地膜覆盖技术能显著促进作物生长,提高产量,但有个很大的缺点:作物整个生长期内不能有效补充水分养分,特别是膨果期或灌浆期,易造成作物的脱水脱肥,地膜覆盖的优势得不到充分发挥。简易微灌法,是将输水管预先埋置地膜下,实现随时供水供肥。方法如下:1.材料塑料管,要求有一定硬度,如夏天热水袋的导水管即可,长度略大于畦长。根据作物种植密度,用电烙铁沿管烫小圆孔,左右相间隔,用人造棉球塞实,以防被土堵住,而水可以渗出。
Film mulching technology can significantly promote crop growth and increase yield. However, there is a big disadvantage that crop can not effectively replenish water and nutrients during the whole growth period, especially during the expansion and filling stages, which can easily lead to crop dewatered and plastic film mulching The advantages can not be fully realized. Simple micro-irrigation method is to pre-buried pipe under the submerged membrane to achieve water supply at any time. The method is as follows: 1. Material plastic pipe, require a certain hardness, such as the water pipe can be hot water bag in summer, the length is slightly longer than 畦 long. According to crop planting density, electric iron along the pipe ironing small round hole, left and right phase interval, with artificial cotton balls stuffed to prevent being blocked by soil, and water can seep.
