摘要:

为研究全生物降解地膜对农田水热特性及甘薯产量的影响,设置田间定位试验,分析露地(M0)、聚乙烯地膜(M1)和全生物降解地膜(M2)对甘薯田土壤含水量、土壤温度及甘薯产量和经济效益的影响。结果显示,覆膜处理(M1和M2)能提高土壤水分和土壤温度,但茎叶盛长期后,保墒和增温效果逐渐减小,但仍高于露地处理(M0);同时,全生物降解膜处理(M2)能有效提高商品薯产量,平均净收入最高,较露地处理高53649.6元/hm2,较聚乙烯地膜处理高4480.8元/hm2。说明,全生物降解地膜能代替聚乙烯地膜用于甘薯种植,可在生产中推广应用。

Abstract:

In order to study the effects of whole biodegradable film on soil temperature and soil moisture in sweet potato field and sweet potato yield, a field positioning experiment was set up to analyze the effects of bare land (M0), polyethylene mulching film (M1) and whole biodegradable film (M2) on soil moisture, soil temperature, sweet potato yield and economic benefit. The results showed that, film mulching (M1 and M2) could increase soil moisture and temperature, but the effects of soil moisture retention and temperature increase gradually decreased after the stem and leaf vigorous growing period, which were still higher than those of bare soil (M0). At the same time, the whole biodegradable film (M2) could effectively improve the yield of commodity sweet potato, and the average income was the highest, 53649.6 yuan/hm2 higher than that of bare land treatment, 4480.8 yuan/hm2 higher than that of polyethylene film treatment. To sum up, whole biodegradable film could replace polyethylene mulching film in sweet potato planting and could be popularized in production.
