采用田间试验的方法对高粱台中５ 号进行了２ ａ 的试验，结果表明：高粱台中５ 号基本适应海南的生物气候条件，籽粒产量可达３．９ ｔ／ｈｍ２ 。在该试验条件下，３ 要素的最佳配比为：Ｎ１２０ ｋｇ／ｈｍ２ ，Ｐ２Ｏ５ １２０ ｋｇ／ｈｍ２ ，Ｋ２Ｏ７５ ｋｇ／ｈｍ２ 。
A field experiment was carried out to test the sorghum Taizhong 5 for 2 years. The results showed that sorghum Taichung No.5 basically adapted to the bioclimatic conditions in Hainan, and the grain yield could reach 3.9 t / hm2. Under the test conditions, the best proportion of 3 elements is: N120 kg / hm2, P2O5 120 kg / hm2, K2O75 kg / hm2.
