雨季,是荒山沟壑造林的重要季节。我国北方地区春、秋季造林常因土壤含水量少而成活率不高。利用雨季降水多、土壤墒情好、空气湿度大的特点,开展大面积植树造林,比春季和秋季易于成功。一、雨季适于栽松柏类的针叶树。辽宁省建昌县古迹营子林场和黑山林场,1983、1984、1985连续三年雨季在20°以下北坡营造油松林共计1500余亩,成活率比春季造林平均高
Rainy season, is a barren ravine afforestation an important season. The spring and autumn afforestation in the northern part of our country is often not so successful because of the low soil water content. Utilizing the features of precipitation in the rainy season, good soil moisture and large air humidity, afforestation in large areas is easier than in spring and autumn. First, the conifers suitable for planting conifers in the rainy season. In 1983, the snowy season of 1983,1984,1985 for three consecutive years in the north of 20 degrees below the north slope to create a total of more than 1,500 acres of Pinus tabulaeformis, the survival rate higher than the spring afforestation average
