| Abstract: |
| This study used Silihong peanut plants under the forest fruit intercropping mode in the central and western regions of Xinjiang as the research materials. Based on the field investigation of peanuts, it examined the moisture content, seedling stem node, fruit stem node and fruit stem stretching force, the anti-extrusion pressure of peanut pods, as well as the resistance of peanut pods to extrusion of the wind speed range of stems and leaves under different moisture levels. The optimum harvest time was preliminarily determined to be 5~7 days. During this time, the moisture content of peanut plant, fruit stalk and peanut pod were from 34.5% to 24.0%, from 22.0% to 16.0%, from 14.0% to 9.0% respectively. The tensile force of fruit stalk, seedling stalk node and fruit stalk node were 14.95~15.10, 12.50~12.90 N and 8.45~8.60 N respectively. The extrusion force of peanut pod side, pod front and pod end were from 45.0 N to 41.0 N, from 86.5 N to 70.3 N and from 42.0 N to 36.1 N respectively. The wind suspended velocities of peanut pod, stem and peanut leaf were 5.82~6.97, 2.43~2.77 m·s-1 and 1.97~2.44 m·s-1 respectively. The study provides a parameter basis for design and development of subsequent peanut harvesting machinery. |
