广西龙眼主栽品种丰产园果实及叶片的营养状况

Nutrient status of longan leading varieties in fertility orchards in Guangxi

对广西三个龙眼主栽品种“大乌圆"、“石硖”和“储良”进行果实性状和营养成分、叶片N、P、K含量分析，结果表明：各品种果实营养成分之间及其与叶片N、P、K含量之间有一定的相关性；初步提出广西丰产龙眼叶片N、P、K含量范围：“大乌圆”1.5×10-2～1.9×10-2, 0.08×10-2～0.12×10-2，0.48×10-2～0.64×10-2；“石硖” 1.5×10-2～1.7×10-2，0.09×10-2～0.10×10-2，0.39×10-2～0.56×10-2； “储良”1.4×10-2～1.8×10-2，0.08×10-2～0.11×10-2，0.38×10-2～0.62×10-2。

The nutrient ingredients and quality characters of fruits, N, P, K contents in leaves of longan leading varieties Dawuyuan, Shixia and Chuliang in Guangxi were analyzed. The results showed that there was a definite correlation between nutrient ingredients of fruits and N, P, K contents in leaves. The ranges of N, P, K contents in leaves of longan varieties in fertile orchards were Dawuyuan 1.5×10-2～1.9×10-2, 0.08×10-2～0.12×10-2, 0.48×10-2～0.64×10-2, respectively; Shixia 1.5×10-2～1.7×10-2, 0.09×10-2～0.10×10-2, 0.39×10-2～0.56×10-2, respectively; Chuliang 1.4×10-2～1.8×10-2, 0.08×10-2～0.11×10-2, 0.38×10-2～0.62×10-2, respectively.
