试验证明，水培筛选杂交稻和粳稻耐低钾基因型是可行的，筛选的适宜时期分别为八叶期和五叶期，适宜Ｋ＋浓度分别为３ｍｇ／Ｌ和１０ｍｇ／Ｌ；耐低钾基因型和不耐低钾基因型的差异主要在于前者吸收土壤非交换性钾能力强和钾素利用效率高
Experiments show that it is feasible to screen hybrid rice and Japonica rice with low potassium genotype by hydroponics, the suitable period of screening is eight-leaf stage and five-leaf stage respectively, and the suitable K + concentration is 3mg / L and 10mg / L respectively. The main differences between the genotypes and the impatience of low-potassium genotypes were that the former had high ability to absorb non-exchangeable potassium in soil and high potassium utilization efficiency
