常量元素与微量元素以及各元素间的相互作用对农业生产中合理施用化肥有重要作用.陈保生和崔澂(1966)证明缺锌植物增施氮肥可使缺锌症状提早出现,且更严重.祈明和章土炎(1982)对水稻氮素代谢的研究指出,缩苗植株内全氮量增加.我们曾对磷、锌关系进行研究,本文将阐明氮、锌连应.黄土地区土壤大多氮素含量较低,有些土壤有效锌亦缺,弄清作物对氮、锌配合施用效应以及对土壤、植物营养和氮肥利用率的影响,可为农业生产中合理施用氮肥和锌肥提供科学依据.
The interaction between the major and trace elements and the various elements play an important role in the rational use of chemical fertilizers in agricultural production. Chen Baosheng and Cui Ying (1966) demonstrated that zinc deficiency can be earlier and more serious in the zinc-deficient plants. Zhiming and Zhang Tuyan (1982) studied the nitrogen metabolism in rice and found that the total nitrogen content in the plantlets was increased.We have studied the relationship between phosphorus and zinc, and this article will clarify the relationship between nitrogen and zinc in the loess soil Low content of some soils and lack of available zinc in some soil so as to find out the effect of crops on the application of nitrogen and zinc and their effects on the utilization of soil, plant nutrition and nitrogen fertilizer, which can provide a scientific basis for rational use of nitrogen and zinc fertilizers in agricultural production.
