摘要

After five years of study,it was found that compared with the conventional cultivation techniques,the average yield per plant of3-5-year-old Jinhong apple trees cultivated under the ridge covering mode was increased by 2. 12 times,the stem diameter was increased by20%,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.
