Aiming at agricultural demands of whole plastic-film double furrow sowing cultivation,developed a kind of ridging fertilization film machine,may complete the ridging、fertilization、spraying、mulching and earth-pressure plastic-film combination type processes.Ridge with the rotary way of soil preparation,earthing device to achieve uniformity of film on both sides of the vertical casing and the plastic-film covering soil horizontal interval.The use of rotary before the spraying and mulching before fertilization ways,to ensure maximum efficacy of fertilizer and Pesticides.The experiment indicated that the ridge surface is smooth,and not obvious flaw fills under the level not to have the machinery broken membrane phenomenon.the average distance of lateral soil covering is 102 cm, the average value of longitudinal covering soil thickness and width is 5.1 cm and 11.4 cm,the average value of width and height of the big ridge is 69.3 cm and 14.9 cm,the average value of width and height of the small ridge is 40.5 cm and 15.2 cm meet the entire membrane double ridge and furrow planting agronomic requirements,the variation coefficient of covering soil thickness and width is 4.83% and 7.52%,the variation coefficient of the big ridge width and height is 1.22% and 2.14%,the variation coefficient of small ridge width and height is 2.26% and 1.58%,meets the design requirements. |
