Site preparation and planting measures for mixed forests of strip mulberry and black locust in converting farmland back to forest on the plains
Black locust uses pit-shaped site preparation, with a specification of 80 cm by 80 cm by 80 cm, a plant-to-row spacing of 3 m by 5 m, and a planting density of 45 trees per 667 sq m; plant in spring and autumn, apply sufficient base fertilizer before planting, and water after planting; strip mulberry is planted between the black locust, using pit-shaped site preparation, and planted in spring, the rainy season, or autumn.

Detailed Explanation of Key Techniques for Planting Black Locust (Robinia pseudoacacia) in Autumn and Winter
Black locust (Robinia pseudoacacia) is widely used in landscaping for its strong adaptability, but surveys have found that some black locusts do not grow vigorously after planting, and the reason for this is largely related to improper planting techniques. Key techniques for stem-truncated planting of black locust in autumn and winter: 1. Planting time: plant as soon as possible after all leaves have fallen in November each year. 2. Seedling specifications: for general barren hill afforestation, select seedlings with a ground diameter above 1 cm; for roadside greening, select large seedlings with a ground diameter above 2.5 cm; when planting, keep the root system intact

Black locust is easy to establish when planted in autumn, and autumn is exactly the right season for planting
In the past dozen years or so, spring drought has been severe in Lincheng County, with temperatures rising quickly and soil temperatures rising slowly. Especially after newly planted black locust seedlings are watered, the soil temperature remains low for a long time, causing the aboveground parts to sprout and grow while the root system recovers slowly, which reduces the survival rate of black locust. In autumn, by contrast, temperatures gradually drop, transpiration is lower, soil moisture content is relatively stable, and black locust seedlings have accumulated relatively rich nutrients. Tree roots have no natural dormant period, and when the soil temperature is still high, the roots of black locust planted in autumn can still resume growth. As long as the winter frozen soil layer is not thick,

Detailed Explanation of Key Techniques for Sowing and Raising Black Locust Seedlings in Mountainous Areas
Black locust (Robinia pseudoacacia) is one of the main tree species for afforestation and greening in mountainous areas. It is not only an important source of timber for mine props, railway sleepers, vehicles and boats, and farm tools, but also a good nectar plant. 1. Nursery site selection and land preparation. The seedling-raising site should be a sandy loam plot with flat terrain, good drainage, and deep, fertile soil, and should have irrigation conditions. After the seedling-raising site is selected, plowing should be carried out in autumn to a depth of 30 cm. In early spring, harrow finely and level while the soil is still frozen, and at the same time pick out grass roots and stones. In conjunction with land preparation, apply 3000-5000 kg of decomposed stable manure per mu.

Polyploid black locust is a new type of tree species suitable for growing on poor soil
A sapling less than 10 cm long, looking like nothing more than a pea sprout, planted on barren land where nothing will grow, can shoot up to more than 3 m tall in a single year. This is a new type of tree species suitable for planting in China's western regions - polyploid black locust (Robinia pseudoacacia) - successfully cultivated by the Lvyuan Seedling Research and Promotion Center of Changyi City, Shandong Province, together with experts from Beijing Forestry University, using plant tissue culture technology on the basis of introduced foreign tree species. With its excellent drought resistance, salt-alkali tolerance and tolerance of poor soil, it has become a highly favored "golden sapling"

What are the excellent varieties of tetraploid black locust?
Tetraploid black locust was bred by the Forest Tree Breeding Research Institute of the Korea Forest Service and introduced to China in 1997. There are two types, the forage type and the timber type, with five excellent clones in total. Through regional cultivation trials by experts from our university, two excellent clones suitable for the arid and semi-arid regions of Northwest China were selected for two purposes: establishing high-quality forage forests and fast-growing, high-yield timber forests. While retaining the original advantages of black locust as a pioneer afforestation species, such as drought tolerance, tolerance to barren soil and salt-alkali tolerance, these excellent clones also have the following outstanding characteristics: (1

What kind of tree species is the tetraploid large-leaf black locust?
The tetraploid large-leaf black locust is a superior variety selected through years of dedicated research and experimental comparison from among several excellent polyploid black locust clones introduced from abroad. The tetraploid large-leaf black locust is an artificially induced tetraploid plant, characterized by fast growth, large leaves and high biomass. Its leaf width is more than 2 times that of the common black locust, and its compound leaf dry weight, single leaf dry weight and total leaf dry weight are 1.5 times or more those of the common black locust respectively. Compared with the common black locust, the tetraploid large-leaf black locust has a denser crown, thicker branches and a stronger photosynthetic capacity. Tetraploid

Detailed Explanation of the Key Cultivation and Management Techniques for the Black Locust (Robinia pseudoacacia 'Idaho')
I. Propagation Methods The black locust is easy to propagate by root burying, cuttings, or grafting, and can also be propagated by digging up roots. For root burying propagation, select 1-2 year old main and lateral roots of the black locust, with a diameter of 0.3-1.5 cm being suitable. Each mu requires 10-12 kg of seed roots, and each kg of seed roots can be cut into 300-400 segments. Two methods can be used: greenhouse seedling raising and transplanting, and field root burying. The seedling raising time indoors varies depending on the region, and transplanting to the field is done in mid-May. Field root burying is carried out when the outdoor minimum temperature is above 10°C. Cut the

Detailed Introduction to New Tetraploid Black Locust Varieties
The tetraploid black locust (Robinia pseudoacacia) originated in South Korea and belongs to a new polyploid variety of black locust, introduced to China in recent years. Five lines have been introduced and cultivated so far, divided into two types: fast-growing timber type and forage type. Analysis of experimental results shows that, compared with common black locust clones, the tetraploid black locust has the following main characteristics: (1) The fast-growing timber type is similar to common black locust clones, but its fast growth is more pronounced. One-year-old grafted seedlings can reach a height of 3 m with a ground diameter of 3.5 cm; 3-year-old trees reach 5 m-7 m in height with a diameter at breast height of 6 cm-9 cm. An 18-year-old tree reaches 19 m in height with a diameter at breast height of 24.5 cm and a single-tree volume of 0.
