沂水县花生种植区农田残膜量调查及回收对策分析

The Peanuts Farmland of Residual Film Investigation and Analysis of Recycling Countermeasures in Yishui County

针对花生种植过程中大量使用地膜,秋后残膜回收不彻底,易造成土壤“白色污染”问题,本文对沂水县域内花生种植主产区7个乡镇21个典型样点取样调查分析,得出残膜在农田土壤的分布特征和影响因素,残膜主要分布在0~15cm的上层土壤内,约占残膜总量的76%,耕层残膜量介于10.85~35.05kg·hm^(-2)。研究结果为该地区农田残膜污染治理及防控提供科学依据。

In view of the extensive use of plastic film in the process of peanut planting, and the incomplete recovery of residual film after autumn, it is easy to cause the problem of "white pollution" of soil. In this paper, the sampling survey and analysis of 21typical sampling points in 7 townships and towns in the main peanut planting areas in Yishui County. The distribution characteristics and influencing factors of the residual film in the farmland soil. The residual film is mainly distributed in the upper soil of 0~15 cm, accounting for more than 76% of the total residual film. The amount of the residual film in the plough layer is between10.85~35.05 kg·hm^(-2). The research results provide a scientific basis for the control and prevention of residual film pollution in farmland in this area.
