水库化肥养鱼的增产效益,水平不一,关键是必需掌握施用化肥的技术要略。本文从五个方面作简要论述。一、化肥的施用量水库施化肥旨在增加浮游植物的营养元素,提高初级生产力。陆生植物的营养元素主要是氮、磷、钾,在水环境中除了某些含盐量和碱度极低的软水外,一般不会缺钾。钾是陆生植物桔杆的主要元素,浮游植物不需任何支持组织,水库施化肥与农业最大不
The yield and benefits of reservoirs and fertilizers for fish culture are different at different levels. The key is to master the technical essentials of applying fertilizers. This article briefly discusses from five aspects. First, the amount of chemical fertilizer Reservoir fertilizer is designed to increase the nutrient elements of phytoplankton and improve primary productivity. Terrestrial plant nutrients are mainly nitrogen, phosphorus and potassium, in addition to some water in the environment with very low salinity and alkalinity of soft water, the general will not lack of potassium. Potassium is the main element of terrestrial plant straw, phytoplankton does not need any supporting organization, the largest chemical fertilizer reservoir and agriculture
