Response of Soil Physical Environment to Fruit-tree Cultivation
To study the response of soil physical environment to fruit-tree cultivation, take the half-hillside area in Anning river region of Liangshan Yi Nationality Autonomous Prefecture, Sichuan province as experimental site, and analyze its soil physical properties after fruit-tree cultivation comparing with those of wasteland without cultivation management. Results showed that soil bulk density at different soil layers of experimental site with fruit-tree cultivation declined except for soil samples at 0-20 cm under olive trees. Compared with wasteland, average soil porosity of experimental site increased 25.2% to 31.7%. And content of soil micro-aggregates increased while that of aggregate decreased. Meanwhile, soil dispersion coefficient of experimental site with fruit-tree cultivation decreased 7.4% to 23.9%, while structure coefficient increased 2.2% to 7.0%. Furthermore, soil moisture content of experimental site was significantly higher than that of wasteland, and it increased as soil depth increased. Average soil moisture content of soil samples collected under loquat trees was the highest, which was 117.3% higher than that of wasteland. It indicated that, after fruit-tree cultivation management, content of soil organic matter improved, structured degree of soil increased and water and fertilizer retention ability of soil enhanced.
