简介：Sanjiang平原是冲积泛滥平原的一个广阔区域；在东北Heilongjiang省的低山。因为在过去的过多的陆地开垦，整个森林区域；质量减少了。在持续开发的看法，这篇论文以开发潜力为非木材福雷斯特产品分析了可能性，市场，社会效果；在Sanjiang平原的几个县的NTFP的地位。结果显示出那，活跃开发；为NTFP的管理是到怎么平衡沼泽地保存的一种乐观选择；持续经济开发。

简介：一个地实验被进行在有或没有稻草mulching在充满的土壤和非充满的土壤栽培的大米学习水使用效率和农学的特点。米饭在充满的耕作(FC)下面使用的水的Thetotal数量是2.42并且3.31倍于那由在有或没有稻草mulching的non-fiooded耕作下面的米饭分别地。Theaverage水渗出物是在充满的耕作，在没有稻草地面覆盖(ZM)的充满thenon的耕作下面的4750m~3/ha和在有稻草地面覆盖(SM)的非充满的耕作下面的4680m~3/ha下面的13560m~3/ha。在SM处理的土壤水分蒸发蒸腾损失总量仅仅分别地是theFC处理和ZM处理中的38.2%个和63.6%。与ZM处理相比，稻草mulching显著地每植物，直根长度，粗野的根长度和根增加了叶面积每米饭的植物弄干重量。在SM处理下面的最高的谷物收益(6747kg/哈)接近了在充满的土壤栽培的ther冰(6811.5kg/哈)。然而，在ZM处理下面的收益(4716kg/哈)在FS处理和SM处理下面是比那低得多的。水使用效率和灌溉用水使用效率的顺序两个都如下：SM>ZM>FC。
