| 摘 要： | 喷施尿素加剧４４７锦橙裂果，其裂果率显著高于对照，极显著高于喷施ＫＣｌ，Ｃａ－Ｃｌ２处理。喷施ＫＣｌ和ＣａＣｌ２的裂果率较对照降低３７％和３５％，裂果率与叶片含Ｎ量呈正相关，与含Ｋ量呈负相关，枳砧４４７锦橙的裂果率极显著地高于红桔砧。本试验还研究了不同处理及砧木对果实品质的影响。

| Abstract: | Urea spraying aggravated the fruit cracking in Jingchen 447(Citurs sinensis Os-bek).The cracking percentage showed was significantly higher than that of contrast and ofthe spraying treatments with KCl and CaCl2.The last two treatments represented 37%and35?ll respectively.The results also revealed a positive correlation between the fruitsplitting percentage and the nitrogen content in leaves and a negative correlation betweenthe fruit splitting percentage and potassium content in leaves.The fruit cracking ofJingchen 447 grafted on Poncirus root- stock(Poncirus trifoliata Raf)appeared significant-ly more serious than that grafted on tangerine root- stock(Citrus reliculata ). he experi-ment has also studied the effects of various spraying treatments and root-stocks on fruitquality. |
