摘要
采用单因素随机区组设计,研究不同地膜覆盖对龙薯28号主要性状和产量的影响。结果表明:覆盖地膜可提高龙薯28号的平均蔓长、单株分枝数及薯块干物率,能极显著提高鲜薯、薯干、淀粉产量;覆盖透明地膜处理的产量和经济效益最高,每667m2鲜薯产量为2 385.80kg、薯干产量938.67kg、淀粉产量662.08kg、经济效益为2 851.60元。
Using the single factor random block design,the effects of different plastic film mulching on the main characters and yield of‘Longshu No.28’were studied.The results showed that mulching with plastic film could increase the average vine length,number of branches per plant and dry matter percentage of‘Longshu No.28’,and extremely significantly increase the yield of fresh potatoes,dried potatoes and starch.The yield and economic benefits per 667 m 2 of mulching with transparent plastic film were the highest,with 2 385.80 kg of fresh potatoes,938.67 kg of dried potatoes,662.08 kg of starch,and 2 851.60 Yuan of economic benefits.
