Abstract:

The objective of the research was to analyze the soil nutrient in wile and cultivated Alpinia oxyphylla areas, by determining the soil nutrient. The results showed that soil nutrient content of Alpinia oxyphylla in artificial cultivated area was higher than that of wile area in a small number of areas, however, as was on the contrary in most of the major producing areas of Alpinia oxyphylla. The levels of total nitrogen and potassium were in most areas of growing Alpinia oxyphylla in Hainan, China, but total phosphorus was at or below Ⅲgrade. Available phosphorus and nitrogen content is very low, and available K was in the rich. Available nitrogen mainly was in the ammonium.
