[ Focus on Chemical Machinery and Equipment Network ] The "14th Five-Year Plan" and the 2035 long-term goal outline clearly stated that the black soil protection project should be implemented to strengthen the black soil protection and restoration of the northeast.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment"Pinch the black soil to make oily flowers, and insert a pair of chopsticks to sprout.
" Since the black soil of Northeast China was cultivated, fertility has been synonymous with it.
The vast Northeast Plain has therefore become my country's main commercial grain base.
The Heilongjiang Reclamation Area is located in one of the world's three largest black soil belts, with more than 44 million mu of arable land and a comprehensive grain production capacity of over 40 billion catties.
Over the years, the grain output of the three northeastern provinces has been steadily increasing, which has provided an important guarantee for my country's food security.

Over the years, the grain output of the three northeastern provinces has been steadily increasing, which has provided an important guarantee for my country's food security.
However, behind "the Northeast is ripe for the world," the black land is facing serious degradation problems.
Factors such as high-intensity utilization and unreasonable farming methods have caused soil erosion, soil organic matter content decline, and ecological degradation of the soil in the Northeast Plain.
The fertile black soil is becoming "thin", "lean", and "hard".

Cultivated land is the lifeblood of food production.
Therefore, we insist on both rational utilization and strict protection of cultivated land, with equal emphasis on economic and ecological benefits, and effectively protect the black land, the'giant panda in cultivated land', and keep the quantity and quality of cultivated land in the'double red line' Continuously consolidate the foundation to ensure national food security.

The protection of cultivated land quality requires monitoring data support.
Soil environmental monitoring focuses on soil pollutants, and the main monitoring objects are inorganic pollutants such as heavy metals and salts, pesticides and veterinary drug residues, and chemical fertilizers.
The monitoring of cultivated land quality is very different, focusing on physical and chemical properties such as soil structure, compactness, bulk density, chemical properties (including organic matter, pH, total nitrogen, etc.
).

In addition, it also includes the agricultural production profile of the monitoring point, such as the amount of fertilizer, the types of crops and the yield.
The objects of cultivated land quality monitoring are different from soil environmental monitoring, and the required equipment and standard methods are also different.
Conventional detector comprises a cation exchange capacity detector soil, soil pH automatic analyzer, automatic Kjeldahl instrument.

Remote sensing and GIS spatial analysis techniques can also be used to develop the intensity and type of soil erosion on the black soil cultivated land in the Songnen Plain through vector superposition of terrain, vegetation, soil, meteorology and other factors that drive soil erosion.
Define, find out the type, area and distribution characteristics of soil erosion on black soil cultivated land, propose corresponding prevention and control strategies, and provide scientific basis for black soil protection and ecological agriculture construction.

The "14th Five-Year Plan" clearly strengthens the protection of black soil, and monitoring equipment is also helping.
