我这里要向大家介绍一位微生物肥料专家,他就是党的十五大代表、河北省科学院微生物研究所所长刘荣昌。 众所周知,植物在土壤中赖以生存的基本营养是氮、磷、钾,而其中钾对作物品质优劣起着特殊作用,因而被人们称为植物的“质量元素”。我国大地土壤中,虽有充足的钾含量,但这些钾元素却大量存在于矿物质中,不易被植物吸收,形成了土壤中既富钾又缺钾的现象。这就需要人工施用化学
Here I would like to introduce to you a microbial fertilizer experts, he is the party’s 15 representatives, Institute of Microbiology, Hebei Academy of Sciences, Liu Rongchang. It is well-known that the basic nutrition that plants depend on in the soil is nitrogen, phosphorus and potassium. Among them, potassium plays a special role in the quality of crops and is therefore called the “quality element” of plants. Although there is sufficient potassium content in the soil of our country, these potassium elements are abundant in the minerals and are not easily absorbed by the plants, forming a phenomenon that the soil is rich in potassium and potassium deficiency. This requires manual application of chemistry
