摘要
通过土培试验,研究了甘肃省石灰性土壤上不同基因型春小麦的磷效率差异。结果表明,不同基因型春小麦磷效率存在明显差异。武春121和038014均有较高的磷吸收效率和利用效率;甘春20具有较高的磷吸收效率;永良4号在不同磷矿粉及改性磷矿粉处理中的磷吸收效率均最低。
Ddifferences of phosphorus efficiency for different spring wheat genotypes were studied by using a pot cultivation method with calcareous soil. The results showed that there were significant differences among the experimental spring wheat genotypes. Wuchunl21 and 038014 had higher phosphorus uptake efficiency and higher utilization efficiency than the others, while Ganchun20 had higher phosphorus uptake capability. But, Yongliang4 showed lowest phosphorus uptake efficiency.
