总结了在河北省南部黄河故道较贫瘠的砂地上,以田间试验和15N微区试验相结合方法,研究了硼对花生吸收硼和氮的影响,结果表明:1.施硼能促进花生对硼的吸收;2.施硼也能促进花生对氮的吸收,提高了氮肥利用率;3.过量硼会抑制花生的生长。
This paper summarizes the effects of boron on boron and nitrogen uptake by peanuts in the relatively poor sand in the old course of the Yellow River in southern Hebei Province by field and 15N microdialysis experiments. The results show that: 1. Application of boron can promote the absorption of boron in peanuts; 2. Boron application can also promote the absorption of nitrogen by peanut and improve the utilization rate of nitrogen fertilizer.3. Excess boron inhibits peanut growth.
