山区岗坡次地一般都是旱地,又有一定坡度,水土流失严重,土地瘠薄。现介绍几种简便而又实用的节水栽培方法: 一、上坑下埂蓄水保土法。雨季到来前,在每棵树的上面,沿树冠投影外围挖一弯月形坑,根据树龄坑深为60~100厘米,长与树冠直径基本相等,宽1米左右,将挖出的土放到树的下面,沿树冠投影打一弧形埂,埂要中间粗,两头细,用脚踏实,以防雨水冲毁。
Hillside slopes are generally dry land, there is a certain slope, serious soil erosion, barren land. Now introduce several kinds of simple and practical water-saving cultivation methods: First, the pit under the water storage and soil conservation law. Before the arrival of the rainy season, above each tree, a crescent-shaped pit was dug out along the crown of the canopy. According to the age of the pit, the depth was 60-100 cm. The length of the tree was about the same as the diameter of the canopy. The width of the crown was about 1 meter. To the tree below, hit a curved crown projected along the crown, 埂 to the middle of rough, two thin, with feet down, to prevent the rain washed away.
