【摘要】 根据我们的试验参考文献资料,综述了硅肥改善20多种作物品质新进展.硅肥能够提高水稻出糙率和精米率、烟草内在质量、提高甘蔗和葡萄等含糖量。硅肥可以增加苹果、葡萄、番茄硬度或抗挤压强度,同时能够增加油桃、草莓、茄子、芹菜维生素C。硅肥还可提高油桃、大葱蛋白质含量,对草莓、茄子、大棚芹菜叶柄可溶性固形物增加,大棚芹菜硝酸盐含量下降。文中从提供硅素营养、增加中微量元素供给、协调养分供应、提高抗逆性等方面深入分析了硅肥提高改善农作物品质的机理。最后展望了硅肥提高改善农作物品质研究趋势和硅肥应用前景。更多还原

【Abstract】 The article summarized the effects of silicon fertilizer on quality improvement in 20 crop species according to filed trials and reference.After application of silicon fertilizers,the rate of brown rice and polished rice were improved,the inner quality of tobacco was enhanced,the sugar contents of sugarcane and grape were increased. Silicon fertilizer could enhance hardness and pressure-resistance of apple,grape and tomato,and increase Vitamin C of nectarine,strawberry,eggplant and celery.Silicon fertilizer could increase protein content of nectarine and scallion,soluble solids of strawberry,eggplant and greenhouse celery,and reduce nitrate content of greenhouse celery. The possible mechanisms of improvement of silicon for crops were analyzed intensively in the present paper in the following aspects:silicon provision,adding micro-nutrient supply, coordination of nutrition supply and enhancement of resistance to stressful conditions. Finally,the research perspectives were also discussed on trends of silicon fertilizer for improving crop quality and silicon fertilizer application.更多还原
