can be soaked before sowing, soaked in cold water for 24 hours or 30 ℃ in warm water for 2 hours, then washed the adhesion on the surface of the seeds, wrapped in wet cloth to accelerate germination, kept the temperature for 2 days at 25 ℃, and the seeds could be taken out and sown after a little germination. Sowing time is generally from September to October, sowing seeds in ordinary flowerpots.

How to maintain cyclamen?

1. Soil selection of cyclamen culture.

The culture soil can be prepared with 3 humus soil, 2 forest rotten leaf soil, 2 furnace ash, 2 river sand (sandy vegetable garden soil), 1 mature compost, and properly mixed with calcium superphosphate and other chemicals. This kind of soil, loose and fertile, is suitable for cyclamen to grow. During cultivation, the fumigation method must be used in the cultivation soil, and the high temperature disinfection must be carried out strictly. The cultivation container should be gradually enlarged according to the size of the bulb, and the small seedlings should not be cultivated in large pots.

2. Fertilization methods for cyclamen culture.

Cyclamen like fertilizer, but do not like thick fertilizer, in addition to turning the basin to change the soil to apply some basic fertilizer, generally can be fertilized once every ten days and half a month, pay attention to thin fertilizer diligently. After planting, during the vegetative growth period for several months, organic liquid fertilizer can be applied with a concentration of 1, 6, 1, 8, 1 and 10, and muddy water is used to water the flowers. after summer, if the temperature can not be controlled, fertilizer should be stopped.

3. Watering method of cyclamen culture

Cyclamen can withstand drought. But the soil should be kept moist during the growing season, and pay attention to the fact that there is no water in the basin. Cyclamen does not like soil that is too wet, watering it frequently and less. If summer is not dormant, normal watering can be carried out to keep the basin soil dry. After the Beginning of Autumn, cyclamen entered the period of human reproductive growth, at this time to apply phosphorus and potassium fertilizer. If it is found that the plant is overgrown, apply calcium superphosphate or plant ash extract to control vegetative growth. promote flower bud differentiation, bud pregnancy and flowering.

4. Temperature requirements of cyclamen culture

The suitable growth temperature of cyclamen in winter is 10: 22 ℃, and the temperature difference between daytime and night should be 8: 10 ℃. It can also bloom when the night temperature is controlled at 7: 8 ℃, but the florescence will be delayed slightly, but if it is lower than 6 ℃, it can not blossom normally.

5. Lighting requirements of cyclamen culture

Temperature and light have certain effects on the growth and development of cyclamen. In the whole growth process, it is mainly from the temperature to consider prolonging the florescence. After the flowers are reduced by the end of April, the potted flowers should be removed from the greenhouse and kept in a ventilated and cool place with scattered light. Climate change, suitable temperature and light will also make cyclamen grow a batch of scape and continue to blossom. In the Yangtze River basin and its southern area, the leaves gradually turn yellow after May, which is a reflection of the rising temperature, so watering should be controlled at this time. In summer, conditional cooling equipment should be used to lower the ambient temperature.

6. control methods of diseases and insect pests in cyclamen culture

Cyclamen is vulnerable to aphids, red spiders and leaf curlers in the growing season, so attention should be paid to prevention and control. At the same time, the roots of cyclamen are susceptible to nematode diseases, and pesticides such as carbofuran can be used for basin soil disinfection, with a dosage of 2 grams per pot (0.1% of the soil weight) and mixed into the soil. Cyclamen is also prone to soft rot, leaf spot, fungal atrophy and anthrax. During the onset of the disease, 0.01% concentration of topiramate aqueous solution, or 0.15%-0.2% concentration of thiophanate and chlorothalonil clear water solution can be used for effective spraying.

7. Matters needing attention in cyclamen culture

When the temperature exceeds 28 ℃ in summer, cyclamen seeds begin to dormancy, the dormancy period is not well managed, and the bulbs are easy to dry or rot. How to spend the summer safely is a difficult point in cyclamen cultivation.

It is the best way to spend the summer with strong seedlings. The annual seedlings sown have vigorous growth and weak dormancy tendency in summer. it is necessary to strengthen fertilizer and water management before the beginning of summer to form strong seedlings so as to make the leaves thick, many leaves, thick color and luster. This kind of seedling has strong heat resistance, and it is necessary to do a good job of cooling and dampness reduction at the same time. Cover the sunshade net, increase ventilation, apply thin fertilizer frequently, and spray water around the plant to cool down. After spending the summer in late August, cyclamen enters the growing period, so it is necessary to strengthen fertilizer and water management.

What if the cyclamen leaves turn yellow?

1. When raising cyclamen, we should pay attention to the intensity of light, especially in summer when the light is very strong. In order to avoid the yellowing of cyclamen leaves, shading should be carried out.

2. Watering must be appropriate, which is very important. Basically, the soil should be watered after the soil is dry. Do not water too much at one time. Be careful not to spray water on cyclamen leaves too often.

3. Take the seed ball out of the flowerpot, put it in the refrigerator and refrigerate it, and then take it out and replant it in autumn. It can still grow again.
