由中国农业科学院土肥所设计研制的新型TFC—2型数字式土肥养分浓度速测计,目前已开始投放市场。我国广大农村,由于种田施肥盲目性大,过多施用化肥,不但造成浪费,而且还会使土壤板结,土质下降。为指导农民合理施肥,农科院土肥所在原来TFC-1型速测计的基础上,新研制出2型速测计,并于去年申请获得国家专利。
The new type TFC-2 digital soil nutrient concentration speed measuring instrument designed and developed by the Institute of Soil Science and Veterinary Medicine of China Academy of Agricultural Sciences has now started to be put on the market. In the vast rural areas of our country, due to the blindness of farming and fertilization, the excessive use of chemical fertilizers not only results in waste, but also causes soil compaction and soil quality to drop. In order to guide farmers to rational fertilization, the original TFC-1 type speedometer located in the Academy of Agricultural Sciences is based on the newly developed type 2 speed meter, and applied for the national patent last year.
