优良防沙治沙植物——沙打旺沙打旺也称直立黄芪，为豆科黄芪属多年生草本植物，是饲草、绿肥、防风固沙、保持水土等兼用作物。株高一二米，可由根茎和茎的中部和上部分枝形成大株丛。主根粗长，干旱地区5年生的植株根深可达6米，侧根较多，根幅达150厘米左右。叶为奇数羽状复叶，卵形或长圆形。总状花序，花为蓝色、紫色或蓝紫色。荚果三棱状圆柱形、长圆筒形或长椭圆形。沙打旺具有很强抗逆性和顽强的抗沙能力，在风沙吹打下仍能生长良好，故得名沙打旺或沙大王。沙打旺茎叶强壮，被风沙吹打后即使被损伤，或被风沙浅埋数日，以及被大风吹出部分裸露地面的根，都能继续生长。沙打旺这种顽强护沙的能力，被誉为重要的防沙固沙先锋植物。它的根系能从深层土壤中吸收水分和养料，能耐贫瘠和干旱的土壤。据观察，生长在贫瘠干燥、退化草地上的沙打旺，70天无雨情况下仍能生长良好。在沙砾质地、固定沙丘、河滩以及“破皮黄”、“白干地”等都能种植，所以具有“薄地犟”之称。在黑龙江省西部的碱性草原地带，pH值为8.9，含盐量0.3%，钠离子O.02%的苏打盐碱土地上生长良好。盐碱地上种植沙打旺，能从土壤中吸走大量盐分，增加土壤有机质，降低土壤中的含盐量，使盐渍化土壤得到改善。沙打旺为多年生短寿命植物，第二年生长较快，第三年生长最盛，随着生长年限的增加，根部和根茎老化。第四年生命力降低，生长缓慢，分枝减少，陆续死亡。生长到第六年，有大批植株死亡。它不耐湿，不抗涝，水淹会引起烂根死亡。对土壤要求不严，通常以黑钙土、栗钙土、黑黄土为宜。在白浆土、棕壤、红壤、黄壤和盐碱土等肥力较低的土壤上也可以种植。沙打旺为喜温抗寒植物，从发芽出苗到开花成熟，需10℃以上的有效积温不能低于3500℃。适宜的生长区域为温带，也能顺利生长在寒温带。种子发芽的最低温度为8℃，在27℃至30℃的温度下发芽出苗速度最快，但幼苗较为细弱，以18℃至22℃最为适宜。沙打旺喜光性强，光照充足，植株高大，多枝，颜色浓绿，结实植株增多；光照不足则植株徒长，茎细枝少，颜色淡黄，结实植株减少。苗期不太耐阴，在疏林中常因光照不足发生死苗现象，但抽茎后耐阴性增强。沙打旺真叶期约持续30至40天，干旱条件下可达45至50天，是沙打旺生长最缓慢时期，株高仅8至10厘米，但根生长较快，入土深可达30至50厘米。（来源：中国花卉报-05-27）
