摘要
氮元素对植物生长起着非常重要的作用,它是植物体内氨基酸的组成部分、是构成蛋白质的成分,也是植物进行光合作用起决定作用的叶绿素的组成部分。通过对核桃楸1年生苗木的氮肥营养研究,探讨氮肥的合理施肥技术。试验结果表明,30g/m是核桃楸的最优氮施肥量,其苗高、地径、主根长、侧根数最优,为核桃楸育苗提供依据。
Nitrogen plays a very important role in plant growth, it is a component of amino acid, protein, it is also part of chlorophyll that play a decisive role in the plant photosynthesis. We discussed the reasonable technology of nitrogen fertilizer through the research of nitrogen nutrition of annual seedlings. The results showed that: the seedling height, ground diameter, root length, number of lateral roots were optimal when the rate of nitrogen fertilizer application was 30g/m. It provided the basis for the cultivation of J. mandshurica seedlings.
