内蒙地区全年干旱少雨,风沙害严重。但在夏季,由于太平洋及东南沿海高压湿润气流流向大陆,使七、八月成为降雨集中的季节,而且日照长,温度高,为雨季造林提供了良好条件。雨季造林可采用油松、落叶松、樟子松等针叶树小苗植苗造林;柠条、沙棘、杨柴等灌木树种的直播造林;杨、柳树的嫩枝插条造林等方法。为提高雨季造林成活率,应做到以下几点:
Inner Mongolia was dry and rainy all year round with serious sandstorm damage. However, in the summer, due to the high-pressure humid air currents flowing to the Pacific Ocean and the southeast coast, it made July and August a rainy season, and the long sunshine and high temperature provided favorable conditions for afforestation in the rainy season. Rainy season afforestation can be Pinus tabulaeformis, Larix, Pinus sylvestris seedlings such as conifers afforestation; Caragana korshinskii, Seabuckthorn, Yang Chai shrubs direct seeding afforestation; young shoots of Willow twigs afforestation methods. In order to improve the survival rate of afforestation in rainy season, we should do the following:
