研究认为,土壤有效含硼量低于0.5毫克/千克,作物一般就表现为缺硼;低于0.2毫克/千克时则会严重缺硼。我国现有耕地中约有70%～90%的土壤严重缺硼,对农作物的产品、品质产生着较大影响。常用的硼肥以硼砂为主,但近来市场上假冒硼肥产品较多,包括标识不明、含量不够、偷换养分概念等。因此,关于硼肥产品的选择与正确施用必须引起广大农民朋友的重视。本刊从这期开始,特约请有关专家就油菜、棉花、花生、果树等施用硼肥技术规范,以及几种常用硼肥性能比较、硼肥品种的选择等作一系列介绍,或许会对您有所帮助。
According to the study, the available boron content of soil is less than 0.5 mg / kg, and the crop generally shows boron deficiency. If it is less than 0.2 mg / kg, it will seriously lack boron. About 70% -90% of the existing cultivated land in our country is seriously deficient in boron, which has a great impact on the products and quality of crops. Borax commonly used to borax-based, but recently on the market more counterfeit boron products, including the logo is unknown, the content is not enough, stealing the concept of nutrients. Therefore, the choice of boron fertilizer products and the correct application must arouse the attention of the majority of farmers and friends. This issue from the beginning, special invited experts on rapeseed, cotton, peanuts, fruit trees, such as the application of boron fertilizer specifications, as well as several commonly used boron fertilizer performance comparison, the choice of boron fertilizer varieties for a series of introduction, may you Help
