摘要
为探索在富硒土壤环境条件下,稻田增施石灰对促进水稻吸收硒及水稻生长发育和产量的影响,进行了石灰不同用量小区试验研究。结果表明:在土壤含硒条件下,增施石灰能促进水稻吸收硒元素,以增施石灰1125 kg/hm^2的用量为最佳用量。
We conducted a field plot experiment in selenium-rich soil to study the effects of different dosage of lime on selenium absorption,growth and yield of rice. Results showed that lime application in selenium-rich soil could promote rice＇s selenium absorption, and the optimum dosage of lime is 1125 kg/hm2.
