摘要
采用盆栽试验研究了以工业副产品硅钙镁磷钾等为主要成分的酸性土壤调理剂对油菜产量、品质及土壤改良效果的影响。试验结果表明,在油菜生育期内,调理剂可以显著提高酸性土壤的p H值和电导率;与空白(CK)处理相比,仅施用调理剂(T)就可以使油菜产量提高13.0%,调理剂和复合肥配施(T+F)可以使油菜产量提高45.0%;仅用调理剂可以使油菜VC含量提高4.3%,硝酸盐含量提高22.45%,对可溶性糖基本无影响。
A pot experiment was conducted to study the effects of byproduct amendments containing silicon,calcium,magnesium,phosphorus and potassium on yield,quality of oilseed rape and improvement of acidic soil. The results showed that,during the growth period of oilseed rape,the p H value and conductivity of acidic soil could be significantly improved by amendments. Compared with the control（ CK）,the amendments（ T） could significantly increase the yield of oilseed rape by 13. 0%,and the amendments with fertilizer（ T ＋F） could increase the yield of oilseed rape by 45. 0%. The amendments could increase the content of vitamin C by 4. 3%,and the nitrate content by 22. 45%,but had little influence on the soluble sugar content.
