Potted shrimps are usually propagated by cutting. Except in hot summer and humid period, it can operate all year round and is easy to survive, especially in spring and autumn. Generally, after the full flowering period in June, combined with shaping and pruning, the robust branches of that year are selected as cuttings, and a leaf is removed and inserted into loose substrates such as plain sand and vermiculite. After insertion, cover with a film, keep warm and moist, and shade, and you can take root, plant in time, and bloom in the next year. The flowers in Xiayi are short and pointed, wedge-shaped and entire. The base is much branched, with short and rough hairs. Entire, with short hair on both sides. Spikes droop, with short hairs outside, lip-shaped, the upper lip is completely or slightly cleft, and the lower lip is shallowly cleft. Degree: The optimum temperature for cuttings to take root is, ear-borne. When low temperature is encountered after cutting, the heat preservation measures are mainly to wrap the cuttings with film; After cutting, spraying cuttings is inseparable from the sun, because cuttings should continue to feed and take root to supply their rooting needs. However, the stronger the light, the more water consumption in the cuttings, which is not conducive to the survival of cuttings. So be sure to keep out the sun after cutting, and then gradually remove the seeds to absorb water. For common seeds that germinate easily, this work can be omitted. Let the water absorb slowly. For the humidity when pruning by hand or other tools on sunny days, the relative humidity of the air after pruning must be kept at 75% ~ 85%. Cuttings naturally like mild and humid climate and well-ventilated environmental conditions. Its growth is most suitable. The suitable temperature in summer and autumn is about 25℃. Avoid strong winds and scorching sun in high temperature season to avoid wilting and yellowing of stems and leaves, and put them in a cool and ventilated environment to prevent pests and diseases. Visible after the cool autumn. When it is cold in late autumn, potted plants should be moved indoors for cultivation, so that they can fully receive light, and the plants after flowering should be pruned again. Management plants can continue to germinate and bloom. If the room temperature can only be kept in winter, it is necessary to stop fertilization and dry the pot soil slightly so that the plants can survive the winter safely. It is cold-resistant, potted in greenhouse, with loose and fertile shrimp flowers and sandy loam with good water permeability and air permeability. Potted soil. More suitable for pregnant buds to bloom.

Potted soil containing 4 parts humus soil, 3 parts garden soil, 65,438+0 parts decomposed organic fertilizer, 65,438+0 parts sandy soil and fresh sawdust was mixed to form weakly acidic culture soil. Then put some hoof horn pieces and broken bones at the bottom of the pot as base fertilizer, which has long fertilizer effect and is more suitable for its growth and pregnancy.

Potted shrimp should be fully illuminated in spring and autumn. If the plants are shaded too much and the light is insufficient, the stems and leaves will easily grow white, which will not only affect the appearance of the plants, but also affect the quality and quantity of flowering.

The fertilizer and water management of potted shrimp should be appropriate. Shrimp has a long growth period and flowering period and needs more fertilizer and water. Usually, the potted soil is slightly moist, and the decomposed cake fertilizer solution is applied every 7 ~ 10 days. When flowering, phosphate fertilizer can be added to the fertilizer solution to make the flowers more colorful. Pay attention to watering frequently in summer. In order to create a good environment and climate, we can pay attention to spraying water on the surface of the basin, plants and the ground around the basin, especially spraying water and fog on plants, which can make the branches and leaves of plants more tender and colorful and increase the ornamental effect. Spraying water can increase the air humidity in a small range, and also reduce the temperature, which is beneficial to the growth and germination of potted shrimp.

Shading and ventilation of shrimp skin in summer is an important link in shrimp skin culture. During this period, if it is not well maintained, it will make the plants grow poorly, produce fallen leaves and affect flowering. Summer is also the peak of shrimp growth, with colorful and exotic flowers and grasses competing to open. When the high temperature reaches about 35℃ in summer and the sunshine is strong, it is very unfavorable for shrimp to bloom, so it is necessary to do a good job of shading and ventilation for shrimp. Whenever the sun is strong and the temperature rises, the basin end can be placed in a cool, ventilated and scattered place. If there are many potted plants, you can build a shed on the ground to cover the seedlings, and cover them early and lift them later. In the rainy season, it is often cloudy or sunny. Roll up the curtains on cloudy days and cover them in time on sunny days. Although time-consuming and laborious, it is beneficial to plant growth. If shrimp is cultivated indoors, potted plants can be placed in a cool, bright and ventilated place or on a coffee table or table slightly away from the window, and can also grow normally and produce bright flowers. Shrimp skin is planted in the ground, with tall plants, strong branches and very diligent flowering. Therefore, when potted, Qin Ying pruned and reshaped, and cut off the branches that were too long and too high to make the plant short, firm and symmetrical. The cluster of shrimp skin is weak, and the new buds are often white and long, with loose plant posture and few flowers. Therefore, it is necessary to cut it short in time, pick the core moderately, and develop a low and compact plant posture. Perennial plants can also be bound with frames.
