Full-automatic nitrogen determination instrument is a modern experimental instrument developed and designed by TOP Yunong. It is mainly used to measure the nitrogen content in items. We know that nitrogen is one of the important elements in the biological world. It is not only found in soil, food, organisms, and minerals, but it has a large content in the air. As people's understanding of nitrogen deepens, it has been discovered that supplementing plants with appropriate nitrogen can increase crop yields. Therefore, in modern agricultural planting management, people often use nitrogen fertilizer to increase production. However, soil problems caused by improper use are frequent. In order to improve the soil problems and solve the problem of nitrogen content in the soil, people have used a full-automatic nitrogen determination instrument to conduct a large number of experiments and found that it is possible to grow soybeans. Ways to improve soil fertility.
The automatic nitrogen determination device is a simple and convenient nitrogen measurement device, which can accurately determine the nitrogen content in items. Therefore, the instrument has a wide range of applications in many fields. For example, by using a fully automatic nitrogen determination instrument to detect changes in nitrogen content in various parts of soybeans and nitrogen in planting soil, it has been found that rhizobium in the roots of soybeans adsorb nitrogen in the air and convert it into ammonium nitrogen that can be absorbed by crops. Nitrogen content in soil. At the same time, soybean straw is rich in organic matter, which can increase the content of organic matter in the soil. In addition, there is sufficient moisture in soybean stalks in autumn, and the external environment temperature is suitable, and the decay rate is fast.
Autumn soybean is a season crop that is planted in the autumn free space after harvesting of large spring crops such as rice and corn and before sowing of small spring crops. No-till cultivation of autumn soybeans refers to a cultivation method that directly ditches live or nesting on demand without ploughing the land after the harvest of rice, corn, etc., this cultivation mode is a kind of protective cultivation combined with land Technology is an important measure to adjust the agricultural structure and increase farmers' income. It is also an important way to reform the cultivation system, fertilize the soil, promote sustainable agricultural development and a virtuous cycle of agricultural ecology.
Therefore, people will improve the soil fertility by planting soybeans and using soybeans to return to the field. This will not only achieve the recycling of organic matter in the soil, but also effectively increase the content of nitrogen and other trace elements in the soil. Improving soil quality can play a certain promoting role.
