Silicon and titanium are a large number of yield-increasing elements required for plant growth
Most plants contain silicon, especially rice and sugarcane, its nutritional effect is considered to be the fourth after N, P and K in recent years. Tests show that the absorption of silica is as high as 150 kg when producing 1,000 kg of rice, exceeding the total absorption of N, P and K by rice. In the ash of rice, wheat, barley, soybean, lentil and fennel, the oxides of seven nutrient elements including N, P and K and Ca, account for over 80% of the ash, among which silicon oxides account for 16 ~ 61.4%.
