Embodiment 1

[0015] In the experimental area of ​​Ehuangzhang Nature Reserve in Guangdong Province

[0016] In March, the annual leaves of adult Diren plants were collected from the experimental area of ​​Ehuangzhang Nature Reserve in Guangdong Province, and the 0.5-1.0cm long petioles with leaves were taken. The petioles were soaked in the rooting solution for 10 minutes and then cut into the local open-air agriculture. In the soil, the petiole is obliquely inserted into the soil, and the leaves stand on the soil surface. Keep the ambient temperature at 18-32°C and the humidity at 50-95%. Adventitious buds and adventitious roots can be induced to form new plants, and the survival rate can reach more than 90%; the rooting solution contains 5 mg of naphthaleneacetic acid (NAA) and 5 mg of indole-3-butyric acid (IBA) per liter, and the balance is Water, its preparation method is: dissolve 5mg of naphthaleneacetic acid and 5mg of indole-3-butyric acid in 1L of water.

[0017] Then transplant...

Embodiment 2

[0019] In the experimental area of ​​South China Botanical Garden, Chinese Academy of Sciences

[0020] In April, the annual leaves of adult Dixiong plants were collected from the experimental area of ​​the South China Botanical Garden of the Chinese Academy of Sciences, and the petioles with leaves 0.5-1.0cm long were taken. The petioles were soaked in the rooting solution for 10 minutes and then cut into the local open-air agricultural soil. It is inserted into the soil obliquely, the leaves stand on the soil surface, keep the ambient temperature at 18-32°C, and the humidity at 50-95%, water every two days to keep it moist, water 3-5 times in total, and adventitious buds can be induced in about 30 days and adventitious roots to form new plants, and the survival rate can reach more than 90%; the rooting solution contains 5 mg of naphthaleneacetic acid (NAA) and 5 mg of indole-3-butyric acid (IBA) per liter, and the balance is water.

[0021] Then transplant it after the rainy...

Abstract

The invention discloses a method for propagating melastoma dodecandrum lour in a cuttage mode through a petiole. From February to May every year, the petiole of the melastoma dodecandrum lour is taken, soaked in an auxin solution and then inserted in the soil, the environmental temperature is kept at 18-32 DEG C, the humidity is kept in the range of 50-95 percent, the petiole is watered to keep humid, an adventitious bud and an adventitious root are directly induced, and a new plant is formed; the auxin solution contains 5 mg of naphthylacetic acid and 5 mg of indol-3-butyrate per liter, and the balance is water. According to the method for propagating the melastoma dodecandrum lour in the cuttage mode through the petiole, no nutriment needs to be sprayed in the seeding cultivation process, time is saved and cost is reduced compared with a common seedling cultivation method, and seedlings can be cultivated in a large scale. Petiole cuttage is usually applied to succulent flowers, it is especially creative to carry petiole cuttage for propagation of the melastoma dodecandrum lour of the common melastoma herb family, and studies on rooting powder and the planting density are also carried out, so that the method has practicability, operability and application and popularization value.

Description

Technical field: [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for propagating dills by using petiole cuttings. Background technique: [0002] More and better available native plants need to be developed for road slopes, soil erosion areas, open land and forest greening in tropical and subtropical areas. However, Diren is a good variety worthy of popularization and application in long-term field observation and applied research. How to breed seedlings better is one of the problems to be solved. [0003] Melastoma dodecandrum Lour. is a perennial evergreen plant of the Melastoma dodecandrum Lour., also known as wild eggplant, ground pomegranate, paved brocade, and ground red. Diffuse or creeping subshrubs. The bald branches are generally thinned and coarsely haired, the stems are branched and the lower part is lying on the ground, about 10 cm long. Its leaves are opposite, ovate or elliptic, 1-4 cm long and 1-3...
