据国外报道,蔗田施水泥(主要成分是硅酸钙)能显著提高甘蔗产量,而且在含硅量低的土壤,新植蔗施水泥,可使种植周期达6年的甘蔗年年增产。为了探讨甘蔗施用水泥的效果及其有效的施用技术,我们从1979年开始进行了试验。1979年共设置9个试验点,面积共55.7亩; According to foreign reports, sugar cane Tian Shi cement (the main component is calcium silicate) can significantly improve the yield of sugarcane, but also in the low silicon content of soil, the new plant cane cement, planting period up to 6 years of sugarcane annual increase. In order to investigate the effect of sugarcane application of cement and its effective application techniques, we have carried out experiments since 1979. In 1979 a total of nine test points, with a total area of ​​55.7 acres;
