本专利介绍的铺膜-打孔机可铺放各种薄膜,尤其适合铺放光解膜。铺膜与打孔同时进行。孔的大小和倾斜度可调节。在玉米地里覆盖薄膜可提高地温,促使玉米种子发芽。但当胚芽与薄膜接触时,需将薄膜收起,或在薄膜上打孔,否则,在薄膜下地温可达50℃,胚芽易被烧坏。而收起薄膜或打孔,不但增加了手工劳动量,而且会损伤胚芽,不利于胚芽的生长。
This patent describes the film - punch can be placed on a variety of films, especially for the deployment of photolytic film. Film and drilling at the same time. Hole size and tilt can be adjusted. Covering the film in the corn field can increase the ground temperature, prompting the germination of corn seeds. However, when the germ is in contact with the membrane, the membrane needs to be stowed or perforated on the membrane. Otherwise, the temperature of the membrane can reach 50 ° C, and the germ is easily burnt out. And put away the film or punch, not only increased the amount of manual labor, but also damage germ, is not conducive to the growth of germ.
