Abstract:

Kuancheng traditional chestnut cultivation system is recognized as an important agricultural cultural heritage in China. The chestnut cultivation in Kuancheng County has a long history and chestnut produced there is well known with excellent quality. To investigate the natural advantages and disadvantages of chestnut cultivation system in Kuancheng from the perspective of soil and climate, this paper analyzed the soil and climatic conditions in Kuancheng chestnut cultivation system based on the observation dataset of basic meteorological station and automatic meteorological stations in addition to the soil data gathered by specialized field sampling in the research area, the comprehensive climatic suitability for chestnut cultivation was evaluated. The results show that the soil in Kuancheng chestnut cultivation system is featured with proper pH, abundant organic matter, high N, K fertilizer and rich Fe, Mg, Mn and other trace elements content. Meanwhile, the solar radiation and heat resource in Kuancheng County are adequate to meet the needs of chestnut growth and fruit ripening, there is suitable precipitation during fruit growth and pretty large average diurnal temperature range during fruit maturity, which is beneficial to accumulation of sugar in fruits. A comprehensive assessment of climate conditions for suitability to chestnut cultivation suggests that most areas of Kuancheng County are well suitable for chestnut cultivation. However, precipitation scarcity in spring could limit chestnut yield in certain extent, appropriate spring irrigation measurement could greatly promote the potential of high-yield and high-quality chestnut production.
