Tamarix chinensis Lour. is a species of shrub and shrub of the family Tamarix, 0.5 to 1.5 m high, bark grayish brown, branchlets reddish-brown, leaf-scaled. Flowers small, pink, terminal racemes. Fruit. It is widely distributed in Dongying City, Shandong Province, especially in the heavy saline-alkaline zone of Bohai Bay. It is a large-scale bush-like distribution and is a pioneer species of beach natural shrubbery. In the Yellow River Nature Reserve, there are 675 hectares of natural Tamarix forest. The main root depth of Salix psammophila is 1.5 to 2 m, lateral roots spread 1 to 1.5 m, and budding begins in early March and flowering takes place from May to November. Tamarix is ​​a salt-secreting plant. Leaves and twigs can excrete the salts absorbed in the plants. They are strong salt-tolerant tree species with a salt tolerance range of 0.7% to 3%. No matter whether it is a high altitude area or a low-lying saline-alkali land, Tamarix The dominant species. As Tamarix is ​​water-resistant, salt-tolerant, and barley-resistant, and has a long flowering period, beautiful flowers, and pruning, it can be planted as a hedge at the lakeside, on the roadside, and on the floodplains. Tapioca breeding methods include cuttings, sowing, layering and propagation.
1 Cuttage Seedlings use 1 year old shoots with a diameter of about 1cm as cuttings, and cuttings with a cut length of 25cm can be cut in spring and autumn. Using flat bed cutting, bed width 1.2m, row spacing 40cm, spacing of about 10cm. It can also be inserted in bundles, inserting 2 to 3 cuttings per bundle. In order to improve the survival rate, ABT rooting powder 100mg/kg can be soaked for about 2 hours before cutting. Immediately after cutting, water is poured, and once every 10 days, the survival rate can reach 90% or more.
2 Sowing seedlings
2.1 Seed collection and treatment The mature period of Tamarix seeds is from July to November. When the fruit matures, the peel is cracked, the seeds are small, and they are easy to fly. Therefore, when the loquat fruit turns from green to yellow, and a few fruits are cracked, the plants with robust individuals and luxuriant flowers are harvested in time. The collected pods were air-dried, the peel was cracked, and the impurities were removed to sow.
2.2 Selection of nursery land Tamarisk is not strict with the soil and it is resistant to drought, water and salt and alkali. However, in order to cultivate the whole seedlings and strong seedlings, it is better to choose fertile soil with loose soil and loose sand and loam, flatten the land, evenly spread a layer of organic fertilizer, and arrange the seedbeds, which are about 1m wide.
2.3 Seedlings will generally be planted in the summer and can also be planted in the spring of the following year. Water before sowing, soaking the bed surface, and then spread the seeds evenly on the bed. Because the seed is small, it can be mixed with sand and sowed, usually about 5g/m2, covered with thin fine soil or fine sand, or it can not cover, allowing it to infiltrate the soil with water and make close contact with the soil. Most of the seeds germinated 3 days after sowing, and seedlings emerged in about 10 days.
2.4 During seedling management, watering should be paid attention during the seedling emergence. Water should be poured once every 3 days to keep the soil moist. After the seedlings are flushed, the number of irrigations can be reduced and the amount of irrigation can be increased. Seedlings can grow to 50-70cm in 1 year and go out of the garden directly.
3 Batten propagation Select and grow strong plants. Peel the bark 3 to 4 cm away from the side of the shoot 40 cm away from the ground, expose the formation layer, and then place the stripped bark into the soil. Fix it so that it is in close contact with the soil and water it at the right time. The adventitious roots can be produced in about 5 days. After 10 days, they are separated from the mother plant and transplanted.
4 Traits of Tamarix ramosista are generally distributed in clusters. There are approximately 100 branches in a cluster of Tamarix. Before spring buds of willow, it can be rooted, and a cluster of tamarisks can be divided into about 10 and then replanted. This method requires a certain period of time to develop normally.
As a hedge, Tamarix is ​​pruned and can be made into a variety of beautiful shapes. It is easy to cultivate and does not need to change soil. It has been greatly promoted in Dongying City.
