Reproduction points of Robinia pseudoacacia

Robinia pseudoacacia, commonly known as Robinia pseudoacacia, is a deciduous tree, which is widely distributed in China, especially in the Huang-Huai River Basin. The economic value of Robinia pseudoacacia is very high, not only can be ornamental, but also edible, the nutritional value of its nectar is also very high. So how should Robinia pseudoacacia reproduce?

The cultivation techniques of artificial Robinia pseudoacacia can be divided into seedling stage and breeding stage. First of all, the seeds of Robinia pseudoacacia need to be treated in the seedling stage. From July to September every year, the seeds of Robinia pseudoacacia are relatively mature, and the seed pods gradually change from green to reddish brown. In order to ensure the integrity of the seeds, it is most appropriate to pick at this time. After a large area is spread out and dried, the seed coat begins to crack. The brittle outer skin of the seed is removed by manual and mechanical equipment, and other impurities are removed after seed washing to get the cultivated species of Robinia pseudoacacia. In order to get a fast and neat seedling emergence effect, the cultivated species need to be soaked in ① hot water repeatedly, when the breeding is relatively hard, soak repeatedly with hot water of 80 degrees Celsius, after it expands, put Cuiya in a humid environment. ② soaked the seeds in sulfuric acid for 30 minutes, washed them and soaked them in water for 12 hours, and then soaked them in water for 12 hours; ③ buried the fine sand and seeds for about 2 months in a humid environment of about 10 degrees Celsius. Secondly, it is necessary to sow Cuiya's seeds, and the sowing time is usually in spring. When raising seedlings through the seedling bed, the sowing amount is 22.5 ~ 37.5 kg/hm2 in bed sowing and 45 ~ 60 kg/hm2 in ridge sowing. Sufficient bottom water should be irrigated before sowing, and the thickness of soil cover is about 0.6 ~ 0.8 cm. Thirdly, the management during the seedling period is particularly important, because the seed is unearthed for a short time, so it is necessary to ensure that the soil and water is moist during the seedling period to prevent the emergence of similar hardening phenomenon on the ground, but it is also necessary to irrigate reasonably and not to soak the seedlings. After about 4 weeks, a pest control, soil loosening and weeding operation can be carried out, during which the weak leaves in the seedlings can be removed to ensure the photosynthesis during their growth. After that, when the seedlings are close to 1 meter or so, the seedlings can be fixed, and then fertilized before July. Finally, during the growth of Robinia pseudoacacia, fertilization, irrigation, weeding and other operations were gradually reduced to ensure its natural growth.

The breeding of Robinia pseudoacacia is no longer irrigated after August to enhance Lignification and improve the ability of anti-draining and overwintering. The seedlings of Robinia pseudoacacia can be selected in the current year, but in order to keep the roots of the seedlings in the range of 15-20 CM, they can be planted in spring. In order to improve the survival rate, it is necessary to carry out chemical treatment on the roots of the seedlings. According to the previous data, the survival rate of the seedlings soaked in naphthalene acetic acid for more than 12 hours can reach more than 80%, but it should be noted that each seedling needs to have a certain distance, and the distance of 45CM is relatively moderate. The treatment can cultivate Robinia pseudoacacia forest. In addition, there are some methods, such as asexual reproduction, grafting seedling, root planting and so on.

As the surviving Robinia pseudoacacia has strong adaptability, there are no strict requirements for soil cultivation and afforestation methods. Once the young forest is formed, as long as the young forest is regularly fertilized, weeded and insecticidal, the Robinia pseudoacacia forest can flourish, but it should be noted that the growth peak of Robinia pseudoacacia is in July, so fertilization is most appropriate in June. In addition, the seedlings are easy to drain, so the August harvest should strictly control the water, enhance Lignification and reduce the damage caused by draining.

Arrangement of key techniques for raising seedlings of Robinia pseudoacacia

Content Abstract: Robinia pseudoacacia, belonging to the butterfly flower family, has a slightly high tree type and compound leaves, which can be used in medicine as a whole, thus improving the planting value of Robinia pseudoacacia. The next thing I would like to share with you in this article is which one is good for the seedlings of Robinia pseudoacacia, and the key points of raising seedlings of Robinia pseudoacacia.

