本文报道了在亚热带昆士兰地区季节大造品种产量形成与叶片含N量之间的关系,叶片含N量受不同施N水平所控制,研究的主要目的是观察在不同的气候条件下开花、发梢和叶片含N量之间的关系及确定叶片含N水平最稳定的树体生长时期。
This paper reports the relationship between the yield formation and leaf N content in the major tree species during the subtropical Queensland season. The N content of the leaves is controlled by different N levels. The main purpose of the study is to observe the flowering and the shoot development under different climatic conditions And leaf N content and to determine the leaf N-containing levels of the most stable tree growth period.
