干旱荒漠区樟子松夏季造林可行

The Summer Afforestation of Pinus sylvestris in Arid Desert Area is Practicable

春秋造林季节短促,劳力紧张,为此开展了樟子松干旱荒漠区夏季造林造林试验。结果表明:干旱荒漠区夏季造林可行。樟子松带土球苗木7月中下旬造林,成活优于春季而与秋季相近,定植后一个月内每7 d灌水1次,成活率可达95%以上;新梢生长优于春、秋季造林,次年新梢生长量可达13 cm。樟子松夏季造林达到造林标准,在干旱荒漠区造林实践中可行。

The spring and autumn afforestation season is short and labor is tight,so the summer afforestation experiment of Pinus sylvestris var.mongolica was carried out in arid desert area.The results show that afforestation in summer is practicable in arid desert area.The afforestation started in mid-late July,the survival rate of soil-bulb seedlings of Pinus sylvestris var.mongolica was better than that in spring and similar to that in autumn.The survival rate was more than 95% when irrigated once every 7 days within a month after transplanting.The growth of new shoot was better than that of spring and autumn,and the growth of new shoot in the next year could reach 13 cm.The summer afforestation of Pinus sylvestris var.mongolica reached the afforestation standard and was practicable in the practice of afforestation in arid desert area.
