Plants need nutrients from the soil and are an important material basis for maintaining the elements that plants need to grow and live, but they also cause environmental pollution. According to the test of the soil nutrient fastness tester, when one or more nutrient contents are low, plant production and quality can be suppressed, and when the content is too high, environmental pollution can be caused. Changes in space and time and rich results reflect the changing characteristics of soil quality.
At present, the researches on the relationship between farmland soil nutrients are mostly a single period, failing to reflect its dynamic changes. The soil nutrient quickness tester took Liaocheng in the western part of Shandong Province as the research area. Through the second soil survey data and sampling analysis, the changes in the relationship between plough layer soil nutrients were studied to provide reasonable utilization of soil resources and ecological environment construction. in accordance with.
The reason for the change of fertility through the soil nutrient fastness meter is limited to manpower and land use. At present, a large amount of compost application is not realistic, and it is necessary to consider the popularization of farmer's farmland conservation knowledge, and how many livestock and poultry farm manures are sterilized. , Applying to farmland, carrying out technical research on the rapid decay of returned straw, improving the efficiency of soil testing and fertilizer application from the aspect of system and mechanism.
Due to the changes in rural social and economic conditions and the increase of farmland input, the soil nutrient content in the study area has been greatly increased, its spatial differences have weakened and the homogenization has increased; the lack of scientific and technological knowledge of farmers and the use of chemical fertilizers are not always reasonable. Therefore, the correlation between soil nutrient content measured by soil nutrient fastness meter was weakened and the coordination was reduced. Individual nutrients with low or high levels of content not only affect the yield and quality of agricultural products, but also contribute to the pollution of the agricultural environment to some extent.
