摘要:
在辽宁省内不同地区、不同降雨和不同土壤条件下，采用3区组3因素2水平正交设计的聚丙烯酸胺施用试验，结果表明：在6°、10°、15°坡上施用聚丙烯酸肤的保上率分别为77%、67%、57%；平均每hm2保水量为153m3；3种坡度的保肥率分别为80%、65%、55%；坡耕地平均粮食的增产幅度为10%。
Abstract:
Under various region, rainfall and soil conditions of Liaoning province,polyacrylamide application experiment was carried out by using 3 blocks, 3 factors and 2 levels across design plan. The results showed that soil application of polyacrylamide at 6°, 10° and 15° hilly fields has a soil conservation rate of 77%, 67% and 57% respectively. The average water conservation per hm2 area is reached at 153 m3. The soil fertility maintaince rate for three hilly fields is 80%, 65 % and 55% respectively. The average increased grain yield at hilly fields is more 10 percent.
