| 中文摘要: |
| 以30年生枳砧清家脐橙和纽荷尔脐橙为材料，分析果实生长发育过程中N、P、K、Ca、Mg、和S 6种大量营养元素含量和累积量变化。结果表明，果实生长发育过程中，纽荷尔和清家果实中N、P、Mg和S含量4月最高，Ca在10月最高，纽荷尔和清家K含量分别在9月和7月最高；纽荷尔果实的N、P、K、Mg和S主要累积时期为7～9月，Ca主要累积时期为9～10月；清家果实的N、P、K、Mg和S主要累积时期为6～8月，Ca主要累积时期为8～10月。清家脐橙果实中大量营养元素的主要累积时期比纽荷尔脐橙早1个月左右。 |
| 英文摘要: |
| The changes of nutrient element contents and accumulation of N, P, K, Ca, Mg and S, in fruits of 30 years old Seike navel orange(Citrus sinensis Osbeck cv Seike) and Newhall navel orange（Citrus sinensis Osbeck cv Newhall）on trifoliate orange(Poncirus trifoliata (L.)Raf.) rootstocks were studied. Results showed that during the fruit development, N, P, Mg and S contents in fruits reached the highest levels in April both for Newhall and Seike navel oranges. The highest K content of Newhall navel orange appeared in Sept., but Seike navel orange appeared in July. The highest Ca contents for the two varieties appeared in Oct. The main accumulation periods of N, P, K, Mg and S in fruits were from July to Sept. for Newhall navel orange, and from June to Aug. for Seike navel orange. The main accumulation period of Ca was from Aug. to Oct. for the two varieties. |
