Before the establishment of a Paulownia plantation, in addition to other preparations such as the preparation of forestry funds and the preparation of production materials, the pre-preparation work for the Paulownia forest cultivation technology is the technical preparation of the Paulownia forest. It is an important part of the Paulownia forest management plan before forest management. The full completion of this work will directly affect the quality of future forest management.

According to the biological and ecological characteristics of Paulownia, the technical preparation before Paulownia forest management has become the key to determining the success or failure of afforestation and whether it can achieve fast-growing and high-yield Paulownia. Its main contents include: general conditions suitable for Paulownia growth, technical input in the process of intensive cultivation of Paulownia, selection of Paulownia afforestation land, selection of Paulownia forest species, selection of Paulownia varieties, selection of Paulownia seedlings, Paulownia afforestation density, Paulownia afforestation configuration methods, etc. .

The afforestation land of Paulownia is mainly divided into two types: mountainous area and plain area. Under the general conditions for Paulownia to grow, and the site conditions are different, the growth rate is obviously different. According to the characteristics of Paulownia, the reasonable choice of afforestation land is related to the quality of afforestation and the technical key to whether the fast-growing characteristics of Paulownia can be fully utilized.

The relationship between Paulownia and the environment is a dialectical and unified relationship. The energy and substances required for the growth of Paulownia depend on the surrounding environment. Once you understand the relationship between Paulownia and the environment, you can adjust, control, and try to improve the environment. Conditions to meet the environmental requirements of different Paulownia varieties, better cultivate Paulownia, tap the potential of Paulownia for fast-growing and high-quality, give full play to the ecological benefits of Paulownia, and create more material wealth for the society.

Paying attention to Paulownia afforestation technology is a fundamental measure to improve the quality of Paulownia afforestation, increase the output of Paulownia wood, and reduce the production cost of Paulownia. Only by mastering the paulownia afforestation technology can we create external conditions conducive to the survival and growth of forest trees under artificial control, and achieve the goals of fast growth, high yield and high quality.

Paulownia is quite different from other tree species. Its young tree bark is very thin, it is difficult to heal after damage, and affect the material. It is susceptible to freezing damage and sunburn. The bark rots and wing cracks are not easy to heal after damage, which seriously affects the normal development of the tree. Therefore, strengthening the protection of Paulownia young forests with correct protection methods is an important task in the management of Paulownia plantations.

Paulownia needs to consume a lot of water during the growth process, but different growth periods have different water requirements. Properly mastering the paulownia irrigation method can significantly increase the volume growth of paulownia

Paulownia is very sensitive to soil fertility. Scientific fertilization in accordance with the annual growth and development of Paulownia is an effective measure to reduce production costs, promote early growth of Paulownia young forests, increase Paulownia growth, and shorten the age of Paulownia.

Overgrown weeds are very unfavorable to the growth of young paulownia forests, especially in mountainous areas where root-buried afforestation has a greater impact

Tending and thinning of Paulownia is also called intermediate harvesting or thinning. It is to periodically and repeatedly cut part of the immature Paulownia forest after the paulownia has grown into the forest until the main felling, so as to create good living conditions for the reserved Paulownia forest and promote retention.

The growth and development of the wood, and the thinning of the paulownia wood can be formed into an operation that can be fully utilized as a commodity. Its main task is to adjust the density of forests in a timely manner, improve the quality of forests, wood yield and wood utilization, and enhance the overall resistance of the Paulownia forest.

Pests and diseases are the main enemies of the growth of Paulownia, which can affect the normal growth of Paulownia, and cause the death of the whole plant. In order to cultivate fast-growing, high-quality and high-yield Paulownia forests, especially pure paulownia forests with higher intensiveness, higher density and higher yields, timely prevention and control of diseases and insect pests will run through the entire process of Paulownia forest management, which is one of the Paulownia forest management processes. Extremely critical technical measures

The main pests that harm Paulownia are underground pests, that is, various pests that harm the roots and stems of paulownia; leaf-eating pests, that are pests that harm the leaves of paulownia; branch pests, that are pests that harm the stems of Paulownia. The main diseases are Paulownia witches’ broom disease and so on

Land preparation before afforestation is an important working procedure to improve environmental conditions (mainly the soil conditions) in the paulownia afforestation land, which requires higher specification and quality than farmland preparation. Comprehensive improvement of the site conditions will not only enhance survival rate and growth of the paulownia forest, but also increase the growth quantity of paulownia sapling forest. The practice showed that timber output is greatly influenced by relevant matters (do or do not, careful or careless, time and method) concerning land preparation, where there will be a 1-3 times difference on timber volume per hectare. Therefore, preparing land before afforestation in correct, careful and timely manners plays an important part in improving survival rate, promoting growth of sapling forest and realizing fast-growing and high-yield of paulownia artificial forest, particularly for afforestation in mountain areas.

China has a vast territory, a variety of natural and geographical conditions and climate types. Proper understanding of the basic conditions for optimum growth of paulownia is the most basic requirement in the artificial cultivation of Paulownia. These basic conditions include: temperature, light, rainfall, air humidity, wind and other climatic conditions, soil texture, physical properties of soil moisture, soil nutrition, soil pH, soil salt content and other soil conditions, as well as the groundwater level, the altitude and other site conditions.
