Abstract:

By studying on the effect of spontaneously puncture of plastic-film mulching in the condition of the crops under the soil, defining different kinds of crops spontaneously puncture of plastic-film ability and its influencing factors. For the development of the farmland mulching plastic-film concise turn technology provides the basis. Filed experimental in combining with statistical analysis was adopted. Clear the eight kinds of crops spontaneously puncture of plastic-film ability, including wheat, corn spontaneously puncture of plastic-film ability was the best, the treatment of relative germination rate could reach more than 98%. Pumpkin spontaneously puncture of plastic-film ability was the weakest. The effect of spontaneously puncture of plastic-film mulching was susceptible to the cover material. The condition of black plastic-film mulching relative germination rate was significantly higher than the white plastic, using black mulch was more advantageous to crop spontaneously puncture of plastic-film. In the membrane of overlying soil could effectively enhance the mulch and the suppression of weeds effect, two films on weed inhibitory effect was similar. Crop spontaneously puncture of plastic-film could effectively reduce the plastic sheeting's man-caused and natural damage, improving the effect of plastic-film mulching, it was to explore the effective application of new direction plantation.
