معرفی کتاب: کتاب "Paulownia In China-Cultivation and Utilization" توسط دانشمندان انجمن جنگلداری چین (بیجینگ) تهیه شده است و درسال 1986 توسط شبکه علوم زیست شناسی آسیا (ANBS) و مرکز تحقیق توسعه ملی (IDRC) منتشر شده است. قرن هاست چینی ها درختان پالونیا را می شناسند اما تعیین مشخصات علمی آن ها و انتخاب گونه ها و واریته های متناسب با شرایط آب و هوایی و خاک های مختلف، در 30 سال اخیر مورد مطالعه قرار گرفته است. در این کتاب نتیجه فعالیت ها و آزمایشات موفقیت آمیز چینی ها بر روی پرورش گونه ای به نام پالونیا در قالب برنامه های جنگلداری در جوامع روستایی شرح داده شده است. پالونیا در بیش از 1 میلیون هکتار از مزارع چین به صورت تلفیقی با گیاهان زراعی کاشته شده است. موضوع کتاب "Paulownia In China-Cultivation and Utilization"  شناسایی علمی گونه های پالونیا، روش های پرورش و مصارف آن می باشد. این کتاب یک راهنمای جامع علمی و اصولی برای زراعت درخت پالونیا و با هدف توسعه جنگل های دنیا می باشد.

این کتاب شامل 10 فصل با عناوین زیر می باشد:

  • Introduction
  • Taxonomy And Distribution
  • Growth Characters And Ecology
  • Ecological Requirements
  • Breeding
  • Propagation
  • Afforestation And Management
  • Intercropping With Paulownia
  • Major Diseases And Insect Pests
  • Wood Properties And Utilization of Paulownia

بخشی از کتاب:

At the same time the demand for timber, fuel, pulp and paper, and other wood based products con- tinues to increase. Already in many developing countries there is a critical shortfall in the local supply of wood. Thus the attack on the resources of the native forests continues at an ever increasing rate. Add to this the equally increasing pressure to clear forest for agricultural/livestock production, and the urgent need for action becomes clear if calamity is to be averted.

 The, obvious answer is to plant more trees, both to reduce the pressure on the native forests, and to meet increasing demands for wood. However, large-scale afforestation programs are very expensive, and generally beyond the financial means of third world governments. Even when money is available, limited technical knowledge offen results in the failure of such schemes. Whilst large-scale afforestation undoubtedly can play some role in solving the wood supply/sort conservation problem, to hope that it can provide the complete answer is to delude ourselves.

An alternative strategy is to encourage the participation of the rural community in small-scale tree planting. Such a social forestry approach can take the form of village or individual woodlots, or the integration of trees in existing faming systems. This book describes the successful Chinese experience in the use of one tree, Paulownia, in social forestry programs. Already Paulownia has been planted and incorporated into the system on over one million hectares of farmland in China. This planting has helped alleviate the chromic shortage of timber, fuelwood, and animal fodder, and at the same time served to increase agricultural production, and improve soil conservation.

The significance of developing Paulownia

The genus Paulownia is represented by nine species of fast growing timber trees which are indigenous to China. It is very adaptable, widely distributed and extremely fast growing both in south and north China. Presently, the genus is either naturally distributed or cultivated in 23 provinces, municipalities and autonomous regions. It grows equally well on the plains as well as in mountainous regions up to 2,000 m high. Therefore, the genus provides a great potential for extensive cultivation all over China.     Under normal conditions, a 10-year old Paulownia tree can measure 30-40 cm diameter at breast height (dbh) and will have a timber volume of 0.3-0.5 m3. However, under optimum conditions, they can produce useful timber within five to six years. For instance, in Yinjang County, Szechuan Province an 18-year old P. fortunei tree averages about 21.7 m high, has a dbh of 100.5 cm and has volume of 6.65 m3 of timber, thereby having an annual increment of about 0.37 m3. With this kind of high growth potential the cultivation of Paulownia should alleviate the problem of timber shortage in many of China's counties. For example, in Lankau County, Honan Province, Paulownia was planted over a large area from 1963 to 1965 the total area under mixed cultivation had already reached 20,000 hectares. Felling started in 1971 and it yielded almost 148,000 m3 of timber by 1976 for the local people, effectively solving years of timber shortage.

 Paulownia is very adaptable and extremely fast growing. Therefore, there is great potential to develop the trees of this genus in China.
