一、“秸秆捆”的制作与设计技术要点。埋“秸秆捆”前先将树盆修好,然后将玉米秸或高梁秸截成40厘米长,捆成35厘米粗的捆,备用。在树冠垂直方位按不同方向挖3-4个深45厘米、直径40厘米的坑,将捆好的“秸秆捆”竖埋在坑内,四周埋严土,“秸秆捆”上端低于地表5厘米,顺“秸秆捆”向坑内浇水15公斤,将顶部用塑料布盖严,再覆一层土,防止水分蒸发。二、埋“秸秆捆”法节水灌溉的优点。 1.节约灌溉投资。按50亩山地果园计算完成水利配套工程一般需要投资4—5万元,用此法代替,可省投资4万多元,还省去打井配套,水电费用。与人工挑水浇树相比,减少了用工量。 2. 节省了浇水的需用量。一般每亩果园按40
First, “straw bundle ” production and design of technical points. Bury “straw bundle ” before the first tree bureaus, and then corn stalks or sorghum straw cut into 40 cm long, bundled into 35 cm thick bundle, spare. In the vertical direction of the canopy according to different directions to dig 3-4 deep 45 cm, diameter 40 cm pit, the bundle of the “straw bundle” buried in the pit, surrounded by buried soil, “straw bundle ” On the surface of 5 cm, Shun “straw bales ” 15 kilograms of water into the pit, the top covered with plastic sheeting, and then covered with a layer of soil to prevent evaporation of water. Second, buried “straw bundle ” method of water-saving irrigation advantages. 1. Save on irrigation investment. Calculated according to 50 acres of mountain orchards to complete the water conservancy projects generally need to invest 4-5 million investment, instead of using this method can save more than 40,000 yuan investment, but also save wells matching wells, utilities costs. Compared with artificial water-drenched trees, reducing the amount of labor. 2. Save the amount of water required. Generally 40 acres per mu orchard
