| 摘 要： | 淮北砂姜黑土上连续三年的试验结果表明,施用氯化钾肥可提高油菜籽粒产量和含油率,但对油菜籽粒蛋白质含量影响不明显。施用氯化钾肥提高了油菜中期茎叶氯、钾离子浓度及成熟期茎叶和籽粒的钾离子浓度,同时增加了油菜对N、P、K养分的吸收总量。对于中等钾含量水平的土壤,施钾(K2O)80kghm-2难以维持土壤钾素养分平衡,当其用量达到160kghm-2以上时,基本能满足作物高产对钾素的需求,并且土壤速效钾含量水平缓慢提高。

| Abstract: | A 3-year field location experiment was carried out to study the effects of potassium chloride on yield and quality of rape in Huaibei area.The results indicated that applying potassium chloride could increase rape yield and oil content of seed,but no obvious impact on protein content of rape seed.Used potassium chloride had improved Cl and K + contents of the stem and leaf of rape in middle-stage,and K + contents of straw and seed in the period of maturity,and increased the gross absorptions of N,P and K.It... |
