穴贮肥水简单易行,投资少,收效大,具有节肥、节水特点,一般可节肥30%,节水70%～90%。在土层较薄、无水浇灌条件的山丘地应用,效果尤为显著,是干旱果园重要的抗旱、保水技术。具体做法如下:1.做草把。用玉米秸、麦秸或稻草等捆成直径15～25厘米、长30～35厘米的草把(要扎紧捆牢)。放在5%～10%的尿素溶液中浸泡透。2.挖贮养穴。在树冠投影边缘向内50～70厘米处挖深40厘米、直径比草把稍大的贮养穴。依树冠大小确定贮养穴数量,冠径
Secrets stored fertilizer easy, less investment, large effect, with fertilizer, water features, the general savings of 30%, saving 70% to 90%. In thin soil conditions, no watering conditions hillside application, the effect is particularly significant, is an important drought in drought orchards, water retention technology. The specific practices are as follows: 1. With corn stalks, straw or straw bundled into a diameter of 15 to 25 cm, length of 30 to 35 cm grass (to tie tight tied). Put 5% ~ 10% of the urea solution soaked thoroughly. 2. dig storage hole. In the canopy projection edge of 50 to 70 cm dig deep 40 cm, diameter slightly larger than the grass storage points. According to crown size to determine the number of storage points, crown diameter
