00 t/ha was 2, 6,7,and 10 years,respectively; (3)Liming significantly increased seed yield of rapeseed by 19.
结果表明:(1)施用石灰使土壤pH升高和交换性铝含量下降,其降酸作用与石灰施用量呈正相关。
It is very necessary to decide the lime requirement through chemical method.
在四川盆地8处采样点采集的土壤分别用这3种方法确定石灰需要量,将土壤实际培养所得的石灰用量作为标准方法,再将上述3种方法的测定结果分别与标准法进行线形相关分析,得到与标准曲线之间的线形方程,结果发现3种方法与标准方法之间均成线性相关,在确定石灰需求量上都具有一定的准确度,但相对而言,文章提出的滴定法更准确,更适合确定四川土壤的石灰施用量。
Several other materials can be used for liming purposes, such as, baked or burned oyster shells, marl, basic slag, wood ashes, and cement industry by-products.
