Introduction of cornflower cultivation management : Cornflowers have a sunny, cool climate, avoid hot summers, and should be fertile and loose. Because of the straight root nature, it should be live. Autumn sowing is early flowering, wintering in the cold bed, and flowering in the late spring. Because cornflowers are not resistant to transplantability, they must be brought with soil during transplanting, otherwise it is not easy to slow down the seedlings. After being planted, the decomposed manure urine of 5 times water is applied every 10 days or during the fighting month, and the fertilization is stopped until March of the next year. If the potted plants, the potting soil should be loose and fertile, the most used garden soil rot leaves, grass ash and Other mixed soil, when the seedlings have 6-7 leaves, the first transplant; after the growth, at least to the three-barrel In the middle, because the cornflower is a straight root system, the seedling is not resistant to transplanting. In winter, it can be buried in the soil for the winter, and it should be taken out in early March. Fertilization should be done until the flower buds appear. It has strong cold tolerance and can be planted in the east of China. It should be covered in winter in North China; it is fertile and loose in soil; it is sunny; it can be self-broadcast; it is adaptable and easy to cultivate. For cut flower cultivation, it is usually used for greenhouse flowering: planting in August, planting in September, and flowering in February of the next year. The warming of the interior is usually planted in August-September, and the open field covers the winter, and the second year is planted in early spring and blooms in early summer. The northeastern region is springing in the greenhouse. Since the roots of cornflowers are straight rooted and have few lateral roots, transplanting should be carried out in the case of seedlings, and seedlings are not easy to survive, so they are often broadcast live in spring. Cornflower can also be self-propagated and propagated. In addition, cornflowers are densely planted, otherwise they will grow poorly. Extended flowering The cornflowers are rich in color and unique in flower shape. They are good materials for planting, potting and cutting flowers. In order to extend the flowering period of cornflowers, in addition to autumn sowing, spring sowing and summer sowing can also be used. If it is planted from April to May, it will bloom from July to October. In July, seeded with mature seeds of the same year, generally blooms after September, and the cultivation of open field can last to frost. Plants planted in the middle and late October will be transplanted into pots for winter, or directly in the pots in August, and will enter the room before winter. In winter, as long as the room temperature is maintained at 8~15 °C, the appropriate amount of water and a small amount of thin compound fertilizer, placed in a sunny place, can also make cornflowers bloom. This method of seeding in stages can effectively extend the flowering period of cornflowers. Cultivation attention Cornflower is strong, cold-resistant, sunny, and requires fertile, loose, well-drained soil. Usually broadcasted in the seedbed in September, the south of Central China can be exposed to winter, no winter protection, transplanted in November or early March. When the autumn seedlings in North China grow 2~3 true leaves, they will be transplanted once, and they will advance into the impotence in winter, and they will be covered with cold-proof materials in winter, and will be planted in the open field in early spring. Base fertilizer should be applied before planting. Because cornflower is a straight root system, it is not resistant to transplantation, and it must be brought with a large soil mass when transplanting. The stems of cornflowers are weak and easy to fall, so the colonization distance should not be too dense. It is necessary to prevent excessive growth and poor ventilation and cause lodging. In the seedling stage, topping is required to promote the multi-branch and dwarf the plant, so that the flowering is more and the plant shape is also beautiful. During the growing period, the liquid fertilizer should be applied once every 20 days, but it should be noted that it is not appropriate to apply more nitrogen fertilizer. Phosphorus and potassium fertilizer should be applied more properly to make the stems firm and bright. At the same time, watering should be appropriate, not too much, the rainy season must pay attention to timely drainage, otherwise it will cause rotten roots, affecting the normal growth of plants. Disease prevention Sclerotinia sclerotiorum: its pathogen is Sclerotinia sclerotiorum. The disease mainly affects the base of the stem. In the case of high temperature, the stem often has water-stained light brown spots. When the condition is serious, the affected area becomes grayish white, and then the tissue rots, and the upper stems and leaves of the plant wither. The disease is in spring and autumn. It is most likely to occur under humid conditions with an ambient temperature of around 15 °C. The prevention and treatment method is to avoid planting the plant too densely; the diseased plant is immediately removed and concentrated incineration; when the condition is serious, the middle and lower parts of the plant can be sprayed with 70% of the thiophanate WP 1000 times.
