我国栽培果树的立地条件一般较差,主要分布在丘陵山地,常受干旱危害。为此,特介绍几种可行的节水栽培措施。 1.选用耐旱砧木和品种培育耐旱苗木 以苹果为例,华北的西府海棠和楸子、西北的变叶海棠、西南的滇池海棠和锡金海棠等,都是抗旱性强的砧木;从国外引进的矮化砧木M7,也抗旱性强,适应性广。较抗旱的苹果品种有:赤阳、秦冠、金冠、国光等。在利用时要注意砧木与接穗的适宜组合。此外,以
The cultivation of fruit trees in our country is generally poor site conditions, mainly in the hills and mountains, often endangered by drought. To this end, special introduction of several feasible water-saving cultivation measures. 1. Selection of drought-resistant rootstocks and varieties of drought-tolerant seedlings to grow apples, for example, North China’s Begonia and Catalpa bungei, Northwest lobular begonias, southwest of Dianchi Begonia and Sikkinensis, are strong drought-resistant rootstocks; from abroad The introduction of dwarfing rootstock M7, also strong drought resistance, wide adaptability. More drought-resistant varieties of apples are: red sun, Qin crown, Golden Delicious, Guoguang and so on. In the use of pay attention to the appropriate combination of rootstock and scion. In addition,
