为保持水土和绿化荒山荒坡,解决三料(燃料、饲料、肥料)问题,近年来我们在干旱黄土丘陵沟壑区进行了红柳栽植试验。试验地主要是我站的梁峁坡,海拔1,600-1,800米,黄土层深厚,年雨量327.5毫米,年蒸发量1,430毫米,年平均气温9.5℃,极端最高39.1℃,极端最低-23℃,无霜期176天。红柳,又名柽柳,是一种丛生落叶灌木或小乔木,高可达5米。红柳根系发达,主根多达5-6条,深10米。侧根倾斜分布在1米以下,上层有细小须根、毛根,成网状分布在0.3-1米以内。发达的根系在干旱条
In order to maintain soil and water resources and afforest barren hills and slopes and solve the problem of three materials (fuel, feed and fertilizer), in recent years we conducted the experiment of planting red willow in the arid loess hilly region. The main test site is the Beam slope of I station, 1,600-1,800 meters above sea level, deep loess with annual rainfall of 327.5 mm and annual evaporation of 1,430 mm, annual average temperature of 9.5 ° C, extreme maximum of 39.1 ° C, extreme minimum of -23 ° C, frost-free period 176 days. Tamarisk, also known as Tamarisk, is a bushy deciduous shrub or small tree up to 5 meters high. Hongliu root developed, the main root up to 5-6, 10 meters deep. Lateral root tilt distribution in less than 1 m, the upper has small fibrous roots, hair roots, into a network of distribution within 0.3-1 meters. Developed root system in the drought
