      abstract = {After five years of study, it was found that compared with  the conventional cultivation techniques, the average yield  per plant of 3-5-year-old Jinhong apple trees cultivated  under the ridge covering mode was increased by 2.12 times,  the stem diameter was increased by 20%, the branch number  was increased by 73.5%, and the underground root number was  increased by 38.3%. Under the ridge covering mode, the main  distribution area of the underground roots of Jinhong apple  trees was moved down to 15-55 cm, the temperature of soil  20 cm beneath the surface of the ridges increased by  1.3-1.5℃, the temperature of soil 40 cm beneath the surface  of the ridges rose by 0.9-1.0℃, and the water content of  soil 20-40 cm from the ground was maintained around 5%.  Under the ridge covering mode, the Jinhong apple trees grew  robustly, began to fruit 3 years later and yielded highly 5  years later. In addition, the ridge covering model also has  illumination-enhancing, pest-controlling and tillage-free  characteristics. },
