塑膜滴灌,就是将水贮存于塑料薄膜袋内,水通过塑料细管,以点滴的方式,经常地、缓慢地滴入果树根部,使根区的土壤始终保持适宜的水分。塑料膜滴灌系统的具体做法如下: 一、挖塑膜床。在距树干0.6m处,纵向挖塑膜床,长0.8m,宽0.3m。二、做塑膜袋。塑膜袋可大可小,根据畜力运水情况确定。再选取一根40cm长,内径3mm的塑料 Plastic film drip irrigation, that is, the water stored in plastic film bag, water through the plastic thin tube to the drip, often, slowly drip into the roots of the roots, so that the root of the soil has always been to maintain appropriate moisture. Plastic film drip irrigation system specific practices are as follows: First, dig plastic bed. At a distance of 0.6m from the trunk, the longitudinal digging membrane bed is 0.8m long and 0.3m wide. Second, do plastic bags. Plastic bags can be large and small, according to animal feed water conditions identified. Then select a 40cm long, 3mm diameter plastic
