- 摘要:
- 为了提高钾高效番茄品种的筛选效率，以4种番茄品种为试材，采用土培盆栽方式，研究了不同取样时期对番茄苗期钾利用指数的影响，并确定了筛选番茄苗期钾高效基因型的最适指标与最佳时期。结果表明：番茄苗期钾高效基因型的最适筛选指标为根系活力，最佳时期为钾处理后第21天。
- Abstract:
- In order to improve the efficiency of potassium and efficient screening of tomato varieties，with 4 varieties of tomatoes as materials，by potted soil culture methods，the effect of different sampling periods of tomato seedling potassium utilization index and determine the optimal screening index and the best period of potassium efficient genotypes of tomato seedlings were studied.The results showed that the tomato seedling potassium efficient genotypes of optimal selection was the root activity，21 days was the best period for potassium treatment.
