甘肃省中部干旱山区,气候干旱,年降雨量平均在250—400毫米之间。大部分地区人、畜用水全靠降雨时蓄积的窖水,因此育苗有很大的困难。为解决干旱山区育苗问题,我们从1978年起,开展迳流灌溉育苗试验。所谓迳流灌溉育苗,就是利用山地的自然坡面,人工稍加整修后,铺设塑料薄膜等材料,用卵石压
In the arid mountainous area in central Gansu Province, the climate is arid with annual rainfall averaging between 250-400 mm. In most areas, livestock water is entirely dependent on the cellar water accumulated during rainfall, so raising seedlings is very difficult. In order to solve the problem of breeding nursery in arid mountainous areas, we started the experiment of cutting irrigation and seedling nurturing since 1978. The so-called Shu irrigation flowering seedlings, is the use of natural mountain slopes, artificial a little renovation, the laying of plastic film and other materials, with pebble pressure
