摘要
通过对准噶尔盆地南缘无灌溉造林关键技术进行研究,结果表明:无灌溉造林首选树种为梭梭;无灌溉造林应先选择靠近绿洲的流动沙丘造林;无灌溉造林合理初植密度梭梭应为2m×2m或2m×3m,沙拐枣应为2m×3m;造林6~7a后,梭梭母树开始自然更新;北疆无灌溉造林适宜季节以秋季第一场雪前造林效果最好。
Key technology about non-irrigation afforestation in southern margin of the Zhunger Basin were studied. Result shows that the first choice for non-irrigation afforestation is Haloxylon ammodendron;moving dunes near the oasis should firstly be selected for non-irrigation afforestation; the reasonable planting density of non-irrigation afforestation for Haloxylon ammodendron should be 2 m ×2 m or 2 m ×3 m and that for Calligonum rnongolicum should be 2 m ×3 m;Haloxylon ammodendron mother trees start natural regeneration after 6-7 a for afforestation;optimal season for non-irrigation afforestation in north Xinjiang which can obtain the best result for afforestation is before first snow.
