Subsoiling and land preparation for agricultural machinery is an important agricultural technology, which can bring many benefits to agricultural production. First of all, subsoiling can improve the permeability of the soil, which is conducive to the growth and development of plant roots. Secondly, subsoiling can break the bottom layer of the plough, increase the depth of the tillage layer, improve the water storage capacity and nutrient content of the soil, which is conducive to the absorption of nutrients and water by crops, and improve the yield and quality of crops. In addition, subsoiling can also reduce the evaporation and loss of soil moisture, reduce the occurrence of soil salinization, desertification and other problems, and help protect the soil environment.
In order to give full play to the benefits of subsoiling and land preparation of agricultural machinery, it is necessary to take correct operation methods and precautions. First of all, the timing of subsoiling and land preparation should be selected in the period when the soil moisture is suitable, generally in spring or autumn.
Secondly, the depth of subsoiling and land preparation should be determined according to the soil texture and crop type, which is generally required to be more than 25 cm. In addition, it is necessary to keep the field surface flat during subsoiling and land preparation to avoid high-lying unevenness. After subsoiling and land preparation, soil compaction and suppression should be carried out in time to maintain the moisture and compactness of the soil.
In short, agricultural machinery subsoiling is an important agricultural technology, which can improve soil quality, promote crop growth, improve crop yield and quality, and protect the soil environment. In order to give full play to the benefits of subsoiling and land preparation, it is necessary to take the correct operation methods and precautions. It is believed that in the future agricultural production, subsoiling and land preparation technology will be more widely used and promoted.
