沙地建立平欧杂种榛园初期，通过在防护林带内种植玉米等高秆作物试验，结果表明：榛园建园初期，在防护林带内种植玉米等高秆作物并保留茎秆，可增强林带的防护能力，大幅度提高造林成活率和保存率，减少抽条现象的发生，减轻风沙对幼树的为害，促进树木的生长。玉米防护带可降低风速，减少园内的水分蒸发，提高了温湿度，有利于改善榛树授粉条件，延长了授粉时间。
沙地建立平歐雜種榛園初期，通過在防護林帶內種植玉米等高稈作物試驗，結果錶明：榛園建園初期，在防護林帶內種植玉米等高稈作物併保留莖稈，可增彊林帶的防護能力，大幅度提高造林成活率和保存率，減少抽條現象的髮生，減輕風沙對幼樹的為害，促進樹木的生長。玉米防護帶可降低風速，減少園內的水分蒸髮，提高瞭溫濕度，有利于改善榛樹授粉條件，延長瞭授粉時間。

During the initial stage of establishing Corylus heterophylla Fisch .× C .avellana L .on sandland ,experi-ments of planting corn and other long-stalked crops in shelterbelts were conducted .Result shows that :during the initial stage of establishing park of hazel (Corylus heterophylla) ,planting corn and other long-stalked crops in shel-terbelt and retain the stem can enhance forest protection ,greatly improve the survival rate and preservation rate ,re-duce pumping phenomenon ,reduce sand damage to young trees ,promote tree growth .Corn protective belt can re-duce wind speed ,reduce evaporation of water in the park ,improve temperature and humidity ,extend the pollination time ,improve the pollination conditions of hazel ,extend the pollination time of hazel .
