水稻缺硅诊断１．根据植株全硅和土壤有效硅来诊断。据藏惠林报道，我国南方五省稻区缺硅指标为：稻草ＳｉＯ２＜１０％，土壤有效ＳｉＯ２＜９５毫克／克。２．日本每年每亩田所吸收的硅２８％由灌溉水提供，其灌溉水含硅量与水稻含硅量相关系数为ｒ＝０．９７０。如果灌...
Rice lack of silicon diagnosis 1. According to plant silicon and soil available silicon to diagnose. According to Tibet Hui Lim reported, lack of silicon in five rice provinces in southern China indicators: straw SiO2 <10%, soil effective SiO2 <95 mg / g. 2. In Japan, 28% of the silicon absorbed per mu per year is supplied by irrigation water. The correlation coefficient between the silicon content in irrigation water and the silicon content in rice is r = 0.970. If irrigation ...
