The soil moisture content was measured once a week, and the soil was stratified by using an earth-boring driller. Each layer consisted of 10 cm and was divided into 10 layers. The depth was taken to 100 cm and repeated three times. The drying method was used to determine the temperature at 108e for 8 h. After selecting the orientation, the coating treatment will take the soil at the actual depth. The thermometer is installed on the same horizontal line at a distance of 1m from the main line spacing. Divide records early in the morning (8:30), (14:30), and (18:00). A soil moisture temperature measuring instrument can also be used to simplify the measurement process and obtain more accurate results, which is conducive to the smooth progress of the research.
The soil water temperature measurement instrument found that after the black mulch film was covered, soil water content was 80 to 140 cm away from the main trunk, while soil moisture content was significantly reduced at 40 to 60 cm from the main trunk. The soil moisture content of 0~60cm soil layer under different coverage is affected by the environment obviously, the soil moisture content varies greatly, and the soil moisture content of 70~100cm is less affected by the environment. Under different coverage in the dry season, the soil moisture content of 0~1m is always maintained at over 13%, which can meet the needs of fruit tree growth in the drought-prone areas in the east. Sand-covered and black-covered mulch can significantly increase ground temperature, and grass-covering can significantly reduce ground temperature. The rise of ground temperature in sunny days was characterized by film covering> sand cover> CK> grass cover; the cloudy, sand-covered, mulching, CK ground temperature changes were generally linear, and the soil temperature difference at different depths became smaller; the temperature change of soil layers under grass cover was affected by The least environmental impact.
The analysis of soil evaporation by soil moisture analyzers showed that these measures can effectively alleviate the water shortage in the orchards in the dry land in the eastern part of Gansu Province. Different coverage patterns can significantly improve the fruit quality and total sugar content. Soluble solids The content of the material increased slightly; the hardness of the fruit covered with black mulch and grass was significantly reduced.
In the current dry agriculture region of the world, there is a farming technology that can suppress soil moisture evaporation, water storage, heat preservation, and temperature preservation. This is a measure of surface cover. The application of this measure has increased the utilization of water. Improved soil physical properties. With the expansion of the scope of application, the widespread application of dryland agricultural production in northern China has also opened up. Although there are studies on the effect of technology on soil moisture temperature, the results of this study cannot be generalized to other regions because of the influence of climatic and geographical conditions. With the continuous increase of apple planting area in eastern Gansu, the soil moisture temperature analyzer has studied the characteristics of soil water and heat distribution in the land covered by dryland orchards, and mastered its changing rules to explore the consumption of dryland orchards suitable for the region's coverage model and different coverage conditions. Water and stimulation mechanisms provide the theoretical basis.