[which one is better for Robinia pseudoacacia seedlings]

The market price of Robinia pseudoacacia is on the low side, but the price of Robinia pseudoacacia is unstable because of the distinction of producing area and variety, and the purchase of small seedlings of Robinia pseudoacacia should go directly to the seedling base approved by the state, both the price and variety are reliable.

▌ Shandong Golden Century Seedling Base

The base always ranks among the best, integrating production, research and training. Belongs to the local agricultural economic development leader.

▌ Shandong Shuihu Seedling Base

Address: Yuncheng, Shandong

Shuihu seedling base, which specializes in cultivating young seedlings of Robinia pseudoacacia, is the first choice for the propagation of small seedlings of Robinia pseudoacacia in China, introducing professional planting and maintenance techniques of Robinia pseudoacacia. The seedlings have the advantages of high survival rate, strong resistance to diseases and insect pests, easy maintenance and mature wood. The cultivation area of Robinia pseudoacacia seedlings in China has reached more than one thousand mu.

[key points for raising seedlings of Robinia pseudoacacia]

The seedlings of Robinia pseudoacacia mainly choose many methods, such as sowing, cutting, root burying, grafting and so on, but the key factor for the success of raising seedlings lies in the maintenance and management in the later stage, and there are the following key points that need to be paid attention to.

▌ seed

First, the time of seed collection must be controlled in autumn, such as October and November is the best season choice. Second, after seed collection, seed rubbing must be carried out to remove the seed coat of Robinia pseudoacacia, which can improve the survival rate. Third, the treatment of Robinia pseudoacacia seeds before sowing is necessary, and the seeds used in sowing must be in the shape of a grin.

▌ thin film

No matter sowing, cutting, or grafting, thin film must be used when raising seedlings, which can be used for water control and can effectively prevent seeds from being damaged by diseases and insect pests during germination.

Before the hot weather comes, it is necessary to lift the film in time to avoid burns on the roots of seedlings and to allow photosynthesis in the roots of Robinia pseudoacacia in time.

▌ interseedling

When the Robinia pseudoacacia tree is propagated by sowing, after the film is opened, it is necessary to start the work of seedling replacement and seedling replacement immediately to ensure that the distance between each surviving Robinia pseudoacacia seedling is about 15 cm. The seedlings that are too dense are removed, and the vacancy needs to be filled.

Main points: the seedlings of Robinia pseudoacacia trees are best in wild conditions, and they can be fertilized properly without watering. Secondly, the seedlings used for transplanting do not need to be pruned, and generally need to be aimed at more than 3-year-old Robinia pseudoacacia trees before they can begin to prune and shape.

Planting techniques of Robinia pseudoacacia in autumn and winter

Robinia pseudoacacia is widely used in landscaping because of its strong adaptability, but it is found that some Robinia pseudoacacia do not grow vigorously after planting. Technical points of Robinia pseudoacacia planting in autumn and winter:

First, planting time: plant as soon as possible after all the leaves have fallen in November every year.

Second, seedling specifications: generally, seedlings with a ground diameter of more than 1 cm are selected for afforestation in barren mountains, and large seedlings with a ground diameter of more than 2.5 cm are selected for afforestation on the four sides, and the complete root system should be retained when planting, with a root width of not less than 20 cm and a length of not less than 25 cm.

Third, planting method: adopt the method of planting along with digging holes. When digging holes, separate the upper mature soil from the bottom raw soil. The planting depth is the same or slightly deep as the burying depth of the seedlings. When filling the soil, you should first fill the cooked soil and then fill the raw soil.

Fourth, precautions: before planting ①, we should pay attention to trim the root system, and cut off the rotten root and split root. The stem of ② can be cut along with planting, or it can be cut off again after 7 days of planting. The height of ③ truncation is 3-5 cm from the ground. After the cut, the soil should be cultivated and buried.

Planting at the end of autumn and the beginning of winter, first, immediately following the rainy season, the soil moisture is better than that of spring plum, which is conducive to root growth; second, the root system has been restored and grown for a period of time before the advent of severe winter, and the slow seedling period in the next spring is short, and the root system grows when the temperature is suitable. New buds germinate quickly and grow into new branches, thus improving the survival rate of planting.
