| 摘 要： | １９９６～１９９９年连续４年在湖北省秭归县进行了脐橙钾肥施用量田间试验。结果表明，尽管各处理脐橙产量年度变化很大，但施钾显著提高产量和经济效益，１９９７～１９９９年施钾平均增产２６．３％～４１．８％，施钾（Ｋ２Ｏ）１２５、２５０、３７５ｋｇ／ｈｍ２年均增加纯利 １０１１０、１５８４０、９９７０元／ｈｍ２，产投比分别为 １９．３８、１５．４０和７．０４；在试验条件下施钾（Ｋ２Ｏ）２５０ｋｇ／ｈｍ２增产效果最好；施钾有提高脐橙外观品质和内在品质的趋势，例如施钾提高或保持单果重、增加果皮厚度、提高维生素Ｃ含量等；但施钾对品质的影响年度间差异较大，尚需进一步研究。 |

| Abstract: | During 1996-1999, 4 potassium application rates, including 0, 125, 250 and 375 kg K2O/hm2 in form of SOP (K2SO4). were applied for studying the effect of K on yield and quality of navel orange.Rrsults showed that the yield varied greatly from year to year, so in order to get correct results it is necessary to keep the experiments for several years. The ob- tained results can be summarized as follows: (1) the highest yield was received from the application of K2O of 250 kg/hm2; (2) K application increased navel orange yield significantly, which could be increased by 26.3%-41.8%; (3) Some of the fruit quality parameters, such as fruit size and Vc content, could also he improved by Potassium applica-tion. |
