Research and testing on measure the mulch film surface impurities in cotton fields of Xinjiang
In this paper,for the existing residual mulch film recycling machine recovered by the residual mulch film generally exists in the impurity content is high,the residual mulch film is easy to mix with the straw and soil and the mulch film-impurities separation difficulties,according to the cotton fields in Xinjiang region,to carry out the cotton field mulch film surface impurity determination test.The five-point sampling method was used to determine the mulch film surface impurities in seven areas.The results show that the main component of mulch film surface impurities is soil accounting for about 71.38%,and the proportion of impurities such as fallen cotton,cotton husk,chopped cotton stalk and cotton leaf are about 28.62%.The test results can provide theoretical support for the subsequent mulch film surface impurity removal device.
