在覆膜和不覆膜的条件下种植同一种作物——小白菜,2个月后对土壤和作物进行分析,结果发现土壤的理化指标中有机质含量没有变化,覆膜条件下微生物数量多于对照组,其他理化指标如土壤含水率、烧失量和pH对照组比覆膜组分别高0.87%,37.32%和14.5%,对其原因进行分析;在作物的长势上,从植株的根重、鲜重和株高相较,覆膜比对照组分别重6.01%,重21.85%和高14%。故覆膜条件下更利于作物生长,能让作物增产。
The same crop, Chinese cabbage, was planted under mulching and non-mulching conditions. After two months of soil and crop analysis, the results showed that there was no change in the organic matter content in the soil physical and chemical indicators, and the number of microorganisms in the mulching film was more than The control group and other physical and chemical indicators such as soil water content, loss on ignition and pH control group were 0.87%, 37.32% and 14.5% higher than the control group respectively, and the reasons were analyzed. On the condition of crop growth, The fresh weight and plant height were 6.01%, 21.85% and 14% higher than the control group respectively. Therefore, it is more conducive to crop growth under the condition of film mulching, and can increase the yield of crops.
