东宁农場在海南島琼文草原区上。是热带作物农业自然环境类型区中最差的一个区。这里生長着一片白茅和少数的耐旱阳性植物;常風大;一年又有七个月左右是干旱期;降雨量少而集中;年蒸發量超过年降雨量;棕紅的粘土,“下雨变成浆,天晴硬如鉄”。当初,我們在这里种下了橡胶,結果,枯的枯、死的死,不死的也未老先衰。这次失敗,引起了一些干部、工人的悲观失望情緒。个別农业技术員打退堂鼓,認为“这里不但不能种橡胶,就是一般造林也不一定能够成功”;刮起了一股“收摊子”的逆風。

As a result, withered, dead and dead, we did not die before. This failure has aroused the pessimism and disappointment of some cadres and workers. Some agricultural technicians have taken a backstage and held the view that “it is not only impossible to plant rubber here, but it is not always possible to succeed in afforestation.”
