常规覆膜技术由于平铺地膜,降雨时雨水顺着膜面流到膜床两边,很难渗透到膜内,不能充分利用自然降雨。针对这种情况,涿鹿县农机研究所成功地研究出双槽聚雨抗旱覆膜技术,它使膜床两个种植行成为沟槽状,可使自然降于床面上的雨水聚集到苗孔内,顺着种植孔进入膜内渗入土壤,便于作物吸收利用,大大提高了自然降雨利用率。同时,他们还先后研制成功与该项技术配套的聚雨抗旱铺膜机Ⅰ型和Ⅱ型。该机分畜力和机引两种,集沟槽覆膜、深施底肥、膜床打孔(进水孔、播种孔)、播种覆土堵孔等一次完成。并可对聚雨槽距进行调节,以适应不同地区及不同作物的农艺要求。去年,在小面积试验成功的基础上,该研究所在张家口地区及内蒙乌盟 Conventional coating technology due to tile tiling, rainfall, rain along the membrane surface flow to both sides of the membrane bed, it is difficult to penetrate into the membrane, can not take full advantage of natural rainfall. In view of this situation, Zhuolu County Agricultural Machinery Institute successfully developed a double-slot rainwater-resistant film technology, which makes the film bed two planting rows become groove-shaped, can naturally fall on the bed of rainwater gathered to the seedlings Hole, along the planting hole into the membrane infiltration of soil, facilitate the absorption and utilization of crops, greatly improving the utilization of natural rainfall. At the same time, they also successively developed type I and type II rainwater-proof film-forming machines which are successfully matched with the technology. The machine divided into two kinds of animal power and machine, set trench coating, deep base fertilizer, membrane bed drilling (water holes, sowing holes), sowing soil covering holes and other completed. Polygam slot spacing can also be adjusted to meet the agronomic requirements of different regions and different crops. Last year, based on the successful small area test, the institute is located in Zhangjiakou, Inner Mongolia and Inner Mongolia
