山区果园土层薄,保肥保水性差,自然降雨分布极不均衡,而且灌溉条件有限,大部分果树处于干旱缺水状态,严重制约了果树的生长发育,因此,采取抗旱节水措施十分必要。 1.增厚土层。山地果树土层薄保水性差,水土流失严重,必须采取多种措施,如修“围山转”工程,修水平梯田、培土、施有机肥,深翻扩穴压绿肥,打眼炮震松土扩穴栽值、加大树盘等,不仅增厚了土层,改善了土壤理化性质,促进根系和新梢生长,而且大大提高了果树抗旱能力效果非常理想。 2.截蓄天然降水:采取层层截蓄的办法,减少 Mountainous orchard thin soil, poor water retention, poor distribution of natural rainfall, and limited irrigation conditions, most of the fruit trees in arid and water deficit, seriously hampered the growth and development of fruit trees, therefore, to take drought-saving and water saving measures are necessary. Thicken the soil The mountainous soil has poor water-holding capacity and serious soil erosion, so many measures must be taken, such as repairing the “surrounding hills” project, repairing the terraced fields, cultivating the soil, applying organic fertilizer, It is not only thicken the soil layer, improve soil physical and chemical properties, promote the growth of roots and shoots, but also greatly improve the fruit tree drought resistance effect is very satisfactory. 2. Cut natural precipitation: take layers of savings approach to reduce
