科左中旗春季造林从4月初到5月1日前只有20多天。这段时间恰是大风季节,也是东方金龟子对新造幼林的严重危害期和牲畜没拢群时期。为了躲过“三害”,把春季造林时间延长到5月上中旬,我们采取了低温贮藏苗木的方法。 Kezuozhongqi afforestation from early April until May 1 only 20 days. This period of time is just the windy season, which is also the period when the beetles of Eastchase severely damage the newly-created young forest and the livestock are not in full swing. In order to avoid the “three pests” and extend the planting time in spring to the middle of May, we adopted the method of storing seedlings at low temperature.
