Planting and Management techniques of Sophora japonica what soil is suitable for Sophora japonica

The shape of the locust tree is tall and fragrant, and many people want to plant it, but it is not easy to plant it. Sophora tree is proud and expensive, it needs careful management in planting, and its requirements for soil and other aspects are also extremely high, so how should we plant and manage it? What should we pay attention to in the choice of soil?

Planting and Management techniques of Sophora japonica

1. Select and prepare the soil before sowing, and choose the sunny, fertile, loose and well-drained loam. Turn 60cm deeply, flatten and rake fine, make the border, width of the border 70~100cm, apply sufficient base fertilizer, use mature organic fertilizer 500kg or urea 5kg every 667m, and sprinkle it on the border surface with ring fertilizer 3000kg.

2. Select mature and full seeds, soak the seeds in 70-80 ℃ warm water for 24 hours, remove them and mix them with 2-3 times fine sand, pile them indoors, and pay attention to turning over and adjusting the upper and lower temperature when accelerating germination, so as to make the germination neatly. Generally, it takes 7 to 10 days, and the seeds can be sown when the seed crack is 25% and 30%.

3. Before grafting, one-year-old branches with full growth, no diseases and insect pests and a diameter of about 1cm were selected as scions, cut short into about 10cm, sealed with wax to prevent water loss, and then stored in a cool leeward. In the middle and last ten days of April, after sprouting, the big seedlings of Robinia pseudoacacia with DBH above 3cm and straight trunk were selected, cut dry at the appropriate position and then grafted.

What kind of soil is suitable for locust trees?

The conditions for planting locust trees should ensure sufficient sunshine and maintain appropriate humidity. In addition, although the locust tree does not have high requirements for soil, it will grow better in fertile, well-drained, deep, sandy soil. The neutral sandy loam with fertile soil and convenient drainage and irrigation was selected as the nursery. When preparing the soil, it is necessary to apply sufficient base fertilizer, generally 50 kg of farm fertilizer, phosphate fertilizer and cake fertilizer per mu of land, and treat the soil with 30% carbofuran 0.75-1.25 kg. After ploughing and raking, the flat bed is made into a flat bed 1 meter wide.

What is the distribution of locust trees?

The main results are as follows: 1. Locust trees are native to China and are widely cultivated in the north and south provinces of China, especially in North China and the Loess Plateau, as well as in Japan and Vietnam, wild in Korea, and introduced in Europe and America.

2. The locust tree likes light and is slightly shade-tolerant, can adapt to the cold climate, has deep and developed roots, and is not strict with the soil. It can grow normally under the condition of acid to calcareous and mild saline-alkali soil, even when the salt content is about 0.15%. It is resistant to wind, drought and barren, especially adapting to adverse environmental conditions such as urban soil consolidation, but it grows poorly in low-lying stagnant water and has strong resistance to pollution such as sulfur dioxide and soot. It grows faster when young, and then grows at a medium speed, and its life is very long. the old tree is easy to become hollow, but the life span of latent buds is long, which is beneficial to crown renewal.

The flowers of Sophora japonica usually bloom in a few months.

1. According to the understanding of the acacia tree growers, the florescence of the locust tree is from July to August. Locust trees are often planted on the edge of houses and roadsides, and are widely cultivated in all parts of China, mainly in the north, especially in the Loess Plateau and North China Plain. They generally bloom from April to May every year, and the flowering period is about 10 to 15 days.

2. Flos Sophorae, also known as Sophora japonica, is the flower of Sophora japonica in Leguminosae. It has many flowers, raceme, light yellow, butterfly Corolla, cluster when in full bloom, overlapping drape, can be cooked and eaten, can also be used as traditional Chinese medicine or dye, can be used as medicine, has cool convergence, hemostasis and antihypertensive effect, and is also an important honey source plant.

3. Before sowing, the basal fertilizer (mainly organic fertilizer or circle fertilizer) 3000kg is applied per mu of the seedling land, and the available nitrogen fertilizer f such as urea can be applied per mu in the first ten days of June combined with watering. Urea is applied from July to August (it is best to add an appropriate amount of compound fertilizer for 12 to 3 times, and the amount of fertilizer applied each time is about 30kg. After September, there will be no more watering and fertilization to promote the Lignification of seedlings.

In short, the planting of locust trees is not easy, in addition to the high requirements for sunlight, soil and other aspects, want to plant well, but also to understand the characteristics of locust trees, and combined with the local environment, learn the management methods of locust trees. It is hoped that the knowledge of planting locust trees this time can make more people understand locust trees.
