硅素对水稻的增产作用,在日本、朝鲜及我国南方几省(包括台湾省)早已被田间试验和生产实践所证实,在缺硅的土壤上,施硅肥一般可增产10％左右,在日本和朝鲜硅肥已成为水稻生产中大宗肥料之一。我省硅肥资源丰富,近年来亦有在局部地区稻田施用硅肥试验结果的报道,但大批量的硅肥生产和大面积使用尚未开始。本文就我们1980年以来,对苏南水稻土硅素营养水平及硅肥在青紫泥中对水稻增产效果的研究作综合性的报告,为生产部门开发水稻新肥源提供科学依据。
In Japan, North Korea and several southern provinces in China (including Taiwan Province), silicon production has been confirmed by field experiments and production practices. Silicon fertilizers generally increase yield by about 10% in silicon-deficient soils. In Japan North Korea’s silicon fertilizer has become one of the staple fertilizers in rice production. In our province, silicon fertilizers are rich in resources. In recent years, there have also been reports of the results of applying silicon fertilizers in paddy fields in some areas. However, the large-scale production and large-scale use of silicon fertilizers have not yet started. Since 1980, we have made a comprehensive report on the effects of silicon nutrition on paddy soil and the effect of silicon fertilizer on the yield increase of rice in the southern Jiangsu paddy so as to provide a scientific basis for the development of new paddy fertilizers in the production sector.
