摘要： 南昌风沙化土地主要有风成沙丘(沙地)和沙质沉积阶地(硬梁地)两大类。风成沙地粗沙含量高于80%,0~80厘米土层田间持水量低于5%,水分渗漏速度39.44毫米/分,有机质含量低于0.12%。硬梁地粗沙含量38~64%,田间持水量10~14%,有机质含量低于0.4%。缺乏Ca、Mg、B、N等元素。风沙化土地不适宜果树生长,植株矮小、枝条纤弱、生长量小、经常表现出缺素症,葡萄生长率低于7%。果树正常生长必须补充大量的水、肥、才能取得应有的经济效益。可采用客红壤土改良沙土、保水袋栽培、下垫隔水材料、间种绿肥等方法来提高风沙化土地地力。

Abstract: There are two kinds of blownsand lands in Nanchang,i. e. eolian sand land and sedimentary sand terrace. In the eolian sand land the minimum content of coarse sand is 80 percent,the maximum field capacity 5 percent at the depth of O-80 cm,the permeability of water 39.44ml/mim and the maximum content of orgamic matter 0.12 percent. In sedimentary sand terrace the coarse sand content varies between 38-66 percent,the maximum content of orgamic matter 0.4 perceut, the field capacity ranges from 10-14 percent. Fertillizer elements,such as Ca,Mg,B,and N are deficient in blown-sand land. Blownsand land is not suitable for fruit trees. The maximum growth rate of grape is 7.0 percent. Fruit shoots are tiny and the tree was dwarf. It is necessary to irrigate and apply fertillixers for proper growth of fruit trees on blownsand land. Such measures as put red loamy soil into blownsand use moisture-holding bag water-proof barrier and interplant g green manure have been used to overcame above mentioned problems.
