Tamarix is ​​a deciduous shrub or small tree of the genus Tamarix, which is native to China and has a wide distribution, ranging from North China to the middle and lower reaches of the Yangtze River, south to south and southwest. Tamarix striata is widely used in landscaping, extensive in management, and has strong salt-tolerant capacity.
Biological characteristics Tamarix is ​​as high as 5 to 8 meters, the bark is red-brown, and the shoots are slender and drooping with purple. Leaves ovate-lanceolate, closely arranged on branchlets. The flowers are pink and bloom in summer and autumn. Sometimes they bloom three times a year.
Xiliu hi light is not tolerant to yin. The roots are well-developed. They are both dry and resistant to water, strong in wind resistance, and resistant to saline and alkaline earth. They can grow normally on salty grounds with 1.2% salinity.
Propagation methods Tamarix may be propagated by cutting, sowing, buckling, and ramification. But cutting and sowing are the most common.
1. Cutting and cutting propagation can be carried out in spring and autumn. One-year-old shoots with a diameter of 1 cm were selected as cuttings on a robust, disease-free plant with a cutting length of 15 cm. The nursery beds are flat beds, 1.5 meters wide, spaced 50 centimeters apart and 15 centimeters apart. Before cutting, use ABT rooting powder with cuttings, insert and drench water, then water once every 8 days. Before the winter cutting seedlings should be covered with soil or set up insulation sheds for winter; spring cutting seedlings can be up to 1 meter in the year.
2. Seeding and sowing are generally performed in the spring. The nursery should choose fertile soil and sandy sandy loam with good permeability. Before the planting, the soil should be leveled and a layer of organic fertilizer should be used as a base fertilizer. Harvest seeds from vigorous plants and store them in shade. Soak the bed surface before sowing, and then spread the seeds evenly on the bed surface. Can be mixed with appropriate amount of sand to sow, sowing and then spread a layer of fine soil cover, about 8 days Qimiao. During the emergence, watering should be taken care of to keep the soil moist. The seedlings can grow to 50 cm in height in the current year and can be used directly in the garden in the late autumn or the following year.
There are two types of plants that are commonly used in gardens to trim the tamarisk trees, namely natural shrubs and small trees.
1. Natural shrubs are relatively simple to prune, and the branches can be allowed to grow naturally at the early stage of cultivation, with emphasis on the protection of flat branches. Timely sparse dense branches, stem branches, diseased branches and old branches, and at the same time sparsely cut out large branches to promote their multiple middle and small branches, forming a good shrub shape, to achieve the best viewing state.
2. Small arbors choose to stand upright branches for the main culture, other branches are all removed. The selected branch was short-cut and kept at a height of about 40 cm. On it, a branch with strong erection was selected as the trunk extension branch culture. After growing to a certain height, two or three uniformly distributed branches are selected as the main branch, and the main branch is short-cut at the end of autumn to cultivate the side branches, and the useless branches on the side branches are removed in time. After years of training, basic trees can be formed. In the future management, only redundant branches, dense branches, diseased branches and excessive branches will be eliminated.
Although the water and fertilizer management of tamarisk is resistant to extensive management, in the first three years of planting, careful water and fertilizer management is very necessary, which can accelerate the growth of plants and help form a good plant shape. When planting, some fermented ring fertilizer should be applied as base fertilizer, and the base fertilizer should be evenly mixed with the cultivated soil. At the end of autumn, some circulatory fertilizers can be applied; at the end of the second year, some three-element compound fertilizers can be applied at the end of autumn, and ring fertilizers can be applied at the end of autumn; the third year can be applied according to the method of the second year. From the fourth year on, if the plants grow normally, they can apply less fertilizer or no fertilizer.
After planting T. velutipes, it should be poured with water immediately. After 7 days, it should be poured into 2 waters. After 10 days, it should be poured into 3 levels of water. Afterwards, depending on soil moisture, the general principle is that Ningshui should not be dry, but water should not accumulate. At the end of autumn, poured enough water to seal frozen water. The thawing water will be poured in the early spring of the next year. After that, it will be poured once a month, and the frozen water will be poured in the late autumn. The third year is watered according to the second year method. After entering the normal management 3 years later, it is only necessary to rely on natural rainfall. If it is not a long-term drought, no special watering is required.
Pest control The common pests of Tamarix lucidum are Pyriacidae, Pterocephalus sinensis and P. sinensis. If there is harm to Pyralidae, it can be sprayed with 800-1000 times of the trichlorfon during its larval period; if it has occurred, it can be killed manually, and it can also be used as 200 times. Spraying is performed; if there is a small-spotted codling moth, black light can be used to trap the adult, or 80% of dichlorvos EC can be injected from the larval excretion hole to eliminate the larvae.
Seedling blight is the main disease of Tamarix. To prevent and treat this disease, it is necessary to start from the seedling stage. Dilute the seedlings with a 400-fold dilution of 40% formalin and sprinkle them on the seedbeds. Disinfect the nursery bed. Alternatively, use 25% carbendazim before seeding to seed the seedlings. Afterwards, it can be sprayed once every 10 days with equal amount of Bordeaux mixture and sprayed three times for prevention.
