全膜双垄沟播起垄施肥铺膜机的研制

针对全膜双垄沟播种植的农艺要求,研制了一种起垄施肥铺膜机,可完成起垄、施肥、喷药、铺膜和覆土压膜联合作业。用旋耕方式整地起垄,覆土装置实现地膜纵向两边均匀覆土和地膜横向间隔覆土。采用旋耕前喷药和铺膜前施肥的作业方式,保证药效和肥效最大限度地发挥作用。试验表明,垄面光滑,无明显缺陷且覆土后的地膜无机械破膜现象。膜横向覆土距离的平均值为102 cm,纵向覆土厚度和宽度的平均值为5.1 cm和11.4 cm,大垄的垄宽和垄高的平均值分别为69.3 cm和14.9 cm,小垄的垄宽和垄高的平均值为40.5 cm和15.2 cm,满足全膜双垄沟播种植农艺要求。覆土的厚度、宽度的变异系数分别为4.83%和7.52%,大垄宽度、高度的变异系数为1.22%和2.14%,小垄宽度、高度的变异系数为2.26%和1.58%,符合设计要求。

Whole plastic-film double furrow sowing cultivation of the design and manufacture of ridge fertilization filming machine

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.
