【摘要】 本文以3年生主干形整枝的“新川中岛”桃为试材,探讨了叶面施肥对叶片叶绿素含量,含氮量及果实品质的影响。结果表明:叶面喷施含氮120mg·L-1和240mg·L-1的复合液肥可以延缓叶片衰老过程中叶绿素含量的下降,果实含酸量下降,固酸比提高,品质有所改善。更多还原

【Abstract】 Effect of foliar fertilization on leaf chlorophyll, total nitrogenous concentration and quality of matured fruit were investigated with 3 year old trained central leader type Kawanakashima peach trees.The result showed that decrease of leaf chlorophyll was delayed during leaf senescence, the concentration of titratable acidity was declined, and TSS/acidity was increased by foliar fertilization with complete liquid fertilizer containing 120 mg·L-1or 240 mg·L-1 nitrogenous. So the fruit quality was improved.更多还原
