研究结果表明：①１００～１０００ｍｇ／ｋｇＰＶＡ能有效地形成土壤水稳性团粒（以下简称“成团”）；②ＰＶＡ能明显减少土壤水分散失量；③ＰＶＡ可增加酸性～弱酸性土壤ｐＨ值；④ＰＶＡ能显著减少土壤钾的淋失量
The results showed as follows: (1) 100 ~ 1000mg / kgPVA can effectively form soil water-stable aggregates (hereinafter referred to as “clumps”); ②PVA can significantly reduce soil water loss; ③PVA can increase the acidic ~ weak acid soil pH value; ④PVA can significantly Reduce soil potassium leaching loss
