摘要
对马铃薯克新一号原种采用地膜覆盖和露地两种栽培措施进行试验,研究比较其出苗时间、根系土壤水分含量变化规律及其生物产量、单产和商品薯率的影响,结果表明:地膜覆盖与露地栽培相比,马铃薯生长期缩短15d左右,植株干物质含量明显增加,马铃薯块茎产量每667m2较露地增产605.8kg,商品薯率提高19.2个百分点,具有明显的增产、增效优势。
A one year field experiment was conducted once to access the effect of plastic film mulching on emerging time, changes of water content in soil surrounding root, biological yield,average yield and commodity rate of potato in dry land. The results showed： Comparing with open field cultivation,plastic film mulching cultivation reduced the growth period of potato by 15 days,increased the dry matter content of the plant significantly,improved both the average yield of tubers by 605.8kg/667m^2 and the commodity rate of tubers by 19.2%.Plastic film mulching cultivation increased not only the yield but also the economic benefit.
