利用海南冬季优势积极发展冬季农业

海南岛是我国最大的一块热带地区，是我国最大的冬季天然温室。冬季光温资源丰富，台风、暴雨及病虫危害很少发生，在特别干旱时段，只要加以灌溉，冬种作物便可以在正常的环境条件下生长、发育，产量比较稳定，易获得高产，并且可以冬种的瓜果蔬菜、粮食、饲料等作物种类繁多，可开发利用的冬闲田面积广。在夏季，台风、洪水、病虫等危害严重，进一步开发的潜力已有限，并且一些产品（尤其是热作产品）面临东南亚、南亚及美洲一些国家和地区的激烈竞争，为此，利用冬季优势，积极发展冬种瓜果蔬菜及饲料等作物，是实现农业高产、优质、高效的关键措施。

USING THE WINTER SUPERIORITY OF HAINAN TO ACTIVELY DEVELOP THE WINTER AGRICULTURE

Hainan is the biggest tropical region and the biggest natural winter green house of China.There are rich light and warmth resources and seldom typhoon, rainstorm, and plant diseases and insect pests. In the special dry time, winter crops can normally grow under suitable irrigation and their yields are also stable and high. The varieties of the melon, vegtable, grain and forage crops that can be planted in winter are rich. The area that can be used in winter is very large. It is the key measure that the winter agriculture is actively developed by using the winter superiority to realize high-quality and efficient agriculture. For in summer typhoon,floods and plant diseases and insect pests are all serious, the potentiatity of the resoures development is limited and the products of tropical crops are facing keen competition from some countries of southeast Asia, south Asia and America.
