Biological characteristics Evergreen herb, root slightly fleshy. Stems very thin, cylindrical, green, clustered and branched. Leaves small, scaly, 3-5 mm long, green, 6-12, clustered, spreading horizontally; scales on main branch mostly stinging. Flowers are small, white, bisexual, scented, 1-4 clustered on short branches of fine hairy branches; flowering occurs from February to June or June to July, and flowering occurs twice a year. The berry is spherical, green and green. It is purple-black at maturity and contains 1-3 seeds. Sex hi warm and moist environment, not strong light and low temperature. In the summer, it is to be cultivated under the shade. The winter temperature must not be lower than 5°C. Avoid water, because the root slightly fleshy, more water easily rotten. It is also not susceptible to drought, especially when new shoots are taken out. Once water is scarce, new shoots wilting and dead, resulting in leafy branches can not grow, and even severe leafing branches fall off yellow and cause the death of the whole plant. Fertilizer is suitable for planting in loose and fertile sandy loam. Potted plants should not be fertilized and watered to make them low in height. Cultivation techniques Asparagus can be sown or bred to reproduce, generally using seeding multiplication. (1) Seeding propagation Mother plants are normally planted in greenhouses, and asparagus seeds mature from December to April. Because the life expectancy of Asparagus fern is short, seeding or sand collection should be performed promptly after the seeds are harvested. The seed coat was removed at the time of sowing and the seeds were sowed in shallow pots or on-demand in pots with an internal diameter of 7 cm. If sowed in shallow basins, the seeds are planted on a 2 cm row spacing. The seeds are pressed into the soil and covered with earth 2-3 mm. Shallow pots are covered with glass and shaded. The temperature is maintained at about 20°C and germinated for about 20-30 days. (2) The 4-5-year-old plants can be propagated in different plants, and the ramets can be planted in early spring. Be careful and minimize root damage. After easing the seedlings, it is necessary to strengthen the management of fertilizers and water to promote the cultivation of new shoots. In this method, the propagation coefficient is low, and the new strains after the ramets are not in perfect shape, so they are rarely used. When the seedlings are about 5 cm high, they can be planted on pots, planted in pots with an internal diameter of 7 cm, and seedlings can also be planted in shallow pots with a spacing of 5 cm. Use soil as the rot leaf soil and half of the sand, and add some ripened manure properly. After the seedlings are soaked, weekly apply thin liquid manure once. When the plants grow to more than 10cm, they are planted in 10-17cm pots, and the basin soil is mixed with 4 parts of loam, 5 parts of rot, 5 parts of sand, 1 part of sand and 1 part of mature manure, and the base fertilizer is applied. Fertilizers should always be applied during growth, and more nitrogen and potassium fertilizers are needed. During the growing season, the asparagus was not able to tolerate direct sunlight, and the light was too strong, which caused the leafy branches to yellow and fall off. Therefore, it is necessary to shade in summer, but not in winter. Wenzhu has a relatively high requirement for air humidity. During the cultivation process, water should always be sprayed on the surrounding ground. The bamboo is cultivated for many years, and it is changed once a year in the spring, and the soil is removed and replaced with fertile new soil. Depending on the growth of the plant, replace the larger pot or use the original pot. Cut dead branches and yellow leafy branches to maintain a beautiful plant shape. Control fertilization, so as not to grow long and pumping growth vines, damage the plant shape, affecting ornamental.
