摘　　要：采用五种不同施肥量的磷钾肥(0. 3、0. 6、0. 9、1. 2、1. 5kg),在新梢进入迅速生长期前对金太阳杏进行灌根,观察记录磷钾肥对金太阳杏叶片的影响,结果表明:随着磷钾肥施用量的增大,叶片中叶绿素含量增加,同时叶宽减小、叶厚增大,但是高肥量(1. 5kg)的磷钾肥对金太阳杏的作用效果不明显,每株施用1. 2kg的磷钾肥对促进金太阳杏叶片生长、提高叶片中叶绿素含量效果最显著。The test adopts five different application amount of phosphorus potassium fertile(0.3,0.6,0.9,1.2,1.5kg). When new tip just enters earlier stage of rapid growth,it is irritated to root of the golden sun apricot. After observation for 100 days,the phosphorus potassium impacts on gold sun apricot blade are recorded.The result shows that,with the increase of the phosphorus potassium application,the content of chlorophyll increases in the blade,at the same time the leaf width increases and the leaf thickness reduces,while large phosphorus potassium (1.5kg) has insignificant effect on golden sun apricot. Irritating the root of gold sun apricot by 1.2kg phosphorus potassium fertile has the most remarkable effect to promote leaf growing and raise the content of chlorophyll.
