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－Ｃｌ＿２处理。喷施ＫＣｌ和ＣａＣｌ＿２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。
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%fall 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.
