１９９４～１９９６年，在硅钙肥开发应用研究中，开展了果树应用硅钙复混肥效应研究。研究结果表明，在氮磷钾配比为１３：６：６的条件下，加硅钙肥２５％，可使产量增加６％～２２％，加硅钙肥５４％，可使产量增加１３％～２７％。考虑各种营养元素的均衡吸收，复混肥中硅钙肥的掺入量可占２５％或适当再多点。复混肥中钾量减半基本不增产，无钾则减产，说明钾肥用量应接近氮量的一半，不可任意削减。
From 1994 to 1996, the research on the application of calcium silicate fertilizer was carried out in the research on the application of calcium-silicon compound fertilizer to fruit trees. The results showed that 25% calcium silicate fertilizer could increase the yield by 6% ~ 22% with the ratio of NPK to 13: 6: 6, and add 54% calcium silicate fertilizer to increase the yield by 13% ~ 27%. Taking into account the balanced absorption of various nutrients, calcium silicate fertilizer compound fertilizer can account for 25% or more appropriate. Half of the amount of compound fertilizer in halved basically increase production of potassium, potassium production is reduced, indicating that the amount of potash should be close to half of nitrogen, not arbitrarily cut.
