| 摘 要： | 硅肥明显降低水稻无效分蘖和增加穗粒数，对其他产量构成因素均有不同作用。施硅肥可提高子实Ｎ、Ｋ和秸秆Ｐ、Ｓｉ含量，还明显提高子实Ｎ、Ｐ、Ｋ和秸秆Ｐ、Ｓｉ的吸收量。在冲积型和白浆型水稻土上，每公顷施硅肥７５０～９００ｋｇ，增产效果显著或极显著，达８．４％～１８．６％，产投比为１：３．３８～９．２３，获纯收入４２９～１４８２元。

A Study of Silicon Fertilizer on Nutrient Uptake and Yield in Rice |
| |
| Abstract: | Silicon fertilizer Significantly decreased ineffective tillers, increased number of grains per panicle and affected on other Constitute factors of yield. Applied Si increased N, K Content in the grain and P, Si Content in the straw, and Significantly in creased N, P, K uptake in the grain and P, Si uptake in the straw. Applied Si fertilizer 750～900kg/hm2 Significant increased yield by 8. 4%～18. 6%. The ratio of input to output was 1: 3. 38～9. 23, the net income by Si upplication was 429～1482 yuan/hm2 in alluviation type paddy soil and baijang type paddy soil. |
