【摘要】 通过资料收集、访问和实地考察,调研了益智(AlpiniaoxyphyllaMiq.)的产销情况。结果表明:海南是益智的主产区,其种植面积占全国的86% 以上,年产量占全国的93% 以上。近1～2 a内,全国的年需求量估计逾3 500 t,全国的生产量约3 350 t(海南约3 100 t),供求之间有150 t左右的差距。考虑到我国加入WTO后的出口潜力,今后3 a内这一差距还可能加大。预计海南的总种植面积不超过7 600 hm2,总产量不超过3 400 t,是不会出现供过于求的。因此,适度增加种植面积和产量是可行的。更多还原

【Abstract】 Investigations were conducted into the production and market of Alpinia oxyphylla Miq..The results show that the major producing area of A.oxyphylla Miq.lies in Hainan which shares over86%and93%of the total planting area and output in China,respectively.Estimated total annual demands are at3,500tons and output at about3,350tons.Considering the potential export after China joined the WTO,the difference between demand and supply will be even larger.So,the planting area and yield of A.oxyphylla Miq.should be increased.更多还原
