侧柏是我省的乡土树种,是荒山造林的主要树种之一。侧柏适应性很强,在土壤肥厚、水分充足的条件下,生长速度不次于油松;在土壤瘠薄、严重干旱的条件下,虽不能长成大材,也能起到绿化和保持水土的作用。 过去,侧柏造林只习惯在雨季进行,这就阻碍了绿化速度,延长了绿化时间。近一、二年来,迁安县长城沿线社队的林业科学实验小组遵照毛主席关于“绿化祖国”的伟大教导,展开了以扩大侧柏造林季节为中心的常年造林实验,结论是:侧柏造林从早春苗木返青到晚秋苗木变色都能成活,其成活关键不在于季节,而在于水份是否充足。根据冷口、东新庄、
Platycladus is a native species in our province, is one of the main tree species afforestation. Platycladus oriental adaptability is strong, in the soil hypertrophy, adequate water conditions, the growth rate of secondary to Pinus tabulaeformis; infertile soil in the barren, severe drought conditions, although not grow into large, but also play a green and maintain soil and water Role. In the past, arborvitae afforestation only used to carry out in the rainy season, which hindered the speed of greening, extending the greening time. In the recent one or two years, the forestry science experimental team of the communes and brigades along the Great Wall along Qian’an County started the perennial afforestation experiment centering on the expansion of the planting season of Platycladus orientalis in accordance with Chairman Mao’s great teaching on “greening the motherland.” The conclusion was: From early spring seedlings turn green to late autumn seedling discoloration can survive, the key to its survival is not the season, but rather whether the water is adequate.
