Embodiment 1
[0060] A method for measuring and analyzing the pore structure of saline-alkali soil. The soil sampling container is a PVC hard pipe with an inner diameter of 11 cm, a length of 40 cm, and a pipe wall thickness of 0.5 cm. One end is ground into a knife-edge. The test site is located in Dafeng Nature Reserve (32°59’N, 120°49’E) in Yancheng, Jiangsu Province. The soil tested was natural saline-alkali soil for Jerusalem artichoke planting - no human disturbance (no fertilization, no irrigation) except grass mowing before Jerusalem artichoke seeding. The soil was plowed using conventional mold boards. Jerusalem artichoke has been grown on natural saline-alkali land for 8 years (row spacing 60cm, plant spacing 40cm). Plant at the end of March every year and harvest at the end of November. Jerusalem artichoke planting areas were classified as high-salt (>4.0 g salt kg- 1 Soil), medium salt (2.0-4.0g salt kg- 1 Soil) and low salt (1.0-2.0g salt kg- 1 earth).
