硅酸盐菌剂对水稻生物学性状及养分累积的影响
Effects of Silicate Bacterium on Biological Character and Nutrients Accumulation of Rice
摘要
Abstract
A pot experiment was conducted to study the effect of silicate bacterium on biological character and nutrients accumulation of rice. The results showed that, compared with the control, the root dry weight increased by 30.3%, the spike dry weight increased by 10.1%. Silicate bacterium application significantly increased the nutrient content in the main growth stages of rice, compared with the control, the total nitrogen content increased by 7.4%~31.7%, the total phosphorus increased by 7.4%~14.3%, the total potassium in-creased by 3.7%~18.3%, the total silicon increased by 5.9%~7.9%. The available silicon content in soil can be maintained at a high level with silicate bacterium application, the content of available silicon in soil increased by 2.8% after the rice harvest. Therefore, silicate bacterium can promote the growth of rice, increase the main nutrient accumulation of rice and the content of available silicon in soil. Silicate bacterium has a good application prospect.关键词
