Abstract
Potatoes are often harmed by weeds in the planting process, and thus the yield of the potatoes is reduced. Currently, the weeds in fields of the potatoes are mainly removed by covering the fields with black mulching films or spraying pre-emergence herbicides after seeding; the weeds can be removed by covering the fields with the black mulching films, however, the black mulching films are non-transparent, heat produced by light irradiation is completely isolated above the mulching films, the ground temperature hardly rises, and relatively large influence on germination and emergence of the potatoes is caused; emergence barriers to the potatoes are caused easily if the pre-emergence herbicides are sprayed after seeding of the potatoes. According to a novel method for removing the weeds in the planting fields of the potatoes, the fields are covered with white and transparent mulching films after seeding of the potatoes, the field temperature can be increased by 2-4 DEG C, the potatoes can emerge 5-7 days earlier, the emergence rate is increased by 10%-15%, after emergence of the potatoes, surfaces of the white and transparent mulching films are coated with a black pigment, the mulching films coated with the black pigment are almost non-transparent, and weeds in the films are prevented from being exposed to the sunlight and die due to the fact that the weeds cannot perform normal photosynthesis due to lack of light irradiation.
