水土流失区往往也是贫困区,农民群众在农业生产过程中缺肥,特别是磷、钾。而红壤和水稻土中全钾含量还是比较丰富的,全磷也有一些,但是有效磷钾缺乏,导致严重影响农作物产量的提高。本刊这一期特发表沈钦霖同志等“生物钾肥在水稻上的应用效果”,介绍他们在水稻栽培上施用廉价高效能硅酸盐细菌研制成的菌肥田间试验,取得了显著的增产效益和很大的经济效益,提供参考。希对水土流失区农民增产增收有所助益。

Soil and water loss areas are often poor areas as well, and peasant masses are lacking in their agricultural production, especially phosphorus and potassium. The red soil and paddy soil total potassium content is still relatively abundant, there are some total phosphorus, but the lack of available phosphorus and potassium, leading to a serious impact on crop yield. This issue of special issue of Comrade Shen Qinlin comrades and other “bio-potash application effect on rice,” introduced their rice cultivation in the use of cheap high-performance silicate bacteria developed by bacterial fertilizer field trials, and achieved significant yield-increasing benefits and Great economic benefits, provide a reference. Hope that the farmers in soil and water loss areas increase production and income is helpful.
