生物降解地膜在小京生花生上的应用

Preliminary report on the application of biodegradable film on Xiaojingsheng peanut

为探讨生物降解膜在小京生花生上应用的适应性,选取黑、白2种颜色,不同厚度的生物降解膜,以普通地膜为对照,开展随机区组试验。结果表明,前期处理A1与处理A3、A4之间出苗率存在显著差异,后期无显著差异。不同厚度的黑色、白色生物降解膜和普通膜覆盖下的小京生花生结荚率、产量均没有显著差异。但生物降解膜可自然降解,不用收集残膜,节省劳力,减少土壤、环境污染,可以作为小京生生产中普通地膜的替代产品。

In order to explore the adaptability of biodegradable film in the application of Xiaojingsheng peanut,two colors of black and white,biodegradable films with different thicknesses were selected,and ordinary plastic film was used as the control,and a randomized block experiment was carried out.The results showed that there was a significant difference in seedling emergence rate between A1 and A3 and A4 in the early stage,but there was no significant difference in the later treatment.There was no significant difference in podding rate and yield of peanut under the mulching of black and white biodegradable film of different thicknesses and ordinary film.However,the biodegradable film can be degraded naturally,without collecting residual film,saving labor,reducing soil and environmental pollution,and can be used as a substitute for ordinary plastic film in the production of Xiaojingsheng.
