三种PPC降解地膜与普通地膜在花生上的应用效果对比

Comparison of Application Effect of PPC Degradation Film with Common Film on Peanut

大田条件下,采用普通白膜、黑色地膜和PPC1、PPC2、PPC3号降解膜等五种不同类型地膜覆盖栽培,以露地不覆膜为对照,研究不同类型地膜覆盖栽培对花生产量品质的影响。结果表明,PPC3号降解膜具有极好的降解效果,但增产效果较差,不能很好地发挥地膜覆盖栽培应有的增产增收优势;PPC1号膜具有较好的降解效果,较露地栽培增产13.43%,达极显著水平,但较普通黑、白地膜及PPC2号膜覆盖栽培减产均达极显著水平;PPC2号膜具有较长的覆盖时间,较露地增产26.09%,达极显著水平,但较普通黑、白地膜减产分别达显著和极显著水平。

Study on different material film effect on peanut yield and quality effect,including ordinary white,black film and biodegradable film with bare land as control.The results showed that the PPC3 biodegradable film had excellent degradation effect,but the effect of increasing production was poor,and it could not give full play of the film to the advantages of increasing production and increasing income;PPC1 film had better degradation effect,and increased yield as 13.43%compared with the bare land,reaching a very significant level,but it reduced yield significantly compared with the ordinary black,white film and PPC2 film;The PPC2 film had a long covering time.The yield increased by 26.09%than that in the bare land,but it was significantly higher than that of the ordinary black and white film.
