对上虞市海涂实验农场农田林网防护效益的测定，结果表明通风结构审林带防风效能达到３１．０％左右；在八九月份高温干旱季节，林网内增加相对湿度约１．８％。林带背风而树高２～３倍地区为林带增产作用的显著范围，棉花产量比对照区增产１３．０％～３８．１％，除林缘等胁地外，受林带有利影响测试区棉花产量平均增产８．４％。
The results showed that the windbreak effectiveness of the forest belt in the ventilation structure reached about 31.0%. In the high temperature and drought season in August and September, the relative humidity increased by about 1.8% in the forest net. The forest leeward and the tree height 2 ~ 3 times the area for the significant effect of increasing yield of cotton belt, cotton yield increased 13.0% ~ 38.1% than the control area, in addition to forest edge threatening, affected by forest belt cotton yield An average increase of 8.4%.
