How to cultivate herbaceous peonies?

Herbal peony is not called Ranunculus, celery flower, Persian Ranunculus, land lotus flower, etc., Ranunculus is a perennial herbaceous flower of Ranunculus family, rich in color, flower type like peony flower, but smaller, native to southeast Europe and southwest Asia, introduced by the British in 1596 for artificial cultivation, very common in gardens and cut flowers, let's take a look at how to raise herbaceous peony together!

Herbal peony culture environment

Herbal peony likes cool and semi-shady environment, avoid hot, suitable growth temperature is about 20℃ during the day, 7~10℃ at night, both afraid of wet and afraid of drought, suitable for planting in neutral or alkaline soil with good drainage and fertile looseness. After June, the roots enter dormancy stage. Sexual likes mild climate, fresh and humid air, growth environment sparse shade, not resistant to cold freezing, more afraid of the scorching sun. In most areas of China, summer dormancy, potted requirements rich in humus, loose fertile, permeable performance of strong sandy culture soil.

Herbal peony propagation method

The propagation methods of Ranunculus florus mainly include bulbous propagation, seed propagation and tissue culture propagation. The bulbous propagation has the characteristics of short growth cycle, early flowering, large plant type, many flowers and easy cultivation, but its propagation coefficient is low and its propagation speed is slow, which can not meet the needs of large-scale production. The multiple of seed reproduction is high, the color is bright, but the flowering is few, the growth period is long, if does not take the cooling measure to sow ahead of time, can not flower until March, April, moreover to the cultivation level request is high. Although the propagation coefficient of Ranunculus tuberosus in tissue culture is high and the speed is fast, the requirements for inoculation time and explant selection are strict, the propagation technology is difficult and the cost is high, and there are certain difficulties in actual production. Therefore, the commercial bulbs of Ranunculus chinensis were produced by seeding method, and then the finished bulbs of Ranunculus chinensis were produced to improve the cultivation efficiency of Ranunculus chinensis.

How does herbaceous peony breed?

1. Light management: herbaceous peony is not resistant to strong light and likes semi-shade environment. In winter, the light should be sufficient. In spring, with the increase of temperature and the enhancement of light, moderate shade and ventilation should be strengthened. Herbal peony is a relatively long-day plant, so long-day conditions can promote flower bud differentiation, flowering ahead of time, vegetative growth early termination, early start to form bulbs. Under short day condition, florescence was delayed, but it could promote multiple lateral buds, enlarge crown width, increase flower quantity and further improve pot flower quality. In order to advance or postpone flowering stage, we should regulate long and short days according to actual demand.

2. Water management: Ranunculus chinensis likes wet and fears waterlogging, and is more drought-tolerant, but it is not suitable for excessive drought, especially in the late stage of growth. Excessive drought will cause Ranunculus chinensis to enter a forced dormancy state and lead to poor bulb quality. After planting, water should be poured for the first time, and then watering should be timely, and pay attention to balance, and not too dry and wet. The degree of watering should be dry soil surface, and leaves do not appear wilting phenomenon is appropriate.

3, fertilizer management: ranunculus flower planting before the selection of decomposed cake fertilizer or animal manure and other organic fertilizer as the base fertilizer, and spread evenly. After transplantation, when the plant grows obviously or new leaves grow out, topdressing begins, and the fertilizer concentration is 0.1% at the initial stage and 0.15~0.2% at the later stage. 46% urea and 45% water-soluble compound fertilizer were used alternately. Urea is the main fertilizer in the early stage, compound fertilizer is the main fertilizer in the late stage, and it is applied once every 7 days. In winter, compound fertilizer containing nitrate nitrogen should be used as much as possible, and compound fertilizer containing chlorine should not be used. After anthesis, liquid fertilizer mainly composed of potassium was applied 1~2 times to promote the enlargement of bulbs.

4, temperature management: Ranunculus likes cold environment, the best growth temperature during the day is 15~20℃, at night is 7~8℃. The temperature should not be too high or too low, and the temperature difference between day and night should not be too large, otherwise the growth and development of Ranunculus chinensis will be affected, resulting in the decline of flower number and quality. In the production process, the highest temperature in the plastic greenhouse should not be higher than 22℃, and the lowest should not be lower than 0℃. Generally, it is better to use a layer of shed to cover the growth in winter. After planting, normal temperature management can be carried out when the heart leaves grow obviously.

5. Flowering management: After flowering, pay attention to adjusting the temperature in the shed to 15℃ to prolong flowering. Broken flowers and diseased plants should be sorted out in time. Water should be balanced and not too dry or wet.
