Soil testing and formula fertilization has been popularized in large areas in China for nearly 5 years. The soil testing and fertilizer applicator has been used for soil analysis and then given a scientific fertilization plan. This method can maximize the increase in agricultural production and The balance of environmental protection.
Our country has achieved remarkable results after pushing the plant to test soil with 10,000 fertilization techniques. However, there are still some problems that need to be addressed in a timely manner. The main thing is that the current application of this technology in our country is not enough to be extensive and in-depth. The use of soil testing and formula fertilization instruments to measure soil testing and fertilizer application technology is still relatively small, and only about 10% of farmers use this technology.
The traditional fertilization mode and blind fertilization are still common in most regions. The mastery of this technology is still not enough to stay in the experimental demonstration stage. The main reasons for this situation are:
1, weak technical links
Although all the agricultural counties in China have already launched a project to test the soil and fertilize 10,000 fertilizers, the real technical household occupancy rate and the extremely low rate of place-in-place are the main reasons for this. The main reason is that China still lacks a sound agro-tech pusher system and it is difficult to push agricultural technology. Factory service work is done
2, test method is not perfect
The current soil nutrient test method in China is complex, the analysis speed is slow, and the time-effectiveness is poor, which cannot meet the requirement of large-scale soil sample testing. It needs to develop a simple, rapid and accurate test method.
3, the inertia of the traditional fertilization mode
“Inorganic, light organic†This is the main feature of our country's traditional fertilization model. The use of neglected organic fertilizer during fertilization is emphasized. Application of nitrogen-based inorganic fertilizers will inevitably lead to decline in crop yield and quality. Environmental pollution and ecological deterioration 24 Inconsistent measurement, distribution, and supply links The current measurement, distribution, and supply links in soil testing and fertilization are severely degraded. The phenomena of far-reaching match and coordination in the measurement, distribution, and supply of various links have directly led to the measurement and fertilization techniques becoming a blank check.
