摘要
研究了不同核桃园片不同物候期"绿岭"核桃叶片矿质元素含量与果实产量的关系。结果表明,展叶后期含N量与其呈显著正相关;盛花期、果实成熟期和树体恢复期含P量与其均呈显著正相关,硬核期呈显著负相关;幼果速长期含Ca量与其呈极显著负相关,盛花期、成熟期均呈显著负相关;幼果速长期和硬核期含Mn量与其呈极显著负相关,展叶后期呈显著正相关。
The relationships between leaf mineral elements and yields of different walnut or- chards of Lvling walnut at different phenological phase were studied. The results showed that there existed significant positive correlation between N content and fruit yield in the end of frondesce and also between P content and fruit yields in the period of full blossom, fruit ripeness, tree recovery. However, significant negative correlation between P content and fruit yield was found in shell hardening period, while very significant negative correlation be- tween Ca content and fruit yield was found in young fruits fast growth period. Besides, there existed significant negative correlation between Ca content and fruit yield in full blossom pe- riod and fruit ripeness period and very significant negative correlation between Mn content and fruit yield in young fruits fast growth period and shell hardening period, with significant positive correlation between Mn content and fruit yield in the end of frondesce.
