摘要
1998～1999年进行了甜菜酸性土壤改良试验 ,结果表明 ,施用熟石灰可有效地中和土壤酸度 ,补充甜菜所需要的钙 ,在15cm耕层内增施熟石灰31.3g/m2,pH值可提高0.1。土壤 pH值越接近中性越有利于甜菜生长 ,土壤越酸 ,施熟石灰增产效果越显著。
Sugarbeet improved tests have carried out in 1998～1999 on acid ground,the results have showed that acidity could be neutralization with slaked lime,calcium supplied to sugarbeet growth, supplied slaked lime 31.3 g/m2 in 15cm soil layer, pH get high 0.1, the neutral soil is the best for sugarbeet growth and it can be significant with more slaked lime applied in higher acidity.
