First, tree species hedgehog. The root of Robinia pseudoacacia can directly fix nitrogen, and it is a pioneer species of sand-alkali land for afforestation, but it is not suitable for planting on poorly-drained low-lying land.
weeping willow. Xi lived in wetlands and watersides and was moderately salt tolerant. It can be used as an important protected forest tree species in saline land.
Semolina. It is one of the fast-growing tree species of sand-alkali land. It is resistant to water and moisture and suitable for growing on mild sulfated land. It can be planted on both sides of rivers and canals and saline-alkali depressions in the area along the river in the base of eucalyptus, and should be used as a pioneer species and firewood forest. It is also a good tree species for farmland shelterbelts.
Skunk. Rapidly growing, it is a pioneer species for afforestation at the initial stage of saline-alkali land, and can be used for wind protection and wind protection. It can be planted on both sides of the road and on both sides of the road.
Bitterness. Salt resistance is second only to the hedgehog, and it can grow on dry and thin saline-alkali land with less pests, rapid growth and strong sprouting power.
Populus tomentosa. It grows well in fertile and humid areas, and it can grow normally in light-alkali areas, and it can tolerate short-term flooding. It is suitable for fast-growing and high-yield forests, farmland shelterbelts and fine tree species on all sides.
Hybrid Yang. Such as Zhonglin 46 Yang, 69 Yang, etc., in the soil salt content of 0.5%, perennial groundwater level of less than 1 meter, the rainy season there is a case of stagnant water growth is normal, for the timber forest, shelterbelts, greenery on all sides of good fast-growing species.
White. Salt-tolerance is better when the soil salt content does not exceed 0.4%. Can do timber forest, farmland shelterbelts and greenery on all sides.
mulberry. Salt and water resistance are strong and can be planted on both sides of farmland shelterbelts.
Pear tree. It is one of the hardy, tolerant and moderately salt-tolerant species of fruit trees, such as the use of Du Pear as the rootstock for grafted pear trees, which is more resistant to alkalescence. Can grow on soil with 0.6% salt content.
apricot. One of the most salt-tolerant alkaline fruit trees.
jujube. The requirements for the soil are not strict, except for swampy land and heavy alkaline land, can be cultivated. The ability to adapt to the pH of the soil is very strong, and there is no strict requirement for the level of the groundwater level. Even in the case of 30 cm to 70 cm of water, the growth still has no significant effect in the case of 30 days.
Paulownia. Suitable for the growth of sand-alkali land, mainly as a farmland shelter forest, but afraid of flooding, not wet.
Second, bush species Amorpha. With rapid growth and strong adaptability, it can be used as a low-level forest in the windbreak forest belt in the saline-alkaline sand region. It grows well when the soil salt content is 0.4%.
Wax strips. Can grow on low-humidity soils with 0.2% to 0.5% salinity. Green trees can be planted on all sides and white wax can be cultivated. Flooding can still survive many days.
Wei Liu. It is drought-tolerant, water-resistant, highly saline-alkali-resistant, windproof, sand-fixing, and bank protection. Saline-alkali areas can be planted on both sides of the channel and on saline-alkali land where vegetation is not produced.
Liu Liu. Deciduous shrubs, which grow rapidly, have strong adaptability, and are resistant to mild saline-alkali, can fix sand and protect shore. It is suitable for planting in mild saline-alkali wetlands, alkaline floodplains, plain slopes, and sand-alkali wasteland.
