五种不同遮阴方式试验结果表明 ,采用 1 .8m高棚遮阴网内套 4 0cm弧形矮棚薄膜遮阴可较好地保湿控温遮光 ,明显优于传统竹帘遮阴方式和目前国内流行的矮棚双层网膜遮阴方式、高棚单网遮阴方式 ,其扦插成活率、苗木出圃率分别提高了 2 1 %～ 60 .5%、1 7.7%～ 73 .1 %,平均苗高差异极显著 ;且减少管理用工 ,节约用水 ,极大地降低了成本 Five different shading test results show that the use of 1 .8 m high shed shading net cover 4 0cm arc canopy shading film can better moisture control temperature shading, significantly better than the traditional shades of shade and the current The prevalence of double shelled double-shelled shade in the country and the shading of single shelter in high shelters increased the cutting survival rate and nursery stock yield by 21.1% -60.5%, 7.76% -73.1% The average difference in seedling height is very significant; and reducing management labor, saving water, greatly reducing costs
