In 2008, since the start of soil testing and fertilizer application in Taoyuan County, the soil and fertilizer station office and laboratory reached 350m2. The soil and fertilizer station is based on the full integration of its original resources. It has built a high-standard laboratory and transformed its water, electricity, and operation countertops. Since the implementation of the soil testing and fertilization project in 2005, many new agricultural network instruments such as soil testing and formula fertilization meters have been added and updated, and the implementation of the technology should also ensure the quality control.
First, strict sample registration system. When the field sampling is sent to the laboratory, a specific person shall be responsible for the registration of the sample acceptance, and carefully check the label content of the soil testing and fertilizer applicator sample with the field survey form, fill in the sample registration form, and complete the sample label, field survey form, and sample Registration table 3 is consistent with the table, in the amortization, sample collection, sample preparation and analysis process, at any time pay attention to the verification and confirmation of the sample, and prevent the wrong number.
The second is to ensure the quality of sample preparation. In order to ensure sample quality and control the fineness of the sample, manual sample preparation was used. This is also conducive to better control of the sample measurement accuracy with the soil testing and formula application instrument.
The third is to establish a random inspection system within the laboratory. The laboratory has a clear and dedicated person in charge of quality and occasionally checks the results of the analysis.
The fourth is to control the sampling error. Firstly, according to the test items and requirements for soil testing and formulated fertilizer applicators, a detailed sampling plan should be formulated. Appropriate sampling tools, sample containers, and reasonable sampling points should be used to ensure sampling depth and shape according to the principles of randomization, equal volume, mixing, and pollution prevention. The same size, according to the standard collection of a certain soil sample mix, minimize sampling error, promptly sent to the laboratory, according to the provisions of the sample processing and storage.
Over the years, the technical conditions of the laboratory have been greatly improved, and the need for normal and safe laboratory work has been met, ensuring that the laboratory is in a good state of operation. The soil testing and formula application instrument obtained a large amount of technical data in this technology, which laid the foundation for establishing a systematic soil testing and fertilizer application technology system. Obtained a relatively complete sample of the basic conditions of the plot, soil and plant test results, field trials and other basic data, to lay a solid foundation for the implementation of arable land fertility evaluation, the establishment of the main crop fertilization index system.
