摘要
为充分发挥硅钙肥在水稻上的应用效果,进行了硅钙肥作基肥450～750kg/hm2的大面积示范试验。结果表明,硅钙肥可使水稻有效分蘖率提高23.3%,平均单株成穗数增加0.7穗,增产4.3%～18.1%,对提高水稻的抗病能力也有一定作用。
In order to make the adequate effect of Si-Ca fertilizer on rice,made the large area demonstration experiment by applying Si-Ca fertilizer as base fertilizer by450～750kg /667m 2 .The result showed,Si-Ca fertilizer made percentage of effective tiller increase by23.3%,percentage of fruitful spike by0.7spikes,increased production by4.3%～18.1%,had a certain effect on improving disease resistant capability of rice.
