试验结果表明,在施用氮肥的基础上,基施(耙面肥)15kg/hm2硅酸盐菌剂对水稻的增产顺序为:未配施磷钾肥>配施磷肥>配施钾肥>配施磷钾肥。配施磷肥时,硅酸盐菌剂对水稻既有较高的产量,又可获得较好的经济效益。3年大田示范印证了试验结果,并发现硅酸盐菌剂对水稻的增产效果随土壤速效钾含量的提高而降低。
The results showed that on the basis of applying nitrogen fertilizer, the order of increasing yield of 15kg / hm2 silicate bactericide based on basal application (rake face fertilizer) to rice was as follows: phosphorus and potassium fertilizers were not applied> phosphorus fertilizers> potassium fertilizers> phosphorus and potassium fertilizers . With phosphate fertilizer, silicate bacteria have both high yields of rice, but also get better economic benefits. The 3-year field demonstration confirmed the test results and found that the yield increase effect of silicate bacteria on rice decreased with the increase of soil available potassium.
