春大豆应用全生物降解地膜试验

Experiment on Application of Fully Biodegradable Plastic Film in Spring Soybean

全生物降解地膜是一种环保新型地膜,具有自然降解减轻污染的功能优势。浙江省慈溪市蔬菜种植面积大,地膜应用广泛。为正确评价不同类型全生物降解地膜在慈溪市春大豆上的应用效果,本研究引进了不同厂家/原料配方的2个厚度的全生物降解地膜,通过观测田间降解情况和考察作物的生物性状与经济性状,结果表明,杭州新光塑料有限公司/上海弘睿生物科技有限公司0.010 mm的白色降解地膜适宜在春大豆上应用,覆盖后60 d左右进入开裂期,春大豆结荚性好,每667 m^(2)产量达到872.02 kg,比对照普通地膜处理增产178.92 kg,每667 m^(2)净增收益544.11元。

Biodegradable mulching film was a new type of environmentally friendly mulching film,which had the advantage of natural degradation and pollution reduction.The vegetable planting area in Cixi was large,and the mulching film was widely used.In order to correctly evaluate the application effects of different types of biodegradable mulching film on spring soybean in Cixi,two thickness of fully biodegradable mulching films from different manufacturers/raw material formulations were introduced and the field degradation was observed and the biological and economic characteristics of spring soybean were investigated the results showed that 0.010 mm white degradable mulching film of Hangzhou Xinguang Plastics Co.,Ltd./Shanghai Hongrui Biotechnology Co.,Ltd.was suitable for application on spring soybean.The plants got into the cracking period about 60 days after mulching,and showed good pod-setting.The yield per 667 m^(2) reached 872.02 kg,which was 178.92 kg higher than that of the control common film treatment.The net income per 667 m^(2) was 544.11 yuan.
